Abstract

The invention discloses a ball bearing with a sealing ring. The ball baring comprises an inner ring, an outer ring, a roll ball, a holder and a sealing ring and is characterized in that the outer ring is provided with a sealing groove I, the inner ring is provided with multiple stepped arc-shaped sealing grooves II, and the top end of the sealing ring is arranged in the sealing groove I; multiple sealing lips with different heights are extended from the bottom end of the sealing ring, the multiple sealing lips are respectively and correspondingly arranged in the arc-shaped sealing grooves II of the inner ring, the sealing slip on the outer side is in interference fit with the corresponding arc-shaped sealing grooves II, and fit clearances between the other sealing lips and the arc-shaped sealing grooves II increase successively from outside to inside. The ball bearing with the sealing ring is good in sealing effect, long in service life of bearing, and easy to install.

Description

Technical field [0001] The invention relates to a bearing, in particular to a ball bearing with a sealing ring. Background technique [0002] In order to adapt to the harsh environment and to achieve a good sealing effect, the current bearings usually need to adopt contact sealing. However, the friction torque of the contact seal is large, and the sealing material is quickly lost and deformed, which reduces the service life. Summary of the invention [0003] In view of the above problems, the present invention provides a ball bearing with a sealing ring with good sealing effect and long service life. To solve these problems, the present invention adopts the following technical solutions: [0004] A ball bearing with a sealing ring, comprising an inner ring, an outer ring, balls, a cage and a sealing ring, characterized in that: the outer ring is provided with a sealing groove one, and the inner ring is provided with a stepped arc Seal groove two, the top end of the sealing ring i...
