| Abstract: | Taking various original errors in the cam mechanism as random variables, we analyzed the shape error of cam and roller, the clearance of hinged joint and removal pair, the quantity of abrasion, the eccentricity of cam and roller, and size error of cam setover circle. According to the principle of linear pile up of small displacement, the reliability model of cam mechanism kinematic accuracy is built. The reliability of the mechanism output kinematic accuracy is analyzed and calculated, and some important conclusions are obtained. |
