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 circular runout between compensating shaft, but compensation rate is little, low precision.
5. plunger elastic caoutchouc coupling: but angle and circular runout between compensating shaft, but compensation rate is little, low precision.
6. single-unit cross joint coupling: but angle between compensating shaft, compensation rate is big, no return difference intermittence, but can not beat between compensating shaft.
7. the binodal cross saves coupling: but angle and circular runout between compensating shaft, and compensation rate is big, no return difference gap.But it is big to connect distance between axle head.
In common wind-power generating system, our widespread be movable coupling.But vertical sail type wind driven generator is to the technical requirements of coupling, except needs angle and circular runout between compensating shaft simultaneously, also need the compensating shaft end distance from unsteady variation.And required compensation rate is big, and need satisfy distance weak point between axle head, the situation that the return difference gap is little.Therefore existing portable coupling still can not satisfy the demand of practice technically fully.
