Problems solved by technology

[0002] For the current electric motor, its power is output through a single shaft. When working, the load exerts a resistance opposite to the torque of the rotating shaft on the rotating shaft. The resistance acts on the motor in the form of fluctuations, causing the motor to generate an asymmetrical fluctuation external force. This external force causes the bolts of the motor to produce a directional warping force, which makes the fixing bolts of the motor very easy to loosen under the action of vibration, thus generating a lot of vibration noise and quickly forming a greater degree of vibration

Embodiment 1

[0013] exist figure 1 In the first embodiment shown, the low-vibration motor includes a motor housing 1, and the motor housing 1 includes two parallel inner cavities, and each of the inner cavities is provided with a stator 11 and a rotor 12 respectively; The rotating shafts of the rotors 12 in the two inner cavities are independent of each other and have the same axis, and each rotating shaft protrudes from one end of the motor housing 1 to form the drive shafts 121 and 121 ′ respectively.

[0014] When the motor is running, the two rotors 12 rotate in opposite directions; specifically, the rotors 12 can adopt a tumbler structure, the stator 11 is a coil stator, and the stators 11 in the two inner cavities are energized. When the magnetic field rotates in opposite directions, the two cages rotate in opposite directions.

[0015] The drive shafts 121 and 121' are provided with drive gears 1211 and 1211'. The drive gears on the two drive shafts mesh together with a ring gear 2...

Embodiment 2

[0019] for figure 2 The second embodiment shown is different from the first embodiment in that: the turntable 2 is provided with two annular racks 21 and 22 from the outside to the inside, and the number of teeth of each annular rack is proportional to the diameter of the rack; And each of the drive shafts 121, 121' has two drive gears 1211, 1212, 1211', 1212' respectively, and the number of teeth of the drive gears 1211, 1212, 1211', 1212' is equal; wherein the drive gears 1211, 1211' A ring gear 21 with a larger diameter is engaged; the driving gears 1212 and 1212' are engaged with a ring gear 22 with a smaller diameter; the circumferential controllable cooperation between the driving gear and the driving shaft, that is, there is a space between the driving shaft and the driving gear. The circumferential locking mechanism realizes the circumferential fixing or loosening between the drive gear and the drive shaft; specifically, the locking mechanism may be a drum brake mecha...

Abstract

The invention provides a low-vibration motor. The low-vibration motor comprises a motor shell, the inner side of the motor shell comprises two inner cavities arranged in parallel, a stator and a rotor are arranged in each inner cavity, rotating shafts of rotors in the two inner cavities are independent from each other and have the same axis, each rotating shaft extends out of one end of the motor shell to form a driving shaft, the two rotors rotate in a reverse direction during the operation of the motor, the driving shaft is provided with a driving gear, the driving gears of the two driving shafts are engaged with an annular rack parallel to the driving shafts, the annular rack is fabricated on a rotating disc parallel to the driving shafts, and an output shaft vertical to the rotating disc is fixed at the center of the rotating disc. When the motor outputs power, the stress of fixing bolts is uniform, the axial pulling force is avoided, fixing facilities do not easily get loose, and low vibration noise is maintained.

Description

technical field [0001] The present invention relates to the field of electromechanical equipment, in particular, to an electric motor. Background technique [0002] For the current motor, its power is output through a single shaft. During operation, the load exerts a resistance opposite to the torque of the rotating shaft to the rotating shaft. The resistance acts on the motor in the form of waves, causing the motor to generate an asymmetrical wave. The external force causes the bolts of the motor to generate a directional warping force, so that the fixing bolts of the motor are easily loosened under the action of vibration, thereby generating a large amount of vibration noise and rapidly forming a greater degree of vibration. SUMMARY OF THE INVENTION [0003] In view of the above problems, the purpose of the present invention is to provide a low-vibration motor. When the motor outputs power, the fixing bolts of the motor are uniformly stressed and have no axial tension, s...
