Description
Technical Field
The utility model relates to the technical field of permanent magnet couplers, in particular to a multi-magnetic-circuit parallel eddy current synchronous composite coupler capable of overloading, asynchronously starting and synchronously running.
Background
Permanent magnet couplers, as non-mechanically coupled transmission devices, have been widely used in recent years due to their vibration damping, low centering requirements, and overload resistance characteristics. The moment transmission between the prime motor and the working machine can be realized by means of the magnetic induction principle of the permanent magnet and the vortex ring and the permanent magnet.
The permanent magnet synchronous coupler and the permanent magnet eddy current coupler which are widely applied in the market at present have the advantages, but have larger limitation on heavy load or load starting load due to respective transmission characteristics. The concrete points are as follows: the permanent magnet synchronous coupler can force the load rotating speed to be synchronous with the motor, the power and torque transmission efficiency is high, the transmission efficiency is 100%, but the starting capability is poor, and the step is volatile during overload, so that the permanent magnet of the coupler is demagnetized to cause the damage of the coupler. If the load needs to be started with load or a large rotational inertia load needs to be started, or the load fluctuation is large, in order to ensure reliable operation, the power margin of the coupler needs to be greatly forced, a technician has already made a test, when the design power margin is amplified to 3 times of rated load power during the load of an air compressor, the normal operation still cannot be ensured, the power margin is applied to heavy-load large rotational inertia equipment such as a ball mill, even when the power margin needs to be increased to 5 times, the start is very reluctant, the power margin needs to be increased to 8 to 10 times, and the efficient start can be realized; under the condition of product sizing, the larger the difference between the rotation speeds of the load and the motor is, the larger the transmitted torque is, so that the better loaded starting capability is provided, but simultaneously, the transmitted torque depends on the difference between the rotation speeds, when the difference between the rotation speeds is smaller, the transmitted torque is smaller, theoretically, the synchronous operation of the load and the motor cannot be realized, the limit is designed, the difference between the rotation speeds still needs to be kept at the level of 2% -3%, namely, the permanent magnet eddy current coupler cannot drive the load to synchronously rotate with the motor, and the power loss is more than 2% in the use process.

The utility model discloses a parallel eddy current synchronous composite coupler 10, which adopts a radial structure as a main body, wherein an inner rotor and an outer rotor are coaxial, and a synchronous set of one (or more) synchronous coupler structures and an eddy current set of one (or more) permanent magnet eddy current coupler structures are axially arranged, so that the eddy current synchronous composite coupler is formed. The synchronizing group and the vortex group are axially juxtaposed. When the synchronous set is started, the load rotating speed is zero, the slip is the largest, the eddy current set provides larger starting torque due to high slip, the slip is gradually reduced along with the increase of the load rotating speed until the synchronous set is close to the cut-in rotating speed, and then the synchronous set is gradually cut in to enter a synchronous running state. When the load fluctuates, the synchronous group has overload capacity in a certain range, and when the overload capacity does not exceed the designed maximum torque of the synchronous group, the synchronous group still operates synchronously, when the load fluctuation exceeds the maximum torque of the synchronous group, slip is generated, and the vortex group continues to provide torque generated by differential speed until the cut-in rotation speed of the synchronous group is recovered and the synchronous group acts to reenter synchronous operation.
The parallel eddy current synchronous composite coupler of the utility model is acted by the eddy current group during starting, has larger starting torque, and after entering a synchronous state, the eddy current group does not work because the rotating speed difference is zero, and does not generate power loss at the same time, so the transmission efficiency can still reach 100 percent during normal synchronous operation.
The utility model aims to overcome the respective disadvantages of the existing permanent magnet synchronous coupler and the existing permanent magnet eddy current coupler, and provides a coupler which not only can ensure the synchronous operation of a load and a motor, but also has strong starting overload capacity, and can keep the advantages of magnetic transmission vibration reduction, vibration resistance, low centering requirement and overload resistance.
