Abstract
The utility model discloses a device changing rotation motion into reciprocating straight-line motion via magnetic field changes. Primarily, four permanent magnets with separate N, S arranged on a rotary bracket form a magnetic field with permanent magnets at both ends of two groups of spaced U-shaped drive rods in cross slots on a support tube. With the changes of the magnetic field, the two groups of U-shaped drive rods reciprocate in the cross slots, so that the drive rods and the drive tube are respectively driven to effectively use attraction force and repulsive force generated by the magnetic field to reach the purpose of labor saving. The utility model has the advantages of simple structure, reliable work, etc., and can be used in bicycles, motorcycles, automobiles, tractors and other machines.
Description
The invention belongs to magnetic drive device.
Mostly to be some moving with rotation motion to linear or the transhipment of straight line motion mutarotation is the device of purpose for existing magnetic drive device, and as CN1055089A and CN1082264 etc., it does not consider the efficient of start.
The purpose of this invention is to provide a kind of permanent magnet same sex of utilizing repels each other; principle of opposite sex attraction; obtain bigger attraction force in magnetic field and mutual expelling force with less magnetic shear power; make mutual expelling force become linear reciprocation straight line motion power with suction mutually; and this linear reciprocating motion power made full use of, stable transmission, simple in structure; overload protection ability, labour-saving magnetic drive device are arranged.
The technological scheme that the present invention intends taking is: a kind of magnetic drive device, form by permanent magnet (7) etc., it is characterized in that: runing rest (8) is cross, be intervally arranged in the end of cross by N.S permanent magnet and with NULL every magnetic, runing rest (8) by bearing fixing on support column (3), driving wheel (10) links to each other with runing rest (8), end at support column (3), have cross recess, reciprocal transmission tube (9) is installed in support column (3), back and forth an end of transmission tube (9) links to each other with a ∪ shape drive link (4), the other end links to each other with transmission part, the two ends of ∪ shape drive link (4) are equipped with the identical permanent magnet of polarity (7), permanent magnet (7) is equipped with NULL with the attachment portion of ∪ shape drive link (4), ∪ shape drive link (4) is stuck in the cross recess of support column (3), another ∪ shape drive link (2) is fixed on the reciprocal drive link (1) by set screw nut (13), back and forth drive link (1) is enclosed within the reciprocal transmission tube (9), this ∪ shape drive link (2) be fixed on ∪ shape drive link (4) on the reciprocal transmission tube (9) and be cross-shaped and be limited in the cross recess of support column (3), the two ends of ∪ shape drive link (2) also are equipped with the identical permanent magnet of polarity (7), this polarity is identical with permanent magnet (7) polarity at ∪ shape drive link (4) two ends, on the support column (3) between runing rest (8) and the ∪ shape drive link, be with spacing damping spring (6), on spacing damping spring, be with spill position-limiting tube (5), between support column (3) and reciprocal transmission tube (9), sliding sleeve (11) is housed, back and forth between transmission tube (9) and the reciprocal drive link (1) sliding sleeve (12) is being housed also, the distance between runing rest (8) and ∪ shape drive link (2) and (4) is regulated by the adjustment pad (14) that is enclosed within on the support column (3).
The present invention is in the changes of magnetic field process, with less magnetic shear power, bigger magnetic attraction and mutual expelling force have been obtained, and utilize reciprocal transmission tube (9) and back and forth drive link (1) is reciprocating in support column (3), suction and repulsion are become straight line motion power, runing rest (8) whenever rotates a circle, back and forth transmission tube (9) and reciprocal drive link (1) are with regard to each to-and-fro motion secondary, because the polarity of the permanent magnet on the runing rest (8) all is the N.S interphase distribution, ∪ shape drive link (2) is identical with permanent magnet polarity on (4), so runing rest (8) is when rotating, back and forth transmission tube (9) and reciprocal drive link (1) just do reciprocating linear motion under magnetic force in support column (3), this moment, reciprocal drive link (1) and reciprocal transmission tube (9) all were subjected to magnetic force in process or in backhaul, back and forth the suffered repulsion of transmission tube (9) hour, the reciprocal gravitation maximum that is subjected to of drive link (1), the reducing of repulsion are compensated by the increase of suction, and vice versa.If with reciprocal transmission tube (9) and back and forth drive link (1) be connected one when differing on 180 ° the bent axle; back and forth transmission promptly becomes and rotatablely moves; magnetic shear power become draw in magnetic field, repulsion; so just saved input power; made full use of magnetic field; can increase ouput force; and mechanical operation is steady; when mechanism transships; magnetic field energy can not change mechanical energy into, and when runing rest this moment (8) rotated, back and forth drive link (1) and reciprocal transmission tube (9) were not reciprocating; protect machinery like this, played overload protective function.
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the B-B place sectional view of Fig. 1.
Fig. 4 is that the A of Fig. 1 is to view.
Among the figure: 1 reciprocal drive link; 2 ∪ shape drive links; 3 support columns; 4 ∪ shape drive links; 5 limit spring; 6 spill position-limiting tubes; 7 permanent magnets; 8 runing rests; 9 reciprocal transmission tubes; 10 driving wheels; 11 sliding sleeves; 12 sliding sleeves; 13 set screw nuts; 14 pads.
In the present invention, be fixed on by bearing (among the figure mark) and be criss-cross runing rest (8) on the support column (3) and link to each other with driving wheel (10), driving wheel (10) can be a gear, belt pulley, it also can be friction wheel etc., when external force is ordered about driving wheel (10) rotation, runing rest (8) also rotates, the end of runing rest (8) is equipped with the alternate permanent magnet of N.S (7), link to each other with NULL heavy wall aluminum pipe between runing rest (8) and the permanent magnet (7), end at support column (3) has cross recess, ∪ shape drive link (2) and (4) are cross-shaped cross spacing in the cross recess of support column (3), ∪ shape drive link (4) is fixedly linked with reciprocal transmission tube (9), ∪ shape drive link (2) is fixedly linked by nut (13) with reciprocal drive link (1), back and forth transmission tube (9) is enclosed within the support column (3), back and forth drive link (1) is enclosed within the reciprocal transmission tube (9), in support column (1), back and forth between transmission tube (9) and the reciprocal drive link (1), sliding sleeve (11) and (12) are housed, to reduce friction respectively.Each end of ∪ shape drive link (2) and (4) is equipped with permanent magnet (7) and every magnetic, its polarity is identical, when runing rest (8) rotates, magnetic field between runing rest (8) and ∪ shape drive link (2) and (4) changes, when ∪ shape drive link (2) and runing rest (8) when repelling each other, ∪ shape drive link (2) drives reciprocal transmission tube (9) to left dislocation, this moment is along with the increase of displacement, back and forth the suffered repulsion of transmission tube (9) also reduces, meanwhile, ∪ shape drive link (4) takes place to inhale mutually with runing rest (8), ∪ shape drive link (4) drives reciprocal drive link (1) displacement to the right, and along with reducing of distance between the two, attraction force increases, vice versa, reached equilibrium of forces.Spill position-limiting tube (5), spacing damping spring (6) and adjust pad (14) and be enclosed within on the support column (3) between ∪ shape drive link (2) and (4) and the runing rest (8), it mainly acts on is the distance of regulating between the permanent magnet (7), and spacing with obtain best to draw, the repulsion proportioning.Be connected bent axle, eccentric wheel, ratchet mechanism, clutch etc. at reciprocal transmission tube (9) with the other end of reciprocal drive link (1), can effectively magnetic field energy be changed into mechanism's energy.
