1. The sprocket teeth
In order to improve the running smoothness chain/reduce the dynamic load, the small sprocket teeth more as well. But small sprocket teeth also shoulds not be too much, or = I will be very big, so that the chain breaks due to skip the earlier.
Chain work after a period of time, wear make thinner/pin shaft sleeve and roller thinning, in under the action of tensile load F, the chain pitch of elongation. The chain pitch longer/chain sprocket season after heading addendum circle d.
Even number for general chain section to avoid using transition joints. In order 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.
2. The chain pitch
The chain pitch, the greater the theoretically the higher bearing capacity. But as mentioned in section: pitch, the greater the
