Bearing sealing ring

Abstract

The invention discloses a bearing sealing ring, which comprises a steel ring framework at the outer side and a rubber ring at the inner side, wherein the steel ring framework comprises a top beam and a vertical beam I, the top beam is horizontally arranged; a middle section of the vertical beam I is bent to 45 degrees; the rubber ring comprises a vertical beam II and a bottom beam; the vertical beam II is bonded with the lower section of the vertical beam I of the steel ring framework; a sealing lip is extended out of the bottom beam of the rubber ring; a C-type groove is formed in the bottom of the bottom beam, close to the sealing lip. The elastic deformation capability of the sealing ring can be improved; the service life of the sealing ring can be prolonged; meanwhile, the clamping capability between the sealing ring and a sealing groove opening of the outer ring of a bearing can be improved.

Description

technical field [0001] The invention relates to a bearing sealing ring, in particular to a bearing sealing ring with a spherical surface and a tapered hole. Background technique [0002] The bearing sealing ring is the main sealing part in the bearing. It not only keeps the grease in the bearing, but also prevents foreign debris or dust from entering the bearing, which can effectively improve the service life of the bearing. [0003] In the past, the bearing sealing ring was made of rubber as a whole. However, the bearing sealing ring made of rubber is not strong. In order to improve the strength of the bearing sealing ring, a steel ring frame is usually embedded in the rubber body of the bearing sealing ring. [0004] After embedding the steel ring skeleton, the strength of the bearing sealing ring has indeed been greatly improved, but with the increase in strength, the elastic deformation capacity of the bearing sealing ring has been weakened, which increases the difficult...

Problems solved by technology

[0003] In the past, the bearing sealing ring was made of rubber as a whole. However, the bearing sealing ring made of rubber is not strong. In order to improve the strength of the bearing sealing ring, a steel ring skeleton is usually embedded in the rubber body of the bearing sealing ring.

[0004] After embedding the steel ring skeleton, the strength of the bearing sealing ring has indeed been greatly improved, but with the increase in strength, the elastic deformation capacity of the bearing sealing ring has been weakened, which increases the difficulty of assembling the bearing sealing ring , the second is that it is difficult to control the interference between the sealing lip and the bearing ring, because when the interference changes, if the elastic deformation ability is strong, the friction between the sealing lip and the bearing ring will not change significantly , However, if the elastic deformation ability is weak, the friction between the sealing lip and the bearing ring will change significantly if the interference is slightly changed. If the friction is too large, the service life will be significantly affected. If the friction is too small, The sealing performance will be reduced
