Embodiment 1

[0031] Such as figure 1 and figure 2 , figure 1 It is a schematic flow chart of the quick assembly method of the angular contact bearing of the present invention, figure 2 It is a schematic diagram of bearing detection of the present invention, and the method includes the following steps:

[0032] S1: Install the first angular contact bearing face down on the detection boss.

[0033] Before installing the angular contact bearing, due to the manufacturing error of the angular contact bearing itself, first check the accuracy of the angular contact bearing itself. In a specific real-time scenario, the inner ring of the angular contact bearing is attached to the high-speed rotating planetary shaft, and the outer ring is close to the housing. The height of the inner ring of the angular contact bearing is deliberately designed to be higher than that of the outer ring of the angular contact bearing. The height of the bearing should be short so that the adjusting pad can be inst...

Abstract

The invention provides a rapid assembling method of an angular contact bearing. According to the rapid assembling method of the angular contact bearing, angular contact bearings are installed on a specific detection boss with the back faces being upward, wherein the inner ring width is equal to the width of the step of the detection boss; then, uniform axial pressure is exerted on the back faces of the angular contact bearings; and finally, the pressure is released, the height difference between the outer ring and the inner ring of each angular contact bearing is measured through the own weight of the outer ring, during assembling, the pretightening force is adjusted through adjusting pads, after the adjusting pads are additionally arranged, the height difference between the outer ring andthe inner ring of each bearing is kept within 0.02-0.035 mm. By the adoption of the rapid assembling method, the angular contact bearings are rapidly assembled, a test device is simple and convenientto operate, especially the adjusting pads are installed between the front faces of the inner rings and a planet carrier, so that the installation precision is convenient to adjust and control; the whole detection and assembling process is short in period and easy to operate, the universality is high, and the service life of each bearing is prolonged; and the rapid assembling method of the angularcontact bearing is particularly suitable for assembling the annular contact bearings in pair between a heavy-loaded planet carrier and a shell.

Description

technical field [0001] The invention relates to the field of bearing assembly, in particular to a quick assembly method for angular contact bearings. Background technique [0002] Bearings are an indispensable supporting device for mechanical equipment. In the field of mechanical transmission, bearings are used in almost all relative movements. Among them, angular contact bearings are widely used in high-speed and heavy-duty slewing pairs, and are generally installed in pairs on both sides of planetary gears. The main assembly methods are back-to-back assembly and face-to-face assembly. Appropriate preload is the key to ensure the normal operation of the bearing and maintain the normal life of the bearing. Too low and too high preload applied to the bearing will cause premature damage and failure of the bearing, thereby reducing the effective service life of the bearing. [0003] In the existing technology, it is mostly through strict control of the dimensional tolerance o...
