Description

Single tray type permanent magnet eddy current coupling that a kind of end face is fixing
Technical field
The invention belongs to permanent-magnet eddy current drive technology field, particularly relate to single tray type permanent magnet eddy current coupling that a kind of end face is fixing.
Background technology
The basic functional principle of permanent-magnet eddy current drive technology is: when permanent magnet rotor and ring of eddy rotor is for the relative rotation move time, the permanent magnet that in permanent magnet rotor, pole orientation is alternately arranged can produce alternating magnetic field in the ring of eddy be made up of electric conducting material, and then generate the eddy current of alternation within it, this eddy current produces Induced magnetic field again in ring of eddy, stationary magnetic field in Induced magnetic field and permanent magnet rotor interacts, just between two rotors, produce coupling torque, thus reach the effect of transmitting motion and moment of torsion.The version of permanent magnetic vortex drive device mainly contains socket type peace dish-type two kinds at present, and its application mainly comprises permanent magnet eddy current coupling (driver) and permanent-magnet eddy current speed regulator.Wherein tray type permanent magnet eddy current coupling, comprise single tray type and two tray type, have that axial arrangement is little, weight is light, it is little to vibrate, permanent magnetic material efficiency is high, eddy current loss is little, anti-jamming, the design feature such as de-coupling automatically, application of succeeding in workplaces such as requiring flexible startup, blocking rotation, limit torque and damping vibration-isolating.
But, existing permanent-magnet eddy current transmission patented technology, generally pay close attention to not to the positioning connection of permanent magnet rotor and ring of eddy rotor, existing tray type permanent magnet eddy current coupling product, normally to adopt one of the following two kinds mode to realize two rotors and installs location: a kind of is utilized by rotor block connecting bushing to be directly sleeved on the drive shaft of prime mover or load; Another kind arranges special support to be supported respectively by two rotors, and recycling joint member, couples together prime mover and the drive shaft of load and the rotating shaft of two rotors.All there is obvious deficiency in these two kinds of connected modes: front a kind of connected mode is by weight all for rotor and the stressed drive shaft all directly putting on prime mover or load, especially there is larger radial forces when directly installing belt pulley or gear, considerably increase the stressed of prime mover or load drive shaft spring bearing, thus cause the severe of its working condition, the increase of vibrating noise, the reduction of useful working life; Rear a kind of connected mode is owing to adding one or two cover supports, make prime mover, between load and support, ensure that the concentric locating of rotating shaft is more difficult, bring very big inconvenience to installation exercise, also give during system cloud gray model simultaneously and bring more exciting source and uncertain adverse factor.Therefore, develop more rational permanent magnet eddy current coupling positioning connection structure, there is the clear and definite market demand.
