Motorized pulleys are the driving portions of ribbon conveyer and traction-type lifting equipment used in the industries such as coal mine, building, chemical industry
Part.
Traditional built-in electric roller is rotated by multiple stage gear reduction device driving drum by motor, this built-in
The shortcomings that formula motorized pulleys, is, because the presence of gear reduction unit causes roller machine volume and occupied space bigger than normal；Because gear subtracts
Fast device high speed rotation keeps machine noise big, and temperature is high；Gear reduction unit is easy to wear, needs frequent lubricating maintenance；Motor passes through multistage
Driving causes roller high energy consumption, efficiency low to gear reduction unit indirectly.
To overcome the disadvantages mentioned above of the built-in electric roller driven by gear reduction unit, ZL201320170980.0's
Patent document discloses a kind of built-in electric roller directly driven to roller with magneto.The built-in electric rolls
The motor of cylinder takes outer rotor form, one is made in the inner wall of the periphery wall of rotor and barrel, by the direct band of rotor
Dynamic barrel rotation.Although the motorized pulleys eliminate gear reduction unit, improve mechanical efficiency, but because of motor and roller system
Integrally, a kind of roller can only be applicable in a kind of operating mode, cannot change with operating mode and replace motor, roller use scope is limited；In addition,
External rotor electric machine is used in greatly at present on generator or some small-sized electric appliances, the large size that mine is used with metallurgical large scale equipment
If roller is directly driven using external rotor electric machine, limited by current motor manufacturing technology, manufactured roller is difficult to ensure it
Operation stability, roller can cause heavy economic losses once breaking down.
Utility model content
To overcome the defect and deficiency of the above-mentioned built-in electric roller for taking external rotor electric machine, the utility model to provide one
The kind built-in electric rollers directly driven with permanent magnet synchronous motor different from its structure.
The motorized pulleys provided by the utility model directly driven with permanent magnet synchronous motor, including rotatingcylindrical drum body and it is placed in rolling
The permanent magnet synchronous motor of inner barrel；

It will not overheat when to make motor work, being fixedly mounted close to the filter screen in the front end of motor output shaft
Radiator fan.
The operation principle of the utility model motorized pulleys：
The stator of permanent magnet synchronous motor keeps motor relatively large by the motor fixed rack integral with rear fixed support shaft
Ground is stationary.Electric signal enters the excitation of permanent-magnetic synchronous motor stator by fixing the conducting wire of cable hole in support shaft after passing through
After winding coil, rotating excitation field is generated, makes rotor that output shaft rotation, output shaft be driven to drive the drum driven for being secured to connection
Wheel and radiator fan rotation.Wherein cylinder drive gear with the gear teeth meshing on barrel inner wall by driving barrel rotation；It dissipates
Hot-air fan rotation makes air be sucked from the air admission hole of drive end bearing bracket, by filter screen filtration, is then discharged from the gas vent of rear end cap,
Heat is taken away.
The utility model has the advantages that：
1, the motor of the utility model motorized pulleys and its fixing bracket and barrel are not directly connected, and can dismantle, from
And making roller that can replace motor with the variation of applying working condition, the scope of application of roller expands.
2, the driving motor of the utility model motorized pulleys is inner rotor motor, is not limited by existing motor manufacturing technology,
It can be made into the large-scale built-in electric roller for operating steadily, being used suitable for mine and metallurgical equipment.
3, the utility model motorized pulleys are due to eliminating speed reducer drive mechanism, make motorized pulleys have it is simple in structure,
Volume and occupy little space, simple and convenient operation and maintenance, good airproof performance, mechanical efficiency are high and advantage with long service life.
4, the heat generated when the utility model motorized pulleys are worked motor by the radiator fan being placed in barrel
It takes away, motor can be protected, will not be damaged because of overheat.
