Description
Technical field
The utility model relates to a kind of coupling, is specifically related to a kind of universal quadrature coupling that power is connected between the power-actuated rotary main shaft of wind-power electricity generation apoplexy and the generator that is used for.
Background technique
Coupling is of a great variety, according to the relative position of coupled diaxon and the change conditions of position, can be divided into:
(1) permanent coupling.The place that is mainly used in the strict centering of diaxon and relative displacement does not take place at work, structure is generally simpler, make easily, and the 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 relative displacement is arranged at work, can be divided into movable coupling of rigidity and the movable coupling of elasticity again according to the method for compensate for displacement.Mainly contain following coupling:
1. sliding cross coupling: but beat between compensating shaft, compensation rate is big, but low precision and can not compensating shaft between angle.
2. single-unit elastic metallic coupling: but angle between compensating shaft, compensation rate is medium, and no return difference intermittently but can not be beated between compensating shaft.
3. binodal elastic metallic coupling: but angle and circular runout between compensating shaft, and compensation rate is medium, no return difference gap.But connect distance between axle head.
4. plum blossom elastic caoutchouc coupling: but angle and beating between compensating shaft, but compensation rate is little, low precision.
5. plunger elastic caoutchouc coupling: but angle and beating between compensating shaft, but compensation rate is little, low precision.
