Abstract
The invention discloses an eccentric four ball pin type constant velocity universal joint. The eccentric four ball pin type constant velocity universal joint consists of a transmission shaft, a four-column groove shell, a four-ball pin bearing and the like, wherein the four-ball pin bearing consists of a four-pin frame, four eccentric ball rings, multiple roller needles and the like; the four eccentric ball rings are respectively in clearance fit with four uniformly distributed channels of the four-column groove shell to perform a rolling and sliding compound motion; and the four-ball pin is connected with an involute outer spline of the transmission shaft through an involute inner spline to realize an effect of transferring motions and torques.
Description
Art:
The present invention relates to a kind of universal joint, when master and slave moving axis has angular displacement and axial displacement simultaneously, bias four ball-pin type constant velocity universal joint of motion and torque can be transmitted.
Background technique:
Three ball pin bearings in conventional construction three ball pin style constant speed universal joint, only have three balls, and the ball of three even configurations is structures of symmetric type outer spherical surface, and show through long-term use, this structure has following deficiency at least:
(1) ball in three ball pin bearings of conventional construction is symmetrical structure, and bearing capacity is little, discontinuity, to improve bearing capacity, being forced to only have increased in size and specification, adding weight, and adding the difficulty of main frame geometrical arrangements.
(2) three ball pin bearings of conventional construction, ball only has three, and bearing capacity is not enough far away.
(3) housing of conventional construction, only have three raceway grooves, do not make full use of the useful space, cause material to increase, weight strengthens, and makes overall three ball pin style constant speed universal joint geometrical arrangements, bearing torque etc. not realize science, reasonable, best coupling.
Summary of the invention:
In order to overcome above-mentioned some deficiencies of conventional construction three ball pin style constant speed universal joint, the problems such as the present invention is to solve the structure that conventional construction exists is not compact, bearing capacity is low, easy inefficacy, devise a kind of bias four ball-pin type constant velocity universal joint of new structure.
The technical solution adopted for the present invention to solve the technical problems is:
Three ball pin design bearing are become four ball pin bearings, that symmetrical ball is designed to bias by outer spherical surface, one end that diameter is larger is contained in four post pot shell external diameter directions, the outer spherical surface of four eccentric balls and four post pot shell four circumferentially equally distributed raceway groove coordinate, and four eccentric ball endoporus are sold frame four bearing pins respectively and are booked the major diameter fit of needle roller with four.Four pin framves are connect by involute inner spline and transmission shaft involute outer spline, and are locked by shaft block ring.
The invention has the beneficial effects as follows:
Eccentric four ball-pin type constant velocity universal joints, can not only steadily, flexibly, reliably and accurately transmit motion and torque, and compact structure, rationally, friction factor is low, and transmission efficiency is high, improves bearing capacity, is convenient to processing, assembly and checkout, raising work efficiency.
Accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the positive insight structural map of longitudinal direction of the present invention, and Fig. 2 is the horizontal section side view of Fig. 1, in figure: (1) transmission shaft; (2) four post pot shells; (3) eccentric ball; (4) four pin frame (5) Steel Cable Baffle Rings; (6) back-up ring; (7) needle roller; (8) circlip for shaft
Embodiment:
In FIG: four groups of some needle rollers (7) are filled respectively on the quartering bearing pin of four pins frame (4), then respectively four eccentric balls (3) are loaded on the bearing pin with four groups of needle rollers (7) (eccentric ball internal diameter coordinates with needle roller group crest clearance), after four pin frame (4) four bearing pin tops are respectively charged into back-up ring (6), again four Steel Cable Baffle Rings (5) are respectively charged in the circlip groove of four bearing pins, for locking back-up ring (5), constitute totally four groups of single four ball pin bearings filling needle roller like this.Four eccentric balls (3) of this four ball pins bearing coordinate with the raceway groove of the circumferentially quartering of four post pot shells (2) respectively, four pins frame (4) of four ball pin bearings are coordinated by the involute outer spline of involute inner spline with transmission shaft (1), constitute eccentric four ball-pin type constant velocity universal joints of the present invention, realize when diaxon has angular displacement and axial displacement simultaneously, motion and torque can be transmitted.
