Embodiment Construction

[0014] In order to enable those skilled in the art to better understand the technical solution of the present invention, the application will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the application. .

[0015] Such as figure 1 Shown is a schematic diagram of the first embodiment of the present application, including a drive disc assembly 10 and a pulley assembly 20, the pulley assembly 20 is provided with a coil assembly 40, and the drive disc assembly 10 or Several permanent magnets 30 are evenly distributed on the pulley assembly 20; the magnetic attraction force of the permanent magnets 30 is transmitted between the drive disk assembly 10 and the pulley assembly 20, so that the first drive disk assembly 10 adjacently arranged The friction surface 11 is engaged with the second friction surface 21 of the pulley...

Abstract

The invention provides an electromagnetic clutch. The electromagnetic clutch comprises a driving disc assembly and a belt wheel assembly, a coil assembly is arranged on the belt wheel assembly, and aplurality of permanent magnets are arranged on the driving disc assembly or the belt wheel assembly; the magnetic attraction force of the permanent magnets is transmitted between the driving disc assembly and the belt wheel assembly, so that the first friction surface of the driving disc assembly and the second friction surface of the belt wheel assembly which are adjacently arranged are attracted, and the clutch is attracted to work; and when the coil assembly is electrified, reverse electromagnetic force generated by the coil is counteracted with magnetic attraction force of the permanent magnets, so that the first friction surface is separated from the second friction surface, and the clutch is disconnected. The electromagnetic clutch has the beneficial effects that when the coil assembly is not electrified, the clutch is always in an attraction working state; when the coil assembly is powered on, magnetic attraction force of attraction of the clutch is counteracted by reverse electromagnetic force generated by power-on of the coil assembly, and the clutch is disengaged and disconnected; and thus, a normally-closed electromagnetic clutch is formed, clutch attraction work can beachieved without energy consumption, the structure is simple, and energy is saved.

Description

technical field [0001] The present disclosure relates to the technical field of electromagnetic clutches, in particular to an electromagnetic clutch. Background technique [0002] Electromagnetic clutch, also known as electromagnetic coupling, uses the principle of electromagnetic induction and the friction between the inner and outer friction plates to make the two rotating parts in the mechanical transmission system, and the driven part does not stop rotating when the active part does not stop rotating. An electromechanical connector that can be combined or separated from it, is an electrical appliance that performs automatically. Electromagnetic clutches can be used to control mechanical starting, reverse, speed regulation and braking, etc. It has the advantages of simple structure, fast action, small control energy, and convenient long-distance control; however, the electromagnetic clutch is small in size and can transmit large torque; when used for braking control, it ...
