Equipped with the through-hole passed through for the transmission shaft, it is equipped with elastic cushion between the through-hole and the transmission shaft, is set on the elastic cushion
There are several evenly spaced guide rods.
Preferably, connecting plate is equipped between the elastic cushion and the taper disk, the connecting plate is hollow structure, described
Several rest pads are equipped in connecting plate, the rest pad is trapezoidal shape.
Preferably, the gap location of the rest pad and the connecting plate is filled with carbon fiber.
Preferably, damping device is equipped between the connecting plate and the taper disk.
Preferably, the damping device includes the damping chamber being arranged between the connecting plate and the taper disk, described
Damping is intracavitary to be equipped with damping spring.
The utility model has the following beneficial effects: general only use bolt fastening for the transmission shaft of motor and impeller, pass
