Abstract
The invention relates to a double-cardan universal joint. The double-cardan universal joint comprises a pair of universal joint pins, and oil seals are arranged at the corners of the pair of universal joint pins. The four tail ends of the pair of universal joint pins are each sleeved with a shaft sleeve, and springs are arranged between the shaft sleeves and the centers of the universal joint pins. The upper ends and the lower ends of the pair of universal joint pins are sleeved with double-cardan forks together. Universal joint forks are arranged at the front ends and the rear ends of the pair of universal joint pins. Shaft bodies of the pair of universal joint pins are cylindrical. The double-cardan forks are extensible. Gaskets are arranged between the universal joint pins and the double-cardan forks. Gaskets are also arranged between the universal joint pins and the universal joint forks. The double-cardan universal joint has the advantages of being convenient to maintain, low in manufacturing cost, simple in technology and structure, and capable of reducing energy consumption.
Description
Technical field
The present invention 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 object of the invention is to overcome above deficiency, providing a kind of structure simple, technique list, the dual cardan type U-joint that fabricating cost is low, convenient for production.
Object of the present invention 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 present invention is: the axis body of described a pair cross axle is cylinder type.
Further improvement of the present invention is: described duplex fork is scalable.
Further improvement of the present invention 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 present invention 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 invention;
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 the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 shows a kind of mode of execution of dual cardan type U-joint of the present invention, 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 explanation embodiments of the present invention; be not limited to the present invention, for a person skilled in the art, within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
