Further, described wheel body through hole periphery is provided with some attachment holes, above-mentionedly respectively connects the step hole slot that the aperture is distributed in the through hole extending circumferentially, be used to connect the tapering ringfeder.

Further, described tapering ringfeder one end is along being circumferentially with bead, bead be provided with to the consistent attachment hole of wheel body, be fixed on the wheel body by link.

Further, described two tapering ringfeders are arranged in the through hole to wheel body in opposite directions, two tapering ringfeder axial lengths and less than hole depth to the wheel body through hole.

Further, the inner hole wall of its cover coupling shaft of described tapering ringfeder is provided with the location cotter way.

Further, described link is connecting bolt and nut, and connecting bolt and nut two ends are positioned at the step hole slot to the wheel body end.

The utility model ringfeder formula coupling is mainly used in the input on the various device and the link position of output shaft to wheel, as motor, CST, cylinder, speed reducer, role mainly rise transmission, axle with spool link etc.The utility model is made up of an outer body and two tapering ringfeders, installs and uses in the process, only need to put on the axle after its assembling, with a circle bolt with the tapering ringfeder with wheel body is connected and locks, it is held tightly on axle; During dismounting also by the jackscrew eye on the ringfeder (bolt and nut) with ringfeder with wheel body is backed down, just can easily unload.

The utlity model has advantages such as rational in infrastructure, easy for installation, can just can be not for convenience detach by special tools such as pulley extractors, time saving and energy saving.
