In order to maintain the original performance of the imported bearings in good condition for as long as possible, maintenance, overhaul, and accident prevention are required to ensure the reliability of operation and improve productivity and economy. Maintenance is best carried out on a regular basis in accordance with the operating standards for the mechanical operating conditions. The content includes monitoring of operating conditions, replenishment or replacement of lubricants, and periodic disassembly inspections. As a maintenance item during operation, there are bearing rotation sound, vibration, temperature, lubricant state, and the like.
Cleaning of the bearing: When disassembling the imported bearing for inspection, first record the appearance of the bearing, confirm the residual amount of the lubricant, and then wash the bearing after sampling the lubricant for inspection. As a cleaning agent, gasoline and kerosene are commonly used.
The cleaning of the removed bearings is divided into coarse cleaning and fine cleaning. They are placed in the container respectively, and the metal mesh bottom is placed first so that the bearing does not directly contact the container. In rough cleaning, if the bearing is rotated with dirt, it will damage the rolling surface of the bearing and should be noted. In the rough cleaning oil, use a brush to remove the grease and the adhesive. After it is almost clean, it is transferred to the fine wash.
Fine washing is to carefully clean the bearing while rotating it in the cleaning oil. In addition, the cleaning oil should always be kept clean.
When the bearing is in operation, due to the influence of external or internal causes, the original matching gap is changed, the precision is lowered, and even the "biting death" is called the gap change failure. External causes such as excessive interference, inadequate installation, expansion caused by temperature rise, instantaneous overload, etc., internal causes such as residual austenite and residual stress are unstable, which are the main reasons for the failure of the clearance change.
Imported bearings are mass-produced mechanical parts, and the manufacturing precision is very strict, and the degree of specialization in technology is very high. Therefore, for most of the easily available bearing types, it should be more cost-effective to buy than in the following cases. Next, consider the bearing repair problem:
(1) A large number of bearings of the same type used in large factories are mainly in the form of wear on the rolling surface, fatigue or fretting abrasion, especially the damaged parts are mostly cages or rolling elements, and the ferrules or gaskets are still repaired. value;
(2) Large and extra large bearings, which have no major damage to the parts due to failure or failure, or valuable bearings must be managed to extend their useful life;
(3) Some types of bearings that are really difficult to purchase, have no spare parts after failure and have to be repaired, especially imported bearings;
