specific Embodiment approach 1

[0020] Specific implementation mode one: the bearing ring cleaning method of this implementation mode is carried out according to the following steps:

[0021] Step 1. Ultrasonic cleaning of the bearing ring with a dehydrating hydrocarbon cleaning agent;

[0022] Step 2, using a dehydrating hydrocarbon cleaning agent to dehydrate and clean the bearing ring after step 1 cleaning;

[0023] Step 3, using a hydrocarbon cleaning agent to perform a degassing ultrasonic cleaning on the bearing ring after step 2 cleaning;

[0024] Step 4, using a hydrocarbon cleaning agent to perform secondary degassing and ultrasonic cleaning on the bearing ring after step 3 cleaning;

[0025] Step 5, recovering the dehydrated hydrocarbon cleaning agent and the hydrocarbon cleaning agent used in the cleaning of steps 1 to 4;

[0026] Step 6, the bearing ring is cooled, and it is completed.

[0027] This embodiment has the following beneficial effects:

[0028] 1. In this embodiment, dehydrated hy...

Abstract

The invention relates to a bearing ring cleaning method, in particular to a bearing ring cleaning method. The problems that the cleaning quality is poor and potential safety hazards exist when bearings and parts are cleaned with 180 # aviation washing gasoline are solved. The method comprises the following steps: carrying out ultrasonic cleaning and dehydration cleaning on the bearing ring by adopting a dehydrated hydrocarbon cleaning agent, then carrying out primary degassing ultrasonic cleaning and secondary degassing ultrasonic cleaning by adopting a hydrocarbon cleaning agent, recovering the dehydrated hydrocarbon cleaning agent and the hydrocarbon cleaning agent, and cooling the bearing ring. According to the invention, a dehydrated hydrocarbon cleaning agent and a hydrocarbon cleaning agent are adopted for cleaning, so that the cleaning requirement of ferrule parts before submission is met, and the cleaning performance is equivalent to or higher than that of 180 # aviation washing gasoline. The cleaning quality is high, no harm is caused to human bodies, and safe production is guaranteed. The bearing ring cleaning device is suitable for bearing ring cleaning.

Description

technical field [0001] The invention relates to a method for cleaning a bearing ring. Background technique [0002] In order to improve the cleanliness control ability of aero-engines, the cleanliness level control requirements of bearings are the most stringent. At present, there is a certain gap between the actual cleanliness level and the cleanliness level control requirements of bearings. It is very important to carry out cleanliness control of bearings and parts. At present, 180# aviation washing gasoline is one of the earliest and most traditional cleaning agents. It has the advantages of wide cleaning range, good effect, and low price, but it also has a fatal weakness. The main problem with its use is that transportation and storage are also extremely dangerous, and it is not suitable for cleaning machines and ultrasonic cleaning. Gasoline cleaning has been banned in foreign countries, and it is also being phased out in my country. [0003] The national gasoline repla...
