End compensation rolling bearing with self-adaptive elimination of internal and external ring and ball clearance

Abstract

The invention discloses an end-compensated rolling bearing for self-adaptive elimination of inner and outer rings and ball clearance, which belongs to the technical field of bearings and includes a basic component, a limit component, and a clearance elimination component. A limit assembly is arranged inside the assembly, and a clearance elimination assembly is arranged on the side of the limit assembly. The present invention is scientific and reasonable, and safe and convenient to use. The present invention utilizes the high-frequency vibration of the bearing to propel it, and cooperates with the reset effect of the spring to make the folds The rubber expansion bladder keeps absorbing and extruding oil, so that the oil circuit keeps flowing at all times, and through the elastic swing of the heat dissipation vibrating tube, the surrounding air flow rate is accelerated, so that the oil flowing through the heat dissipation vibrating tube can be cooled efficiently, and the heat dissipation slots The high air flow rate inside can also improve the cooling effect of the bearing itself, which is beneficial to the maintenance of the bearing.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to an end compensation rolling bearing for self-adaptive elimination of clearance between inner and outer rings and balls. Background technique [0002] While supporting the transmission shaft, the bearing can also greatly reduce the friction resistance caused by the support, making the bearing an indispensable part of the transmission device. The bearing uses rolling friction or sliding friction to effectively reduce the friction of the inner and outer rings. The transmission stability and high efficiency of the transmission shaft play a vital role. Compared with sliding bearings, rolling bearings have less friction, but rolling bearings need to leave a gap between the balls and the ball grooves to ensure the freedom of ball rolling and avoid friction. The phenomenon of excessive force occurs, but as the service time of the bearing increases, under the action of friction and vibra...

[0002] While supporting the transmission shaft, the bearing can also greatly reduce the friction resistance caused by the support, making the bearing an indispensable part of the transmission device. The bearing uses rolling friction or sliding friction to effectively reduce the friction of the inner and outer rings. The transmission stability and high efficiency of the transmission shaft play a vital role. Compared with sliding bearings, rolling bearings have less friction, but rolling bearings need to leave a gap between the balls and the ball grooves to ensure the freedom of ball rolling and avoid friction. The phenomenon of excessive force occurs, but as the service time of the bearing increases, under the action of friction and vibration, the temperature of the inner and outer rings of the bearing rises, resulting in thermal expansion. At this time, the gap between the bearing ball and the ball groove will be larger. It is greatly reduced, which has a serious impact on the efficient use of the bearing, and the existing bearings cannot control the stability of the gap between the ball and the ball groove in real time according to the bearing temperature, so people need end compensation for the adaptive elimination of the inner and outer rings and the ball clearance Rolling bearings to solve the above problems
