Principle Of Washing Machine Clutch
- May 09, 2018 -

 When washing, the working state of the clutch should be that the solenoid is de-energized, the drain valve is closed, and the positioning sleeve on the drainage valve connecting plate is separated from the brake lever. The brake lever is restored to its original position under the action of the brake spring, and the brake belt holds the brake wheel tight so that the dehydration shaft cannot rotate. At the same time, the pawl on the pawl fork dials the ratchet wheel through an angle under the action of the fork spring, and the square wire clutch spring installed in the ratchet wheel is loosened. When the pulley rotates in the forward direction, although it is the direction in which the square wire clutch spring is tightened, it has been loosened. When the pulley rotates in the reverse direction, the wire clutch spring is in the loosened direction, so the pulley is positive Turn or reversal, the washing axis and dehydration axis can not be connected as one. At this time, the dehydration shaft is braked by the brake belt and the torsion spring, and the pulley can drive the washing shaft and the pulsator on it to rotate (180 r/min) by the planetary gear deceleration mechanism to realize the washing function and the dehydration. The shaft and the dewatering bucket on it cannot rotate. During dehydration, the drain solenoid valve is energized and the drain valve is opened. The clutch lever fixed on the electromagnet pull rod pushes the brake lever forward, and the brake lever rotates around the pin shaft.
