In, prominent 10 vulcanization of increased outer ring is fixed on axial limiting groove, not only improves the company of elastic buffer resilient cushion 7 and outer sleeve 3
Connect firmness of the connection；Due also to this TC bearing is in petroleum drilling and mining tool in use, outer sleeve 3 will receive axial impact and vibration
It is dynamic, elastic buffer resilient cushion 7 and 3 axial limiting of outer sleeve are made by outer ring prominent 10 at this time, the axial direction (left and right that outer sleeve 3 is subject to
It is two-way) shock and vibration can be dashed forward by outer ring and 10 pass to entire elastic buffer resilient cushion 7, avoid outer sleeve 3 and elasticity
The vulcanization of bumper and absorbing shock pad 7 part is ripped, and the service life and reliability of elastic buffer resilient cushion 7 are further increased.
As shown in Fig. 1, it is equipped with resilient cushion in 3 left end of outer sleeve and card slot, 7 left end peripheral hardware of elastic buffer resilient cushion is installed
There is left ring prominent 11, prominent 11 outer ring surfaces of left ring and right side, which vulcanize, to be fixed in resilient cushion installation card slot right part；In left ring prominent 11
The sliding friction outer cylinder 2 in left side is externally provided with outer ring chuck 12, and outer ring chuck 12 is sleeved in the left part of resilient cushion installation card slot, outside
12 right end of ring chuck and the left side vulcanization of left ring prominent 11 link together.The prominent 11 pairs of outer sleeves 3 of left ring and sliding friction outer cylinder 2
The effect of connection is not only acted as, cushioning buffer effect also is played to sliding friction outer cylinder 2；This TC bearing is in petroleum drilling and mining tool
In use, its sliding friction outer cylinder 2 is between outer sleeve 3 except through receiving other than shock and vibration, sliding friction outer cylinder 2 itself
Also can be directly by axial shock and vibration to the left, in this case, left ring prominent 11 is placed in 12 right side of outer ring chuck and subtracts
Between shake pad installation card slot right side, part axial impact and vibration can be absorbed, damping, buffering is played to sliding friction outer cylinder 2
Effect.
