Abstract

The invention belongs to the technical field of material friction and lubrication, and particularly relates to a nanometer grinding agent capable of reducing gear vibration, a gear surface grinding agent, and preparation and application thereof. The nanometer grinding agent capable of reducing gear vibration is prepared from nanometer stage titanium dioxide, zirconium oxide, aluminum nitride, elemental copper, cerous fluoride, molybdenum disulfide and lead oxide. The invention also provides the gear surface grinding agent containing the nanometer grinding agent. The gear surface grinding agentcan reduce the starting abrasion of a friction pair and hard friction in the boundary lubrication state, and can also perform mechanical restoration and polishing on concave pits or bulges on the gear engaging surface, so that the surface of the friction pair such as a gear can be smoother; the surface microstructure of the gear friction pair can be effectively improved in a short time; the flatness degree of the transmission pair contact surface can be improved; the gear vibration can be effectively reduced; the goals of transmission vibration reduction and more stable operation can be achieved; the grinding agent is applicable to the surface microdefect correction of most metal abrasion pairs; the vibration of machinery due to surface micro appearance defects of movement pairs can be reduced.

Description

technical field [0001] The invention belongs to the technical field of material friction and lubrication, and specifically relates to a nano abrasive that can reduce gear vibration, a tooth surface abrasive, and its preparation and application. Background technique [0002] In the development of industry at home and abroad, vibration is one of the important factors affecting the service life of machinery. Due to the limited precision of mechanical processing and manufacturing, the high-precision, low-vibration transmission gears produced by many gear factories have a low compliance rate. In addition, errors caused by gear assembly, debugging, and running-in cannot be absolutely avoided, resulting in tooth surfaces in the gear transmission process. Severe wear and tear, severe vibration and noise. The effect of improving the vibration during the gear transmission process by performing high-precision grinding and modifying methods on a single gear in the later stage is limite...
