Description
Technical field
The utility model relates to Fan Equipment technical field, particularly a kind of blower fan, electric machine assembly and centrifugal friction clutch thereof.
Background technique
In blower fan, motor is connected with impeller, runs impeller rotate by motor.When single phase motor band carries startup, wheel rotation inertia is large, but electric motor starting torque is little and fluctuation large, and this makes have vibration and noise during electric motor starting, even can cause the situation of electric motor starting failure time serious.
The method that single phase motor band carries startup first allows motor turn over friction starting drive usually, then impeller is rotated gradually.At present, the starting drive that rubs is made up of arc shape board and annular spring.Multi-disc arc shape board is arranged on impeller, and multi-disc arc shape board is positioned on same circle, and annular spring is centered around the outside of multi-disc arc shape board; The end of the rotatingshaft of motor is stretched in the hole that multi-disc arc shape board surrounds.Along with the rotatingshaft of motor rotates, annular spring to impose restriction power, so that produce frictional force between arc shape board and rotatingshaft to multi-disc arc shape board.But the frictional force that this structure produces is little along with rotating speed raises change, is unfavorable for rotary inertia when regulating different rotating speeds and starting load torque, the vibration existed when effectively cannot improve electric motor starting and start failed situation.
Therefore, how to reduce the rotary inertia and starting load torque that are subject to when rotatingshaft starts, reducing the infringement of vibration noise and electric motor starting failure, is the art personnel problem demanding prompt solutions.
Model utility content
In view of this, the utility model provides a kind of centrifugal friction clutch, to reduce the rotary inertia and starting load torque that are subject to when rotatingshaft starts, reduces the infringement of vibration noise and electric motor starting failure.The invention also discloses a kind of electric machine assembly and the blower fan with above-mentioned centrifugal friction clutch.
For achieving the above object, the utility model provides following technological scheme:
