Repair process for bearing base shaft hole

Abstract

The invention discloses a repair process for a bearing base shaft hole. The repair process is characterized by comprising the following requirements that 1, the abrasion depth of the shaft hole is detected, and if the abrasion depth is smaller than 4 mm in the diameter direction, to-be-repaired parts are polished and deepened through an electric tool; 2, the to-be-repaired surface of a bearing hole is cleaned through a cleaning agent, and an outer ring of a bearing is sprayed with a layer of a release agent so that disassembling of the bearing can be facilitated; 3, the bearing is positioned, and a shaft and the bearing are assembled together with glue; and 4, the back half portion of the outer ring of the bearing is coated with a repairing agent, the coating amount should ensure that the position between the outer ring of the bearing and the shaft hole cannot lack the glue, the bearing coated with the repairing agent is pushed into the shaft hole and cured for 8-16 hours at the temperature of 30 DEG C-50 DEG C, corners are trimmed through abrasive cloth or a file, and the bearing base shaft hole can be used after being completely cured. The repair process for the bearing base shaft hole is reasonable in process, low in cost, reasonable and coordinated in parameter collocation, short in time and easy to operate.

Description

technical field [0001] The invention relates to a repairing process for a shaft hole of a bearing seat. Background technique [0002] Bearing jamming can lead to damage to the bearing seat, and the alternating load will cause the bearing seat to wear into an oval shape. If it is not repaired in time, it will inevitably lead to excessive vibration and a series of mechanical damage. However, the existing repair plan for the shaft hole of the bearing seat does not Its process arrangement is unreasonable, the process is numerous, and the time is long, which can no longer meet the requirements and needs to be improved to improve performance. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a repair process for the shaft hole of the bearing seat with reasonable process, simple operation, short time and low manufacturing cost. [0004] In order to achieve the abov...
