Problems solved by technology

[0005] The existing outer ring adopts the cutting process. The dimensional accuracy of the processed groove is low, the roughness is poor, and there are obvious processed ridges in the groove. When friction occurs with the roller, the roller and the groove Both are easy to wear and tear, resulting in a short service life of the product, and are prone to abnormal noise
At the same time, the dimensional accuracy is very controlled, the wire speed is extremely slow, and the processing efficiency is low

Abstract

The invention discloses a processing process method for an outer ring which adopts a 20Cr material. The processing process method is characterized by comprising the following steps: S10, forging to obtain blank; S2, roughly turning an outer circle, a first end surface, a second end surface and an inner hole in sequence; S30, broaching grooves; S40, extruding the grooves; S50, cleaning cuttings andgreasy dirt on the surface of a part; S60, finely turning the inner hole, the first end surface, the outer circle, a settling table, a tool withdrawal groove and a second end surface in sequence, wherein machining allowance is required to leave for the diameter and the depth of the settling table; S70, inspecting a dimension; S80, filing and extruding mouth edges of the grooves to remove burrs; S90, drilling; S100, performing thermal treatment; S110, performing thermal treatment inspection; S120, performing shot blasting; S130, finely turning the settling table; S140, cleaning and preventingrust; and S150, inspecting and warehousing. The processing process method can be used for outer ring manufacturing and processing, and can be used for solving the technical problem that a short service life and abnormal sound are easily caused by insufficient roughness and precision of grooves of the outer ring.

Description

technical field [0001] The invention belongs to a processing method for an outer ring. Background technique [0002] The principle of the starting one-way clutch is one-way engagement and reverse disengagement. When starting, the starter motor (or starter motor, etc.) is generally used to drive the crankshaft to rotate through the one-way clutch. Since the speed of the starter motor is higher than that of the engine (the engine is relatively static or the speed is very low before starting), when the engine starts Finally, because its speed is higher than that of the starter motor, the one-way clutch rotates in the opposite direction relative to the crankshaft, so the starter motor is separated from the rotation of the engine to protect the starter motor from damage. [0003] And start the outer ring of one-way clutch (can refer to publication number CN209041377U), in order to improve the performance of this outer ring, this outer ring uses instead Figure 1-3 in the structu...
