Problems solved by technology

In actual use, the balls need to circulate and roll in the rolling rail of the bearing, causing the cavity between the inner and outer rings to undergo periodic drastic changes with the rolling of the balls, so the bearing grease is easily squeezed to both sides, causing the bearing The actual utilization rate of fat is very low
On the other hand, the durability of the existing bearing grease during long-term high-load use is relatively weak, and it is difficult to protect the smooth operation of the bearing when the bearing grease is not fully utilized

Abstract

The invention relates to the field of intelligent manufacturing, and particularly discloses a durable precision bearing. The durable precision bearing includes an inner ring, a first outer ring, a second outer ring, a third outer ring, a set of first balls and a set of second balls, the first outer ring and the second outer ring are correspondingly fixed to both sides of the third outer ring, andthe first outer ring, the second outer ring and the third outer ring together form an outer ring; the set of first balls is evenly distributed between the first outer ring and the inner ring, and theset of second balls is evenly distributed between the second outer ring and the inner ring; and the inner ring and the outer ring can rotate oppositely under common rolling support of the first ballsand the second balls, and together form a double-row ball bearing. According to the durable precision bearing, on the one hand, by optimizing the structure, the utilization efficiency of bearing grease is increased while the filling amount of the bearing grease is improved, and on the other hand, through optimization and innovation of the bearing grease, the durability and the stability are improved in the long-term use process.

Description

technical field [0001] The invention relates to the field of intelligent manufacturing, and specifically discloses a durable precision bearing. Background technique [0002] A precision machine tool is a machine that manufactures machines and is called an industrial master machine. Bearings are an important core component in precision machine tools. The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. For the durability and rotation accuracy of the bearing, it is necessary to ensure that the bearing is well lubricated, and the usual practice is to use bearing grease. In actual use, the balls need to circulate and roll in the rolling rail of the bearing, causing the cavity between the inner and outer rings to undergo periodic drastic changes with the rolling of the balls, so the bearing grease is easily squeezed to both sides, causing the bearing The actual utiliz...
