Abstract
The invention relates to a support mechanism for an input shaft/output shaft of a magnetic coupler. The support mechanism is arranged on the input shaft/output shaft and comprises a bearing for supporting the input shaft, wherein a needle bearing which is connected to the inner end of the output shaft is arranged at the inner end of the input shaft. In the support mechanism provided by the invention, the needle bearing is arranged at the inner end of the input shaft and is served as a moveable fulcrum of the output shaft, and the other fulcrum of the output shaft is served as a fixed end which is mounted in a worm-gear box bearing base, thereby greatly promoting the rigidity and the strength of the output shaft.
Description
Technical field
The present invention relates to a kind of transmission device, relate to a kind of magnetic force coupling input axial organ specifically.
Background technology
The operation principle of magnetic coupling is followed the Coulomb's law of magnetic, i.e. two magnets separated by a distance, because magnetic field induction effect, they are without any need for traditional mechanical means, bonding force by magnet, just can be delivered to the another one magnet to power from a magnet, constitute a noncontact transfer torque mechanism.
Magnetic coupling is divided into conductor rotor that links to each other with prime mover and the magnet rotor two parts that link to each other with load, adjusts the output torque by the gap of adjusting between conductor rotor and the magnet rotor (air gap), thereby realizes speed governing.
There is following defective in above-mentioned magnetic coupling: existing output shaft structure is an overhanging beam, its outer end is connected on the stator by bearing, inner unsettled, this kind structure causes projecting shaft rigidity relatively poor, in use bend easily even rupture, influence the serviceability of coupler, cause potential safety hazard.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of output shaft magnetic coupling power shaft in useful life, output shaft supporting device of improving.
Technical scheme of the present invention is: the present invention is arranged on power shaft, the output shaft, comprises the bearing that supports power shaft, and power shaft the inner is provided with and the inner needle bearing that is connected of output shaft.
Power shaft the inner is provided with inner headed face, and described needle bearing is arranged in the inner headed face.
Advantage of the present invention is: the present invention establishes needle bearing in the inner of power shaft, and makes it a moving fulcrum as output shaft, and another fulcrum of output shaft is a stiff end, is contained in the worm gear case bearing pedestal, and the rigidity of output shaft, intensity are improved greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention
