General:

Hysteresis cable reel series JZ is widely used in port machinery, large lifting machinery, hydraulic machinery and engineering machinery needed translational motion of large machinery and equipment. Power source and to transmit control signals through a cable reel retractable cable. Apply to ports, power plants, water conservancy and other workplaces.

Structural characteristics of hysteresis cable reel:

1. Main Engine Main Engine by the deceleration, power head, slip ring collector box to form a whole. Power head is constituted by a motor, the hysteresis coupling, the planetary gearbox. Depending on the operating conditions can be single or multiple power head as hysteresis cable reel drive. Slip ring collector box for (signal) power transmission part, from the use can be divided into power transmission and signal transmission, according to the voltage level can be divided into 500v, 3kv,6kv, 10kv and so on. Collector slip ring wiring diagram refer to page 38.

2. Capacitance cable section Cable reel as parts of capacity can be divided into multi-row and single row winding wound. To facilitate transportation, diameter <2.6m reel for the overall structure; diameter> 2.6m reel two semicircular structure to be assembled on site by the user.

3. Hysteresis coupling working principle the use of magnetic hysteresis coupling is the main principle, the two magnetic semi-passive forms a magnetic deputy vice-through non-contact magnetic coupling, conducted torque transmission. Wherein a magnetic semi-permanent multi-pole magnet vice amount of disk constituting the other half of the magnetic induction vice is a magnetic disk, resulting in a resist this slip torque, which is a magnetic disc between two non-contact coupling thus drag (or brake) disk rotation. Adjust the size of the air gap between the magnetic vice, you can adjust the damping torque. When the air gap distance is locked during operation of the damping torque constant size can maintain long-term, and not with the active and passive vice relative speed changes. Based on a special hysteresis coupling torque coupling.

Hysteresis cable reel working principle:

Cable reel motor hysteresis coupling the power transmitted by the hysteresis coupling tune speedskating poor. You can get a stable constant torque, and then after the deceleration, the torque is transmitted to the amplified cable reel . Note that even if the process is to put the cable, cable reel drive motor is energized state should be, and phase sequence and closing cable in the same direction.

1. Release cable Through the cable drag torque to overcome the hysteresis coupling magnetic field, so that between the two plates slip generated, the cable reel on the release. The motor is powered.

2. Coiling cable When lifting equipment back row, drag force on the elimination of cable, cable reel winding direction of rotation is set towards the resumption of cable.

3. Out of service Each motor output shaft is equipped with a one-way shaft or motor with brake, to ensure sufficient braking torque when the motor is off, the cable will not fall by gravity from the reel.
