Embodiment Construction

[0013] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0014] like figure 1 The shown linear ball guide bushing includes a rotating shaft 1 and a bearing sleeve set outside the rotating shaft 1. The bearing sleeve includes a cage 3 and a bearing sleeve shell 2, and balls are arranged between the cage 3 and the bearing sleeve shell 2. 4. There are stop rings 5 ​​at both ends of the bearing sleeve, pin holes 6 are provided outside the bearing sleeve shell 2, and pins are inserted into the pin holes 6 to connect the cage 3 and the bearing sleeve shell 2; Arc rolling channel 8.

[0015] The bearing housing shell 2 is provided with an oil filling hole 7 for injecting lubricating oil; the cag...

Abstract

The invention relates to the technical field of linear guide rail accessories, in particular to a linear ball guide sleeve which is widely applied to sliding parts of a lathe, a grinder and other mechanical devices. The linear ball guide sleeve comprises a rotating shaft and a bearing sleeve, wherein the outside of the rotating shaft is sleeved with the bearing sleeve. The bearing sleeve comprises a holding frame and a bearing sleeve shell. Balls are arranged between the holding frame and the bearing sleeve shell. Stop rings are arranged at the two ends of the bearing sleeve. A pin hole is formed in the outside of the bearing sleeve shell. A pin is inserted into the pin hole to connect the holding frame with the bearing sleeve shell. The rotating shaft is provided with a plurality of circular arc-shaped rolling channels. According to the linear ball guide sleeve, the design is reasonable; the rotating shaft is provided with the multiple circular arc-shaped rolling channels so that the rated load can be improved; an oil injection hole is formed so that the lubrication performance of the linear ball guide sleeve can be improved; the abrasion resistance of the linear ball guide sleeve is improved and the service life is prolonged; the stop rings are arranged at the two ends of the bearing sleeve, and thus the linear ball guide sleeve has the advantage of dust prevention.

Description

technical field [0001] The invention relates to the technical field of linear guide rail accessories, in particular to a linear ball guide bush widely used in sliding parts of mechanical equipment such as lathes and grinders. Background technique [0002] Linear guides are widely used in various industrial equipment and precision instruments. As an important part, the precision and wear resistance of linear ball guide bushes have been greatly improved. However, the traditional linear ball guide bush has complex structure, cumbersome installation and maintenance, low precision and stable performance, poor wear resistance and poor lubrication performance, and requires frequent maintenance or replacement. And it will generate heat, the service life will be shortened, the production efficiency will be reduced, and the production cost will be increased. Therefore, a new technical solution is needed to solve the above problems. Contents of the invention [0003] The technical ...
