End compensation rolling bearing capable of adaptively eliminating clearances between inner and outer rings and balls

Abstract

The invention discloses an end compensation rolling bearing capable of adaptively eliminating clearances between inner and outer rings and balls, and belongs to the technical field of bearings. The end compensation rolling bearing comprises a basic assembly, a limiting assembly and a clearance eliminating assembly, the basic assembly is located on the outermost side of the whole device, the limiting assembly is arranged in the basic assembly, and the clearance eliminating assembly is arranged on the side of the limiting assembly. The end compensation rolling bearing is scientific, reasonable and safe and convenient to use, a corrugated rubber expansion bag is made to do oil suction and extrusion movement all the time through the high-frequency vibration pushing effect of the bearing and the reset effect of a spring in cooperation, an oil way is kept in the flowing state all the time, the surrounding air flow speed is increased through elastic swing of a heat dissipation vibration pipe, oil flowing through the heat dissipation vibration pipe can be efficiently cooled, the cooling effect of the bearing can be improved through the high air flow speed in heat dissipation groove holes, and maintenance of the bearing is facilitated.

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
