Abstract

The invention discloses a bearing for the belt pulley of a high-speed low-torque tensioner. The bearing comprises a bearing body, the bearing body is axially provided with a bearing inner ring and a bearing outer ring, and the bearing inner ring is provided with a first sealing ring mounting groove and a first steel ball mounting groove; a second sealing ring mounting groove and a second steel ball mounting groove are sequentially formed in the bearing outer ring; a sealing ring is arranged in a sealing cavity formed among the bearing inner ring, the bearing outer ring and a retainer; a framework is arranged in the sealing ring, the shape of the framework is matched with that of the retainer, the sealing ring is provided with a first sealing inner lip, a second sealing inner lip and a third sealing inner lip, and a bulge is arranged at the contact end of the third sealing inner lip; the sealing outer lip is in contact sealing with the second sealing ring mounting groove; and the outer wall of the bearing outer ring is provided with a knurling-shaped protruding part and an N-shaped groove. Torque and temperature rise can be reduced, and the phenomena of sliding of the sealing ring and falling of the sealing ring and outer ring accessories are improved.

Description

technical field [0001] The invention relates to the field of bearing manufacture, in particular to a bearing used on a pulley of a high-speed low-torque tensioner. Background technique [0002] The bearing outer ring of the existing tensioner belt pulley bearing is easy to fall off from the external injection molded part, and the torque is too large and it is not easy to use. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a bearing used on a pulley of a high-speed low-torque tensioner. [0004] In order to realize the purpose of the present invention, the technical scheme adopted is: [0005] A bearing for a high speed low torque tensioner pulley comprising: [0006] A bearing body, the shaft of the bearing body is provided with a bearing inner ring and a bearing outer ring, and the bearing inner ring is provided with a first sealing ring installation groove and ...
