Description

The synchronous motorized pulleys of low speed high torque gearless permanent-magnet
Technical field
The utility model relates to a kind of motorized pulleys that are used for the transmission equipment actuating device, particularly a kind of motor and cylindrical shell close-the synchronous motorized pulleys of low speed high torque gearless permanent-magnet of high driving efficiency, what it can be widely used in system such as metallurgy, machinery, chemical industry, coal, mine, building materials, electric power, light industry, grain, warehouse, harbour, supermarket or department has the various conveyers that motorized pulleys that low speed and super large torque characteristics require drive and various transmission equipments of industrialization automatic streamline operation.
Background technology
At present, the actuating device of the various transmission equipments of various conveyers and the operation of industrialization automatic streamline, the general motorized pulleys that adopt are conveyings that the cylindrical shell that utilizes the Asynchronous Motor Driving gear reduction unit to drive cylinder is realized material.The torque that requires when transmission equipment normally moves is very big, and the running velocity requirement is very low.When transmission equipment required torque of when starting generally is specified operation about 2 times, if asynchronous dynamo direct drive reductor drives the cylinder operation, 4-8 when the electric current that then starts the moment motor is specified operation doubly, this will cause very big impact to whole electrical network, mechanics to whole transmission equipment also can cause certain damage simultaneously, will shorten its service life.In addition, the rated speed of rotation of used asynchronous motor is higher, and torque is less, and its air-gap field is provided by stator current.The power factor of asynchronous motor is lower, and for improving the power supply voltage quality, increase equipment is exerted oneself, and need add reactive power compensator, and this has just increased the complexity of total system, has wasted material, has caused bigger waste of energy.The motorized pulleys type of drive of existing transmission equipment actuating device mainly contains two kinds: driving type in the first, be assembled in the inner barrel of cylinder after being about to asynchronous dynamo and gear reduction unit connecting by coupler, utilize the attaching parts drive of the mouth of gear reduction unit to be assembled in cylindrical shell rotation on the bolster.It has compact conformation, the advantage that volume is little, but because the space of inner barrel is less, assembling its interior asynchronous motor and the volume of gear reduction unit all can be restricted, so the torque of interior driving type motorized pulleys can not be accomplished very big, can't satisfy the requirement with slow speed of revolution and big torque characteristics driveability of various conveyers etc.It two is outer driving types, the input end that is about to the big parallel-axes gears reductor of reduction ratio and mouth are connected the rotating shaft of out of line high-power asynchronous motor and cylinder respectively by coupler, the cylindrical shell that utilizes rotating shaft to drive to be fixed in the rotating shaft rotates.This exterior drive configuration form of cylindrical shell that asynchronous motor and gear reduction unit is assembled in cylinder, though can satisfy the requirement with slow speed of revolution and big torque characteristics driveability of various conveyers etc., yet it not only exists machine volume is increased, take up room more, driving efficiency reduces, vibration and noise are serious, fault rate is higher, adjust defectives such as difficult in maintenance, and the cylindrical shell of cylinder is fixed in the rotating shaft, only plays the carrying effect, though the inner space of cylindrical shell is bigger, but be not fully utilized, caused the very big waste of energy and the waste of space and resource.
Driving type in the actuating device that adopts for " the adjustable speed motor formula cylinder " of CN2150664Y as patent announcement number.Also have improved motorized pulleys on the basis of this structure, as patent announcement number is " variable-frequency stepless speed-regulating motorized pulleys " disclosed motorized pulleys of CN2225454Y, though it has realized stepless stepless speed control, but still adopted the type of drive of asynchronous motor driven gear reductor, therefore, all there is the above-mentioned shortcoming of conventional electric cylinder in they.
The utility model content
The purpose of this utility model provides a kind of low speed large torque moment permanent-magnet synchronization gear wheel free motorized pulleys that are used for the transmission equipment actuating device, it fundamentally solved the driving efficiency that existing motorized pulleys exist low, take up room more, waste problem such as electric energy, it removes the compact conformation with interior driving type motorized pulleys, volume is little, outside the advantage of material-saving, can also reach steady, the safe in operation of starting of permagnetic synchronous motor, obviously reduce the purpose of vibration and noise, and significantly energy-conservation and raising driving efficiency increases the service life.
The technical scheme that the utility model adopted is: the synchronous motorized pulleys of this low speed high torque gearless permanent-magnet comprise cylindrical shell that is assembled on the bolster and the permagnetic synchronous motor that is integrated with cylindrical shell, its technical essential is: a left side that is fixed on described cylindrical shell two ends, the right disc that supports is contained on the bolster by bearing set respectively, the stator core that has stator winding of described permagnetic synchronous motor is assembled in the cylindrical shell, and with the rotor of cylindrical shell as described permagnetic synchronous motor, along described as week in the cylindrical shell of rotor attaching magnet steel, the axial length of described magnet steel is equated with the axial length of the stator core of described permagnetic synchronous motor, described stator core utilizes axle sleeve and described bolster to be fixed together, the pig-tail wire of described stator winding is drawn the connection external power supply by the through hole on the described bolster, and coder is installed in the right side of described cylindrical shell and supports on the disc.
Advantage and the good effect that the utlity model has are: because the employing of this device is with the cylindrical shell of the built-in magnet steel rotor as motor, the version that is combined into one dexterously with permagnetic synchronous motor, be assembled into the low speed large torque moment permanent-magnet synchronization gear wheel free motorized pulleys that are used for transmission equipment, so its reasonable in design, compact, simplified effectively, take up room except that having dwindling of interior driving type motorized pulleys, volume is little, outside the characteristics of material-saving, the driving efficiency that it has also fundamentally solved existing motorized pulleys existence is low, take up room more, problems such as waste electric energy.The air-gap field of these motorized pulleys mainly is to be provided by epitrochanterian magnet steel, and unlike asynchronous motor, air-gap field is provided by stator current.The synchronous motorized pulleys of low speed high torque gearless permanent-magnet of this new structure compare with existing like product that not only cost is low, remarkable energy-conservation and raising driving efficiency, increase the service life, and have steady, the safe in operation of starting of permagnetic synchronous motor, obviously reduce vibration and noise, but infinite speed variation, low and the big advantage of output torque of rotating speed, especially under the operating condition of low speed and underloading, its power savings advantages is more obvious, therefore, apply easily.
