Title: Grooved clutch plate of differential limitting-device
Inventor: FUJIWARA KIROKU
IPC: F16H48/38
Filed: 1986-08-07
Abstract: PURPOSE:To enhance the oil film forming state on a sliding friction surface and reduce noise by forming the grooved clutch plate of a differential limitting- device for a car by rolling it with rolls having many projected lines on their outer periphery and by flattening both faces of the same with smoothing rolls. CONSTITUTION:At least one of two sliding friction surfaces of a grooved plate is formed by pushing the projected line sections 10 and 30 of rolls 1 and 3 thereinto forming grid shaped oil retaining grooves with the distance between the grooves becoming short gradually as the projecting line sections are pushed into the surface deeperly. The marginal section of the opening of the oil retaining grooves are formed by circular arc sections having specified curvature, and the sliding friction surface is applied flattening rolling treatment with smoothing rolls 4. Therefore, since protruding sections are not produced on the front face section in the opening sides of the oil retaining grooves, chattering sound is effectively regulated. In this case, groove width L must be about 0.2-1.5mm, the groove width in the side of the bottom faces of the grooves must be about 0.2-1mm, the curvature R of a circular arc section must be 0.03-0.1, the depth (h) of the grooves must be about 0.08-0.5mm, and the distance U between grooves must be about 1.0-10mm.
