Abstract

The invention discloses a sealing ring, which is used for sealing a bearing. The bearing has an inner ring and an outer ring, and balls are arranged between the inner ring and the outer ring. The sealing ring comprises a sealing ring main body, a supporting framework and a transom, wherein a first sealing lip and a second sealing lip are arranged on the sealing ring main body at intervals; the ends, away from the sealing ring main body, of the first sealing lip and the second sealing lip abut against the outer wall of the inner ring; the first sealing lip is arranged between the balls and thesecond sealing lip; the supporting framework is connected with the sealing ring main body and used for enabling the sealing ring main body to abut against the inner wall of the outer ring; the transomwindow is used for ventilation, and the transom window is arranged on the second sealing lip. By means of the transom window arranged on the second sealing lip, a negative pressure state between thefirst sealing lip and the second sealing lip can be improved, and the problem that the frictional resistance between the first sealing lip and the second sealing lip is increased due to the vacuum adsorption effect is solved.

Description

technical field [0001] The invention relates to the field of sealing structures, in particular to a sealing ring. Background technique [0002] In the existing bearing seal, the sealing lip of the bearing sealing ring is in close contact with the inner ring of the bearing to play a sealing role. During the operation of the bearing, there is air between the sealing lips of the bearing. Due to the heat generated during the operation of the bearing, the air between the sealing lips is heated and expands, and the internal pressure increases, and some of the air is discharged to the outside of the bearing. Reduce the vacuum adsorption effect generated under the external atmospheric pressure, resulting in a greatly increased bearing resistance and increased energy consumption. Contents of the invention [0003] The main purpose of the present invention is to provide a sealing ring, aiming at improving the problem of large bearing resistance existing in existing bearing seals. ...
