Permanent-magnet transmission mechanism for stirring device

Abstract

The invention discloses a permanent-magnet transmission mechanism for a stirring device. The permanent-magnet transmission mechanism comprises a housing and a fixed base. A driving plate is connectedto the bottom of a motor shaft; and driving permanent magnet blocks are arranged at the two sides of the bottom at the inner side of the driving plate. A connection base is connected to the top of a damping spring. A fixed sleeve is connected to the bottom of the connection base; a first connection sleeve is connected to the top of the connection base; and ventilating slots are formed in the two sides inside the fixed base. A rotation blade is connected to the top of the outer side of a rotation rod. Electric push rods are connected to the two sides of the top of the fixed base; fixed plates are connected to the two sides of the housing; the tops of the electric push rods are connected with the bottoms of the fixed plates; and compression springs sleeve the outer sides of the electric pushrods. The permanent-magnet transmission mechanism has advantages of automatic heat dissipation and automatic and stable rotational speed controlling; and thus the permanent-magnet transmission mechanism is able to realize automatic cooling and automatic and stable rotation speed controlling.

Description

technical field [0001] The invention relates to the technical field of permanent magnet transmission, in particular to a permanent magnet transmission mechanism for stirring equipment. Background technique [0002] The permanent magnet transmission technology uses magnetic force to drive the load to achieve non-contact torque transmission between the motor and the load. The active rotor driven by the motor rotates at high speed, cutting the magnetic field lines in the magnetic field generated by the driven rotor, thereby generating an induced magnetic field. Through the magnetic field The interaction force between them drives the load to work and realizes the transmission of torque. [0003] At present, when the permanent magnet transmission technology is used to drive the stirring shaft in the stirring equipment to rotate, the function of the permanent magnet transmission mechanism is relatively simple, but it can simply stir the stirring equipment. The permanent magnet tra...
