Speed-adjustable magnetic eddy current shaft coupling

Abstract

The invention relates to a speed-adjustable magnetic eddy current coupling which comprises an input shaft connected with a motor and an output shaft connected with a load. A left conductor disk rotating synchronously with the input shaft is sleeved on the input shaft and can slide along the input shaft. The coupling further comprises a right conductor disk which is rotatably sleeved on the output shaft and can slide along the output shaft. A left magnetic disk and a right magnetic disk which are fixedly sleeved on the output shaft are arranged between the left conductor disk and the right conductor disk. A middle disk fixedly sleeved on the output shaft is connected between the left magnetic disk and the right magnetic disk. The left conductor disk, the left magnetic disc, the middle disk, the right magnetic disk and the right conductor disk are arranged in parallel. The left conductor disk, the middle disk and the right conductor disk rotate synchronously. The coupling further comprises an air gap regulating mechanism. The speed-adjustable magnetic eddy current coupling is stable, reliable and efficient, and is provided with the air gap regulating mechanism so as be capable of meeting requirements for increasing or reducing speed in working conditions.

Description

technical field [0001] The invention relates to a magnetic eddy current coupling. Background technique [0002] In real life, the drive shaft transmission system connected by a coupling is widely used. Almost industrial occasions and areas involving motor power transmission in life will use the drive shaft transmission technology of the coupling. At present, the couplings used in the mechanical field are mostly mechanical couplings and hydraulic couplings. The mechanical coupling is a rigid connection, and the mechanical force transmits the torque. During the installation process, due to the axial offset error, the load of the supporting original will be increased, and the radial offset error will produce a sudden change load and cause high equipment In addition, the rigid connection will also generate impact load at the moment of starting. The hydraulic coupler speed regulation is an inefficient speed regulation method, the speed regulation range is limited, the high-spee...

Problems solved by technology

However, due to the limitations of the product's own structure and technical solutions, there are still many deficiencies in the product's technical performance that need to be improved, mainly as follows: ① The coupling governor itself cannot automatically adjust the air gap spacing, and it needs to be equipped with related devices to realize the air gap spacing. Adjustment to complete the speed regulation function, the design of the corresponding actuator has a great influence on the performance of the product; ②The mechanical mechanism for adjusting the air gap spacing in the product has inherent technical requirements. For magnetic turntables that appear in pairs, the gap adjustment mechanism is mostly It has the characteristics of many mechanisms and unstable execution reliability. These characteristics affect the application of couplings in occasions with high requirements for speed regulation accuracy.
