How to choose a roller chain for a conveyor

When choosing a roller chain for your conveyor, the easiest way is to refer to the horsepower and RPM charts. The horsepower and rpm of the small drive sprocket will determine the size and number of teeth of the chain. Conveyor chains are available in a variety of options, including moving products horizontally, vertically, or around a bend radius. When choosing a conveyor chain, consider the purpose of the chain. For example, if you’re delivering products to customers’ doorsteps, you might choose chains that can move products up and down a hallway or warehouse.

Double pitch

Double pitch roller chains are a popular way to drive agricultural equipment. It has twice the pitch of a standard roller chain and is ideal for light-duty drives. Extended pitch increases performance at lower speeds, but requires fewer components per foot than standard single-pitch chains. Compared to single-pitch roller chains, double-pitch chainplates are longer and are suitable for lighter loads. Read on to learn more about double pitch chains and how they can improve your operation.
The most common type of conveyor chain is double pitch. It is used in the auto parts industry, as well as in the precision machinery industry. It is made from the same components as the standard drive roller chain, except it has longer side plates. Double pitch chains are often used on slow-moving conveyors to reduce the stress placed on them. Industries that commonly use double pitch conveyor chains include airport equipment manufacturers, lumber mills, and fruit packing plants.
RS series roller chains are manufactured from high-quality stainless steel. It has excellent chemical and abrasion resistance and is available in a variety of cord lengths. RS sprockets have over 30 teeth. They contain all the necessary connection links for easy installation. PEER Chain offers double pitch roller chain attachments including pre-stretched chains, sprockets, and other attachments.
Double pitch roller chains have several advantages over standard chains. Double pitch chains have double the pitch, making them ideal for conveying applications such as conveyors. In addition to that, it also provides ANSI-compliant styles. These chains also have free connection links. When shopping for a double pitch roller chain, be sure to choose the one that fits your requirements and budget. They will last longer and save you money in the long run.
Double pitch roller chains to ANSI standards feature oversized rollers. These chains are best suited for applications where the product is mounted on top of the chain. They are ideal for agricultural applications where cotton is on top of the drum. Also, this type of chain is used in light-duty conveyors and agricultural applications. You can find double pitch roller chains in a variety of sizes and styles. And, as long as you know what you want, you’ll be happy with the results.

Self-lubricating

Self-lubricating roller chains eliminate the need for manual relubrication, providing long-lasting operation and reducing maintenance costs. These chains are particularly popular in industries such as the food and beverage industry, textiles, printing, and sawmills. They can also replace standard roller chain drives and conveyor chains. Manufactured to the specific standard ISO R606, these chains are ideal replacements for conventional chains. PC chains are particularly beneficial for food and beverage production and packaging applications due to their anti-corrosion properties.
Self-lubricating roller chains meet ISO, ASME/ANSI, and DIN standards. They are interchangeable with standard chains of the same size and shape and can be used in a variety of industrial applications. Self-lubricating chains have special oil-impregnated sleeves to reduce maintenance time. These chains are also suitable for applications where cleanliness is an issue.
Self-lubricating roller chains are manufactured with unique RS attachments. Rather than a traditional roller chain with an external lubricating ring, this type of chain retains the lubricant within its bushings. During operation, the application generates heat, heating the lubricant, which flows out of the pin and bushing area. Therefore, CZPT roller chains are ideal for certain food conveying applications.
In addition to self-lubricating roller chains, carbon steel, stainless steel or nickel-plated steel are also available. Self-lubricating roller chains are available in different sizes depending on the application, including 0.375″ wide profile straight-chain, extended pin chain, and four-link. In addition, these chains are also available in ANSI and BS chain specifications.

