Description
Technical field
The utility model relates to transmission device field, particularly relates to a kind of plum-blossom type elastic coupling.
Background technique
Coupling is used to two axles (driving shaft and driven shaft) connected in different institutions to be made it jointly to rotate with the mechanical parts of transmitting torque.In the power transmission of high-speed overload, some coupling also has the effect of buffering, vibration damping and raising axle system dynamic performance.Coupling is made up of two halves, connects respectively with driving shaft and driven shaft.General power engine is mostly connected by means of coupling and working machine.Coupling is of a great variety, according to the change conditions of the relative position and position that are connected diaxon, can be divided into: 1. permanent coupling.Be mainly used in the place that relative displacement does not also occur diaxon requirement strict centering at work, structure is generally comparatively simple, easily manufacture, and diaxon transient speed is identical, mainly contains flange coupling, box coupling, clamping coupling etc.2. movable coupling.Be mainly used in the place that diaxon has deflection or has relative displacement at work, the method according to compensate for displacement can be divided into again rigidity moveable coupling and elasticity movable coupling.
Plum coupling structure is simple, without the need to lubrication, convenient for maintaining, be convenient to inspection, non-maintaining, can long-time running continuously.High-strength polyurethane elastic element wear-resistance and oil-resistance, bearing capacity is large, and long service life is safe and reliable.Working stability is reliable, has good vibration damping, buffering and electrical insulation properties.There is larger axial, radial and angular compensatory ability.Structure is simple, and radial dimension is little, lightweight, and rotary inertia is little, is applicable to high speed occasion.
Model utility content
The utility model provides the plum-blossom type elastic coupling that a kind of structure is simple, anti seismic efficiency is good.
The utility model is achieved through the following technical solutions:
A kind of plum-blossom type elastic coupling, comprise from half-coupling, main half-coupling, elastomer, describedly be respectively arranged with claw type tooth A, claw type tooth B from half-coupling, main half-coupling, described elastomer is provided with convex lobe, described from half-coupling, the assembly of main half-coupling coaxial line, the staggered occlusion of claw type tooth A, claw type tooth B, the convex lobe on elastomer is arranged in the gap of claw type tooth A, claw type tooth B, and described convex lobe is provided with elliptical aperture.Describedly radially offer arc gap from half-coupling, main half-coupling, offer gap vertically, radial gap and axial gap are partitioned into flexible body, flexible body and be provided with fastening piece between half-coupling, main half-coupling main body, can be fixed driven shaft, driving shaft and coupling by fastening piece.
Described claw type tooth A, claw type tooth B are the fillet of R5 with there being radius of curvature from half-coupling, main half-coupling main body joint.
Compared with prior art, the beneficial effects of the utility model are: the utility model, by being provided with elliptical aperture on the elastomeric convex lobe of plum coupling, reaching and alleviates the impact of coupling in running and the effect of vibrations.
