Abstract
本发明涉及了一种平面推力轴承，包括外套；所述外套的截面呈U型，外套的底面的中心设置有通孔；所述外套内装配有由两个推力垫片、保持架和滚针组合的滚针轴承；所述外套内壁的顶侧设置有挡边，用于滚针轴承的上限位。本发明的一种平面推力轴承，适用于薄壁管柱，利用外套的外壁与管柱的内壁配合，以及采用法兰边与管柱的端面装配，滚针轴承可在外套内自由回转，并通过挡边对滚针轴承进行限位防脱，结构简单，性能可靠，简化了轴承与薄壁管柱的配合，装配便捷，降低了整体重量及制造成本。
The invention relates to a plane thrust bearing, comprising an outer casing; the section of the outer casing is U-shaped, and a through hole is arranged in the center of the bottom surface of the outer casing; the outer casing is equipped with two thrust washers, a cage and a needle roller. The combined needle roller bearing; the top side of the inner wall of the outer casing is provided with a rib for the upper limit of the needle roller bearing. The plane thrust bearing of the present invention is suitable for thin-walled pipe strings. The outer wall of the outer casing is matched with the inner wall of the pipe string, and the flange edge is used to assemble the end face of the pipe string. The needle roller bearing can freely rotate in the outer casing. The needle roller bearing is limited and prevented from falling off by the ribs, the structure is simple, the performance is reliable, the coordination between the bearing and the thin-walled pipe column is simplified, the assembly is convenient, and the overall weight and manufacturing cost are reduced.
Description
Technical field
The present invention 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.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of plain thrust bearing suitable for thin-walled tubing string, structure
Simply, reliable performance, it is convenient to assemble, and reduces overall weight and manufacturing cost.
The technical solution adopted by the present invention to solve the technical problems is: a kind of plain thrust bearing, including housing；It is described
The section of housing is U-shaped, and the bottom surface of housing is provided centrally with through-hole；It is equipped in the housing by two Thurst washers, protected
Hold the needle bearing of frame and needle roller combination；The top side of the outer casing inner wall is provided with rib, the upper limit for needle bearing.
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.
Beneficial effects of the present invention: a kind of plain thrust bearing of the invention is suitable for thin-walled tubing string, utilizes the outer of housing
The cooperation of the inner wall of wall and tubing string, and assembled using the end face of flange and tubing string, needle bearing can freely turn round in housing,
And limit anticreep is carried out to needle bearing by rib, structure is simple, reliable performance, simplifies matching for bearing and thin-walled tubing string
It closes, 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 of the present invention, the present invention is done below in conjunction with drawings and examples and is further retouched in detail
It states, the embodiment is only for explaining the present invention, does not constitute and limits to protection scope of the present invention.
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 present invention, all to be obtained by the way of equivalent replacement or equivalency transform
Technical solution fall within the scope of protection of the present invention.
