Problems solved by technology

However, the lubricant is easily shifted from the rectangular cross section to the outside of the groove due to the rotation of the shaft
This causes the lubricant to be lost too quickly, which limits the rotation speed of the shaft to a certain extent and reduces labor efficiency

Embodiment

[0027] A method for processing a trapezoidal cross-section groove 2 on the outer wall of a shaft sleeve 1, characterized in the following steps:

[0028] (1) Cut out several rectangular slots 2 on the outer wall of the bushing 1 by using a milling cutter;

[0029] (2) Heat and expand the temporary outer bushing which is the same as the outer diameter of the bushing 1 to be larger than the outer diameter of the bushing 1;

[0030] (3) Cut out the outer wall of the rectangular groove 2 from the shaft sleeve 1 and heat it to make it into a molten state;

[0031] (4) Put the shaft sleeve 1 into the temporary inner shaft with the same hole diameter as the shaft sleeve 1;

[0032] (5) After putting the sleeve 1 into the heated temporary outer sleeve, quickly cool the temporary outer sleeve;

[0033] (6) Quickly reheat and expand the temporary outer bushing and bushing 1, and remove the temporary outer bushing and temporary inner shaft;

[0034] (7) Remove the outer wall of the sh...

Abstract

The invention relates to the field of shaft sleeve processing, in particular to a processing method of a shaft sleeve outer wall cutting groove. The cross section of the cutting groove is designed into the mode that the lower bottom of the cutting groove is located in a groove, through the effect of an inclined edge of the trapezoid cutting groove, lubricant can flow toward the bottom of the cutting groove under rotation and driving of a shaft, the loss of the lubricant is reduced, and the labor efficiency is improved.

Description

technical field [0001] The invention relates to the field of shaft sleeve processing, in particular to a processing method for cutting grooves on the outer wall of a shaft sleeve. Background technique [0002] In the processing of the shaft sleeve, in order to make the shaft sleeve have good lubricating performance, slots are usually cut out on the outer wall of the shaft sleeve as oil passages for lubricating oil or graphite grooves, or flow parts of other lubricants. For the convenience of processing, the cross section of the groove is mostly rectangular. However, the lubricant is easily displaced from the rectangular cross-section to the outside of the groove by the rotation of the shaft. This causes the lubricant to be consumed too quickly, which limits the rotation speed of the shaft to a certain extent and reduces labor efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention provides a processing method for cutting...
