Description

Heavy-duty bearing mechanism with liquid lubrication Technical Field The utility model relates to the technical field of bearings, in particular to a liquid lubrication heavy-duty bearing mechanism. Background A bearing is a mechanical part for supporting a rotating shaft or other moving part and plays a vital role in a mechanical transmission system. The friction in the motion process can be reduced, the rotation precision of the shaft is ensured, and the operation efficiency and the service life of the equipment are improved. In industrial production and mechanical equipment operation, a large number of working conditions need to bear huge load, and the common bearing is difficult to meet the requirements, so that a heavy-duty bearing is generated, and the heavy-duty bearing can bear high load and high torque, and ensures that the equipment stably operates under severe conditions. In order to reduce the coefficient of friction and reduce wear, it is desirable to use a liquid lubricated heavy duty bearing mechanism. In the prior art, when the bearing runs under high load for a long time, the contact area of the ball and the inner and outer ring raceways is easy to generate local stress concentration, so that the bearing is worn out prematurely and fatigued inely, thereby influencing the heavy load of the bearing. Disclosure of utility model In order to overcome the defects, the utility model provides a liquid lubrication heavy-duty bearing mechanism, which aims to solve the problem that local stress concentration is easy to occur in the contact area of balls and inner and outer ring raceways when the bearing runs under high load for a long time.
