Problems solved by technology

[0002] Due to the advantages of no friction and no need for lubricants in the transmission process, magnetic transmission has some applications in mechanical transmission, such as magnetic gears and magnetic couplings, but it is relatively large in realizing reciprocating linear motion of loads, especially in driving There is no relevant progress in the reciprocating linear motion of the load, and now people are eager for a new type of magnetic drive to solve the real problem

Embodiment approach

[0011] exist figure 1 , there is a gap between the magnetic screw and the magnetic nut.

[0012] exist figure 2 Among them, a magnet 2 is fixed on the screw shaft 1, and the magnets 2 are helically arranged on the screw shaft 1. Seen from the outer surface, the polarities of two adjacent magnetic helical lines are N pole and S pole alternately.

[0013] exist image 3 Among them, the inner side of the nut sleeve 3 fixes the magnet 2, and the magnet 2 is helically arranged inside the nut sleeve 3. Viewed from the inner surface, the polarity of the two adjacent magnetic helical wires is alternate between N pole and S pole.

[0014] In actual operation, when the screw shaft 1 on which the magnet 2 is fixed and the nut sleeve 3 on which the magnet 2 is fixed are assembled, the screw shaft 1 is screwed into the nut sleeve 3, and the N pole of the magnet 2 on the screw shaft 1 is in contact with the inner pole of the nut sleeve 3. The S poles of the magnet 2 attract each other,...

Abstract

The invention relates to a magnetic driving device, in particular to a magnetic screw driving device. According to the magnetic screw driving device, magnets are fixedly arranged on a screw shaft and are spirally distributed on the screw shaft to form a magnetic screw; seem from an outer surface of the magnetic screw, two adjacent magnetic spiral lines are arranged in an N pole and S pole alternating manner; another magnets are fixedly arranged on the inner surface of a nut sleeve and are spirally distributed on the nut sleeve to form a magnetic nut; and seen from an inner surface of the magnetic nut, two adjacent magnetic spiral lines are arranged in an N pole and S pole alternating manner. The magnetic screw driving device has the advantages of no friction or lubricating agent, stability in operation, overload protection and the like.

Description

technical field [0001] The invention relates to a magnetic force transmission device, in particular to a magnetic force screw transmission device. Background technique [0002] Due to the advantages of no friction and no need for lubricants in the transmission process, magnetic transmission has some applications in mechanical transmission, such as magnetic gears and magnetic couplings, but it is relatively large in realizing reciprocating linear motion of loads, especially in driving There is no relevant progress in the reciprocating linear motion of the load, and now people are eager for a new type of magnetic drive to solve the real problem. Contents of the invention [0003] The object of the present invention is to provide a magnetic screw transmission device, which can realize the purpose of driving a relatively large load for reciprocating linear motion. [0004] The technical scheme adopted by the present invention to solve the technical problem is: a magnetic scre...
