Description

A kind of plum blossom elastic coupling flexible coupling
Technical field
The utility model relates to coupling technical field, specifically, and particularly a kind of plum blossom elastic coupling flexible coupling.
Background technique
Coupling makes its barycenter or principal inertia axis add shaft axis with it not overlap for various reasons, the phenomenon of unbalanced centrifugal inertia force, the even power of centrifugal inertia and dynamic deflection (vibration shape) will be produced in the running, this energy imbalance must cause the vibration of axle system, thus shadow error, axle stand under load and the distortion produced, pedestal distortion, bearing wear, temperature variation (expanding with heat and contract with cold) affect the normal work and use life-span of machine, coupling join diaxon and produce relative displacement due to many factors such as the relative movement between foozle, installation, parts.Generally, diaxon relative displacement is difficult to avoid, but the direction of displacement that the axle system transmission under different working condition produces, namely the size of axis (x), radial direction (y), angle (a) and displacement amount is different.Existing coupler structure more complicated, need often to lubricate, maintenance cost is high, and adaptability is strong not.
Model utility content
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, a kind of plum blossom elastic coupling flexible coupling is provided, it devises boss for holding up plum blossom elastomer, be conducive to the installation of this type coupling, and define the axial float of plum blossom elastomer when coupling operates in two plum blossoms half connection cavity, improve the running stability of coupling.
The utility model solves the technological scheme that its technical problem adopts: a kind of plum blossom elastic coupling flexible coupling, comprises left half-coupling, right half-coupling and plum blossom elastomer; Described left half-coupling and right half-coupling are all provided with center hole, the end face of described left half-coupling and described right half-coupling is provided with quincunx double wedge, described plum blossom elastomer central position is provided with cylindrical hole, described left half-coupling and right half-coupling are all provided with boss and are positioned at inside double wedge, double wedge bi-side are concave arc shape, described quincunx elastomer is arranged between left half-coupling and right half-coupling, in the space between the double wedge that described quincunx elastomeric cylinder boss is placed in described left half-coupling and described right half-coupling.
As preferably, in the center hole of described left half-coupling, be processed with keyway.
As preferably, in the center hole of described right half-coupling, be processed with keyway.
As preferably, described plum blossom elastomer is provided with six cylinder boss.
As preferably, described left half-coupling and right half-coupling are all provided with three double wedges.
The utility model compared with prior art has the following advantages: devise boss for holding up plum blossom elastomer, be conducive to the installation of this type coupling, and define the axial float of plum blossom elastomer when coupling operates in two plum blossoms half connection cavity, improve the running stability of coupling, extend plum blossom elastomeric working life simultaneously.
