Abstract
The utility model relates to a kind of leaf spring, be structure as a whole, arcuation is become to bending two ends by center, comprise center rectangle section and be positioned at two end segments at two ends of center rectangle section, changeover portion is equipped with between center rectangle section and two end segments, the width of changeover portion narrows gradually to the direction away from described center rectangle section, the width of end segments also narrows gradually to the direction away from described center rectangle section, one end narrower with changeover portion, the wider one end of end segments is connected, and the center of center rectangle section has through hole.The motor of the utility model leaf spring and employing leaf spring, adopts leaf spring sheet to replace traditional wavy spring, achieves the object of damping noise reduction; Meanwhile, traditional corrugated sheet of comparing, leaf spring and the reduction gear area of contact below it less, surface friction drag is also little, naturally realizes reducing the better effects if of noise.
Description
Technical field
The utility model particularly relates to a kind of leaf spring and adopts the motor of leaf spring.
Background technique
Usual motor rotation vibration is large, noise is also large, if abatement vibration, reduce noise, be the problem of one of electromechanics trade comparatively headache, and conventional motors is all adopt wavy spring to reduce noise usually, although wavy spring can play the effect reducing noise, but the area of contact of wavy spring and the gear below it is comparatively large, and surface friction drag also increases thereupon.
Model utility content
The technical problems to be solved in the utility model is: in order to solve the above problems, and the utility model provides a kind of leaf spring and adopts the motor of leaf spring to solve the problems referred to above.
The utility model solves the technological scheme that its technical problem adopts: a kind of leaf spring, be structure as a whole, arcuation is become to bending two ends by center, comprise center rectangle section and be positioned at two end segments at two ends of center rectangle section, changeover portion is equipped with between described center rectangle section and two end segments, the width of described changeover portion narrows gradually to the direction away from described center rectangle section, the width of described end segments also narrows gradually to the direction away from described center rectangle section, one end narrower with changeover portion, the wider one end of described end segments is connected, the center of described center rectangle section has through hole.
A kind of motor adopting above-mentioned leaf spring, comprise motor casing, the motor output shaft be encapsulated in motor casing, many group reduction gear and many reducing gear wheel shafts, often organizing reduction gear is enclosed within corresponding reducing gear wheel shaft, between described reduction gear and motor casing, leaf spring is set, the through hole of described leaf spring mates with reducing gear wheel shaft, described leaf spring is enclosed within reducing gear wheel shaft by through hole, and motor casing inwall is withstood to motor casing inwall direction projection in the two ends of described leaf spring.
Described leaf spring is arranged on the reducing gear wheel shaft with motor output shaft transmission or is arranged on often to be organized on reducing gear wheel shaft.At the reducing gear wheel shaft upper mounting plate formula spring with motor output shaft transmission, damping noise reduction effect is the most obvious, simultaneously in order to cost-saving and artificial, adopts in this way; If but want to strengthen effect further, also can install leaf spring additional on every root reducing gear wheel shaft.
The beneficial effects of the utility model are, the motor of the utility model leaf spring and employing leaf spring, adopt leaf spring sheet to replace traditional wavy spring, achieve the object of damping noise reduction; Meanwhile, traditional corrugated sheet of comparing, leaf spring and the reduction gear area of contact below it less, surface friction drag is also little, naturally realizes reducing the better effects if of noise.

In figure 1, center rectangle section, 2, end segments, 3, changeover portion, 4, through hole, 5, motor output shaft, 6, reduction gear, 7, reducing gear wheel shaft, 8, leaf spring.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, the utility model leaf spring, be structure as a whole, arcuation is become to bending two ends by center, comprise center rectangle section 1 and be positioned at two end segments 2 at two ends of center rectangle section 1, changeover portion 3 is equipped with between center rectangle section 1 and two end segments 2, the width of changeover portion 3 narrows gradually to the direction away from described center rectangle section 1, the width of end segments 2 also narrows gradually to the direction away from described center rectangle section 1, one end narrower with changeover portion 3, the wider one end of end segments 2 is connected, and the center of center rectangle section 1 has through hole 4.
As shown in Figure 2, a kind of motor adopting above-mentioned leaf spring, comprise motor casing, the motor output shaft 5 be encapsulated in motor casing, many group reduction gear 6 and many reducing gear wheel shafts 7, often organizing reduction gear 6 is enclosed within corresponding reducing gear wheel shaft 7, leaf spring 8 is set between reduction gear 6 and motor casing, the through hole 4 of leaf spring 8 mates with reducing gear wheel shaft 7, leaf spring 8 is enclosed within reducing gear wheel shaft 7 by through hole 4, and the two ends of leaf spring 8 are protruded to motor casing inwall direction and withstood motor casing inwall.
Embodiment 1: leaf spring 8 is arranged on on the reducing gear wheel shaft 7 of motor output shaft 5 transmission.
Embodiment 2: leaf spring 8 is arranged on often to be organized on reducing gear wheel shaft 7.
Embodiment 1 and embodiment 2 respectively have quality, mode in embodiment 1, cost of material and cost of labor all reduce, and at the reducing gear wheel shaft 7 upper mounting plate formula spring 8 with motor output shaft 5 transmission, and other reducing gear wheel shaft 7 effect of comparing is the most obvious, mode in embodiment 2, shock-absorbing noise-reducing effect is also fine, but every root reducing gear wheel shaft 7 is all installed, and the effect embodiment 1 that compares is better, but friction area adds, simultaneously cost increase.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
