Problems solved by technology

Ordinary rolling bearings can work as long as they are injected with normal-pressure lubricating oil, but under a certain load, their maximum speed is limited. For example, the maximum speed of GB276-64 bearings is 40,000 rpm, so ordinary rolling bearings cannot be used to support high-speed Shaft

Abstract

The invention discloses a rolling bearing for a high-speed transmission mechanism. The rolling bearing comprises an outer ring, an inner ring and a rolling body, wherein the inner ring is arranged onthe inner side of the outer ring; a first track is arranged on the outer ring; the inner ring is provided with a second track opposite to the first track; the rolling body is arranged on a retainer; the retainer is arranged between the inner ring and the outer ring; the outer ring is provided with a groove and further comprises a filling member in cooperation with the groove; one side surface of the filling member is an arc surface with the same radian as the radian of the arc surface of the outer ring, and another side surface of the filling member is a flat surface, and the retainer is madefrom a metal having undergone rust prevention and added with chromate.

Description

technical field [0001] The invention relates to a rolling bearing, especially a rolling bearing used in a high-speed transmission mechanism. Background technique [0002] At present, in the field of machinery, high-speed transmission mechanisms that rotate more than 50,000 rpm are more and more commonly used. [0003] In the prior art, the shaft support in the high-speed rotary transmission mechanism generally needs to be supported by a pad-type high-speed bearing. When this high-speed bearing is working, high-pressure lubricating oil needs to be injected to make the shaft rotate in the high-speed bearing. Therefore, the general high-speed shaft The device needs to be equipped with a high-pressure oil injection device. Ordinary rolling bearings can work as long as they are injected with normal-pressure lubricating oil, but under a certain load, their maximum speed is limited. For example, the maximum speed of GB276-64 bearings is 40,000 rpm, so ordinary rolling bearings can...
