Abstract

The invention discloses a liquid-cooling speed-regulating magnetic clutch for a ship, and relates to a magnetic clutch. The problems that an existing water-cooled magnetic clutch is poor in compensation performance, poor in vibration reduction performance and large in axial occupied space during non-contact torque transmission are solved. The cover shell is fixed to the side wall of a supporting plate, the permanent magnet disc assembly and the conductor disc assembly are both arranged in the cover shell, the permanent magnet disc assembly is arranged in the conductor disc assembly, the transmission shaft penetrates through the center of the support and enters the cover shell, the transmission shaft is sleeved with one permanent magnet disc, and the transmission shaft between an inner ringof the support and the transmission shaft is sleeved with a supporting bearing. A sleeve is connected to an inner ring of the support, the supporting bearing is installed between the transmission shaft and the sleeve, an air gap adjusting mechanism is used for adjusting an air gap between the permanent magnet disc assembly and the conductor disc assembly to achieve separation and reunion and adjust the rotating speed of the load end, and the inner wall of one supporting plate and the outer wall of the shell are each provided with at least one cooling mechanism. The cooling mechanism is used for cooling the two conductor discs. The liquid-cooling speed-regulating magnetic clutch is used for giving full play to the compensation and vibration isolation performance of magnetic transmission.

Description

technical field [0001] The invention relates to a magnetic clutch, in particular to a device which uses circulating liquid cooling medium to limit the temperature rise of the eddy current disk inside the magnetic clutch under the working state under the marine condition. Background technique [0002] The magnetic clutch is to use the interaction between the magnetic fields to realize the speed adjustment and clutch control of the load end equipment. It belongs to non-contact torque transmission and has the characteristics of easy installation and maintenance, vibration isolation and strong compensation ability. At present, its connection transmission in the industrial field , It is widely used in the speed regulation and energy saving system of pump unit / fan. [0003] The magnetic clutch is mainly composed of three parts: the permanent disk assembly, the conductor disk assembly and the control mechanism. The permanent disk is installed with magnetic steel with N and S poles ...
