Problems solved by technology

During actual production, it was found that the existing processing methods are likely to cause inconsistencies between the inner and outer tooth orientations of the planetary gears, and directly processing a set of outer teeth at one time may easily cause a set of planetary gears to have tooth orientation errors, so that when the RV reducer is assembled It is more difficult for the eccentric shaft to match the planetary gear

Abstract

The invention discloses a phase alignment manufacturing tool clamp for internal and external teeth of a precision gear and a manufacturing method. The manufacturing tool clamp comprises a central positioning spindle and a directional tray, wherein the outer surface of the central positioning spindle is provided with teeth grooves; the directional tray is arranged on the central positioning spindlein a penetrating mode through a central hole arranged in the center of the directional tray; the phase of the external teeth of the directional tray is the same as the phase of the teeth grooves of the central positioning spindle; and planet teeth are clamped on the central positioning spindle and used for machining the tooth form of the planetary teeth. According to the clamp, the clamping is convenient, the error of a processing procedure can be ensured, the yield of product production is improved, and the matching difficulty of the planetary teeth during RV speed reducer assembly is reduced.

Description

technical field [0001] The invention relates to the technical field of precision gear manufacturing, in particular to a precision gear internal and external tooth pair phase manufacturing jig and a manufacturing method. Background technique [0002] RV transmission has two extremely strict technical indicators: the transmission error cannot exceed 1′; according to the model of the RV reducer, the backlash (Backlash) should not exceed 1′~1.5′. In addition, when operating under rated load, the total hysteresis including the hysteresis caused by elastic deformation cannot exceed 6'. In order to achieve the design accuracy, the processing and matching accuracy requirements of each part in the RV reducer are very high. Among them, the phase angle accuracy of the internal and external teeth of the planetary gear is particularly important. The high transmission error requirements of the RV reducer determine its internal 2~ The size error between the three matching planetary gears ...
