Chain sprocket tooth profile must ensure that the energy saving mesh smooth entry and exit freely, minimize the impact of the meshing of link and contact stress, and is easy to be processed. It is made up of three sections of circular arc and a straight line, referred to as "three arc - straight tooth. Sprocket tooth profile using a standard cutting tool processing, work in don't have to draw end tooth shape on the graph, only need to indicate on the diagram "tooth profile according to provisions of 3 rgb1244-85", but should draw the axial plane of sprocket tooth.

Small diameter sprocket made of monolithic, medium diameter of sprocket to make radial plate more, for ease of handling, loading and weight loss, on the radial plate hole, large diameter combined sprocket can make it, the ring gear and the wheel core is available in different materials such as C45, stainless steel and other materials.

Malleable cast iron and cast steel sprocket materials should guarantee the tooth has enough strength and abrasion resistance, so the sprocket tooth surface is generally after heat treatment, to a certain hardness.

1, new sprocket is too long, or elongation after use, it is difficult to adjust, can see things down link, but must be even. Link from the sprocket back through the lock plate inserted in the outside, lock the opening of the piece should be toward the rotation in the opposite direction.

2, sprocket in the work should be timely filling lubricating oil. Lubricating oil must be into the roller and the inner sleeve fit clearance, to improve working conditions, reduce wear and tear.

3, on the old sprocket cannot be used mixed with part of the new sprocket, otherwise easy to impact in the transmission, snap sprocket.

4, machine long stored, sprocket should be removed with kerosene or diesel clean, then coated with oil or butter in a dry place.
