Description
Technical field
The utility model relates to the drive technology field in the mechanical engineering, refers in particular to a kind of noncontact axial magnetized and encircles magnetic coupling more, and it can be applicable to big vibration, the big slow-revving non-contact mechanical drive system of torque.
Background technology
At mechanical engineering field, shaft coupling is widely used in machine driving and connects.Shaft coupling mainly is divided into rigidity and elasticity two big classes, and these two kinds of shaft couplings all can reach the effect of transferring power.But it is in the mechanism driving of some high rotating speeds, big vibration, has that transmission efficiency is low, energy loss greatly, easily produces rigid impact, part short shortcoming in useful life, and will consume a large amount of lubricating oil.At the above-mentioned shortcoming of shaft coupling, forefathers have proposed magnetic coupling, and it is different from other any shaft coupling; just being does not have Mechanical Contact between two half-couplinves; realize the noncontact transmission by magnetic force, dynamic seal (packing) can be converted into static sealing, and have advantages such as vibration isolation and overload protection.
Magnetic coupling can be divided into cartridge type magnetic coupling and disc magnetic coupling again, disc magnetic coupling with cartridge type magnetic coupling ratio have simple in structure, compact, axial dimension is lacked, save material, magnet ring manufacturing, easy for installation, and can regulate advantages such as torque transmitted by the change size of gaps.But because the magnetic pole on its two dish all is an axial magnetized, according to the magnetic pole same sex (there is a natural attraction between the sexes) principle of repelling each other, there is very big axial force in it on diaxon, for guaranteeing the stability of diaxon, must use the bearing of high rigidity or other bascule in two axial ends, therefore in power transmission process, spring bearing or bascule are bearing very big axial force, time one easily causes the spring bearing deterioration to strengthen for a long time, and shorten useful life, and bascule is damaged; And its transmitting torque is little, efficient is also low.This is the limitation that current traditional disc magnetic coupling exists.
Summary of the invention
The purpose of this utility model just provides that a kind of novel dish type magnetic coupling---the noncontact axial magnetized encircles magnetic coupling more.It had both kept the characteristics of traditional dish type magnetic coupling, had solved the defective that traditional dish type magnetic coupling axial force is big, transmitting torque is little again.Be specially adapted to big torque, slow-revving transmission.
A kind of noncontact axial magnetized encircles magnetic coupling more, comprises driving-disc assembly and clutch drived disk assy, and the driving-disc assembly is connected with driving shaft by flat key; Clutch drived disk assy is contained in driven shaft one end, it is characterized in that: the driving-disc assembly is made up of driving-disc matrix and driving-disc permanent magnet; The driving-disc permanent magnet glues by the N utmost point, the alternate tight arrangement of S utmost point even number and is contained on two end faces of driving-disc matrix; Driven rotating disk assembly is made up of the first clutch plate matrix, the second clutch plate matrix, clutch plate permanent magnet and sleeve; The clutch plate permanent magnet is contained on two inner faces of the first clutch plate matrix and the second clutch plate matrix by the N utmost point, the alternate tight arrangement of S utmost point even number are sticking respectively, and its magnetic is relative with the driving-disc permanent magnet on the driving-disc matrix end face.
In the above-mentioned shaft coupling, the N utmost point of driving-disc permanent magnet and clutch plate permanent magnet and the S utmost point can the monolithic magnet be a utmost point both, also can the polylith same polarity, unidimensional toroidal magnet is a utmost point.In the above-mentioned shaft coupling, the first clutch plate matrix is connected by screw with the second clutch plate matrix.
In this device, the extremely tight permanent magnet alternately of the N utmost point and S is housed on two end faces of driving rotating disk; Two matrix inner faces of clutch plate also are equipped with the N utmost point and the extremely tight permanent magnet alternately of S, and relative with the permanent magnet magnetic that drives rotating disk, form high-octane magnetic field.When inactive state, the permanent magnet N utmost point and the S utmost point of two dishes attract each other in line, and torque this moment is zero.When under driving the drive of rotating disk, rotating at motor, drive angle of the driven relatively rotating disk skew of rotating disk, because the existence of this angle, the N utmost point of permanent magnet (the S utmost point) has the effect of a pulling on the driving-disc to the S utmost point (the N utmost point) of permanent magnet on the clutch plate, the N utmost point (the S utmost point) on the driving-disc has an impetus to the previous N utmost point (the S utmost point) on the clutch plate simultaneously, its tangential force stack promptly drives clutch plate and does motion in the same way, thereby realizes the transmission of torque.
Advantage of the present utility model: between two relative permanent magnets, also have very big axial force though the noncontact axial magnetized encircles magnetic coupling more, but the driven relatively rotating disk base shaft of the permanent magnet of this shaft coupling is to symmetry, two groups of relative permanent magnets produce equal and opposite in direction, magnetic field force that direction is opposite, on axle, cancel out each other for a pair of equilibrant force, therefore reduce the stressed of diaxon, made transmission more steady; The transmission of magnetic coupling torque is to realize by magnetic field, air gap simultaneously, the utility model is compared traditional dish type magnetic coupling, many working gas gap magnetic fields, as under same main rotating speed, its torque transmitted is bigger than traditional dish type magnetic coupling torque transmitted, efficient is higher, has solved the little defective of traditional dish type magnetic coupling transmitting torque.
