Sprocket drive is determined by the physical factors, between the roller and sleeve, sleeve and pin between the mating affect the mechanical transmission effect, when the inner and outer plate relative to the song when the sleeve can be around The pin is free to rotate. At work, the roller rolling along the sprocket teeth to reduce the wear of the tooth profile. The wear of the chain occurs mainly on the contact surface between the pin and the sleeve. Therefore, the inside and outside the link plate should be left a small gap, so that lubricants penetrate the pin and sleeve friction gap. Inside and outside the chain plate made of 8-shaped, is to make the chain of the various tensile strength similar to the tensile strength.
When the chain of sprockets can be used to form inertia, when the chain of the chain is even, the joints can be used inside and outside the link plate lap, and then use the cotter pin or spring clip lock. If the number of links is the base of the time, need to join a transition section to make it end to end, if the chain by the pressure of the transition chain will be bent, so try to use even chain.
Chain of the pitch is its main factor, when the pitch increases, the chain of the size of the various parts also want to increase accordingly, it can drive the power also increases, when the sprocket teeth of the same , The greater the pitch, the greater the diameter of the sprocket, in order to prevent the increase in the situation we can use the section of the multi-row or double-row chain, multi-row chain carrying capacity and the number of rows is proportional to the number of columns More, carrying capacity higher.
In the production or installation of the time to pay attention to the installation error, do not appear unequal or excessive number of cases appear, generally do not appear more than four of the situation, the early installation is also very important, we need to carefully school team installed sprocket or Whether the chain is correct, the overall installation and use is a learning, is the need for our long-term study and practice.
