Description
Technical field
This utility model is related to train air-conditioning technical field, specially a kind of be applied to train air-conditioning device with damping
The centrifugal blower of device.
Background technology
The centrifugal blower of speed car air-conditioning device is typically mounted on the plate of air-conditioning device interior bottom of chamber, is bolted,
When air-conditioning device runs refrigeration or heating mode, centrifugal blower is all run up.And the vibration that blower fan produces can reach
In train passenger compartment, the comfortableness of passenger is caused to reduce.Meanwhile, vibration can also make bolt-connection position or the defect of metal
Position produces fatigue thus loosen or reduce the intensity at this position afterwards for a long time.
Content of the invention
Problem to be solved in the utility model is to provide a kind of train air-conditioning device centrifugal blower with damping device,
Setting buffer spring and damping unit between the bottom of centrifugal blower and mounting seat, realize the effective damping to centrifugal blower.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of train with damping device
Air-conditioning device centrifugal blower, two centrifugal blowers including mounting seat, being fixed in mounting seat and supporting driving electricity
Machine, described motor is located between two centrifugal blowers, the output shaft of motor run through electric machine casing, two ends respectively with from
Heart-wind syndrome machine is connected, and it is critical only that：Between centrifugal blower and mounting seat, between motor and mounting seat, it is provided with damping device,
Damping device includes buffer spring and damping unit, and described buffer spring is provided with even number and is symmetricly set on damping unit
Both sides.
Further, the upper junction plate fixing with centrifugal blower bottom and and mounting seat are also included in described damping device
Fixing lower connecting plate, described buffer spring two ends are fixed with upper junction plate and lower connecting plate respectively, and described damping unit is fixed
In lower connecting plate.
Further, described damping unit is hydraulic damper.
Further, described damping device is provided with least two groups between centrifugal blower and mounting seat.
Advantageous Effects of the present utility model are：Between centrifugal blower and mounting seat, motor and mounting seat
Between be provided with buffer spring and damping unit, the effectively vibration of buffering centrifugal blower and motor, lift train indoor comfort；
Due to driving two centrifugal blowers using a motor, the spring of setting is adapted to the output shaft axiality of motor
Error, buffer multi-faceted vibration, protect motor.
Below in conjunction with the accompanying drawings this utility model is described in detail.
