Embodiment Construction

[0039] Such as Figure 1-8 Shown:

[0040] The invention adopts an outer single-ring induction device with a fixed radial air gap size, a radiation-oriented ring-type inner overall magnetic ring with an optimized structure for effective size and a high-efficiency heat dissipation system, supplemented by a static speed regulating mechanism. The non-contact torque transmission between the motor and the load is realized through magnetic coupling, and the high-efficiency heat dissipation is used to ensure the stability of the magnetic force of the system. Realize automatic slip protection for motor and load equipment when the load is overloaded. In the static state, the speed regulation of the load and the energy saving of the motor are realized through the meshing surface adjustment mechanism. The specific structure and technical scheme of the inner radiation ring type static speed-regulating permanent magnet coupling are as follows: 1 conductor outer rotor I: motor shaft expan...

Abstract

Provided is an internal radiation ring type static speed-adjusting permanent magnetic coupling. The internal radiation ring type static speed-adjusting permanent magnetic coupling is composed of a conductor outer rotor I, a permanent magnetic inner rotor II and a gearing face adjusting mechanism III, wherein the conductor outer rotor I is connected with a motor shaft (17) and a motor shaft key strip (18) through a motor shaft expansion sleeve to lead in motor power, the permanent magnetic inner rotor II is connected with a bearing shaft (19) and a bearing shaft key strip (20) through a bearing shaft expansion sleeve to output torque, and the gearing face adjusting mechanism III is adjusted in a manual mode to change the gearing area between the conductor outer rotor I and the permanent magnetic inner rotor II in a stationary state. The internal radiation ring type static speed-adjusting permanent magnetic coupling is characterized in that the conductor outer rotor I carries out high-speed rotation on an outer copper ring in a single circular ring inductor of the conductor outer rotor I so as to carry out radial fixation and air gap cutting on a magnetic force line of an internal radiation type integral magnetic ring of the permanent magnetic inner rotor II to produce eddy current on the outer copper ring, meanwhile, the eddy current produces an induced magnetic field, and the induced magnetic field and a permanent magnetic field are in interaction to achieve power connectionless transmission. Meanwhile, a high-efficiency heat dissipation device is used for reducing the temperature of the outer copper ring and the temperature of the internal radiation type integral magnetic ring, and stable operation of system magnetic force is ensured.

Description

technical field [0001] The invention relates to a motor coupling device, which is suitable for the connection between the motor and the load under the working condition that the motor starts frequently and the output of the load needs to be adjusted. Background technique [0002] Couplings are frequently used components in the power transmission process of mechanical systems, and are widely used in petrochemical, power industry, mining and shipping, aerospace, steel industry, papermaking and other industries. With the continuous development of science and technology, the application field of couplings has been continuously expanded, and the technology has also been continuously developed, and new products and technologies have emerged in an endless stream. [0003] There are many types of couplings, which are usually divided into rigid couplings and flexible couplings according to whether they have the ability to compensate for relative displacement, that is, whether they ca...
