To another element or it may be simultaneously present centering elements.
Unless otherwise defined, all of technologies and scientific terms used here by the article is led with belonging to the technology of the utility model
The normally understood implication of technical staff in domain is identical.It is simply in the term used in the description of the utility model herein
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term as used herein " and/or " include
The arbitrary and all combination of one or more relevant Listed Items.
Please refer to Fig.1, a kind of vertical type sliding bearing thrust first 100, it is sheathed on outside shaft 400, including thrust collar body
10 and the backlash eliminating equipment 20 that is arranged on thrust collar body 10, pass through backlash eliminating equipment 20 and eliminate thrust collar body 10 and shaft 400
Between gap.
Through hole 102 and unthreaded hole 103 are provided in the axial direction with thrust collar body 10, the inner hole wall of through hole 102 circumferentially offers
With the looping pit 105 of the through hole 103 perforation, unthreaded hole 103 is arranged at intervals with through hole 102 and is connected with looping pit 105.In this reality
Apply in example, unthreaded hole 103 is symmetrical centered on through hole 102 and is evenly distributed on thrust collar body 10.It can be obtained from Fig. 1
Know, 105 diameter of looping pit is more than 102 diameter of through hole, and 102 diameter of through hole is greater than the diameter of unthreaded hole 103.
Backlash eliminating equipment 20, including semi-enclosed inner ring 201, semi-enclosed outer shroud 203 and connector 205,201 He of inner ring
Outer shroud 203 is contained in looping pit, and it is outer and along 10 axis direction of thrust collar body and inner ring that outer shroud 203 is sheathed on inner ring 201
Top clearance 101 is reserved between 201, connector 205 passes axially through unthreaded hole 103 and is connected with inner ring 201 and outer shroud 203, and
Drive outer shroud 203 mobile to the direction for reducing top clearance 101 while connector 205 is connected with outer shroud 203 vertically and squeeze
Inner ring 201 is pressed to be shunk to close to through hole direction, i.e., inner ring 201 is shunk to shaft 400, is eliminated between inner ring 201 and shaft 400
Gap.
Inner ring 201 and outer shroud 203 is are both provided with notch 210 (referring to Fig. 2), so that inner ring 210 is semi-enclosed, together
Also corresponding notch is offered on the outer shroud of sample, which is for the reserved constringency cleft of inner ring 201, outer shroud 203.Therefore exist
It is subject to external force freely to be scaled when extruding.In this way, by making outer shroud 203 to while the direction movement for reducing top clearance 101
Outer shroud 203 can also extrude inner ring 201 and be shunk to through hole direction, represent to be that the movement of vertical direction is changed into water on the diagram
Square to movement.When inner ring 201 is shunk to through hole direction, outer shroud 203 is under the reaction of inner ring to annular hole wall direction
Swell, so as to eliminate the gap between thrust collar body 10 and shaft 400.Therefore, need not be used compared to traditional assembly method
Interference fit, connector 205 are mechanically connected with inner ring 201, outer shroud 203, and assembly or disassembly is very convenient, in addition the backlash eliminating equipment
