Description
Technical field
The utility model relates to a kind of drive system, is specifically related to a kind of drive system with permanent magnetic speed-adjusting clutch.
Background technology
In the drive system of being formed by load equipment and motor, between load equipment and the motor to connect modal be to adopt the hard mode that connects, the power shaft that is exactly motor shaft by shaft coupling and load equipment links.It has following characteristics: 1) high rigidity, high torque (HT), low inertia; 2) high pulling torque carrying, high moment of torsion rigidity and remarkable sensitivity; 3) zero revolution gap, identical with the turning anticlockwise characteristic clockwise; 4) non-maintaining, superpower anti-oil and corrosion resistance.
But this drive system also exists more technical problem.
One, conventional motors adopts the hard reboot mode, and the big electric current during startup impacts bigger to electrical network, influence grid supply quality; The injury electrical machine insulation reduces electrical machinery life; Produce very big impulsive force at coil of stator of motor and rotor squirrel-cage bar, can cause motor tightly dead, winding deformation, faults such as squirrel-cage bar fracture.
Two, can't realize overload protection, when the bearing power of motor had surpassed its rated power, motor probably burnt out because its internal current is excessive.
Three, motor is when hard reboot, load equipment impacted bigger, influences useful life.
Four, owing to be hard the connection between motor and the load, so the vibration of load can be passed on the motor, influence motor useful life.
From the above, motor transmission system of the prior art because there are problems such as hard reboot, no overload protection and life-span weak point in it, has limited it in the application of occasion of having relatively high expectations.
Clutch also is common in the drive system, clutch can be divided into electromagnetic clutch, magnetic powder cluth, slip clutch and fluid clutch etc., mainly refer under the situation of active part running, make secondary part be combined with active part or separate, but the product that in the prior art clutch is combined with speed governing is but very few.
The utility model content
The technical problems to be solved in the utility model provides a kind of drive system with permanent magnetic speed-adjusting clutch, and the adjusting that can provide soft-start feature also can realize load speed is to overcome the above-mentioned deficiency of prior art.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of drive system with permanent magnetic speed-adjusting clutch, comprise motor, clutch and load equipment, the driving disc spacing pressing of described clutch is connected with motor output shaft, the clutch plate of clutch is connected with the power shaft of load equipment, the front of described driving disc spacing pressing is installed with conductor disc, be installed with permanent magnet on the described clutch plate, the magnetic pole of permanent magnet is positioned at the front of clutch plate, the front of described driving disc spacing pressing is with the positive coaxial relative of clutch plate but do not contact, be provided with air gap between the magnetic pole of described conductor disc and permanent magnet, described motor or load equipment are installed in and can regulate on the sliding bottom.
Preferably, fixedly there is fin at the back side of described driving disc spacing pressing.
Preferably, fixedly there is pressing plate at the back side of described clutch plate, and described pressing plate is pressed on permanent magnet on the clutch plate.
Preferably, described conductor disc is copper dish or aluminium dish.
Preferably, input flange is arranged fixedly on the described driving disc spacing pressing, input flange connects with motor output shaft by expansion set.
Preferably, output flange is arranged fixedly on the described clutch plate, output flange connects with the power shaft of load equipment by expansion set.
Compared with prior art, the utlity model has following advantage:
(1) have soft start function: during electric motor starting, driving disc spacing pressing and the distance between the clutch plate of clutch are bigger, and slippage is 100%, and empty load of motor is started.After electric motor starting was finished, recycling can be regulated sliding bottom and be regulated air gap between driving disc spacing pressing and the clutch plate, and load speed is adjusted to the rotating speed that needs, can effectively reduce power drive system impact, ancillary equipment is played a protective role.
(2) can drive higher startup inertia or moment of torsion: during traditional drive system starter motor, it starts inertia must over proof tens times, adopt the utility model scheme can reduce the motor moment of inertia effectively when selecting motor.
(3) vibration damping: the transmission of the driving disc spacing pressing of clutch and the rotating speed between clutch plate connects by magnetic field in the utility model, is a kind of soft connecting mode, and the vibration of load end is effectively isolated, and prolongs electrical machinery life.
(4) can bear periodic load stall (slippage): when load equipment during stuck or stall, the load end rotating speed that do not change or slow down, and motor can continue rotation by original rotating speed, thus can avoid motor to burn out because internal current is excessive effectively.
(5) adjustable speed control load moment of torsion: by regulating sliding bottom mobile motor or load equipment, with the size of gaps between control conductor disc and the magnetic pole, the size of control load driving torque reaches energy-saving effect.
(6) can realize the disengaging of motor and load equipment: when the air gap between driving disc spacing pressing and the clutch plate is enough big, load is broken away from fully, be applicable to that multimachine unites the application scenario of driving, motor frequent starting, or satisfy the operating mode of load frequent interruption work.
