Abstract
The invention relates to a universal joint bearing with a wear mark, and belongs to the field of vehicle body structural design for railway vehicles. The universal joint bearing with the wear mark comprises an upper movable joint and a lower movable joint, wherein the upper movable joint is of a bowl-shaped structure, the lower movable joint is connected with the upper movable joint, and a wear dial gauge is arranged on an inner ring of the upper movable joint. The universal joint bearing with the wear mark provided by the invention is capable of intuitively measuring the wear condition of the upper movable joint, thus deciding whether parts are replaced or not. Therefore, the damages of a material are greatly reduced, and the cost is decreased.
Description
Technical field
The present invention relates to a kind of universal joint bearing with abrasion mark of patent of the present invention, belong to track vehicle body structure design field.
Background technique
Low-floor tram car is needed by little curve for realizing, and vehicle modules design is shorter, and each intermodule uses universal joint bearing to connect.This universal joint bearing its to connecting vehicle modules, transmitting the hauled load of vehicle and the effect of brake load, and the weight of the floating car module of carrying and passenger weight, is the critical component of low-floor tram car.
This universal joint bearing constantly moves in vehicle operation, and Bearing inner constantly wears away, when bearing wear to a certain extent time, must change in time, and in vehicle life cycle regular test bearing wear intensity, to determine whether replacing.But low-floor tram car compact structure, service clearance is little, again because universal joint bearing is three direction rotary structures, directly measure more difficult under the condition do not dismantled onboard, and test inaccuracy, usually occur in life cycle, namely change the phenomenon of bearing.
Therefore, be necessary to design a kind of wear intensity that accurately can judge this universal joint bearing compared with energy accurate measurement method, determine whether to change this bearing.
Summary of the invention
The present invention is directed to the universal joint bearing that above-mentioned deficiency provides band abrasion mark.
The present invention adopts following technological scheme:
The present invention relates to a kind of universal joint bearing with abrasion mark, comprise top movable joint, lower removable joint; Described top movable joint is bowl shaped structure, and lower removable joint is connected with top movable joint, and described top movable joint inner ring is provided with wearing and tearing dial.
The present invention relates to the universal joint bearing of described band abrasion mark, described top movable joint inner ring is provided with the whole circle of wearing and tearing dial and is provided with 60 scales; Be divided between long lattice scale area and between little lattice scale area.
The present invention relates to the universal joint bearing of described band abrasion mark, described long lattice scale area is 60 °, is 6 ° between little lattice scale.
Beneficial effect
The universal joint bearing of band abrasion mark provided by the invention, can measure the abrasion condition in its top movable joint intuitively, thus determine whether change component.Greatly save the damage of material, reduce cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is top movable articulation structure schematic diagram of the present invention;
Fig. 3 is cross-sectional view of the present invention.
In figure, 1 is top movable joint, and 2 is lower removable joint, and 3 is dial.
Embodiment
For making the object of the embodiment of the present invention and technological scheme clearly, below in conjunction with the accompanying drawing of the embodiment of the present invention, the technological scheme of the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiments.Based on described embodiments of the invention, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, belongs to the scope of protection of the invention:
The universal joint bearing of band abrasion mark, comprises top movable joint 1, lower removable joint 2; Described top movable joint 1 is in bowl shaped structure, and lower removable joint 2 is connected with top movable joint 1, and described top movable joint 1 inner ring is provided with wearing and tearing dial 3.
Top movable joint 1 inner ring is provided with the whole circle of wearing and tearing dial 3 and is provided with 60 scales; Be divided between long lattice scale area and between little lattice scale area.Long lattice scale area is 60 °, is 6 ° between little lattice scale.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
