Abstract
The invention relates to a three-joint bearing type universal joint which consists of a housing, a transmission shaft, a spider, a roller pin, an elastic collar, a snap spring, a retainer ring and a joint bearing. The spider is installed on the transmission shaft by a spline and is axially positioned by a spring collar, the joint bearing is arranged on each sub-pin of the spider by the roller pin, the end of the sub-pin is positioned by the snap spring and the retainer ring, the joint bearing is respectively matched with a channel of the housing, the cross-section of the channel is composed of a circular arc section and two grooves, and the outer margin of the joint bearing is clamped into the groove. When a driving shaft and a driven shaft have axial displacement and angular displacement, the three-joint bearing type universal joint disclosed in the invention not only can stably, flexibly, reliably and precisely transmit movement and torque, but also has flexible gyration, no clamping stagnation and high carrying capacity. The three-joint bearing type universal joint has the advantages of compact and reasonable structure, low friction coefficient, high transmission efficiency and low making cost, and test results show that all properties are better than those of the original three-axis ball pin type universal joint.
Description
Technical field:
The present invention relates to a kind of coupling, more specifically to a kind of three-knuckle bearing type cardan joint.
Background technique:
In the prior art, the three ball pin style universal joint of conventional construction, its housing body has three raceway grooves that diameter is less, and what be mated is three traditional ball pin bearings, the ball of three groups of symmetric form spheres is arranged and has the punching press back-up ring and the jump ring structure, show that through test and use following deficiency is arranged:
(1) its housing body does not make full use of the useful space, and raceway diameter is too little, comprises that three ball pin bearing specifications are all very little, has reduced bearing capacity.
(2) the three ball pin style universal joint of conventional construction only has the sphere of activities of two degrees of freedom.The restriction of structure thus can not be satisfied the job requirement that existing corner has slip again sometimes, usually occurs catching phenomenon in the work.
(3) owing on the three ball pin style gimbal structure,, will increase matching gap if will turn round flexibly, seek cause not shock-resistant, noise is big, the life-span reduces.
Summary of the invention:
The objective of the invention is to provide at the prior art deficiency a kind of simple in structure, bearing capacity is high, can satisfy the existing axial displacement of master and slave moving axis transmits the three-knuckle bearing type cardan joint of moving fortune and torque when angular displacement is arranged.
The objective of the invention is to realize by following measure: a kind of three-knuckle bearing type cardan joint, comprise housing, transmission shaft, spider, needle roller, circlip, jump ring and back-up ring is characterized in that also having: joint shaft bearing; Described spider is installed on the transmission shaft by spline and by the check ring axially locating, described joint shaft bearing is installed on spider each minute bearing pin by needle roller, the distribution axle head is by back-up ring and jump ring location, joint shaft bearing cooperates with the raceway groove of housing respectively, described raceway groove cross section is that arc section and two grooves are formed, and described joint shaft bearing outer rim snaps in the groove.
Compared with prior art, since the three-knuckle bearing type cardan joint that has adopted the present invention to propose, when master and slave moving axis has axial displacement and angular displacement, steadily, flexibly, reliably and accurately transmitting movement and torque, and revolution is flexible, no catching phenomenon, the bearing capacity height.Compact structure of the present invention, reasonable, friction factor is low, the transmission efficiency height, and fabricating cost is low, and every after testing performance all is better than original three flexible member assembly.

Fig. 2 is Fig. 1 embodiment A-A sectional view.
Fig. 3 is the vertically positive sectional structure chart of Fig. 1 embodiment joint shaft bearing.
1. transmission shafts among the figure, 2. housing, 3. back-up ring, 4. spider, 5. jump ring, 6. needle roller, 7. joint shaft bearing, 8. elastic scheibe, 9. outer ring, 10. inner ring, 11. circular arcs, 12. grooves.
Embodiment:
Below in conjunction with accompanying drawing embodiment is elaborated:
In Fig. 1～one embodiment of the present of invention shown in Figure 3, a kind of three-knuckle bearing type cardan joint comprises: housing 2, transmission shaft 1, spider 4, needle roller 6, circlip 8, jump ring 5 and back-up ring 3, joint shaft bearing 7.Described spider 4 is installed on the transmission shaft 1 by spline and by check ring 8 axially locating, described joint shaft bearing 7 is installed on spider each minute bearing pin by needle roller 6, the distribution axle head is by back-up ring 3 and jump ring 5 location, joint shaft bearing cooperates with the raceway groove of housing respectively, described raceway groove cross section is that arc section 11 and two grooves 12 are formed, and described joint shaft bearing outer rim snaps in the groove.
Substituted original ball with joint shaft bearing among the present invention, joint shaft bearing can move in housing on the one hand, the Internal and external cycle of joint shaft bearing can relatively rotate on the other hand, transmits the difficult problem of moving fortune and torque when having satisfied the existing axial displacement of master and slave moving axis and again angular displacement being arranged.The present invention has obtained the economic benefit that significant progress is become reconciled.
The foregoing description is not construed as limiting the invention, and adopts the technological scheme that form obtained that is equal to replacement or equivalent transformation in every case, all drops within protection scope of the present invention.
