Turnover type track magnetic attraction wheel

Abstract

The invention discloses a turnover type track magnetic attraction wheel. The metal track with the perimeter smaller than that of the inner circle of the non-magnetic stator is formed by connecting N identical steel buckling strips, a door arch force bearing structure is formed on the outer edge of the metal track and the attached section of the inner circle wall of the stator, and the inner edge of the metal track is attracted by an outer circle magnetic pole of the annular planetary permanent magnet, so that counter-acting force is generated on the annular planetary permanent magnet due to attraction of the metal track to form planetary rotation of the annular planetary permanent magnet. The planet carrier and the output shaft are driven to rotate and output. The steel buckle strips of the crawler belt enter the magnetic pole surfaces of the planar permanent magnets which repel the outer circular magnetic poles of the circular planetary permanent magnets one by one under a resistance-free state by utilizing a magnetic force difference; and the interlinked parallel motion is not affected by magnetic acting force in the parallel direction, and is separated from a permanent magnetic field in a resistance-free state and then enters a rotation cycle in a magnetic field attracted by an outer circle magnetic pole of the ring planet permanent magnet. The device is large in transmission torque, small in transmission loss, good in transmission synchronism and high in output efficiency, and can be widely applied to power-assisted transmission of various machines and power equipment.

Description

Technical Field

[0001] The invention relates to a permanent magnet power transmission device. Background Art

[0002] As is well known, the polarity of the permanent magnet poles is fixed and unchanging. The interaction between the magnetic fields of the permanent magnets and the inherent mutual repulsion or attraction magnetic force cannot be alternating at any time without the application of an electromagnetic field and external force. As a result, existing permanent magnet transmission products, while having the advantages of non-contact transmission, such as mechanical losslessness and noiselessness, still have defects such as low transmission torque, large transmission loss, and transmission step loss. In order to enable the magnetic force between the magnetic fields of the permanent magnets to be alternating at any time without the application of an electromagnetic field and external force, and to eliminate the defects of existing permanent magnet transmission products such as low transmission torque, large transmission loss, and transmission step loss, the present invention provides a revolving crawler magnetic attraction wheel. The magnetic field of each pole of the permanent magnet in the permanent magnet transmission device can change the repulsion or attraction magnetic force on the magnetized object at any time without the application of an electromagnetic field and external force. It has a large transmission torque, low transmission loss, good transmission synchronization, and high output efficiency. Summary of the Invention

[0003] The technical solution adopted by the present invention to solve its technical problems is: a revolving crawler magnetic wheel, including a gear ring, a planetary gear, a planetary carrier and accessories, characterized in that: the gear ring is made of non-magnetic material, its inner circular wall is provided with an anti-slip groove, and its two ends are provided with the inner edge of the stator with a limiting rib whose inner diameter is smaller than the inner circular wall diameter; the planetary gear is a radially magnetized annular planetary permanent magnet with a planetary magnetic isolation ring concentrically fixed on the outer edge magnetic pole surface, and performs planetary rotation along the inner circular wall of the stator; the accessories are multiple identical steel buckle strips with a length greater than the width of the annular permanent magnet and less than the inner width of the limiting rib, and its circumference is less than the circumference of the inner circular wall of the stator. The annular metal track is long, has a maximum inward curvature as a plane, and its inner edge is supported by the planetary magnetic isolation ring and the top wheel, the outer edge of the arc surface between the magnetic isolation ring and the top wheel is in contact with the inner circular wall of the stator, and both sides of the plane section between the magnetic isolation ring and the top wheel are in contact with the outer edge plane of the load-bearing track with a maximum inward curvature as a plane; the planetary carrier is fixed with a square permanent magnet whose plane magnetic poles produce a repulsive magnetic effect on the outer arc surface magnetic poles of the circular ring planetary permanent magnet and at the same time produce an attractive magnetic effect on the outer edge plane of the annular metal track, and the attractive magnetic effect spacing is less than the thickness of the planetary magnetic isolation ring, and supports the rotation of the circular ring planetary permanent magnet and the top wheel as well as the supporting roller for supporting the rotation of the load-bearing track. In this scheme, the metal track at the junction of the arc section and the plane section is changed from being attracted by the outer magnetic poles of the ring planetary permanent magnet to being repelled by it, and its steel buckle strips enter the plane section attracted by the square permanent magnet one by one from the arc section; the steel buckle strips of the track at the junction of the plane section and the arc section on the top wheel side are continuously moved away from the parallel upward magnetic force and are separated from the magnetic field one by one from the parallel section to the small arc section on the top wheel side; the steel buckle strips that fit the inner circular wall of the stator one by one form a gate arch load-bearing structure, which reacts on the attractive magnetic force of the outer arc poles of the ring planetary permanent magnet, pulls the ring planetary permanent magnet to rotate as a planet, and drives the planetary carrier and the output shaft to rotate, thereby forming a cyclic switching movement of each steel buckle strip of the track from being separated from the permanent magnetic field to entering the magnetic field one by one to generate the magnetic effect.

