Description
Technical field
The utility model relates to a kind of Hooks coupling universal coupling, relates in particular to a kind of axle head spheroid formula Hooks coupling universal coupling.
Background technique
In mechanical system, when angular displacement, see various forms of coupling being arranged in action through regular meeting.In the heavy machinery driving mechanism, what use at first is steel slide block type coupling, because this coupling quick abrasion, steel consumption are big, be eliminated gradually, the substitute is cross universal coupling, although cross universal coupling has many good qualities, but it the momentary angular speed of driving shaft and driven shaft can occur when single use asynchronous, thereby rotational speed and torque is all changed, and this variation meeting is along with the change of angular displacement greatly and sharply strengthens, therefore, cross universal coupling is not suitable for using under the situation of high rotating speed, Angular Displacement.In order to overcome above-mentioned shortcoming, people have been developed synchro-nizing universal coupling with ball and sacker, synchro-nizing universal coupling with ball and sacker has solved the problem that above-mentioned coupling exists, but, synchro-nizing universal coupling with ball and sacker comprises all multiple components such as steel band hoop, outer cover, ball cage, star sleeve and snap ring, complex structure makes its manufacturing procedure complexity, cost height.
In sum, coupling of the prior art exists complex structure, manufacturing procedure complexity, technical problem that cost is high.
The model utility content
The purpose of this utility model be to provide a kind of simple in structure, processing technology is simple, and axle head spheroid formula Hooks coupling universal coupling with low cost.
For achieving the above object, the utility model provides a kind of axle head spheroid formula Hooks coupling universal coupling, comprise driving shaft and driven shaft, the driving shaft axle head is the blank pipe shape, the driven shaft axle head is a spheroid, spheroid and the socket of driving shaft axle head blank pipe, driving shaft is connected by spheroid movingly with driven shaft, it is characterized in that, coupling also comprises plurality of balls, and the driving shaft axle head is provided with some circular holes, and spheroid upper edge driven shaft axial direction is provided with some arc grooves, ball is arranged in the circular hole, and is connected movingly with arc groove.
According to the described axle head spheroid of the utility model preferred embodiment formula Hooks coupling universal coupling, its ball is a spheroid.
According to the described axle head spheroid of the utility model preferred embodiment formula Hooks coupling universal coupling, its ball is a cylindrical body.
The driving shaft of the utility model axle head spheroid formula Hooks coupling universal coupling is connected movingly with driven shaft, and be connected movingly with ball by on driven shaft axle head spheroid, groove being set, the axis angle of driving shaft and driven shaft diaxon can change, when the diaxon axis angle changes, ball can move reciprocatingly in arc groove, also can rotate in arc groove.The utility model axle head spheroid formula Hooks coupling universal coupling has been cancelled the component such as steel band hoop, outer cover, ball cage, star sleeve and snap ring of synchro-nizing universal coupling with ball and sacker, has advantage simple in structure, that manufacturing procedure is few, with low cost.

Fig. 2 is the sectional view of the utility model axle head spheroid formula Hooks coupling universal coupling;
Schematic perspective view when Fig. 3 has angle for the driving shaft of the utility model axle head spheroid formula Hooks coupling universal coupling and driven shaft.
Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1 to Fig. 3, a kind of axle head spheroid formula Hooks coupling universal coupling comprises: driving shaft 1, driven shaft 2 back-up rings 3 and four balls 4.
In this example, ball 4 can be that spheroid can also be a cylindrical body.In addition, need to prove, adopt four arc grooves 211, four balls 4 and four circular holes 11 in this example, but the utility model is not limited thereto, in actual applications, can select the quantity of arc groove 211, ball 4 and circular hole 11, the arc groove 211 that is less than four can be set according to the actual loading intensity of Hooks coupling universal coupling, four above arc grooves 211 also can be set, and the quantity of ball 4 and circular hole 11 is according to the quantity setting of arc groove 211.Therefore, more than adopt just example of four arc grooves 211, four balls 4 and four circular holes 11, and be not used in qualification the utility model.
In this example, need to prove that driving shaft 1 axle head inwall is set to arc surface, it can also be set to non-arc surface.
In this example, the circular hole 11 of driving shaft 1 axle head is set to through hole, comes off for preventing ball 4, adopts in the mode of driving shaft outside socket back-up ring 3 ball 4 is blocked.Yet, the utility model is not limited thereto, for example, circular hole 11 can also be set to square opening, in addition, circular hole 11 can also be arranged to groove, and not be arranged to through hole, this kind mode can directly be blocked ball 4 by the outer wall of driving shaft, does not need again at driving shaft outside socket back-up ring 3.Therefore, more than adopt circular hole is set, and the circular hole setting is through hole and cooperates the mode of back-up ring is an example, and be not used in qualification the utility model.
The driving shaft 1 of the utility model axle head spheroid formula Hooks coupling universal coupling adopts with driven shaft 2 and is connected movingly, ball 4 is connected movingly with arc groove 211, driving shaft 1 can change with the axis angle of driven shaft 2 diaxons, when the diaxon axis angle changed, driving shaft 1 rotation drove driven shaft 2 rotations by ball 4 and arc groove 211.At this moment, ball 4 can move reciprocatingly in arc groove 211, also can rotate in arc groove.When two axis did not have angle, 211 of ball 4 and arc grooves did not have motion, and ball 4 rotates with the driving shaft 1 and the rotation of driven shaft 2, does not have other motions.In this example, need to prove that in actual applications, can set the excursion of this axis angle according to actual needs, the utility model does not limit the excursion of this angle.
More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop in the protection domain of the present utility model.
