Qingdao chain factory

Qingdao motorcycle chain manufacturer of small make up you v. chain is one of the main parameters

　　Sprocket teeth

In order to improve the running smoothness chain transmission, to reduce the dynamic load, the small sprocket teeth more as well. But the small sprocket teeth also shoulds not be too much, otherwise = I will be very big, so that the chain breaks due to skip the earlier.

　　Qingdao motorcycle chain factory

　　Chain work after a period of time, wear make the pin, the sleeve and roller thinning, in under the action of tensile load F, the chain pitch of elongation. The chain pitch wound sprocket, chain after longer time move to the addendum circle d.

　　Even number for general chain section to avoid using transition joints. To wear the uniform, improve life, sprocket teeth with best link number co-prime, if cannot guarantee co-prime, also should make its common factor as small as possible.

　　The chain pitch

　　The bigger the chain pitch, theoretically the higher bearing capacity. But as mentioned in section: the higher the pitch, by changes in the rate of chain and chain link meshes into the chain caused by impact of dynamic load, the greater the carrying capacity makes chain and reduce the service life. So, should choose as far as possible when the design of chain, overloading when selecting the actual effect of fine-pitch row chain more often than coarse pitch selected single chain effect is better.

　　The center distance and the chain length

　　Chain transmission center distance is too small, the small Angle on the sprocket, meshing sprocket teeth is less at the same time; If center distance is too large, it is easy to make the chain jitter. Generally preferable center distance a = (30 ~ 50) p, the biggest center distance 80 p or less.

　　The chain length said with chain section number. Please take long formula can be derived by belt transmission link number calculated therefrom Should be rounded to an integer, it is better to take for even. Use type can be solve by center distance for a formula:

　　Chain for ease of installation and adjustment of the chain tension, general center distance should be designed into an adjustable; Or shall have the tensioning device.
