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 drive disk assembly, by connecting mode, has positive coupling, flexible coupling, and these kind shaft couplings all adopt direct connecting mode to carry out transmission.They are at common defects: 1, initiatively between axle head and passive axle head, can not realize standstill seal.2, initiatively axle head connects by middleware with passive axle head, can not cut off transmission contact during overload.
Summary of the invention
The purpose of this utility model is to provide a kind of radial magnetic shaft coupling, and this radial magnetic shaft coupling can be realized initiatively standstill seal between axle head and passive axle head, and during overload, driving shaft and driven axle can cut off transmission and contact.
The technical solution of the utility model is: a kind of radial magnetic shaft coupling, comprises driving shaft, drive end half a coupler, magnet, cage, driven end half a coupler and driven shaft.Cage is the drum type of one end sealing other end opening, driven shaft is positioned at the inner side of cage, driven shaft is equipped with driven end half a coupler near cage one end, the end of driven end half a coupler is flange, the end face of this flange is radially provided with magnet, magnet divides the S utmost point, the N utmost point alternately, and the end face of this flange and cage keep certain interval; Driving shaft is positioned at the outside of cage, driving shaft axle is equipped with drive end half a coupler near cage one end, and the end of drive end half a coupler is flange, and the end face of this flange is radially provided with magnet, magnet divides the S utmost point, the N utmost point alternately, and the end face of this flange and cage keep certain interval.
During work, driving shaft rotarily drives the rotation of drive end half a coupler, and drive end half a coupler upper flange end face attraction driven end half a coupler upper flange end face magnet rotates thereupon, thereby drives driven shaft rotation, reaches powerdriven object.
Compared with prior art, in the utility model, magnet is radially distributed in end face of flange, simple in structure easy for installation; Driven end half a coupler is placed in cage endoporus, drive end half a coupler is placed in outside cage, driven end half a coupler and drive end half a coupler are isolated cover isolation, utilize magnetic field transmitting torque, during overload, enough moments of torsion can not be transmitted in magnetic field, and the transmission of driving shaft and driven axle contacts and can be cut off.Because cage is the fixture not rotating, can realize standstill seal with body again.