Accumulation

Whether you need to move large or small loads, accumulating roller chains are a viable solution. This chain conveyor is designed with low back pressure to transport large and bulky items with minimal noise. Free-running rollers within the chain help create a smooth build-up surface. These chains are available in a variety of options, including accumulating rollers of different pitches.
The accumulation and release roller chain 14 includes an upper part 15 and a lower part 16. The upper part 15 rests in the upper subspace 28, while the lower part 16 rests on the top side 20 of the profile. As the upper belt 15 rolls around the accumulation roller chain 14, it aligns with the lower chain 16 to form a continuous receiving space. This arrangement allows the accumulation roller chain 14 to rest on the top surface of the support profile 11.
A cumulative roller chain consists of many individual parts. Each section of the chain has an elongated cylindrical shape and is connected to each other by hinged joints. Each chain section also has an accumulation and release roller associated therewith. Each roller protrudes from the upper side 20 and the lower side 21 of the chain portion. The accumulation rollers are movable about an axis 22 extending transversely to the longitudinal axis of the chain.
A feature of the stacking and releasing roller chain is its simplicity. The conveyor has a profiled section that is permanently divided into two cross-sectional spaces. The bottom space is closed from all sides. The upper space accommodates the conveyor line. The contoured portion includes an opening that guides the bottom strap. A shunt can also be inserted between the two sections. The accumulating roller chain system is a convenient and versatile way to move bulky items.
There are many different types of accumulating roller chains. Some chains have offset rollers for optimal load distribution. Others have protection to prevent machine wear. Some run without lubricant, which is a safety advantage. In addition to protection, cumulative chains can also provide protection. The side bow version of the accumulation and release roller chain with offset accumulation and release rollers is designed for conveyor systems with very small bend radii.
chain

Without bushing

Bushless roller chains are the most common type of industrial chain. They are simple in design and require only regular maintenance. Regular maintenance includes lubricating, assessing wear, and replacing worn sprockets. For more information, please read the following information:
The outer chainplates and the inner chain plates are alternately arranged in pairs. The connecting pin extends through the hole in the inner link plate. The rollers thus positioned can be rotated on the connecting pins. Oil provided between the outer circumferential surfaces of each connecting pin serves to lubricate the chain. This system reduces noise and wears caused by collisions between inner chain plates and sprockets.
Compared to traditional roller chains, bushings roller chains have rollers around the bushing. These rollers are in rolling contact with the sprocket teeth, providing low friction and excellent wear resistance. To ensure smooth operation, bushings roller chains must be greased to prevent rust and keep the chain properly tensioned. Lubricated chains run smoother and last longer.
In a bushingless chain, the inner links are shaped like half bushings and ride on the rollers. The pins go through the outer plate and connect the inner links to the rollers. The outer plates overlap the inner links and open the pins. This system is also known as a heterochain. This type of chain is more common than traditional roller chains. If you are not sure which type of bushingless roller chain to choose, you may need to purchase an additional pair of inner chainplates.
Linerless roller chains may also include chain guides. In a bushingless roller chain, the outer and inner link plates conform to the surfaces of the guide rails. Thus, the large area of contact between the chain and the guide rail is eliminated, the friction loss is reduced, and the power transmission efficiency is improved. These properties make bushless roller chains more efficient and durable than traditional roller chains. It’s also less noisy. If you are looking for a chain with a lower noise level, a bushingless roller chain may be the right choice for you.

buy drive chain

Buying a drive chain requires a certain understading of its characteristics. This article discusses the different types of chains available, including Silent, Flat-top, and Duplex. By the end of this article, you should have a basic understanding of what each type of chain is for. First, here are some basic rules to keep in mind when shopping for a chain. To find the drive chain that best suits your needs, read on.

roller chain

Choosing the right roller chain for your drive chain depends on several factors. First, you have to determine the motor horsepower and rpm for the small drive sprocket. These values ​​determine the size of the chain and the number of teeth on the drive sprocket. Next, you need to determine the size of the conveyor chain, it can be the horizontal, vertical, or curved radius. Depending on your specific needs, you can also choose between two-strand or three-strand chains.
The roller chain of the drive chain must be properly tensioned. It should also have a proper lubrication system. Chain sag should not exceed two to four percent of the center distance (the distance between the two axles). Also, it shouldn’t make any unusual noises or obvious problems. One of the main reasons for excessive wear is the size of the load. Each chain has a specified maximum working load.
The maximum roller chain load must be less than 1/9 or 6 times the tensile strength of the drive chain. This amount should not exceed this threshold, as exceeding this level will result in chain plate fatigue. To avoid this, you should use a roller chain with a higher number of strands. Also, for high power requirements, a roller chain with a higher number of strands is recommended. One final tip for choosing a drive chain: it should not be used when there is a high risk of corrosion or rusting.
The materials used to manufacture roller chains vary according to the specific application. Common materials include steel and stainless steel. However, stainless steel is used in food processing machinery and other environments that require lubrication. Brass and nylon are also sometimes used. These factors determine the selection of suitable materials for the drive chain. If you are not sure which material to use, you can consult an industry professional. These professionals will help you choose the right chain for the job at hand.

