Speed Variation
Chains are usually used at low speeds with large loads. Some common chain types and speeds include the following:
Transmission roller chain: less than 150 m/min. Small pitch conveyor chain: 10 to 30 m/min. Precision conveyor chain: less than 50 m/min. Top chain: 10 to 30 m/min. Free flow chain: 5 to 10 m/min. Large pitch conveyor chain: 10 to 30 m/min.
There are chains that are designed for high-speed operations. Here are some examples: • The chain used in balancer drives in automotive engines can run at 1,800 m/min., which is the same speed as a cog belt. Chain pitch is less than 8 mm. • Chain that drives the rear wheels of racing motorcycles operates at 1,500 m/min. • The chain for the camshaft drives in marine diesel engines operates at about 600 m/min. Chain pitch is greater than 100 mm. • The top chain that moves beer cans in breweries runs at 200 m/min. • Large pitch conveyor chains and block chains in steel processing plants can run at speeds of 330 m/min. The chain pitch is 150 mm. In each of these high-speed operations, the chain must be selected carefully. It’s important to consider not only the strength and wear resistance, but the type of lubrication required. When you set up a high-speed chain system, make sure you work with a reliable supplier, and ask to see some actual per- formance results for the chain you are considering.
