Abstract
The invention relates to a low-noise rotating shaft used for a low-noise motor. The rotating shaft is provided with a shaft, a rotor and two bearings, wherein the rotor is provided with a shaft hole; the shaft is pressed in the shaft hole of the rotor after the shaft is provided with a vibration reduction ring at a matching part of the shaft and the rotor shaft hole; both sides of a fixing piece are respectively provided with an anti-skid sleeve; and the two bearings are respectively pressed outside each anti-skid sleeve. The vibration reduction ring is added between the rotor and the shaft, thereby effectively stopping the rotor from transmitting vibration to the shaft so as to reduce noise generated by vibration when the motor is operated, and meet the requirement on noise of floor air conditioners of high-grade places such as villas, clubs, and the like.
Description
Technical field
The present invention relates to a kind of low-noise rotating shaft that is used for the low noise motor.
Background technology
At air conditioner industry, in order to reduce the noise that the motor electromagnetic vibration is produced, mainly be stator to be installed body carry out the rubber damping design, rotor is not had any Vibration Absorption Designing.And in fact, because air-gap field not only has first-harmonic, and also have a series of high order harmonic components to exist, these magnetic field interactions will produce periodic active force, first-harmonic and high order harmonic component electromagnetic force all can cause vibration and noise, motor is in operation process, and the alternating electromagnetic force that acts in the motor gas-gap can make motor stator, rotor produce vibration and noise.
The low noise motor is used for villa, the contour shunting yard of club the floor air-conditioning, requirement to noise is very strict, and the noise level of the A weighted sound power level that conventional room air conditioner fan motor general technical specifications regulation motor records when no-load running in the industry is no more than 40dB (A), and in high-grade club, motor to the floor air-conditioning requires higher, the noise level of the A weighted sound power level that the requirement motor records when no-load running is no more than 23.5dB (A), the minimum 26dB of accomplishing of noise level (A) of the A weighted sound power level that the existing motor of making records when no-load running, can not satisfy above-mentioned requirements, so, must design a kind of low-noise rotating shaft, be used for the low noise motor, to adapt to of the requirement of floor air-conditioning to low noise.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of low-noise rotating shaft is provided, be used for the low noise motor, the noise level of the A weighted sound power level that motor records when no-load running is no more than 23.5dB (A), satisfies the requirement to noise of villa, contour shunting yard institute of club floor air-conditioning.
The technical solution adopted for the present invention to solve the technical problems is: a kind of low-noise rotating shaft, be used for the low noise motor, have axle, be enclosed within rotor and two bearings on the axle, described axle is fitted in the axis hole of rotor after damping ring is loaded onto in the cooperation place of itself and rotor shaft hatch.
Further, described damping ring outer ring is surrounded by stator, and stator is fitted in the axis hole of rotor in the lump with the axle that damping ring is housed.Stator can improve the assembly technology of damping ring and rotor, and rotor is cooperated with the damping ring rigidity.
Further, described stator both sides respectively are equipped with an anti-sliding sleeve, and described two bearings are fitted in the outside of each anti-sliding sleeve respectively.Rotor separated with axle after anti-sliding sleeve can effectively prevent the stator slippage.
Further, described stator is each self-dispersed three stator, is distributed in the damping ring outer ring.
Further, described rotor is a cast-aluminum rotor.
The invention has the beneficial effects as follows: sound betides the vibration of object, vibration just can sound, the noise of motor is because the vibration of motor produces, damping ring, stator, anti-sliding sleeve forms the damping means between rotor and the axle, effectively cut off rotor with its transfer of vibration to the axle, thereby the noise that has produced because of vibration when having reduced motor rotation, low-noise rotating shaft of the present invention is installed on the motor, the noise level of the A weighted sound power level that this motor records when no-load running is 22.0dB (A), has satisfied villa, contour shunting yard institute of club floor air-conditioning is to the requirement of noise.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the scheme of installation of each parts among the present invention;
Wherein: 1. spool, 2. rotor, 3. bearing, 4. damping ring, 5. stator, 6. anti-sliding sleeve
Embodiment
The low-noise rotating shaft shown in Figure 2 as Fig. 1 has axle 1, is enclosed within axle cast-aluminum rotor 2 and two bearings 3 on 1, and rotor 2 has axis hole, and axle 1 is equipped with damping ring 4 in the cooperation place of itself and rotor 2 axis holes.
Damping ring 4 outer rings are surrounded by stator 5, and stator 5 is each self-dispersed three stator, is evenly distributed on damping ring 4 outer rings.Damping ring 4 is the rubber damping circle, and stator 5 is the metal stator.Stator 5 is fitted in the axis hole of rotor 2 in the lump with the axle 1 that damping ring 4 is housed.
Stator 5 both sides respectively are equipped with the outside that 6, two bearings 3 of an anti-sliding sleeve are fitted in each anti-sliding sleeve 6 respectively.
Damping ring 4, stator 5, anti-sliding sleeve 6 form the damping means between rotor 2 and the axle 1, effectively cut off rotor 2 with its transfer of vibration to the axle 1, thereby the noise that has produced because of vibration when having reduced motor rotation, this low-noise rotating shaft is installed on the motor, the noise level of the A weighted sound power level that this motor records when no-load running is 22.0dB (A), has satisfied the requirement to noise of villa, contour shunting yard institute of club floor air-conditioning.
