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
The present invention relates to a kind of magnetic drive device, especially relate to a kind of magnetic force helicoidal gear.
Background technique
Magnetic drives is owing to have not friction in the process of transmission; Do not need advantages such as oiling agent and some application have been arranged aspect mechanical transmission; Like magnetic-gear, magnetic coupling; But carry out also not having related developments aspect the linear reciprocating motion than heavy load realizing that the load linear reciprocating motion is particularly realized driving, people thirst for a kind of novel magnetic transmission device and solve the problem in the reality now.
Summary of the invention
The purpose of this invention is to provide a kind of magnetic force helicoidal gear, it can realize driving the purpose of carrying out linear reciprocating motion than heavy load.
The technical solution adopted for the present invention to solve the technical problems is: a kind of magnetic force helicoidal gear; Fixed magnet on the screw axis; Magnet on screw axis in the shape of a spiral shape arrange and constitute the magnetic screw rod, see that from the outer surface of magnetic screw rod two adjacent magnetic helixes are that the N utmost point and S are extremely alternate; Nut sleeve internal surface fixed magnet, magnet are arranged in the shape of a spiral in nut sleeve and are constituted the magnetic nut, see that from the internal surface of magnetic nut two adjacent magnetic helixes are that the N utmost point and S are extremely alternate; Has the gap between magnetic screw rod and the magnetic nut.
The invention has the beneficial effects as follows: realized driving and carried out the purpose of linear reciprocating motion, and do not had not friction, do not needed oiling agent, advantages such as stable and overload protection than heavy load.
Description of drawings
Fig. 1 is magnetic screw rod of the present invention and magnetic nut assembling schematic representation;
Fig. 2 is a schematic representation of having fixed the screw axis of magnet of the present invention;
Fig. 3 is a schematic representation of having fixed the nut sleeve of magnet of the present invention.
Among the figure: the 1-screw axis; 2-magnet; The 3-nut sleeve.
Embodiment
Below in conjunction with the detailed mode of execution of the present invention of accompanying drawing:
In Fig. 1, has the gap between magnetic screw rod and the magnetic nut.
In Fig. 2, fixed magnet 2 on the screw axis 1, and magnet 2 spiral on screw axis 1 is arranged, and sees from outer surface, and adjacent two its polarity of magnetic helix are that the N utmost point and S are extremely alternate.
In Fig. 3, nut sleeve 3 inboard fixed magnets 2, magnet 2 is arranged at nut sleeve 3 inboard spirals.See that from internal surface adjacent two its polarity of magnetic helix are that the N utmost point and S are extremely alternate.
In practical operation; When having fixed the screw axis 1 of magnet 2 and having fixed nut sleeve 3 assemblings of magnet 2; Screw axis 1 screws in the nut sleeve 3, and the S utmost point of the magnet 2 of the N utmost point of magnet 2 and nut sleeve 3 inboards attracts each other on the screw axis 1, and the N utmost point of the magnet 2 of the S utmost point of magnet 2 and nut sleeve 3 inboards attracts each other on the screw axis 1; When screw axis 1 rotates; Nut sleeve 3 is aided with under the effect of the constraint that prevents nut sleeve 3 rotations that adds under the influence of the interaction force between the magnet 2 on screw axis 1 and the nut sleeve 3 again, realizes the straight line motion of nut sleeve 3.When screw axis 1 counter-rotation, realize nut sleeve 3 reciprocal straight line motions.The constraint of wherein mentioning that prevents nut sleeve 3 rotations can be and screw axis 1 guide rail parallel and that be connected with nut sleeve 3.
The present invention is owing to the 3 inboard magnet 2 of nut sleeve in the process that realizes linear reciprocating motion have all been participated in the transmission of power, so the present invention can transmit bigger load.
The present invention does not need advantages such as oiling agent owing to have not friction, and the power of transmitting is bigger, is applicable to the equipment of producing medicine, food etc.
