Abstract
Description
(1) Technical field
[0001] The invention relates to the technical field of transmission, in particular to a servo clutch device and its operating mode. (2) Background technology
[0002] Clutches are commonly used torque transmitting components in mechanical transmission systems. Common clutches include magnetic powder clutches, electromagnetic clutches, friction or hydraulic mechanical clutches, and the like. The main function is to isolate the torque transmission of the master and slave parts, realize the gradual engagement / disengagement of the master and slave parts, and transmit the working torque.
[0003] The magnetic powder clutch adds magnetic powder between the master and slave parts, and the torque can be conveniently controlled by adjusting the excitation current of the slave part, and the torque has a certain linear relationship with the excitation current, and the excitation current has a wide range. Proportional. And the magnetic powder clutch has a relative...
Examples
Embodiment 1
[0039] The structure of the embodiment 1 of the servo clutch device of the present invention is as follows: figure 1 As shown, the input shaft 1 is connected to the first rotor 3, the first rotor 3 is an outer rotor, embedded with permanent magnet poles, inside it is the second rotor 4, and the second rotor 4 is an inner rotor, which is wound on the iron core winding, the second rotor 4 is connected to the output shaft 8 of the device. The input shaft 1 and the output shaft 8 are on the same straight line. The first rotor 3 provides the second rotor 4 with a radial magnetic field. In this embodiment, the permanent magnet poles embedded in the first rotor 3 and the iron core and windings of the second rotor 4 constitute a permanent magnet synchronous motor, a switched reluctance motor, or a DC motor. A position sensor 2 is installed on the first rotor 3 . A B position sensor 7 is installed on the second rotor 4 shaft, and the A position sensor 2 and the B position sensor 7 a...
Embodiment 2
[0050] The structure of embodiment 2 of the servo clutch device of the present invention is as follows: figure 2 As shown, the first rotor 3 and the second rotor 4 are opposite to each other, maintaining an air gap, and the other structures are the same as those in Embodiment 1. The two form an axial magnetic circuit structure, and the direction of the air gap magnetic field between the two rotors is axial.
[0051] The operating mode of the embodiment 1 and 2 of the servo clutch device of the present invention is as follows: the servo driver 6 works in the torque servo mode, and the torque value of the master-slave part of the servo clutch linearly follows the torque setting value of the servo driver 6. During the process, the motions of the clutch input shaft 1 and output shaft 8 are determined by their respective synthetic torques, that is, by the electromagnetic torque of the servo clutch and the power torque or load torque on the two shafts 1 and 8 .

Embodiment 3
[0066] The structure of embodiment 3 of the servo clutch device is mostly the same as that of embodiment 1 or 2, the difference is: the first rotor 3 is replaced with A position / speed sensor 2, and the second rotor 4 is replaced with B The position / speed sensor 7, the A position / speed sensor 2 and the B position / speed sensor 7 are connected to the servo driver 6 after the difference calculator, or the two position and speed sensors are connected to the servo driver 6 containing the difference calculator. The position and speed signals obtained by the two sensors 2 and 7 are sent to the servo driver 6 as the relative position and speed signals of the first and second rotors 3 and 4 after difference calculation; The servo driver of the / position servo unit, the servo driver 6 has a control port connected with the clutch control unit 10 for the speed / position setting signal and the torque limit signal, and works in a speed / position servo mode with a torque limit value.
