A kind of assembly method of bearing, shaft sleeve and air expansion shaft

Abstract

The invention discloses a method for assembling a bearing, a shaft sleeve and an air-expanding shaft. The second bearing is loaded; the second bearing is transferred; the second bearing is press-fitted; the positioning and conveying device used in the feeding and positioning process of the air-expansion shaft is set to a circular shape and operates intermittently between the above steps. The positioning and conveying device is annularly provided with a plurality of workstations for vertical positioning of the inflatable shaft. It realizes the mechanized assembly of bearings, bushings and inflatable shafts, with strong work continuity, high work efficiency, and guaranteed assembly accuracy; avoids the problem of damage caused by manual assembly; reduces the labor intensity of the staff and reduces the amount of labor. , the labor cost is low.

Description

technical field [0001] The invention belongs to the technical field of assembly of rotating components, and in particular relates to an assembly method of a bearing, a shaft sleeve and an air expansion shaft. Background technique [0002] The inflatable shaft is a support for carrying raw materials and providing rotating work, and the rotation of the inflatable shaft can only be achieved by relying on the transition of the rotating assembly (the rotating assembly includes: a shaft sleeve and at least two bearings, the bearings are arranged on the shaft sleeve. and the inflatable shaft, the bearing and the bushing are installed on the main body of the equipment). At this stage, the assembly method for the inflatable shaft and the bearing is as follows: the staff first places a bearing on the inflatable shaft, and then uses a pressure applicator to put the The bearing is assembled to the inflatable shaft, and then, the worker transfers the shaft sleeve, and then uses a pressur...

AI Technical Summary

Problems solved by technology

[0003] 1. The labor intensity of the staff is high, the labor volume is large, and the labor cost is high;

[0004] 2. Low work efficiency;

[0005] 3. Bearings and bushings need to be pressed by different pressure-applying devices, so during the pressing process of bearings and bushings, it is necessary to transfer between different pressure-applying devices, which will also affect work efficiency;

[0006] 4. Assembly accuracy cannot be well guaranteed;

[0007] 5. During assembly, if the position accuracy of bearings and bushings is poor, there will be problems of damage to bearings, bushings and air shafts
