Abstract
The utility model relates to a special sealing end cover for grease injection of a universal joint, which mainly solves the problems of insufficient grease quantity and environmental pollution caused by the fact that grease overflows under movement of inner star wheels relative to outer star wheels after grease is injected into the universal joint. The special sealing end cover for grease injection of the universal joint is characterized in that an end cover body (1) is hermetically buckled at one ends of the outer star wheels (2); at least three supporting bodies (3) are arranged on the same circumference of the bottom of the end cover body (1); the upper end faces of the supporting bodies (3) correspond to the lower end faces of the inner star wheels (4); the outer bottom surface of the end cover body (1) is a plane. The sealing end cover positions the inner star wheels, so the inner star wheels do not move relative to the outer star wheels after the grease is injected into the universal joint, grease overflow in a picking, placing or transportation process of the universal joint is avoided, and environmental pollution is avoided.
Description
Technical field
The utility model relates to the assistant tool that injects lubricant grease in a kind of universal joint, is specifically related to greasing Special seal end cap in a kind of universal joint.
Background technique
Rzeppa universal joint energy constant-speed transmission power and can change operating angle and carry out telescopic slide, be usually used in the steering drive axle of car.Rzeppa universal joint is comprised of out star wheel, star-wheel, retainer and steel ball, and out star wheel also claims outer raceway, and star-wheel also claims interior raceway, and retainer also claims the ball cage.In order to solve the manual problem of injecting the grease contamination working environment of rzeppa universal joint, Chinese patent CN200910098752.5 discloses a kind of grease filling device in universal joint, there is following technological deficiency in use in this grease filling device in universal joint: after the greasing that completes a universal joint, the universal joint of having annotated lubricating grease is taken out, star-wheel is relative out star wheel play under the self gravitation effect, and then the grease of star-wheel below exceeds the out star wheel end face, in entering the process of next procedure, will stick to because of carelessness on other article or utensil, still can pollute working environment, grease in universal joint is scurried out in company with star-wheel, cause the oil quantity deficiency.In addition, after the universal joint greasing, also can be stained with grease on the sealing gasket of seat board top, location, after next universal joint was put into the location seat board, the out star wheel end face also can adhere to grease, easy befouling environment in picking and placeing or transporting process.
The model utility content
In order to solve the relative out star wheel play of universal joint star-wheel after greasing, cause grease to deviate to make oil quantity to reach not the problem of befouling environment, the utility model provides greasing Special seal end cap in a kind of universal joint, in this universal joint, greasing Special seal end cap positions star-wheel, star-wheel out star wheel play relatively not after the universal joint greasing, universal joint does not pollute the environment in picking and placeing or transporting process.
The technical solution of the utility model is: in a kind of universal joint, greasing Special seal end cap comprises end cover body, described end cover body is sealingly fastened on an end of out star wheel, on the same circumference in the bottom of end cover body, be provided with at least three supports, the upper-end surface of support is corresponding with the lower end surface of star-wheel, and the outside bottom surface of end cover body is plane.
In described end cover body, be provided with metal inner lining, metal inner lining is injected with the oil resistant rubber layer outward.
Described support is circular-arc, and support is four.
The utlity model has following beneficial effect: owing to taking such scheme, before the universal joint greasing, first end cover body is fastened on to an end of out star wheel in universal joint, support is propped up star-wheel, has gap between star-wheel and support inner bottom surface, from the middle greasing in star-wheel top.During greasing, the outside bottom surface of end cover body is placed on the enterprising line operate of platform and gets final product, and after greasing finished, universal joint took out together with end cover body, during assembling, takes off end cover body again, and end cover body can be reused after cleaning.Because support is located star-wheel, star-wheel out star wheel play relatively not after the universal joint greasing, universal joint grease in picking and placeing or transporting process can not deviate from or adhere on other object, the problem of befouling environment while thoroughly having solved the universal joint grease.
The accompanying drawing explanation
Accompanying drawing 1 is structure sectional view of the present utility model.
Accompanying drawing 2 is structural representations of end cover body 1 in Fig. 1.
1-end cover body in figure, 2-out star wheel, 3-support, 4-star-wheel, 5-metal inner lining, 6-oil resistant rubber layer.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
By Fig. 1 in conjunction with shown in Figure 2, in a kind of universal joint, greasing Special seal end cap comprises end cover body 1, described end cover body 1 is sealingly fastened on an end of out star wheel 2, on the same circumference in the bottom of end cover body 1, be provided with at least three supports 3, the upper-end surface of support 3 is corresponding with the lower end surface of star-wheel 4, and the outside bottom surface of end cover body 1 is plane.Owing to taking technique scheme, before the universal joint greasing, first end cover body 1 is fastened on to an end of out star wheel 2 in universal joint, support 3 is propped up star-wheel 4, between star-wheel 4 and support 3 inner bottom surface, has gap, from the middle greasing in star-wheel 4 tops, grease filler can adopt the disclosed grease filling device in universal joint of Chinese patent CN200910098752.5 of mentioning in background technique, also can adopt other quantitative grease device, as quantitative oil filling pump, quantitative pouring oil gun etc.During greasing, the outside bottom surface of end cover body 1 is placed on the enterprising line operate of platform and gets final product, and after greasing finished, universal joint took out together with end cover body 1, during assembling, takes off end cover body 1 again, can reuse after end cover body 1 cleans.Because 3 pairs of star-wheels 4 of support are located, star-wheel 4 out star wheel 2 plaies relatively not after the universal joint greasing, universal joint grease in picking and placeing or transporting process can not deviate from or adhere on other object, the problem of befouling environment while thoroughly having solved the universal joint grease.
In described end cover body 1, be provided with metal inner lining 5, the outer oil resistant rubber layer 6 that is injected with of metal inner lining 5.Metal inner lining 5 provides larger support force, avoids support 3 in the greasing process to produce distortion.Oil resistant rubber layer 6 contacts with out star wheel 2, avoids scratching out star wheel 2 surfaces.
Described support 3 is circular-arc, and support 3 is four.Guarantee the surface of contact of support 3 and star-wheel 4, during greasing, star-wheel 4 can not be offset, more steady.
