Description

Assembly structure of coupling

The invention relates to an assembly structure of a coupling machine, in particular to a structure for simplifying the disassembly and assembly operation of the coupling machine, which can meet the requirements 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. When we want to adjust the air gap, we must first dismantle a large number of screws. In addition to time-consuming and labor-intensive, since the screw is a small and easily overlooked component, it is very likely that a lost accident will occur during the disassembly process, resulting in a conventional permanent magnet coupling machine. Difficulties in reassembly.

In addition, for the internal devices of the conventional permanent magnet coupling, such as most bearing structures, which are limited by the complicated design of the conventional permanent magnet coupling described above, the composition relationship between the devices is quite close, and it is often difficult to disassemble for replacement. Or maintenance. Therefore, when it is necessary to replace the bearing, the whole set of machinery must be transported back to the original factory, and the original factory-specific tools are used for the replacement work, which is time-consuming and labor-intensive, and is rather uneconomical.

It can be seen from this that the assembly structure of the conventional permanent magnet coupling machine still has disadvantages and needs to be improved.

To this end, the Applicant has developed the assembly structure of a coupling machine by taking into account 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 distance between the permanent magnet rotor 2 and the sleeve 5 is changed by superimposing the spacers 6 of different thicknesses and numbers. Since the sleeve 5 is fixed on the rotating shaft 4, the permanent magnet rotor 2 will The distance is changed with respect to the magnetically permeable rotor 1, so that the size of the air gap 3 can be easily adjusted without largely disassembling the machine.

The permanent magnet rotor 2, the gasket 6, and the sleeve 5 are locked by the screw 21. In practical applications, the spacer 6 can be designed to be semi-circular, for two pieces.
