Abstract
The invention relates to an elastic coupler. The elastic coupler comprises an output end half coupler body, a nylon pin, an input end half coupler body, an elastic gasket, a metal pin bush and a plug screw, the corresponding positions of the contact faces of the output end half coupler body and the input end half coupler body are provided with pin holes, the nylon pin is arranged in the pin holes of the output end half coupler body and the input end half coupler body, the nylon pin is sleeved with the metal pin bush, and the outer side of the pin hole of the output end half coupler body and the outer side of the input end half coupler body are provided with threads, the plug screw matched with the threads of the pin holes are screwed into the pin holes, and the nylon pin and the metal pin bush are coaxially fixed. According to the elastic coupler, due to the fact that the metal pin bush is additionally arranged outside the nylon pin, the shearing stress is converted into pressure stress to be evenly distributed on the whole nylon pin, the transmission torque of the whole coupler is improved, and the service life of the nylon pin is prolonged.
Description
Technical field
The present invention relates to a kind of elastic coupling flexible coupling.
Background technique
Nylon pin elastic coupling flexible coupling is widely used as the equipment of conventional transmission moment of torsion, conventional nylon pin elastic coupling flexible coupling is made up of output terminal half-coupling, nylon pin, back-up ring and input end half-coupling, by nylon pin, two half-couplings are linked together, because nylon pin is directly placed in the half-coupling pin-and-hole of two rigidity, when running, the moment of torsion that nylon pin bears is larger, easily weares and teares and ruptures.
Summary of the invention
The object of the invention is to overcome above defect, a kind of elastic coupling flexible coupling of more high pulling torque is provided.
Technological scheme of the present invention is, a kind of elastic coupling flexible coupling, it comprises output terminal half-coupling, nylon pin, input end half-coupling, output terminal half-coupling and input end half-coupling surface of contact opposite position are provided with pin-and-hole, nylon pin is placed in the pin-and-hole of output terminal half-coupling and input end half-coupling, also comprise elastic washer, metal guide, plug screw, described metallic pin is set in the outside of nylon pin, the outside pin-and-hole of output terminal half-coupling and input end half-coupling is provided with screw thread, the plug screw matching with pin-and-hole screw thread is screwed in pin-and-hole, by nylon pin and metallic pin cover axial restraint.
Preferably, described plug screw is hexagonal socket head plug.
Preferably, between described plug screw and coupling, be provided with elastic washer.
Preferably, the cross section of described metal guide is C type.
Useful technique effect of the present invention is, owing to increasing metal guide in nylon pin outside, shearing stress is converted into pressure stress to be evenly distributed on whole nylon pin, thereby improve the moment of torsion that coupling transmits, improve the working life of nylon pin, hexagonal socket head plug restriction nylon pin and metallic pin are enclosed within the axial float in pin-and-hole, have reduced vibration and noise.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
Embodiment
Below in conjunction with accompanying drawing and example, the present invention will be further described.
With reference to accompanying drawing, a kind of elastic coupling flexible coupling, it comprises output terminal half-coupling 1, nylon pin 3, input end half-coupling 6, elastic washer 2, metal guide 4, hexagonal socket head plug 5, output terminal half-coupling 1 and input end half-coupling 6 are provided with pin-and-hole at the opposite position of surface of contact, outside at pin-and-hole is provided with screw thread, first the nylon pin 3 that is enclosed with metal guide 4 is filled in pin-and-hole, the cross section of metal guide 4 is C type, then be screwed into hexagonal socket head plug 5 in the outside of output terminal half-coupling 1 and input end half-coupling 6, at the flexible packing ring 2 of hexagonal socket head plug 5 underlay, tightening hexagonal socket head plug 5 is delivered in nylon pin 3 and the moment of torsion of metal guide 4 common compositions in pin-and-hole, prevent its axial float, and the pretightening force providing by elastic washer 2 realizes locking functions.
