Is a kind of button with embedded tooth chain sprocket gear wheels, with section to link or cable pitch accurate block mesh. Sprocket is widely used in chemical industry, textile machinery, escalators, wood processing, parking equipment, agricultural machinery, food processing, instrument, such as oil industry of mechanical transmission, etc.

Sprocket tooth profile

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. Commonly used sprocket end tooth shape as shown in figure 1. It consists of three sections of circular arc aa, ab, CDS and a straight line BC, 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, its dimensions refer to the design manual.

Sprocket structure

Four kinds of common structure of sprocket. 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, at this moment, in different material ring gear and the wheel core is available. The C45, for example, the material such as stainless steel.

Sprocket material

Sprocket should guarantee the tooth have enough strength and abrasion resistance, so the sprocket tooth surface is generally after heat treatment, to a certain hardness.
