Abstract
The utility model discloses a high speed motor with low noise, which comprises a casing (6), a rotor group (5) arranged inside the casing, a spindle (4) used for supporting the rotor group and a pair of bearings (2) which is used for supporting two ends of the spindle (4) respectively and arranged on the casing (6). One end of the spindle (4) extends out the casing, and a pendulum bob is arranged on the extended section of the spindle. A buffering gasket (3) is arranged between shoulders of the spindle (4) and a bearing base of the casing (6) corresponding to the shoulders of the spindle. The high speed motor with the low noise adopts the existing technology equipment so as to maintain the existing producing cost and can greatly reduce mechanical noise and dynamic noise of products (especially micro-motors with vibrating pendulum bobs) by adding abrasion resistant and heat resisting soft gaskets at the positions where the spindle of the motor collides with the casing.
Description
Technical field
The utility model relates to motor, relates in particular to a kind of micromachine that is used for, the high-speed electric expreess locomotive of the low noise in the products such as massager, Mature Audiences and care appliance.
Background technology
Current, because cost and manufacturing equipment precision, the rotating shaft of motor and the matched in clearance of housing are good inadequately, rotating shaft and the housing friction that can bump when causing motor to run up, therefore the noise of most of motor is all bigger on the market, and does not reach the low requirement of the noise that runs up.Accuracy of manufacture high energy reduces the noise of motor, but the cost height, and rate of finished products is low, is contrary to the principle in market.Can't produce low cost according to current technology, high efficiency, the product that noise is low can't satisfy enterprise and user's requirement.
Summary of the invention
The utility model proposes a kind of high-speed electric expreess locomotive of the low noise that adopts current production technology and produce in order to solve the existing high technical problem of motor noise that runs up.
For solving described technical problem, the high-speed electric expreess locomotive of the low noise that the utility model proposes, it comprises housing, is located at the rotating shaft of the interior rotor set of housing, support rotor group, is located at the pair of bearings that supports described rotating shaft two ends respectively on the described housing, one end of described rotating shaft stretches out housing, in this section rotating shaft pendulum is housed. be provided with buffering spacer between the shaft shoulder of the described rotating shaft housing shaft bearing relative with it.
Preferably, the end face of the relative shell inner surface of described rotating shaft is provided with described buffering spacer.
Described buffering spacer can adopt the soft pad of Wear-resistant, high-temperature resistant.
The utility model is in order to keep original production cost, so still adopt existing technical equipment, as long as the rotating shaft at motor has the place of collision to increase wear-resisting, resistant to elevated temperatures soft pad with housing, just can reduce the moving noise of mechanicalness noise, string of product (the especially electrical micro-machine that shakes with pendulum) greatly.Adopt the utility model not need existing equipment is upgraded, transformed, operate also extremely easyly, the noise of the motor of producing will be reduced greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further, wherein:
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1, the high-speed electric expreess locomotive of the low noise that the utility model proposes comprises housing 6, is located at rotor set 5 in the housing, the rotating shaft 4 of support rotor group, is located at the pair of bearings 2 that supports two ends, described rotating shaft 4 left and right sides respectively on the housing 6.The left end of rotating shaft stretches out housing, and a pendulum 1 is housed in this section rotating shaft.Be provided with buffering spacer 3 between the shaft shoulder of rotating shaft 4 housing 6 bearing pedestals relative with it.The right side of rotating shaft 4 relative housing 6 inner surfaces also can be provided with buffering spacer 3.The utility model buffering spacer 3 can adopt the soft pad of Wear-resistant, high-temperature resistant.
The utility model is in order to keep original production cost, so still adopt existing technical equipment, as long as the rotating shaft at motor has the place of collision to increase wear-resisting, resistant to elevated temperatures soft pad with housing, just can reduce the moving noise of mechanicalness noise, string of product (the especially electrical micro-machine that shakes with pendulum) greatly.
The above embodiment mainly is for creating conception of the present utility model is described; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
Claims (3)
1. the high-speed electric expreess locomotive of a low noise, comprise housing (6), be located at rotor set (5) in the housing, the rotating shaft (4) of support rotor group, be located at the pair of bearings (2) at the described rotating shaft of support respectively (4) two ends on the described housing (6), one end of described rotating shaft stretches out housing, pendulum (1) is housed in this section rotating shaft, it is characterized in that, be provided with buffering spacer (3) between the shaft shoulder of described rotating shaft (4) housing (6) bearing pedestal relative with it.
