Combination adjustment structure of coupling

This creation is about a combination adjustment structure of the coupling machine, especially a structure that simplifies the assembly and disassembly operation of the coupling machine, and can meet the needs of the user to easily adjust the structure of the coupling machine and reduce the work complexity.

Generally, the permanent magnet coupling machine is mainly composed of a magnetic conductive rotor made of copper or aluminum and a permanent magnet rotor with a strong magnet. The magnetically permeable rotor is mainly fixed on the motor shaft, and the permanent magnet rotor is fixed on the load shaft, and there is a gap (commonly referred to as an air gap) between the magnetic permeable rotor and the permanent magnet rotor. In this way, the connection between the motor and the load is converted from a soft (mechanical) connection to a soft (magnetic) connection. By adjusting the air gap between the magnetically permeable rotor and the permanent magnet rotor, the output torque variation on the load shaft can be achieved. The load speed changes.

The permanent magnet coupling function can significantly improve the operating characteristics of the system. The permanent magnet coupling drive motor is started at no load before starting the load, which not only reduces the starting current of the motor and reduces the thermal shock load on the motor and the influence on the power system. Thereby saving electric energy and prolonging the working life of the motor, and extremely effectively reducing the destructive tension of the transmission system on the conveyor belt during startup, eliminating the shock generated when the conveyor is started, and greatly reducing the start of the transmission system itself. Shock, extended belts, idlers and other critical lifespans have improved the safe and reliable operation of the equipment, effectively reducing equipment maintenance and downtime costs. Therefore, compared with the traditional coupling machine, the permanent magnet coupling machine does provide a more advanced structure, which is extremely practical.

However, the structure of the conventional permanent magnet coupling machine still has shortcomings to be improved in practical applications. For example, when adjusting the air gap, it is often impossible to perform smoothly, and it takes a lot of manpower and time. The main problem is that the conventional permanent magnet couplings are mostly large mechanical structures, and their constituent units are quite complicated, especially the number of screws used in the assembly of the magnetically permeable rotor is even more amazing. When we want to adjust the air gap, we must first disassemble the components of the magnetic rotor. At this time, it is often necessary to disassemble a large number of screws. Since the screws are small and easily overlooked components, it is very likely that a lost accident may occur during the disassembly process. This causes difficulties in the reassembly of conventional permanent magnet couplings.

It can be seen that the combined adjustment structure of the conventional permanent magnet coupling still has disadvantages and needs to be improved.

To this end, the Applicant has developed a combination adjustment structure of the coupling machine in view of the problems arising from the above-mentioned conventional structure, adhering to the spirit of research innovation and excellence, and using its professional vision and professional knowledge.

The main purpose of this creation is to provide a combined adjustment structure of the coupling machine, which can quickly and easily complete the combination and fine adjustment work of the magnetically permeable rotor, and does not need to disassemble a large number of screws, thereby simplifying the adjustment process.

Another object of the present invention is to provide a combined adjustment structure of a coupling machine which can prevent the screw from falling or missing, increase work efficiency and reduce maintenance costs.

In order to achieve the above object, the present invention adopts the following technical solution: a combined adjustment structure of a coupling machine, comprising a magnetically permeable rotor and a permanent magnet rotor, wherein the magnetically permeable rotor and the permanent magnet rotor are magnetically coupled and rotated simultaneously, the magnetically permeable rotor The utility model comprises a second turntable, wherein the two turntables are combined by a plurality of adjusting units, and the adjusting unit can rotate and fine-tune the two The distance between the turntables; the axis of the magnetic rotor is provided with a positioning block, the positioning block is fixed on one of the turntables, the positioning block locks the inherent rotating shaft portion, and a plurality of locking screws are arranged around the rotating shaft portion, the rotating shaft portion A spacer is interposed between the positioning block, and a plurality of locking screws are disposed around the rotating shaft portion, so that the locking screw passes through the spacer to adjust a distance between the rotating shaft portion and the positioning block. .

The axis of the magnetically permeable rotor 1 is provided with a positioning block 13 fixed in the positioning block 13 On a turntable 11, the positioning block 13 locks the intrinsic shaft portion 14, and a spacer 3 is interposed between the shaft portion 14 and the positioning block 13 to finely adjust the distance of the shaft portion 14 with respect to the turntables 10, 11.

Therefore, when the coupling machine needs to adjust the air gap, the distance between the two rotating discs 10, 11 must be adjusted, but when the rotating disc 11 is moved, the positioning block 13 positioned on the rotating disc 11 is inevitably affected. And the position of the rotating shaft portion 14, so the positioning block 13 and the rotating shaft portion 14 must be removed. After the adjusting of the rotating plate 11 is completed, the distance between the positioning block 13 and the rotating shaft portion 14 is simultaneously adjusted and installed to complete the air gap adjustment. .

When the user needs to adjust the distance between the two rotary discs 10, 11, the nut 124 is first released (no need to be removed), and then the adjusting rod 122 is rotated to adjust the screw 123 based on the positioning rod 121. The distance is adjusted, and the adjusting rod 122 is pushed to relatively move the two rotating wheels 10, 11 to adjust the distance, and then the nut 124 is re-locked to complete the air gap adjusting work between the two rotating disks 10, 11.

During the operation, the user loosens all the nuts 124 around the magnetically permeable rotor 1, and then selects a small amount of the adjusting unit 12 to adjust the upper, middle and lower positions of the magnetically permeable rotor 1, when the adjusting unit 12 is small.