[0004] The beneficial effects of the present invention are as follows: the magnetic field of each pole permanent magnet in the permanent magnet transmission device can change the repulsive or attractive magnetic force on the magnetized object at any time without applying an electromagnetic field and external force to it, and it has large transmission torque, small transmission loss, good transmission synchronization and high output efficiency.

DETAILED DESCRIPTION

[0008] The stator (3) is made of stainless steel, and its inner wall (9) has an anti-slip groove, and its two ends have a limit rib (13) with an inner diameter smaller than the diameter of the inner wall (9). The ring planet permanent magnet (5) is radially magnetized, and a planetary magnetic isolation ring (12) is concentrically fixed on its outer edge magnetic pole surface, and it rotates along the inner wall (9) of the stator (3) in a planetary manner. The annular metal crawler is formed by linking a plurality of identical steel buckle strips (2) whose length is greater than the width of the circular planetary permanent magnet (5) and less than the inner width of the limiting retaining edge (13). The circumference of the annular metal crawler is less than the circumference of the inner circular wall (9) of the stator. The inner edge of the annular metal crawler is supported by the planetary magnetic isolation ring (12) and the top wheel (8). The outer edge arc surface between the magnetic isolation ring and the top wheel is fitted with the inner circular wall (9) of the stator (3) to form a gate arch load-bearing structure. The end face thereof is restricted to move on a plane by the limiting retaining edge (13). The plane section between the planetary magnetic isolation ring (12) and the top wheel (8) is fitted with the outer edge plane of the load-bearing crawler (11) whose maximum inward curvature is a plane on both sides. The circular planetary permanent magnet (5) and the top wheel (8) as well as the supporting roller (10) that supports the rotation of the load-bearing crawler (11) are supported and rotated by the planetary frame. The square permanent magnet (7) fixed to the planetary frame has a plane magnetic pole that produces a repulsive magnetic effect on the outer arc surface magnetic pole of the ring planetary permanent magnet (5), and at the same time produces an attractive magnetic effect on the outer edge plane of the annular metal crawler, and the attractive magnetic effect spacing (4) is less than the thickness of the planetary magnetic isolation ring. Alternatively, the width or thickness of the square permanent magnet (7) is set to be greater than the width or thickness of the ring planetary permanent magnet (5) to increase the magnetic effect of the square permanent magnet (7) on the metal crawler. In this scheme, the magnetized object in the same polar magnetic field is in a magnetic effect state of either attraction or repulsion. The metal crawler at the junction of the arc segment and the plane segment is transformed from the attractive magnetic effect of the outer magnetic pole of the ring planetary permanent magnet to the repulsive magnetic effect thereof, and its steel buckle strips can enter the plane segment attracted by the square permanent magnet (7) one by one in a free state from the arc segment. The outer edge of the load-bearing crawler (11) supports the rotation of the annular crawler plane section so that the square permanent magnet (7) maintains a consistent distance (4) between the steel buckle strips of the plane section and the curved surface section on the top wheel side and the flat section. The continuous movement of the crawler steel buckle strips at the junction of the curved surface section and the flat section is not affected by the magnetic force in the parallel direction. In a free state, the crawler steel buckle strips can enter the small curved surface section on the top wheel (8) side from the parallel section one by one and escape from the magnetic field of the square permanent magnet (7). The steel buckle strips that are fitted one by one with the inner circular wall (9) of the stator form a gate arch load-bearing structure. When the planetary magnetic isolation ring (12) and the top wheel (8) are clamped at the fitting point, a reverse force is formed to the attractive magnetic force generated by the outer arc surface magnetic pole of the ring planetary permanent magnet (9), which pulls the ring planetary permanent magnet (9) to make a planetary rotation, drives the planetary frame and the output shaft (1) to rotate, and then forms a cyclic switching change movement of each steel buckle strip (2) of the crawler from being separated from the permanent magnetic field to being entered into the permanent magnetic field one by one to generate magnetic action.An attached top wheel (6) is eccentrically mounted on the axle fixed to the planet carrier and supporting the rotation of the annular planetary permanent magnet to form a support for both ends of the annular metal crawler, so as to strengthen the arch bearing structure of the annular metal crawler and reduce the mechanical resistance when the annular planetary permanent magnet rotates. A different polarity magnetic pole (14) with a plane magnetic pole opposite to the plane magnetic pole of the square permanent magnet (7) is arranged on the top wheel (8) side of the square permanent magnet (7) to change the residual magnetic polarity of the rear section of the annular metal crawler, thereby increasing the attractive magnetic force of the annular planetary permanent magnet (5) on the annular metal crawler and the torque of the output shaft (1).

Claims

1. A revolving track magnetic wheel. A metal track with a circumference smaller than the inner circumference of a non-magnetic stator is constructed by linking N identical steel buckle strips. The outer edge of the track forms a gate arch load-bearing structure where it abuts the inner wall of the stator. Its inner edge is attracted by the outer magnetic poles of the ring planetary permanent magnets, generating a reaction force on the ring planetary permanent magnets, causing the magnets to rotate and drive the planetary carrier and output shaft for output.
