Abstract
The utility model discloses a coupler used for connecting square shafts. The coupler comprises a mounting seat, a coupling portion is arranged at the center of the mounting seat, and a cross inserting hole used for inserting the square shafts is formed in the coupling portion and is concentrically arranged with the mounting seat. The coupler has the advantages of simple structure, high safety and convenience in mounting and demounting.
Description
Technical field
The utility model relates generally to the connection for transmission technology of axle, relates in particular to a kind of coupling for connecting part's oblique crank Z.
Background technique
Coupling is widely used in the field such as machinery, hydraulic pressure, is mainly used in being connected between axle and axle, has good transferring rotational motion performance.
In prior art, on coupling, offer circular hole, axis body is inserted in circular hole, then axis body and coupling are fixed with tight fixed bolt, to realize the transmission rotatablely moving.There is following defect and deficiency in said structure: in rotary course, tight fixed bolt is subject to larger shearing, and the inefficacy that easily breaks, exists great potential safety hazard.
Model utility content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, safe, be convenient to handling the coupling for connecting part's oblique crank Z.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
For a coupling for connecting part's oblique crank Z, comprise fitting seat, described fitting seat is provided with shaft coupling portion in central position, and described shaft coupling portion offers the cross spliced eye for the square shaft of pegging graft, and described cross spliced eye arranges with fitting seat is concentric.
Further improvement as technique scheme:
Between the adjacent slot of described cross spliced eye, be provided with for coordinating with square shaft axial plane the inclined-plane of being close to.
Described shaft coupling portion and fitting seat are welded to connect.
Described fitting seat is cylindrical structure, and described fitting seat is provided with mounting hole.
Compared with prior art, the utility model has the advantage of:
Coupling for connecting part's oblique crank Z of the present utility model, this coupling comprises fitting seat, fitting seat is provided with shaft coupling portion in central position, shaft coupling portion offers the cross spliced eye for the square shaft of pegging graft, cross spliced eye arranges with fitting seat is concentric, it is simple in structure, only four of a square shaft corner need be inserted in four slots of cross spliced eye, can complete the installation of square shaft and this coupling, do not need to carry out fastening with special clamping bolt the other side oblique crank Z on the one hand, its installation and removal are all very convenient, be convenient to safeguard and change, on the other hand, in rotation process, four faces of square shaft are all stressed, do not exist clamping bolt because of the shearing inefficacy that breaks, greatly improve the Security of this coupling.

Embodiment
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
Fig. 1 to Fig. 4 shows the embodiment of the utility model for the coupling of connecting part's oblique crank Z, this coupling comprises fitting seat 1, fitting seat 1 is provided with shaft coupling portion 2 in central position, shaft coupling portion 2 offers the cross spliced eye 21 for the square shaft 3 of pegging graft, cross spliced eye 21 and the concentric setting of fitting seat 1, it is simple in structure, only four of square shaft 3 corner need be inserted in four slots of cross spliced eye 21, can complete the installation of square shaft 3 and this coupling, do not need to carry out fastening with special clamping bolt the other side oblique crank Z 3 on the one hand, its installation and removal are all very convenient, be convenient to safeguard and change, on the other hand, in rotation process, four faces of square shaft 3 are all stressed, do not exist clamping bolt because of the shearing inefficacy that breaks, greatly improve the Security of this coupling.
In the present embodiment, between the adjacent slot of cross spliced eye 21, be provided with for coordinating with square shaft 3 axial planes the inclined-plane 22 of being close to, this inclined-plane 22 coordinates and is close to square shaft 3 axial planes, increase the area of contact of shaft coupling portion 2 with square shaft 3, be conducive on the one hand the even transmission of power, improved the stationarity of rotating, on the other hand, can scratch square shaft 3, ensure the working life of square shaft 3.
In the present embodiment, shaft coupling portion 2 is welded to connect with fitting seat 1, adopts Type of Welding, makes shaft coupling portion 2 and fitting seat 1 form entirety, is conducive to concentrating of driving force, has reduced power consumption.
In the present embodiment, fitting seat 1 is cylindrical structure, is convenient to machine shaping, and fitting seat 1 is provided with mounting hole 11, and the installation of being convenient to whole coupling is fastening, and it is simple in structure, easy to use.
Although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model.Any those of ordinary skill in the art, in the situation that not departing from technical solutions of the utility model scope, all can utilize the technology contents of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solutions of the utility model,, all should drop in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to the utility model technical spirit.
