Gauge for distance from sharp groove on shaft to end surface of shaft and processing method as well as test method thereof

Abstract

The invention belongs to a machining technology, provides a gauge for a distance from a sharp groove on a shaft to the end surface of the shaft and a processing method as well as a test method thereofand solves the problems that measurement is difficult and measured data is inaccurate in an existing method adopted for detection of a position of a sharp circular arc groove. The gauge comprises a ring-shaped first body as well as two detection slips which are located above the ring-shaped first body and arranged in an axial symmetry manner; and the ring-shaped first body and the two detection slips are processed according to the following steps: 1) processing the ring-shaped first body and a ring-shaped second body; enabling the upper edge of the ring-shaped second body to be contracted inwards to form a sharp-blade-shaped convex ring, wherein the inner diameter D1 of the ring-shaped first body, the inner diameter D2 of the ring-shaped second body, the inner diameter D3 of the sharp-blade-shaped convex ring and the outer diameter D0 of a detected shaft part satisfy a relationship that D0<D3<D1<D2; 2) processing a through slot in the radial direction in the upper edge of the ring-shaped second body, thus forming two tile structures in axial symmetry; and 3) respectively processing the upper end surfaces of the two tile structures, thus forming two detection slips.

Description

technical field [0001] The invention belongs to mechanical processing technology, and in particular relates to a checking tool for the distance from a sharp groove on a shaft to an end face of the shaft, a processing method and a testing method thereof. Background technique [0002] The gearbox is set on the power bogie at the bottom of the vehicle and installed on the axle of the vehicle. When the vehicle is running, the gearbox directly bears the impact of the rail on the wheel set. The gearbox is a key component of the vehicle, and its reliability directly affects safe operation of the vehicle. Auxiliary box drive gear is one of the main components of the linkage between the main box and the auxiliary box of the gearbox, and is a necessary part to realize power transmission. Therefore, the performance of the auxiliary box drive gear directly affects the driving state of the vehicle. [0003] An auxiliary case drive gear adopts an axial structure, such as figure 1 with ...
