Structure design of the Sprocket wheel

The Sprocket wheel tooth

Sprocket wheel tooth shape chain must ensure that 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 wheel end tooth profile. It consists of three sections of circular arc aa, ab, CDS and a straight line BC, referred to as "three arc - straight tooth. Tooth shape with a standard cutting tool processing, the Sprocket wheel work 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 Sprocket wheel shaft surface tooth shape, its size refer to the design manual.

Sprocket wheel structure

The commonly used Sprocket wheel structure. Small diameter Sprocket wheel made of monolithic, medium diameter of Sprocket wheel made of spoke plate more, for ease of handling, loading and weight loss, on the radial plate hole, large diameter Sprocket wheel can be made into modular, 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 wheel material

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