Abstract
The utility model relates to a direct current mute energy-saving electric roller, which combines a roller body of the electric roller and outer rotors of permanent magnet direct current motors into a whole and combines a motor shaft and a support shaft of the electric roller into the whole. A plurality of the permanent magnet direct current motors can be connected on the motor shaft in series for forming the low-speed and large-torque electric roller. The electric roller uses a servo current controller to stabilize the voltage of the electric roller, and the current and a load are directly proportional; and compared with a traditional alternating current electric roller, the current during the low load is reduced, and an energy-saving effect is achieved. A gearless transmission structure is adopted, and no lubricating oil exists in the electric roller, so that the electric roller has low noise and no oil leakage.
Description
Technical field
The utility model relates to a kind of direct current mute energy-saving motorized pulleys that are used for dynamo-electric load transfer device.
Background technology
Motorized pulleys are the actuating devices that are used for belt conveyer, and particularly the restriction owing to the device space is particularly suitable for using motorized pulleys on the miniature belt type conveyer.But for a long time the diameter of small-sized electric cylinder limited power increase, make less than normal, the particularly bigger noise of torque limit the use under the high-end in modern times working environment of motorized pulleys.Cause the reason of above problem to have:
1, general motorized pulleys adopt alternating current dynamo acceleration and deceleration device to drive more.Because the belt conveyer running velocity is lower, and need big torque, it is little to make that the small-sized electric cylinder adopts the method for pot motor (1500r/min) acceleration and deceleration device to satisfy volume, the requirement that torque is big.
2, the interior type of drive of many employings between motor and retarder, promptly motor is an internal rotor, slows down through retarder and passes to barrel to power again.This type of drive makes motor volume be difficult to dwindle, and has occupied the space in the barrel, makes the power of small-sized electric cylinder be difficult to strengthen.
3, the volume of high speed ratio speed reducer own is bigger, need cooling, lubricated when motor, retarder operation, and lubricants capacity can not be too small, like this, makes the volume of small-sized electric cylinder be difficult to dwindle.
4, high-speed electric expreess locomotive and multipole retarder increase the operation noise of small-sized electric cylinder, are difficult to make the user to accept.
5, because the running of motorized pulleys motor internal, retarder need be cooled off and lubricate, need install lubricating oil additional in the barrel.Because the existence of lubricating oil, motorized pulleys need sealing.Sealing technology be not good at slightly or period of service longer, all can cause motorized pulleys leakage of oil, contaminated environment.
6, its load when operation of general belt conveyer is a real-time change, and it is less that the motorized pulleys that alternating current dynamo drives adapt to the ability of load variations, conserve energy.Full load alternating current dynamo electric current when unloaded changes can only reach 20%, therefore, considerable for the waste of the belt conveyer that often is in zero load or low load (screening machine that uses like the public arena etc.) energy.
Summary of the invention:
The purpose of the utility model is to overcome the existing shortcoming of small-sized electric cylinder, provides motorized pulleys-----direct current mute energy-saving motorized pulleys of a kind of novel low speed, high pulling torque, low noise.
Be characterized in:
1, changing alternating current dynamo is DC machine, and adopts servo current controller control motor, makes full use of the big advantage of DC machine detent torque, under the situation of cancellation retarder, satisfies the detent torque of motorized pulleys and the requirement of operation torque.
2, the said direct current mute energy-saving of the utility model motorized pulleys adopt the external rotor electric machine structure; Two combine into one for motor housing and barrel, and the gear transmission that disappeared makes the cylinder intracorporeal space be used for enlarging capacity motor fully; Under the condition of equivalent diameter and tube length, make expanded motor power become possibility.
3, the external rotor electric machine of the said direct current mute energy-saving of the utility model motorized pulleys employing is arranged to reach many to high magnetic flux (UH38) magnet steel composition permanent magnet machine rotor ring in specific Φ 114mm diameter; The dicyclo winding stator that cooperates 27 grooves; Process the magnetic force effect that is higher than general excitation-type motor several times, given full play to DC machine detent torque and the big characteristics of driving torque.
4, the external rotor electric machine of the said direct current mute energy-saving of the utility model motorized pulleys is employed in the mode expanded motor capacity of a plurality of motor stator winding of series connection on the same motor shaft, has overcome overlength multiple-grooved stator winding and has made problem of difficult.
5, since motor adopt DC multipole, organize series system more; When electric motor starting and running, have enough moments of torsion; And owing to adopt outer-rotor structure, make motorized pulleys cancel transmission gear, adopt the direct operation scheme of motor; Make motorized pulleys inside need not install lubricating oil additional, thoroughly eliminated motorized pulleys leakage of oil hidden danger.
6, owing to adopt the many motor series connection of direct current single shaft high pulling torque external rotor electric machine; Motorized pulleys are started under lower-speed state and operation all the time; Owing to there is not gear drive, eliminate the operation noise of gear mechanism in addition, made cylinder operation noise be lower than 40dB (A).
7, the said direct current mute energy-saving of the utility model motorized pulleys use constant speed servo current controller, and sustaining voltage is constant when making the motorized pulleys operation, and moment of torsion is directly proportional with electric current, and promptly electric current is very little when belt conveyer zero load or low load.The operation test shows compares conserve energy significantly with the AC electrical cylinder.
