Description
Technical field
The utility model belongs to the mechanical transmissioning technology field, is specifically related to magnetic drive and arrangement of clutch.
Background technology
Shaft coupling and clutch are links commonly used in the machine driving, and its function is a transfer torque between driving shaft and driven shaft, can improve the dynamics of drive system.Clutch is controlled between driving shaft and driven shaft in addition in conjunction with, the effect that separates.
The shaft coupling of magnetic drive generally is to be separately installed with permanent magnet at driving shaft and driven shaft two parts, by the magneticaction transfer torque between two-part permanent magnet.Existing magnetic drive shaft coupling is magnet rotor and outer magnet rotor in particularly the permanent magnet clutch of high pulling torque all is provided with slightly, constitutes the alternately arrangement of tile shape magnets N, the S utmost point by the permanent magnet of even number tile shape.This structure causes having only the magnetic force between the concave profile of magnet of outer arcuate face on the interior magnet rotor and the magnet on the external rotor that rotation has been dragged contribution, and the producible magnetic force in the magnet back side is to the not contribution of transmission of moment of torsion.
Traditional mechanical clutch is under the effect of external force, and by the frictional force transferring power on the contact-making surface between active part and the secondary part, otherwise separated when two parts, then the two is in the motion state of oneself separately, and is irrelevant mutually.Because traditional mechanical clutch is that frictionally carries out power transmission, active part combine with secondary part or separating process in, just half-clutch state, or the state of overload operation must have the phenomenon existence of sliding friction.Fricting movement will inevitably produce wearing and tearing, and the heat that is produced that in addition rubs causes part high temperature, and the friction plate quality is run down, even often has the damage phenomenon to take place.
Existing Permanent Magnet Clutch, agent structure is similar to permanent magnet clutch, utilize magnetic force transfer of torque between the permanent magnet at its bonding state, its transfer of torque value can be set, the torque value that is transmitted can not surpass this setting thresholding, otherwise understand slippage and be in the slippage motion state, under this slippage state, still keep the constant torque that drags, promptly with this torque value transmission power, and do not possess that clear and definite active part that conventional clutch has separates fully with secondary part and the state that do not transmit power, thereby can only be applied to the less transfer of torque that needs the special occasions of limit value is arranged.
Summary of the invention
