The driving part and the driven part of the washing machine clutch use the friction between the contact surfaces, or use the liquid as the transmission medium, or use the magnetic transmission to transmit the torque, so that the two can be temporarily separated and gradually engaged. During the transmission process, the two parts are allowed to rotate with each other.
The washing machine clutch consists of several concentric shafts, generally two to three. The clutch process is controlled by cpu-relay-shift fork-gear-holding. The brake part is holding brake, and the action process is the same, but the position is different. The center of the large pulley is a square hole, which is fixed on the square surface of the gear shaft by a tightening nut. The clutch sleeve is also sleeved on the gear shaft, and the large pulley, gear shaft and clutch sleeve are integrated.
The outer diameter of the clutch sleeve is the same as the outer diameter of the outer shaft. The square wire clutch spring is installed on the outer diameter of the clutch sleeve and outer sleeve. The upper end of the square wire clutch spring is in a freely tightened state. In the hole, the lower end and the ratchet wheel are connected as a whole, and when the ratchet wheel rotates, the lower end of the square wire clutch spring is driven to rotate.
In the free state, the inner diameter of the square wire clutch spring is small, and the square wire clutch spring is screwed on the outer diameter of the clutch sleeve and the outer shaft. The brake band is wrapped on the outer diameter of the planetary clutch. One end of the brake band is fixed to the clutch housing with screws, and the other end is fixed to the lower end of the brake lever. When the brake lever rotates around the pin shaft, the brake can be relaxed and tightened. belt.
The brake lever can also adjust the radial position of the pawl on the clutch lever on the ratchet wheel by adjusting the screw, so that the pawl can extend into or out of the ratchet wheel, so as to change the working state of the clutch. When washing, the working state of the washing machine clutch should be that the electromagnet is powered off, the drain valve is closed, and the positioning sleeve on the drain valve connecting plate is separated from the brake lever. Under the action of the brake spring, the brake lever returns to its original position, and the brake band holds the brake wheel tightly so that the dehydration shaft cannot rotate.
