Device and method for testing waterproof performance of bearing seal ring

Abstract

The invention relates to a device and a method for testing the waterproof performance of a bearing seal ring. The device comprises a base; a test container, a driving system and a torque sensing system are arranged on the base; the test container is used for containing an acid and alkaline solution; a through hole matched with a tested bearing in shape and size and used for fastening a bearing outer ring of the tested bearing is formed in one side wall of the test container, so that when the tested bearing is installed in the through hole, and the bearing seal ring on one side is in contact with the solution; a servo motor of the driving system enables a bearing inner ring to rotate under the action of a driving shaft; the torque sensing system is used for detecting and recording a torqueof the driving shaft; whether the solution enters the tested bearing or not is judged according to the change of the torque, so that the waterproof performance of the bearing seal ring is detected; and if the solution permeates the bearing inner ring and the bearing outer ring, the tested bearing is corroded to increase the torque. The device is convenient to operate, low in cost, wide in application and suitable for testing of the waterproof performance of all sealed bearings.

Description

technical field [0001] The invention relates to a bearing testing device and a testing method, in particular to a bearing sealing ring waterproof performance testing device and a testing method thereof. Background technique [0002] The bearing sealing ring is a kind of bearing seal, especially a ball bearing sealing ring. There are two circular protrusions extending upward on one end surface of the ring, and the inner diameter of the smaller diameter protrusion is the same as The dust-proof groove of the inner ring of the ball bearing matches, and the protrusion with a larger diameter matches the dust-proof groove of the outer ring of the ball bearing; the inner diameter of the sealing ring is not smaller than the inner diameter of the inner ring of the ball bearing. It has the characteristics of preventing grease leakage, external impurities entering the bearing, and avoiding damage to balls and cages by external forces. It is widely used on bearings.

Problems solved by technology

[0003] During the actual use of the bearing, there may be liquid in contact with one side of the bearing. If the sealing performance of the bearing sealing ring is not good, the liquid will enter the inside of the bearing and flow out from the other side of the bearing, which will affect the performance of the bearing and the service life of the bearing.

At present, there is a lack of detection devices on the market to detect the waterproof performance of bearing sealing rings according to the actual application conditions of bearings.
