Frame structure of bearing sealing-ring with high strength

Abstract

The invention relates to a frame structure of a bearing sealing-ring with high strength, which comprises: a body (10) with Z-shaped; the upper end of the body (10) extends into an external lip (101) of the sealing-ring, the down end of the body (10) extends into a third lip (103) of an inner lip of the sealing-ring; a corner (102) is arranged between the upper end and the down end of the body (10), which is closer to the upper part of the body (10). The frame structure of the bearing sealing-ring with high strength has beneficial effects in that: a press-fitting distortion proportion of the sealing-ring is reduced from primary 50% to 5%; the thickness of the frame steel-plate of the sealing-ring is reduced more than 40%; the cost is reduced 15%; a loosening proportion of the sealing-ring is reduced from primary 5% to 0.2% in a same working condition.

Description

technical field [0001] The invention relates to a bearing, in particular to the sealing ring structure of the bearing. Background technique [0002] Depend on figure 1 It can be seen that the skeleton is in the shape of "7", and the sealing ring forms an outward tension by the corner of the skeleton at "1", so as to realize the tight fit of the sealing ring to the dust-proof groove of the outer ring of the bearing, but only at "2" Rubber, and rubber will produce plastic deformation after high temperature, so the contact between the sealing ring and the dust-proof groove of the outer ring will decrease, and the sealing ring will eventually become loose. At the same time, the sealing ring skeleton is suspended at "3", and the sealing ring is pressed During the process, the sealing ring is prone to deformation. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a skeleton structure of a high-strength bearing sealing ...
