Check ring for shaft and machining method of check ring for shaft

Abstract

The invention discloses a machining method of a check ring for a shaft. The machining method includes the following steps: carrying out blanking processing on a metal board to obtain a circle, forming a base body of the check ring for the shaft, increasing the size allowance of the inner circle in the blanking process design, carrying out machining to remove the size allowance of the inner circle to enable the surface of the inner circle to be smooth and free of a taper, and carrying out cutting to enable the check ring to be provided with an opening. The invention provides the check ring for the shaft, wherein the check ring for the shaft is machined through the machining method. The check ring for the shaft comprises the annular base body and a center hole, the base body has the predetermined thickness, is provided with the opening and is defined by two annular planes, an inner lateral side and an outer lateral side, and the opening is formed between the two annular planes. According to the machining method of the check ring for the shaft and the check ring for the shaft, the size allowance of the inner circle of the check ring for the shaft is increased, the inner circle of the check ring for the shaft is machined in a machining mode to obtain the check ring for the shaft, the inner lateral side of the check ring is smooth and free of the taper, and in the assembly process and the use process, when being stressed, the check ring is large in contact area, even in stress and not prone to jumping out.

Description

technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a retaining ring for a shaft and a processing method thereof. Background technique [0002] In the prior art, the shaft retaining ring with the structure of an open ring is a commonly used mechanical part, and it has a standardized design standard. Its main function is to fasten the ring-shaped parts on the shaft, which can prevent the The movement of other parts belongs to a kind of fastener. In actual production, shaft retaining rings produced according to the national standard may pop out during assembly and use. This is mainly due to the relatively large tolerance of the outer diameter of the shaft retaining ring in the national standard, and the existence Large and small arc surfaces, and the inner circle has an obvious taper, resulting in too small contact area when the shaft retaining ring is stressed, and the shaft retaining ring jumps out after being stressed. ...
