What is the role of the special-shaped friction plate in the motor?
Lifting: The motor rotates clockwise to transmit the torque and motion to the large gear in the reduction box. The large gear is connected with the gear shaft through the left-handed thread. The clockwise motion input by the motor makes the large gear rotate counterclockwise, and the left thread makes the large gear shaft move in the opposite direction. Move to the right, compress the special-shaped friction plate, ratchet and brake disc. The brake disc transmits the torque to the gear shaft through the key, thereby driving the large ring gear on the drum and the drum to rotate clockwise, and the hook is realized by the wire rope and the pulley block.
Descending: The motor is reversed to make the large gear rotate counterclockwise, the left thread makes the large gear move to the left, the large gear is separated from the special-shaped friction plate, ratchet, and brake disc, resulting in a certain gap, and the free fall of the heavy object makes the drum and the large ring gear clockwise Rotation, when the speed of the gear shaft and the brake disc is equal to the speed of the motor, all the parts at the special-shaped friction plate are in a critical state of compression, and the falling speed of the heavy object exceeds the transmission speed of the motor; causing the mechanism to brake, the motor continues to rotate When the friction is turned on, the weight starts to descend again, so that the weight falls smoothly, and the pawl is combined with the ratchet in the process.
Stop: When the weight is in any position in the air, as long as the motor stops, the gap at the special-shaped friction plate will be eliminated by the movement generated during the fall of the weight. At this time, the ratchet is pressed down, and the gear shaft tends to rotate clockwise. The action mechanism of the claw is in a stationary state, and the falling motion of the heavy object is braked.
