Abstract
The utility model relates to an axial type magnetic shaft coupling, which comprises an inner rotor, an inner rotor magnet, a shielding can, an outer rotor and an outer rotor magnet, wherein the shielding can is a round cylinder whose one end is sealed, one end of an opening of the shielding can is provided with a flange, the inner rotor is arranged in an inner hole of the shielding can, the inner rotor magnet is installed on the external circle surface of the inner rotor, the outer rotor takes a drum shape, the outer rotor magnet is installed in the inner hole of the outer rotor, and the outer rotor is sleeved on the external circle surface of the shielding can through the outer rotor magnet. The shaft coupling of the utility model can realize static sealing between a driving shaft end and a driven shaft end, and a driving shaft and a driven shaft can cut off the driving connection when in surcharge load.
Description
Technical field
The utility model relates to a kind of shaft coupling, particularly magnetic shaft coupling.
Background technology
Shaft coupling is a kind of universal machine parts, by connecting mode positive coupling, flexible coupling is arranged, and these kind shaft couplings all adopt direct connecting mode to carry out transmission.They are at common defects: 1, initiatively can not realize standstill seal between axle head and the passive axle head.2, initiatively axle head connects by middleware with passive axle head, can not cut off the transmission contact during overload.
Summary of the invention
The purpose of this utility model provides a kind of axial type magnetic shaft coupling, and this axial type magnetic shaft coupling can be realized initiatively standstill seal between the axle head and passive axle head, and driving shaft and driven axle can cut off transmission and get in touch during overload.
The technical solution of the utility model is: a kind of axial type magnetic shaft coupling comprises internal rotor, inner rotor magnets, cage, external rotor and outer rotor magnet.Cage is the drum of end sealing, is provided with flange at cage opening one end; Internal rotor places the cage endoporus, and inner rotor magnets is installed on the periphery of internal rotor; External rotor is a drum shape, and outer rotor magnet is installed in the endoporus of external rotor, and external rotor is sleeved on the periphery of cage by outer rotor magnet.
Compared with prior art, in the utility model, the internal rotor assembly (driven axle) that is made of internal rotor and inner rotor magnets places the cage endoporus, the external rotor assembly (driving shaft) that is made of external rotor and outer rotor magnet places outside the cage, internal rotor assembly (driven axle) and external rotor assembly (driving shaft) are isolated by cage, utilize the magnetic field transfer torque, during overload, then enough moments of torsion can not be transmitted in magnetic field, and the transmission of driving shaft and driven axle is got in touch and can be cut off.Because cage is the fixture that does not rotate, can realize standstill seal again with body.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Parts label in the accompanying drawing is: 1 is internal rotor, and 2 is cage, and 3 is external rotor, and 4 is outer rotor magnet, and 5 is inner rotor magnets.
Embodiment
