Tip: Select chain with top rollers or side rollers to let discrete products idle while the conveyor continues to run. These stop discrete products even while the chain is still moving, and they do so with minimal friction and wear.Īccumulating conveyors are suitable for applications (such as assembly lines) that have products ride through several stations. One subtype of conveyor chain is the accumulating conveyor. Read the related article: What are Industrial Conveyors? Technical Summary The attachments let engineers put special fixtures or blocks onto the chain to serve specific conveyor functions. It’s also quieter than roller conveyors because its tabletop chain rides low-friction UHMW wear strips and return ways.Ĭommon versions are single-pitch attachment chain, double-pitch attachment chain, hollow-pin chain, curved-attachment chain and plastic-sleeve chain. It has longer life than conventional machines with rollers and fabric belts. (CHSC), which uses chain drives that function as accumulating sections. This is a Zone Touch case conveyor from Container Handling Systems Corp. These chains include extended pins or plates with tabs onto which parts or product-holding shoes can bolt. The most common conveyor chains are ASME-style (ANSI-style) attachment chains. Conveyor applications for chainĬonveyor chains come in myriad versions to move product horizontally, vertically or even around curved radii. Where roller chain must drive applications that need high precision, pick chain with precision roller bearings at each link connection. Where roller chain must drive applications that need long life without contamination, pick chain with self-lubricating subcomponents. From this, determine the roller chain size and number of teeth for the driver sprocket. Click to enlarge.įirst, obtain the motor horsepower and rpm of the small driver sprocket. The easiest way to select a roller chain is using horsepower charts. The ratio of the teeth determines the reduction in rpm … so to reduce rpm, the driven sprocket must be larger than the driver sprocket.įor example, if the driver sprocket has 15 teeth and the driven sprocket has 30 teeth, the ratio is 2:1, so the rpm is halved at the driven sprocket. This portion of the drive lets the designer build a system that’s either faster or slower by simply changing the ratio of teeth between the drive and driven sprocket. Most typical drive applications use an ASME/ANSI roller chain wrapped around a driver sprocket (connected directly to the motor or reducer) and the driven sprocket (often connected to a machine’s conveyor head-shaft). Roller-chain applications generally fall into two categories: drives and conveyors. More specifically, modern roller chains exhibit high wear resistance, fatigue strength and tensile strength. Manufacturers make and assemble each of these subcomponents to precise tolerances and heat treat them to optimize performance. This type of chain consists of five basic components: pin, bushing, roller, pin link plate and roller link plate. Read the related article: What are Roller Chains? Technical SummaryĬhain-based machinery abounds, but the most common industrial designs use roller chain. Lower inset, the inner surface on the bushings in Tsubaki’s PerforMax chain has lubrication grooves to extend chain life. Tsubaki) shows the subcomponents in a chain linkage. Roller chain is an engineered power-transmission component. Remote installations benefit from long-life chain that requires no lubrication, for example. Now, advances in precision and technology let designers use chains in more applications than ever. They are versatile and reliable components to drive machinery and convey products. || Engineers have used chains in motion systems for more than a century.
