Rolling bearing lubricating method

Abstract

The invention belongs to the field of bearing lubrication, and particularly relates to a rolling bearing lubricating method. The provided method comprises the following steps that a), lubricating grease and a volatile organic solvent are mixed, and a lubricating grease solution is obtained; and b), a rolling bearing is immersed in the lubricating grease solution and taken out to be dried, and thena rolling bearing after lubrication is obtained. According to the provided method, the organic solvent is utilized for dissolving the lubricating grease, the lubricating grease makes contact with therolling face in an immersion manner, impurities are prevented from being guided in the conventional lubricating grease usage process, and the work performance of the bearing obtained after lubrication can be better guaranteed. For an ordinary non-sealing rolling bearing, in the lubricating method, lubricating grease injection is uniform, the usage amount is controllable, excessive usage and stacking of the lubricating grease are avoided, and pollution of lubricating grease volatilization to some components is reduced. For a sealing bearing, harm to the rolling bearing from a dismounting and mounting method and a heating method is avoided, and the rolling bearing lubricating method is suitable for filling of different kinds of lubricating grease at the low temperature, the normal temperature and the high temperature.

Description

technical field [0001] The invention belongs to the field of bearing lubrication, in particular to a rolling bearing lubrication method. Background technique [0002] Rolling bearings are one of the most commonly used kinematic pairs in mechanical mechanisms, and are widely used in both traditional and new mechanical structures. In order to ensure the normal operation of the shaft system, the rolling bearings must be well lubricated during use. At present, ordinary rolling bearings provided by the market have self-lubricating materials that can meet general applications, but for special environments with high or low temperatures, it is necessary to further add special grease. Although some foreign brands, such as NSK, can provide special high- and low-temperature bearings with special lubrication, their cost is often several times or even ten times that of domestic brands, and their lubrication schemes are commercial secrets that are not disclosed to the public. The model ...

Problems solved by technology

Fourth, apply a large amount of grease to the sealing gap of the bearing, and use the heating method to liquefy the grease and slowly penetrate into the sealing gap. This method is feasible for ordinary grease, but for occasions that need to add high-temperature grease , due to its adhesiveness at high temperatures, the heating temperature of the heating method must be higher than the applicable temperature range of the grease. For example, taking Kunlun HP-R grease as an example, its applicable temperature is as high as 200 ° C. If the heating method is used to lubricate the sealed bearing , it will inevitably cause the overall low-temperature tempering of the bearing, which will seriously affect the performance of the bearing and even cause it to be scrapped.
