Abstract
The utility model relates to dual cardan type U-joint, comprise a pair cross axle, on a pair cross axle, corner is equipped with oil sealing, a pair cross axle, four ends all overlap and have axle sleeve, spring is provided with between axle sleeve and spider center, a pair upper and lower two ends of cross axle is jointly overlapped and is had duplex fork, and a pair cross axle rear and front end is equipped with universal-joint fork.The axis body of a pair cross axle is cylinder type.Duplex fork is scalable.Be provided with pad between cross axle and duplex fork, between cross axle and universal-joint fork, be also provided with pad.The utility model has easy to maintenance, and fabricating cost is low, and technique is simple, and structure is simple, saves the advantage of energy consumption.
Description
Technical field
The utility model relates to a kind of universal joint, particularly dual cardan type U-joint.
Background technique
Dual cardan type U-joint is had by between centers the vicissitudinous diaxon of angle or mutual alignment to couple together, and make diaxon with the device of identical angular velocity transferring power, and it can overcome the variable speed sex chromosome mosaicism that common cardan universal joint exists.All connected by ball shape structure in the middle of general dual cardan type U-joint, complex structure, preparation process requires high, and fabricating cost is also larger simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides a kind of structure simple, technique list, the dual cardan type U-joint that fabricating cost is low, convenient for production.
The purpose of this utility model is achieved through the following technical solutions: dual cardan type U-joint, comprise a pair cross axle, on a pair cross axle, corner is equipped with oil sealing, a pair cross axle, four ends all overlap and have axle sleeve, spring is provided with between axle sleeve and spider center, a pair upper and lower two ends of cross axle is jointly overlapped and is had duplex fork, and a pair cross axle rear and front end is equipped with universal-joint fork.
Further improvement of the utility model is: the axis body of described a pair cross axle is cylinder type.
Further improvement of the utility model is: described duplex fork is scalable.
Further improvement of the utility model is: be provided with pad between described cross axle and duplex fork, is also provided with pad between described cross axle and universal-joint fork.
The utility model compared with prior art has the following advantages:
On a pair cross axle, corner is equipped with oil sealing, and position is more hidden, is not easy frayed, increases the service life; Be provided with spring between axle sleeve and spider center, due to the elastic force of spring, convenient installation duplex fork and universal-joint fork, because reaction force forces duplex fork to be connected tightr with cross axle with universal-joint fork; The axis body of cross axle is cylinder type, and universal joint axis body center mostly is Hexagon under normal circumstances, and columniform axis body rolls more convenient, rubs little; Duplex fork is scalable, and can regulate distance between a pair cross axle according to actual conditions, structure is simple; Be provided with pad between cross axle and duplex fork, be also provided with pad between described cross axle and universal-joint fork, pad can reduce phase mutual friction, reduces wear; Meanwhile, simply, cost is low, is convenient for changing for duplex fork and universal-joint fork structure.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-cross axle, 2-oil sealing, 3-duplex fork, 4-universal-joint fork, 5-axle sleeve, 6 springs, 7-pad, 8-axis body.
embodiment:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows a kind of mode of execution of the utility model dual cardan type U-joint, comprise a pair cross axle 1, on a pair cross axle 1, corner is equipped with oil sealing 2, more hidden, is not easy frayed, increases the service life; A pair cross axle, 1 four ends all overlap and have axle sleeve 5, spring 6 is provided with between axle sleeve 5 and cross axle 1 center, due to the elastic force of spring 6, convenient installation duplex fork 3 and universal-joint fork 4, because reaction force forces duplex fork 3 to be connected tightr with cross axle with universal-joint fork 4; ; A pair cross axle about 1 two ends is jointly overlapped and is had duplex fork 3, and a pair cross axle 1 rear and front end is equipped with universal-joint fork 4, and simply, cost is low, is convenient for changing for duplex fork 3 and universal-joint fork 4 structure; The axis body 8 of a pair cross axle 1 is cylinder type, and universal joint axis body center mostly is Hexagon under normal circumstances, and columniform axis body 8 rolls more convenient, rubs little; Duplex fork 3 is scalable, and can regulate distance between a pair cross axle according to actual conditions, structure is simple; Be provided with pad 7 between cross axle 1 and duplex fork 3, be also provided with pad 7 between cross axle 1 and universal-joint fork 4, pad can reduce friction each other, reduces wear; .
The foregoing is only and mode of execution of the present utility model is described; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
