Bearing vibration-reducing chemical milling agent and method for using same

Abstract

A vibration-reducing chemical lapping agent for bearings essentially comprises abrasive, surface active agent, anti-rust additive and substrate medium, wherein, the abrasive is 30-60%, the surface active agent is 2-5%, the anti-rust additive is 3-5%, and the substrate medium is mineral oil and accounts for 30-65%. The materials in above proportions are mixed fully, injected evenly on a frictional surface of a bearing to be processed, lapped at 900-1500 r / min for 2-5 minutes, ultrasonically washed by detergent, or washed by cleaning gasoline when the lapping agent is of low amount. The chemical lapping agent is to carry out chemical erosion and mechanical grinding by using the physical and chemical properties of the material, and join in an organic way the specialty of nanometer material, so as to improve the surface shape, and reduce vibration and noise on the frictional surfaces of bearings. The invention can effectively reduce vibration 2-8 dB in bearings.

Description

(1) Technical field: [0001] The invention belongs to the field of bearing processing, and relates to a chemical abrasive for reducing the vibration value of a bearing and a using method thereof. (two) background technology: [0002] In the field of bearing processing in our country, the quality of the processing quality of the bearing friction pair determines whether the vibration value of the bearing can meet the standard. At present, there are still some bearing manufacturers in our country, especially some small and medium-sized bearing manufacturers, whose bearing vibration value compliance rate is low. The main reason is that the surface morphology of the bearing raceway is relatively rough. Since the bearing has been assembled into a finished product, it is no longer possible to grind individual parts, resulting in downgraded sales or scrapping of the product. The superfinishing bearing grinding machine in the prior art can only grind a single part in the bearing, and...

The main reason is that the surface morphology of the bearing raceway is relatively rough. Since the bearing has been assembled into a finished product, it is no longer possible to grind individual parts, resulting in downgraded sales or scrapping of the product

The superfinishing bearing grinding machine in the prior art can only grind a single part in the bearing, and because the precision of the grinding machine itself and the grain size of the grinding wheel have certain limitations, that is to say, the surface processing precision is not enough, so that the processing The bearing quality is not ideal
