At present, the cross-axle universal shaft coupling on market in its working procedure, when driving shaft rotate 1 week, the corresponding rotation of driven shaft 1 week.
But the instantaneous transmission ratio of diaxon is in continuous change, be attended by the additional loads such as vibration, impact, it is not ideal enough to add lubricating condition, these all can produce infringement to cross-axle universal shaft coupling, increase the friction between itself and link, and there is noise, reduce the working life of coupling.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of universal coupling with spider, the bearing including cross axle, the half-coupling be connected with described cross axle and be connected with described half-coupling, described cross axle is formed with some trunnion journals, described trunnion journal end face is formed with elastic arc cover, and described trunnion journal inside is formed with oil canal.
Further, described elastic arc cover interior edge face is formed with elasticity convex arc block, described trunnion journal end face is formed with concave arc groove, described elasticity convex arc block and described concave arc slot fit.
Further, described trunnion journal end is formed with oil guide slot, and described oil guide slot outside is formed with pump nozzle, and described pump nozzle is connected with outside oil supplying device.
Further, described oil canal is that decussate texture is distributed in described cross axle inside.
Further, described elastic arc cover is rubber arc cover, and described rubber arc cover inside scribbles urethane material.
The beneficial effects of the utility model are: be connected with cross axle by half-coupling and be connected with bearing, form a complete cross axle type coupling, when the diaxon running connected, cross axle is attended by the additional loads such as vibration, impact, by being formed in the elastic strain of the elastic arc cover on trunnion journal end face by counterweight balance, oil canal is utilized to pass into lubricant oil, moment keeps desirable lubricating condition, reduce the infringement that cross-axle universal shaft coupling is produced, reduce the friction between itself and link, improve the working life of coupling.

In figure, 102 is half-coupling, and 101 is cross axle, and 1011 is oil canal, and 1012 is oil guide slot, and 1013 is pump nozzle, and 1015 is trunnion journal, and 103 is elastic arc cover.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figures 1 to 3, the preferred embodiment that provides of the utility model.
Universal coupling with spider, can be widely used in transmitting torque in the mechanical axis system of lifting, engineering transportation, mine, oil, coal and other Heavy duty maching industry.
Universal coupling with spider, include cross axle 101, half-coupling 102 and bearing, wherein, cross axle 101 is connected with half-coupling 102, half-coupling 102 is connected with bearing, cross axle 101 is formed with some trunnion journals 1015, and trunnion journal 1015 end face is formed with elastic arc cover 103, trunnion journal 1015 inside is formed with oil canal 1011.
Utilize the cross structure of cross axle 101, realize transmitting torque angularly between diaxon, in the process of axle running, the additional loads such as vibration can be produced to cross axle type coupling, by elastic arc cover 103, additional load be balanced, reduce the wearing and tearing to universal coupling with spider, in the process of axle running, lubricant oil is introduced in cross axle 101 by oil canal, lubricates cross axle 101, reduces the friction between cross axle 101.
Be connected by half-coupling 102 with cross axle 101 and be connected with bearing, form a complete cross axle type coupling, when the diaxon running connected, cross axle 101 is attended by the additional loads such as vibration, impact, by being formed in the elastic strain of the elastic arc cover 103 on trunnion journal 1015 end face by counterweight balance, oil canal 1011 is utilized to pass into lubricant oil, moment keeps desirable lubricating condition, reduce the infringement that cross-axle universal shaft coupling is produced, reduce the friction between itself and link, improve the working life of coupling.
Particularly, elastic arc overlaps on 103 interior edge faces and is formed with elasticity convex arc block, trunnion journal 10115 end face is formed with concave arc groove, elasticity convex arc block and concave arc slot fit, utilize convex arc block and concave arc groove to closely cooperate, elastic arc cover 103 and trunnion journal 1015 are closely linked together, and can reduce at convex arc block and concave arc slot fit place the additional load that cross axle is subject to, improve the working life of cross axle 101, thus improve the working life of cross axle shaft type Hooks coupling universal coupling.
105, trunnion journal end is formed with oil guide slot 1012, oil guide slot 1012 outside is formed with pump nozzle 1013, pump nozzle 1013 is connected with outside oil supplying device, the lubricant oil of outside oil supplying device is injected into oil guide slot 1012 by pump nozzle 1013, store in oil guide slot 1012, after the oil in oil canal 1011 is finished, the lubricant oil in oil guide slot 1012 will be supplied to oil canal 1011 automatically, moment keeps desirable lubricating condition, thus improves the working life of cross axle 101.
Particularly, oil canal 1011 is distributed in cross axle inside in decussate texture, realizes the lubrication of cross axle 101 everywhere.
Elastic arc cover 103 is rubber arc cover, and rubber arc cover inside scribbles urethane material, smears urethane material and contributes to damping vibration power.Certainly, in practice, other materials can be adopted as elastic arc cover, such as silica gel, be not limited to rubber.
What describe in above-described embodiment and specification just illustrates principle of the present utility model and most preferred embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
