Description
Technical field
The present invention relates to a kind of shaft coupling.Be particularly related to a kind of permanent magnet clutch.
Background technology
In the existing mechanical drive system, great majority adopt the mechanical attachment mode of rigidity, for example various machenical couplings between motor and the load equipment.Mechanical attachment is transmitted the vibration between motor and the load equipment mutually, amplifies the influence of vibration, makes drive system be easy to break down; When fault took place, because the effect of machenical coupling, the generation source of easy-to-search analysis of failure was not unfavorable for maintenance work; Especially when load equipment generation stall fault, the damage that will produce motor or transmission mechanism.In addition, centering required height when positive coupling was installed, and generally required coaxiality error ≯ 0.05mm, and some high-precision transmission system then requires coaxiality error ≯ 0.02mm, and installation difficulty is big, wastes time and energy; And the amplification coaxiality error then can make driveline vibrations obviously increase.
The permanent magnet clutch that patent ZL 00811078.6 provides, can address the above problem, the master end of shaft coupling is the cage type conductor rotor of band conducting ring, slave end is for installing the p-m rotor of permanent magnet, there is not mechanical attachment between them, but rely on the magnetive attraction to come transmitting torque, realized " the soft connection " between motor and the load equipment.
But torque transmitted is less between the magnet rotor of this permanent magnet clutch and the conductor rotor; Produce eddy-current heating in the conductor rotor, make the energy partial loss, transmission efficiency reduces; The volume of corresponding this permanent magnet clutch is also just bigger, just is difficult in the place of some limited space use.
Summary of the invention
The purpose of this invention is to provide a kind of permanent magnet clutch efficiently, improve the ability of transmitting torque, its volume is littler when transmitting identical torque.
The invention provides a kind of permanent magnet clutch, comprising: coaxial output shaft and power shaft; Cage rotor is installed in input shaft end, and the steel rotating disk of two constant spacings is arranged on it, and each installs a permanent magnetic rotation disc; Another permanent magnetic rotation disc is positioned in the middle of above-mentioned two permanent magnetic rotation discs, and each air gap that equates of keeping parallelism all with wherein is installed on the output shaft; One group of permanent magnet of all annular installation on the above-mentioned permanent magnetic rotation disc, its pole orientation and turntable shaft line parallel, and adjacent permanent magnet is extremely opposite.
The present invention also provides a kind of permanent magnet clutch, be installed in the cage rotor on the input shaft extension, three initiatively permanent magnetic rotation discs are arranged on it, by spacer sleeve they are separated into two equidistant fixed intervals, hold a driven permanent magnetic rotation disc that is installed on the hollow shaft in each interval, before being installed on the use equipment, the air gap that is limited between each active permanent magnetic rotation disc and each the driven permanent magnetic rotation disc by the jackscrew that is screwed into from the cage rotor two ends is equal and uniform state.Described hollow shaft is installed on the output shaft extension by inner expension cap.
Above-mentioned active permanent magnetic rotation disc and driven permanent magnetic rotation disc have two permanent magnetism pulling force faying faces, can transmit bigger torque, and in other words, volume can be less when transmitting identical torque.
Description of drawings
Fig. 1 is the longitudinal sectional view of one embodiment of the invention.
Fig. 2 is an A portion enlarged drawing among Fig. 1, shows that bright is the installation situation of jackscrew end anti-wear gasket.