mute chain

The design of the silent transmission chain is as follows: the large chain plates 2 are stacked one on top of the other in the direction of the chain length. The connecting rods are connected by connecting pins 3. The outermost and central guide plates 4 are fastened to the connecting pins 3 by means of rivets. This construction helps minimize friction on the sliding surfaces of the chain. Chainplate 2 of the silent transmission chain is usually made of stainless steel.
The link plates are made of steel and have a rectangular shape with pinholes 41. These guide plates have no teeth but have curved surfaces that guide the silent drive chain on the sprockets. In addition, the rear portion of the guide plate is higher than the portion of the chainplate. This feature improves pitch balance. The present invention is also applicable to silent transmission chains using rockers.
When it comes to chain design, it’s important to remember that silent drive chains are often used in automotive engines, especially timing and cam drives. This type of drive reduces noise and vibration due to its low engagement angle and links engagement with the sprocket. However, these applications are not limited to timing and cam drives; they can also be used for front-wheel power transmission. For example, silent drive chains are designed to resemble those used in NASCAR racing engines.
The design of the silent drive chain is based on the structure of the roller chain. Its components are standardized and manufactured according to pitch. There are single-row and multi-row versions. Quiet chains, also known as inverted tooth chains, are shaped to reduce noise from stretching. It’s also designed to minimize the amount of friction caused by small changes in pitch. Its teeth don’t slide against each other, so the chain is smoother and more durable.

flat top chain

One of the important parts of the flat top chainplate system is the hinge pin, which is used to fix the chainplate and is responsible for the smooth and efficient conveying of the chainplate. There are several types of hinge pins, including single hinge pins and double hinge pins. The single hinge pin is suitable for the chainplate with a small span and small bearing capacity, and the double hinge pin is suitable for the chainplate with a large span and high bearing capacity.
The side bending flat top chain is suitable for conveying large and medium workpiece pallets. They can be made of steel or plastic, each with its own advantages. Both chainplates are designed to convey material smoothly. Side curved flat-top chains can be used on straight conveyors. They have a low coefficient of friction and can transport weights up to 1.2 kg/cm. They can also be combined with HD profiles.
Flat top drive chains are usually made of plastic material and come in two types: tabletop chains and buffer chains. They come in a variety of widths, but the most popular are standard widths, ranging from 3.25 inches to 12 inches. MatTop chains are usually shipped in 10-foot lengths. They come in different styles, but they all have the same basic specs. Tabletop chains are designed for general conveying, while pad chains are used for specific applications. Solid top chains are suitable for conveying bulk materials, while wide pad chains can handle large volumes of fluids and/or solid-solid mixtures.
These chain conveyors can be used to convey, connect or lift small items. This type of chain is especially useful in industries where the product is hot or greasy. The modular design of these chains allows them to be configured in three dimensions, making them suitable for production changes and transitions. They also help reduce slack in the chain. Flat top chains are commonly used in final assembly and mechanical or paint restoration in the automotive industry.

double chain

Besides the roller chain, another type of chain drive is the double drive chain. This type of chain consists of a series of short cylindrical rollers connected together by side links and driven by gears called sprockets. This type of chain is very reliable and only requires a tractor with a high rpm PTO. It is manufactured by CZPT and is available in many different sizes and finishes.

Self-lubricating chain

Self-lubricating drive chains are the ideal solution for applications that do not require the relubrication of conventional chains. This maintenance-free roller chain features fully heat-treated components that increase the chain’s fatigue resistance and strength. It’s sintered alloy bushings are oil-impregnated, reducing the chance of premature wear and elongation. Its self-lubricating properties enhance its durability and work well even in hard-to-reach places.
CZPT self-lubricating roller chains feature preloaded sintered steel bearing pins and oil-impregnated sintered bushings. These chains are drop-in replacements for standard roller chains and run on the same sprockets as standard chains. In addition to being maintenance-free, self-lubricating roller chains are compatible with most existing sprockets and are ideal for demanding applications.
The O-ring chain concept was used to develop self-lubricating systems. It has two or more annular grease storage chambers. A self-lubricating bushing roller chain has an oil reservoir between its pin chain and the roller chainplate. A grease seal between these two plates isolates the moving parts and keeps the joints well lubricated. O-rings are made of special nitrile rubber, whose properties vary by application.
CZPT SLR conveyor chains and CZPT SLR drive chains have rollers on sintered bushings. CZPT SLR chains and SLR conveyor chains are self-lubricating and have a higher working load than standard ANSI chains. They may not be interchangeable with other self-lubricating chains from other manufacturers. Self-lubricating drive chains are the best solution for demanding industrial applications requiring heavy-duty, reliable conveying.
