Embodiment Construction

[0024] The present invention provides a rolling bearing, which includes an inner ring 1, an outer ring 2 and a cage 3. The cage 3 is provided with several pockets 31 for accommodating rollers. body 32, the inner wall of the pocket hole 31 is provided with a slot 311, the slot 311 is provided with a movable block 312, one end of the movable block 312 is fixedly connected with the inner wall of the slot 311, and the other end is provided with a grease scraping cotton 4. The movable block 312 is made of a shape memory alloy, the movable block 312 has a first shape at a first temperature, and the movable block 312 has a second shape at a second temperature, and the movable block 312 has a second shape at a second temperature. Stretching in the first form makes the grease scraping cotton 4 expose the slot 311 and contacts the inner roller of the pocket hole 31, and the movable block 312 shrinks in the second shape so that the grease scraping cotton 4 retracts into the slot 311, and ...

Abstract

The invention discloses a new type of rolling bearing, which includes an inner ring, an outer ring and a cage. The cage is provided with several pockets for accommodating rollers. The pockets are connected by beams. It is characterized in that: a slot is opened on the inner wall of the pocket hole, a movable block is arranged in the slot, one end of the movable block is fixedly connected with the inner wall of the slot, and grease scraping cotton is arranged at the other end, and the movable block has a shape Made of memory alloy, the movable block has a first form at a first temperature, and the movable block has a second form at a second temperature, and the movable block is stretched in the first form so that the grease scraping cotton is exposed to the slot In contact with the inner roller of the pocket, the movable block shrinks in the second form so that the grease scraping cotton retracts into the groove. Avoid excessive grease in the bearing to cause grease throwing and grease leakage inside the bearing, and further ensure that the service life of the bearing will not be reduced due to grease loss.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a rolling bearing. Background technique [0002] Rolling bearing is a precision mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling body and cage. The function of the inner ring is to cooperate with the shaft and rotate together with the shaft; the function of the outer ring is to cooperate with the bearing seat to play a supporting role; Because the cage evenly distributes the rolling elements between the inner ring and the outer ring, its shape, size and quantity directly affect the performance and life of the rolling bearing; the cage can evenly distribute the rolling elements and guide the rolling elements to rotate for lubrication. Common rolling bearings are filled with grease to reduce ...
