Anti-rotation positioning structure for shaft

Abstract

The invention discloses an anti-rotation positioning structure for a shaft. The anti-rotation positioning structure comprises a connecting shaft, a connecting sleeve is integrally welded to one end of the connecting shaft, an inner adjusting sleeve is connected to the middle of the inner wall of the connecting sleeve through threads, spline grooves are formed in the outer wall of the end, close to the connecting sleeve, of the connecting shaft at equal intervals, inner linear spline teeth are clamped to the inner walls of the spline grooves, the outer wall of the side, close to the connecting sleeve, of the connecting shaft is connected with a clamping sleeve in a clamped mode, and the clamping sleeve is matched with the end of the inner linear spline teeth in a clamped mode. The inner linear spline teeth are annularly distributed on the outer wall of the connecting shaft at equal intervals, a concave-convex spline groove body is formed between the inner linear spline teeth and the outer wall of the connecting shaft to limit relative sliding between the shaft and a shaft sleeve, limiting teeth are arranged at the one-third position of the inner linear spline teeth, the limiting teeth limit relative sliding between the shaft sleeve and the shaft in the axial direction, an inner penetrating rod extrudes to enable a pressing rod and the inner side of the inner linear spline teeth to be mutually clamped, and it is guaranteed that the whole inner linear spline teeth are clamped in the groove body.

Description

technical field [0001] The invention relates to the technical field of shaft accessories, in particular to an anti-rotation positioning structure for a shaft. Background technique [0002] The shaft (shaft) is a cylindrical object that goes through the middle of the bearing or the middle of the wheel or the middle of the gear, but there are also a few of them that are square. A shaft is a mechanical part that supports and revolves with a rotating part to transmit motion, torque or bending moment. Generally, it is in the shape of a metal round rod, and each segment can have different diameters. The parts that make rotary motion in the machine are mounted on the shaft. [0003] Many existing shafts are rigidly plugged and fitted. After plugging and fitting between the bushing and the shaft, under high-strength torque, it will cause sliding between the bushing and the shaft as a whole, which will cause the overall shaft to be fixed unstable, or The connection between the sha...

Problems solved by technology

[0003] Many existing shafts are rigidly plugged and fitted. After plugging and fitting between the bushing and the shaft, under high-strength torque, it will cause sliding between the bushing and the shaft as a whole, which will cause the overall shaft to be fixed unstable, or The connection relationship between the shaft and the sleeve is unstable