In order to realize the adjustment among different operation states of asynchronous soft start, synchronous operation and soft stop, the permanent magnet soft starter is provided with an 'execution mechanism', and the 'execution mechanism' comprises a servo motor 13, a speed reducing mechanism 14, a screw rod pair 15 and a shifting fork 16. It is obvious from the figure that the structure of the 'actuating mechanism' is too simple, and in the process of driving the shifting fork 16 to reciprocate by the screw rod pair 15, the shifting fork 16 shakes due to unbalanced stress, which finally affects the stability and accuracy of the whole starter. For this reason, further improvements in the "actuator" are necessary.
As shown in fig. 12, the parallel eddy-current synchronous compound coupling 10 of the present invention further includes an actuator 500, and the actuator 500 is used to drive the inner rotor member 200 to reciprocate in the axial direction. The actuator 500 includes: the double-shaft output motor 510, a seat body 520, a transmission screw rod 530, a left reciprocating sleeve 540, a right reciprocating sleeve 550 and a shifting fork structure 560.
The transmission screw 530 is rotatably disposed on the base 520, and two ends of the dual-shaft output motor 510 are respectively connected with two ends of the transmission screw 530 through the left reduction gear set 511 and the right reduction gear set 512.
The inner rings of the left reciprocating sleeve 540 and the right reciprocating sleeve 550 are screwed on the rod body of the transmission screw rod 530, the left reciprocating sleeve 540 and the right reciprocating sleeve 550 are arranged at intervals, the left reciprocating sleeve 540 and the right reciprocating sleeve 550 are both provided with a guide projection 501, and the seat body 520 is provided with a guide groove 521 matched with the guide projection 501.
The fork structure 560 has a sleeve portion 561 having both ends screwed to the outer rings of the left and right reciprocating sleeves 540 and 550, and a connecting portion 562 connected to the inner rotor member 200.
The actuator 500 also includes two stabilization reinforcement structures 570. Two stabilizing and reinforcing structures 570 are mounted on the base 520 and connected to two ends of the driving screw 530, respectively.
The stabilization reinforcement structure 570 includes: a housing 571, an axial support bearing 572, a radial support bearing 573. The axial support bearing 572 and the radial support bearing 573 are housed in the housing 571, and the end of the drive screw 530 is connected to the axial support bearing 572 and the radial support bearing 573.
The operation principle of the actuator 500 is explained below:
two ends of the double-shaft output motor 510 respectively drive the transmission screw 530 to rotate through a left reduction gear set 511 and a right reduction gear set 512;
the rotating transmission screw 530 further drives the left reciprocating sleeve 540 and the right reciprocating sleeve 550 screwed on the rod body to move along the seat body 520; it is noted that the left and right reciprocating sleeves 540 and 550 can be moved synchronously in the same direction by adaptively adjusting the inner thread of the left and right reciprocating sleeves 540 and 550;
the dual-axis output motor 510 rotates forward or backward, i.e. the left reciprocating sleeve 540 and the right reciprocating sleeve 550 can reciprocate along the seat 520;
both ends of the sleeve portion 561 of the fork structure 560 are respectively screwed with the outer rings of the left reciprocating sleeve 540 and the right reciprocating sleeve 550, so that the left reciprocating sleeve 540 and the right reciprocating sleeve 550 can drive the sleeve portion 561 to reciprocate, and the sleeve portion 561 further drives the inner rotor member 200 to reciprocate through the connecting portion 562.
During the sudden start of the dual-axis output motor 510, the driving screw 530 is also accompanied by the sudden start, and the sudden start of the driving screw 530 generates a large impact inertia, which may cause the driving screw 530 to shake, and in a serious case, may cause the driving screw 530 to break and other components connected to the driving screw 530 to be damaged. In order to reduce the impact caused by the impact inertia, the actuator 500 of the present invention further includes two stabilizing reinforcing structures 570, and the two stabilizing reinforcing structures 570 are mounted on the seat 520 and are respectively connected to two ends of the driving screw 530.
At the moment when the drive screw 530 is suddenly started, the axial support bearing 572 and the radial support bearing 573 bear the impact force of the drive screw 530 in the axial direction and the radial direction, respectively, and the axial support bearing 572 and the radial support bearing 573 firmly hold the end of the drive screw 530.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
