[background technique]
Coupling is parts conventional in mechanical transmission.The flexible coupling had elastic component, not only can compensate the relative displacement of two between centers, and has the ability of buffering absorbing.This kind of coupling obtains and is widely used, and kind gets more and more.And the existing flexible coupling general structure all more complicated had elastic component, number of parts is more, and price is more expensive, and radial dimension is comparatively large, some elastic coupling flexible coupling buffering and damping capacity more weak.
[model utility content]
The purpose of this utility model is to provide a kind of torsion spring elastic coupling flexible coupling, and this coupling can improve the buffering of elastic coupling flexible coupling and the ability of absorbing, can simplify its structure simultaneously, reduce costs, reduce radial dimension.
The utility model is achieved through the following technical solutions:
A kind of torsion spring elastic coupling flexible coupling, comprise the torsion spring for driving torque, one end of described torsion spring is connected with the end of driving shaft one end, and the other end of torsion spring is connected with the end of driven shaft one end.
The end that the end that described driving shaft is connected with torsion spring, driven shaft are connected with torsion spring offers screw-shaped groove respectively, and by this groove, driving shaft and driven shaft can be screwed in the hole at torsion spring two ends respectively, realize torsion spring respectively with the connection of driving shaft and driven shaft.
Described driving shaft is identical with the pitch of torsion spring with the pitch of the screw-shaped groove that the end that the end that torsion spring connects, driven shaft are connected with torsion spring is offered respectively.
Described driving shaft is identical with the helix angle of torsion spring with the lead angle of the screw-shaped groove that the end that the end that torsion spring connects, driven shaft are connected with torsion spring is offered respectively.
The sectional shape of the screw-shaped groove that the end that the end that described driving shaft is connected with torsion spring, driven shaft are connected with torsion spring is offered respectively selects circular arc, and the diameter of described circular arc is identical with the gauge of wire of torsion spring.
The large footpath of the screw-shaped groove that the end that the end that described driving shaft is connected with torsion spring, driven shaft are connected with torsion spring is offered respectively is less than the central diameter of torsion spring.
