Washing machine clutch washing, rinsing and dehydration work principle introduced
- Mar 13, 2018 -

From the analysis of the structure, in fact, the main components of the washing machine clutch include: brake disc, brake plate, clutch electromagnet, brake band, spring sleeve, anti-reversal spring, inner hub, torsion spring and gear reduction components. Let's introduce the working principle of washing, rinsing and dehydration.

 

In the work of washing and rinsing, the analysis should mainly be carried out from two aspects: 1. The working principle of the clutch when rotating clockwise: When the washing is performed, the electromagnet is not energized, and the moving iron core blocks the brake band so that the spring sleeve cannot rotate. The small torsion spring is released by the spring sleeve, and the torque of the pulley hub cannot be transmitted to the inner hub. At the same time, the torsion spring is wound tightly, the two inner hubs are integrated, and the torque of the dehydration tubing is transmitted to another inner hub.

 

The former inner hub is integrated with the brake disc. When the torque of the dehydration drum is transmitted to the brake disc, the brake disc generates friction and prevents the dewatering bucket from turning. At this time, the torque generated by the operation of the washing machine clutch motor is transmitted to the wave wheel shaft via the pulley and the gear assembly, and the pulsator rotates clockwise.

 

2. When counterclockwise rotates, the working principle of the clutch is analyzed: At this moment, the electromagnet is not energized, and the moving iron core blocks the brake band so that the spring sleeve cannot rotate. At the same time, the small torsion spring and the middle torsion spring are in the direction of loosening, and the torque cannot be transmitted to the second inner hub and the brake disc. The brake disc does not generate friction. The anti-reversal spring mounted on the brake disc seat shaft is wound tightly to generate a frictional force to prevent the dewatering bucket from turning. At this point, the torque generated by the operation of the motor is transmitted to the pulsator shaft via the pulley and gear assembly, and the pulsator can be rotated in the counterclockwise direction.

 

In addition, in the process of dehydration, the operating principle of the clutch structure can be understood as: Since the direction of rotation during dehydration is clockwise, the small torsion spring is wound tightly, and the torque is transmitted to the dehydration shaft of the clutch through the second inner hub. . The motor operates to generate power for transmission to the dehydration drum for high-speed operation.
