Abstract
The utility model provides an elastic coupling which comprises a coupling body. A through hole penetrates through the two ends of the coupling body, at least six blind holes are evenly distributed in the end face of the coupling body in a circumferential direction, the blind holes are communicated through a circular groove, a threaded hole is formed in the side wall of the coupling body, and the threaded hole is communicated with the through hole. The elastic coupling is simple in structure and convenient and fast to mount, has good radial bending resistant and torsional stiffness, and greatly reduces the maintenance quantity.
Description
Technical field
The utility model relates to a kind of coupling, particularly a kind of elastic coupling flexible coupling.
Background technique
in engine truck is taken turns motor driven systems, driving gear generally is directly installed in the traction electric machine rotating shaft, do not need to adopt elastic coupling flexible coupling, but on high-power locomotive, the power of traction electric machine reaches 1600KW, if adopt traditional motor driven systems, driving gear is arranged on two bearing outer ends of motor by the motor shaft cantilever, main, while from gear, meshing, motor shaft produces crooked, cause the master gear unbalance loading, the transmission shaft of traction electric machine driving end will bear very large load simultaneously, to greatly shorten the working life of principal and subordinate's gear and traction electric machine bearing, increased the repair and maintenance amount.
The model utility content
The technical problem that (one) will solve
The technical problems to be solved in the utility model be to provide a kind of simple in structure, the repair and maintenance amount is little, elastic coupling flexible coupling with large radially bending resistance and torsional rigidity.
(2) technological scheme
For solving the problems of the technologies described above, the utility model provides a kind of elastic coupling flexible coupling, comprise coupling body 1, described coupling body 1 two ends are penetrated with through hole 5, the end face of described coupling body 1 circumferentially is evenly equipped with at least six blind holes 3, described blind hole 3 is communicated with by circular groove 4, and the sidewall of described coupling body 1 offers tapped hole 2, and described tapped hole 2 is communicated with described through hole 5.
Further, two chamfers of described through hole 5.
Further, the sidewall of described blind hole 3 is inclined-plane.
Further, the sidewall of described circular groove 4 is inclined-plane.
Further, described blind hole 3 is eight.
(3) beneficial effect
The utility model elastic coupling flexible coupling, simple in structure, quick and easy for installation, have preferably radially bending resistance and torsional rigidity, greatly reduce the repair and maintenance amount.
Description of drawings
Fig. 1 is the structural representation of the utility model elastic coupling flexible coupling;
Fig. 2 is the half sectional view of the utility model elastic coupling flexible coupling.
Embodiment
Consult Fig. 1～Fig. 2, the utility model provides a kind of elastic coupling flexible coupling, comprise coupling body 1, be penetrated with through hole 5 at these coupling body 1 two ends, end face at coupling body 1 circumferentially is evenly equipped with at least six blind holes 3, and blind hole 3 is communicated with by circular groove 4, at the sidewall of coupling body 1, offers tapped hole 2, tapped hole 2 is communicated with through hole 5, is used for positioning shaft; In order to reduce burr and convenient the installation, at two chamfers of through hole 5; In order to facilitate location and installation, the sidewall of blind hole 3 is inclined-plane, and namely blind hole 3 integral body are frustoconic shape, and the sidewall of circular groove 4 is inclined-plane, and namely the cross section of circular groove 4 is trapezoidal; In order to improve torsional rigidity, in the present embodiment, blind hole 3 is eight.
The utility model elastic coupling flexible coupling, simple in structure, quick and easy for installation, have preferably radially bending resistance and torsional rigidity, greatly reduce the repair and maintenance amount.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
