Abstract

The invention relates to a magnetic nut and a universal permanent magnet transmission device. The universal permanent magnet transmission device comprises a motor, a lead screw, a nut, bearings and a bearing block. The lead screw is directly connected with an output shaft of the motor, the two ends of the lead screw are supported by the bearings, and the bearings are in sliding fit with the bearing block. The universal permanent magnet transmission device is characterized in that a plurality of protruding magnetic poles are distributed on the surface of an outer thread, opposite to the lead screw, of the magnetic nut, each magnetic pole is provided with a circular arc surface, the magnetic poles are distributed according to the directions of the N magnetic pole and the S magnetic pole in a staggered mode, the external diameter of the lead screw and the external diameter of the motor are smaller than the minimum diameter of the magnetic nut, the two ends of the lead screw at the corner are connected with universal couplers, and continuous conveying can be achieved through a conveying trolley via a bent path.

Description

technical field

[0001] The invention relates to the technical field of production line transmission and material conveyance, in particular to non-contact magnetic transmission and screw transmission technology, especially for continuous transmission devices used in equipment manufacturing and production lines. Background technique

[0002] The transmission of sliding screw and ball screw used in machine tools of equipment manufacturing industry can directly convert circular motion and linear motion, which is simple and efficient, and has been widely used in machine tools and equipment. However, the sliding screw and ball screw can only be used for linear transmission, without any curves and bends. The production line used for parts production and assembly often has straight lines and curves. Even if the local section of the production line is all straight, the length of its continuous transmission will greatly exceed the maximum processing length range of the screw. Since t...
