Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, by the following examples, and by reference to the accompanying drawings, vibration-reduction gear of the present utility model and motor and electrical equipment are further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, a vibration-reduction gear, comprises gear body 100, shock absorbing sleeve 200 and coordinates axle sleeve 300, and gear body 100, shock absorbing sleeve 200 and cooperation axle sleeve 300 are all loop configuration, coordinate axle sleeve 300 to be socketed in shock absorbing sleeve 200, shock absorbing sleeve 200 is socketed in gear body 100.Wherein, shock absorbing sleeve 200 is made and is had good effectiveness in vibration suppression by damping material, while there is vibration in gear body 100 or cooperation axle sleeve 300, vibration is delivered to shock absorbing sleeve 200, shock absorbing sleeve 200 has reduced the amplitude of vibration, amplitude has reduced, thus by the noise of generation of vibration, also just reduced, thus reach the effect that reduces noise.
As a kind of embodiment wherein, gear body 100 and/or cooperation axle sleeve 300 are made by engineering plastics, such as: effectiveness in vibration suppression such as PA66, PA6, POM better and there is the material of higher-strength, the gear body that adopts engineering plastics to make, for metal gear, in engagement process, can not produce metal Strike note, effectively reduce noise.Coordinate axle sleeve 300 to be made by the good engineering plastics of effect of vibration and noise reduction, also can aluminium etc. light-weight metal.
As a kind of embodiment wherein, the making material of shock-reducing sleeve 200 adopts good damping result and has the rubber material of wear-resisting property, such as ethylene propylene diene rubber, fluorine rubber etc.
As in Figure 3-5, as a kind of embodiment wherein, shock absorbing sleeve 200 outer is equipped with a plurality of the first raised lines 210, is equipped with a plurality of the second grooves 220 in shock absorbing sleeve 200; What coordinate axle sleeve 300 is equipped with a plurality of the second raised lines 310 that match with the second groove outward, is equipped with a plurality of the first grooves 120 that match with the first raised line 210 in gear body 100; When shock absorbing sleeve 200 is socketed in gear body 100, the first raised line 210 is close to the first groove 120; When coordinating axle sleeve 300 to be socketed in shock-reducing sleeve 200, the second raised line 310 is close to the second groove 220.Shock-reducing sleeve 200 matches by the first groove 120 of a plurality of the first raised lines 210 and gear body 100, when guaranteeing reliable transmission, reduces the circumferential rigidity of shock-reducing sleeve 200, thereby promotes the deformation raising vibration attenuation of shock-reducing sleeve 200.
Wherein, the first raised line 210 equates with the quantity of the first groove 120, and preferably, the quantity of the first raised line 210 and the first groove 120 is all greater than or equal to 6; The second raised line 310 equates with the quantity of the second groove 220, preferably, the quantity of the second raised line 310 and the second groove 220 is all greater than or equal to 6, and in the present embodiment, the quantity of the first raised line 210, the first groove 120, the second raised line 310 and the second groove 220 is all 6.
Based on same object, the invention also discloses a kind of motor, vibration-reduction gear in above-described embodiment is installed on the output shaft of motor, and the interior ring of the cooperation axle sleeve 300 of vibration-reduction gear is provided with flat position 320, matches with the output shaft of motor and prevent idle running in flat position 320.
The utility model also provides a kind of electrical equipment, comprises vibration-reduction gear described in above embodiment or the motor described in above embodiment, and this electrical equipment reduces noise by above-mentioned vibration-reduction gear or motor.
Vibration-reduction gear of the present utility model comprises gear body 100, shock absorbing sleeve 200 and coordinates axle sleeve 300 3 parts, shock absorbing sleeve 200 is socketed in gear body 100 and coordinates between axle sleeve 300, shock absorbing sleeve 200 adopts rubber material to make, have good effectiveness in vibration suppression, gear body 100 and/or cooperation axle sleeve 300 adopt the good engineering plastics of effect of vibration and noise reduction to make.When vibration occurs in outside, vibration is delivered to shock absorbing sleeve 200, and shock absorbing sleeve 200 reduces amplitude, and the noise that amplitude sends due to vibration after reducing also decreases, thereby reaches the effect that reduces noise.
