Bearing stop device

Abstract

The invention discloses a bearing bush stopping device, which comprises a bearing seat, a bearing bush and a stop slider. , the upper seat and the lower seat are combined in a plane, and at least one chute is added downward from the joint surface on both sides of the arc-shaped surface of the lower seat. After the upper seat and the lower seat are combined An accommodation cavity is formed, and a stop slider is arranged in the accommodation cavity, and the bearing bush adapted to the arc-shaped surface is arranged on the lower seat, and the arc-shaped surface of the bearing bush is additionally provided with the stop slider. A stop slide fits the contacting platform to limit movement of the bearing pad by contact between the platform and the stop slide. The bearing pad stopping device provided by the present invention can prevent the contact surface between the bearing pad and the bearing seat from friction and collision caused by the rotation and vibration of the bearing pad to cause abrasion.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a bearing stopper. Background technique [0002] Sliding bearings are machines with low friction and low noise through relative sliding to generate a dynamic pressure oil film to isolate moving and stationary parts. At present, spherical contact is generally used between the bearing pad and the bearing seat of the sliding bearing. The spherical surface size of the bearing pad is slightly smaller than the spherical surface size of the bearing seat. Bending (especially the flexible shaft) and the inclination caused by the misalignment of the bearings at both ends, improve the parallelism between the inner hole of the bearing bush and the rotating shaft. There is a set of pin hole anti-rotation structure with a large gap between them, and the anti-rotation ability is very limited.

AI Technical Summary

Problems solved by technology

At present, the bearing pad and the bearing seat of the sliding bearing generally adopt a spherical contact fit. The spherical size of the bearing pad is slightly smaller than that of the bearing seat. Bending (especially flexible shaft) and inclination caused by misalignment of bearings at both ends, improve the parallelism between the inner hole of the bearing pad and the shaft. There is a set of pin hole anti-rotation structure with a large gap between them, and the anti-rotation ability is very limited. When the bearing is started under heavy load, the rotating shaft may drive the bearing pad to rotate before the oil film is formed, causing friction and wear on the contact surface between the bearing pad and the bearing seat, and there is a slight difference. The size of the bearing seat cannot sufficiently suppress the vibration of the bearing pad, and the bearing pad may resonate under the force of the rotor, resulting in collision and wear with the bearing seat
