T/WLJC 15-2018 Arc camber mechanism design specifications

Scope

Scope: This standard specifies the basic principles, typical processes, and main methods for the design of cam mechanisms with curved surfaces. This standard applies to cam mechanisms with curved surfaces used in high-speed, backlash-free transmission devices. Main technical content: Cam mechanisms with curved surfaces refer to those in which the base of the active cam is a circular arc rotating body, and the cam profile is made into a convex ridge. Through the change of the helical angle of the working surface, the intermittent movement and positioning of the indexing plate are achieved. On the driven turntable, rollers are evenly distributed along the circumference of the indexing plate. During the development of this standard, the experience gained from the research and development of the national major science and technology project "Disk Tool Magazine with Automatic Tool Changing Device" was summarized. The standard mainly specifies the calculation formulas for the basic parameters of cam mechanisms with curved surfaces, the analysis methods for pressure angles and the curvature of the working surface, the design steps of cam mechanisms with curved surfaces, the design criteria for cam curves, and the principles for selecting cam materials. Cam mechanisms with curved surfaces designed according to this standard have been used in the products of the national major science and technology project "Disk Tool Magazine with Automatic Tool Changing Device", and it has been verified that they are technically mature.
