Abstract
The utility model discloses a rod end knuckle bearing. The rod end knuckle bearing comprises an outer ring, an inner ring, an inner ball and a rod end connected to the outer ring, wherein an oil groove is formed in the inner wall of the inner ring, an installing hole which is communicated with the oil groove is formed in the rod end in a cooperative mode, and an oil nipple is fixedly connected to one side of the rod end, and is communicated with the installing hole. The rod end knuckle bearing is reasonable in structural design, lubricating oil can be directly added to the rod end knuckle bearing through the oil nipple, lubricating oil stored in an oil cup can also be added to the rod end knuckle bearing, friction between the inner ball and the inner ring is reduced, abrasion of the inner ball and the inner ring is reduced, and the service life of the rod end knuckle bearing is prolonged.
Description
Technical field
The utility model belongs to joint shaft bearing technical field, relates to a kind of spherical plain bearing rod end.
Background technique
In recent years since, locomotive, the quiet automatic enabling gate of rail motor set railway carriage hydraulic pressure, spherical plain bearing rod end on high-end large-scale motor bus hydraulic starting door is in running using process, especially when passenger flow is frequently got on or off the bus, very easily moist moisture content, mud etc. are brought into, caused the phenomenons such as endosphere gets rusty, stuck, ablation.Common spherical plain bearing rod end does not have oil nozzle, very inconvenient during lubricating oil filling.
Model utility content
The purpose of this utility model is to provide a kind of spherical plain bearing rod end, has solved the technical problem of common spherical plain bearing rod end lubricating oil filling inconvenience in prior art.
The technological scheme that the utility model adopts is, a kind of spherical plain bearing rod end, comprise outer ring, inner ring, endosphere and be connected to the rod end on outer ring, the inwall of inner ring is provided with oil groove, in rod end, be equipped with the mounting hole communicating with oil groove, oil nozzle is fixedly connected on a side of rod end and is communicated with mounting hole.
Optimization as technique scheme: oil nozzle outer end is provided with lubricating cup.
Further optimization as technique scheme: be provided with internal thread in mounting hole.
Further optimization again as technique scheme: endosphere is flexibly connected with inner ring.
Further optimization as technique scheme: outer ring studs with bronze liner.Rod end body surface is zinc-plated.
The beneficial effects of the utility model are: the utility model reasonable in design, by oil nozzle, can add lubricant oil directly to this joint shaft bearing, also can utilize the lubricant oil storing in lubricating cup to add lubricant oil to this joint shaft bearing, reduced endosphere and inner ring between frictionalwear, extended working life of this joint shaft bearing.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the sectional drawing of A-A part in the utility model Fig. 1;
Wherein: 1 outer ring, 2 inner rings, 3 endospheres, 4 rod ends, 5 oil grooves, 6 mounting holes, 7 oil nozzles, 8 lubricating cups, 9 internal threads.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
This spherical plain bearing rod end of the present utility model, comprise outer ring 1, inner ring 2, endosphere 3 and be connected to the rod end 4 on outer ring 1, the inwall of inner ring 2 is provided with oil groove 5, is equipped with the mounting hole 6 communicating with oil groove 5 in rod end 4, and oil nozzle 7 is fixedly connected on a side of rod end 4 and is communicated with mounting hole 6.Oil nozzle 7 outer ends are provided with lubricating cup 8.In mounting hole 6, be provided with internal thread 9.Endosphere 3 is flexibly connected with inner ring 2.Outer ring 1 studs with bronze liner.Rod end 4 body surfaces are zinc-plated.
The utility model reasonable in design, by oil nozzle 7, can add lubricant oil directly to this joint shaft bearing, also can utilize the lubricant oil of lubricating cup 8 interior storages to add lubricant oil to this joint shaft bearing, reduced endosphere 3 and inner ring 2 between frictionalwear, extended working life of this joint shaft bearing.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
