Description
Technical field
The utility model relates to design bearing fields, more particularly to a kind of plain thrust bearing.
Background technique
Plain thrust bearing installation site requires to have enough planar support bearing shims and to consider that the axial direction of bearing is solid
Determine problem, and a kind of thin-walled tubing string of steering column plain thrust bearing does not have corresponding space to meet the dress of general bearing
Match, increases weight and cost that tubing string wall thickness undoubtedly increases tubing string.The characteristics of for bearing applying working condition (load is small), therefore examine
A kind of plain thrust bearing for tubing string feature is developed in worry, is easily installed and is used and reduce manufacture installation cost.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of plain thrust bearing suitable for thin-walled tubing string,
Structure is simple, reliable performance, and it is convenient to assemble, and reduces overall weight and manufacturing cost.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of plain thrust bearing, including housing；
The section of the housing is U-shaped, and the bottom surface of housing is provided centrally with through-hole；It is equipped in the housing by two thrust pads
The needle bearing of piece, retainer and needle roller combination；The top side of the outer casing inner wall is provided with rib, the upper limit for needle bearing
Position.
The outer wall of the housing is provided for the fitting surface installed with pipe string internal wall.
It is additionally provided with flange on the outer wall of the housing, is assembled for being positioned with tubing string end face.
The retainer is arranged between two Thurst washers, and the needle roller is arranged in retainer.
The utility model has the beneficial effects that a kind of plain thrust bearing of the utility model, is suitable for thin-walled tubing string, utilize
The outer wall of housing and the inner wall of tubing string cooperate, and are assembled using the end face of flange and tubing string, and needle bearing can be in housing
It freely turns round, and limit anticreep is carried out to needle bearing by rib, structure is simple, and reliable performance simplifies bearing and thin-walled
The cooperation of tubing string, it is convenient to assemble, and reduces overall weight and manufacturing cost.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of plain thrust bearing of embodiment；
Fig. 2 is a kind of schematic diagram of plain thrust bearing of embodiment and the schematic diagram of thin-walled tubing string assembly.
Specific embodiment
In order to deepen the understanding to the utility model, the utility model is done further below in conjunction with drawings and examples
Detailed description, the embodiment are only used for explaining the utility model, do not constitute and limit to the protection scope of the utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of plain thrust bearing, including housing 1 are present embodiments provided；The housing 1 is cut
Face is U-shaped, and the bottom surface of housing 1 is provided centrally with through-hole；It is equipped in the housing 1 by two Thurst washers 2, retainer 3
The combined needle bearing with needle roller 4；The top side of 1 inner wall of housing is provided with rib 5, the upper limit for needle bearing；Institute
The outer wall for stating housing 1 is provided for the fitting surface installed with pipe string internal wall；Flange is additionally provided on the outer wall of the housing 1
6, it is assembled for being positioned with tubing string end face；The retainer 3 is arranged between two Thurst washers 2, and the needle roller setting is being protected
It holds in frame 3.
A kind of plain thrust bearing of the present embodiment is suitable for thin-walled tubing string, utilizes the outer wall of housing and the inner wall of tubing string
Cooperation, and assembled using the end face of flange and tubing string, needle bearing can freely turn round in housing, and by rib to rolling
Needle bearing carries out limit anticreep, and structure is simple, reliable performance, and it is convenient to assemble, and reduces overall weight and manufacturing cost.
Above-described embodiment should not in any way limit the utility model, all by the way of equivalent replacement or equivalency transform
The technical solution of acquisition is all fallen in the protection scope of the utility model.
