Description

Permanent magnetic maglev linkage device

Technical field

The utility model relates to a mechanical linkage device, in particular to a permanent magnetic maglev linkage device, which is suitable for use in equipment requiring a relatively large rotational moment when a motor is used as power.

Background technique

In the prior art, many mechanical devices are powered by motors, and only couplings are often used as linkages between motors and equipment, but couplings have always had high assembly precision, complicated installation, high operating noise, and mechanical friction. Deficiencies such as energy loss. In addition, the current linkage device is not equipped with a device for increasing the rotational torque, so it is difficult to meet the requirements of some equipment, which is the shortcoming of the prior art.

Contents of the invention

The purpose of the utility model is to provide a permanent magnetic maglev linkage device with stable and reliable operation, relatively small transmission noise and mechanical wear, and can increase the rotational torque.

The above tasks are achieved in such a way: a permanent magnet maglev linkage device, which is characterized by a main motor, a driving wheel, a driven wheel, a power output shaft, a flywheel and an auxiliary wheel. The driving wheel is arranged on the main motor shaft. The power output shaft is coaxially placed in front of the shaft through the bearing support and the main motor shaft. The driven wheel is sleeved on the driving wheel and connected with the power output shaft. The flywheel is set on the power output shaft between the two bearings, under the flywheel There are at least no less than two auxiliary wheels, and several longitudinal permanent magnet blocks are evenly arranged on the outer circumference of the driving wheel, the inner circumference of the driven wheel, and the outer circumference of the flywheel and the auxiliary wheel. The polarity of the opposite surface of the permanent magnet block between the driving wheel and the permanent magnet block between the flywheel and the auxiliary wheel is the same, the rotation gap between the driving wheel and the driven wheel and the rotation gap between the flywheel and the auxiliary wheel Both are 0.5 to 1.5 mm.

The purpose of this utility model can also be achieved by issuing measures:

The cross-section of the permanent magnet blocks is suitable to be 10×10 mm to 15×15 mm, and the distance between two adjacent permanent magnet blocks should not be greater than their width.

An auxiliary motor is also arranged on the auxiliary wheel to facilitate the rotation and rotation of the flywheel more smoothly.

The working principle of the utility model is as follows: when in use, just connect the equipment with the power output shaft. After starting the main motor, the driving wheel drives the driven wheel to rotate through magnetic force, and outputs power through the equipment connected in the axial direction through the power output. At the same time, the rotation of the power output shaft also drives the flywheel to rotate, increasing the rotational torque of the output shaft. Since the driving wheel and the driven wheel work in a magnetic levitation state under the magnetic force of the opposite magnetic blocks of the same polarity, they do not touch each other, and the flywheel and the auxiliary wheel also rotate in a magnetic levitation state, so that the rotation of the flywheel will not affect the bearing. Excessive rotational pressure is generated, which greatly reduces the wear between the power output shaft and the bearing. Therefore, the running noise of the entire linkage device is very small, and the flywheel rotates very smoothly, which can generate a large rotational moment, so that the equipment connected with it can obtain sufficient power. In addition, the motor is installed on the auxiliary wheel. It is beneficial for the flywheel to start and rotate smoothly. Therefore, the utility model has the advantages of stable and reliable operation, low noise, relatively large rotational torque, etc., and effectively overcomes the deficiencies of the prior art. The utility model is particularly suitable for equipment requiring low noise and large output torque.
