Embodiment
Below, with reference to accompanying drawing, embodiments of the present invention are illustrated.
As shown in Figures 1 to 3, of the present invention with reductor motor by after possessing the motor body 2 of rotating shaft 21 and the rotation of rotating shaft 21 and slowing down from output shaft 17A(with reference to Fig. 3) output, it can be used as drive source use of Wiper system vehicle for, electric window device, skylight device etc.
The reductor 1 of fixing, be connected in motor body 2 is contained in gear box 11, and this gear box 11 is fixed on motor body 2.And gear box 11 consists of 2 parts such as above-below direction (gear box main body 11 ', lid 11 "), is fixed by fixing meanss such as screws 18,18,18.
More specifically, of the present invention with in the gear box 11 in reductor motor, have and can rotate freely the bearing 13 that supports the worm screw 12 that the rotating shaft 21 with motor body 2 is coaxially fixed wtih, also accommodate: worm gear 14, it is snapped at worm screw; Pinion 15, itself and worm gear 14 coaxially arrange, and together rotate freely with worm gear 14; Output gear 16, itself and pinion 15 interlocks.With this, formed reductor 1.
That is, structure with reductor motor of the present invention is: be situated between by the worm screw 12 of being fixed on rotating shaft 21, after being slowed down by the revolving force of the rotating shaft 21 of the worm gear 14 coaxially arranging and 15 pairs of motor bodies 2 of pinion, conducted to output gear 16, by efferent 17 outputs that are connected in output gear 16.
In band reductor motor of the present invention, the rotating shaft 21 of one end of worm screw 12 and motor body 2 is fixing, and the other end can be rotated freely and support by the bearing 13 in gear box 11.Thus, it forms the structure that is conducive to bear the radial load producing between worm screw 12 and worm gear 14.
In addition, the rotating shaft 21 of motor body 2 is to form with worm screw 12 splits, therefore can do smaller and more exquisitely, the volume of motor body 2 also can correspondingly dwindle, and can realize lightweight, cutting down cost.
And the number of teeth that conducts to the pinion 15 of output gear 16 after in band reductor motor of the present invention, coaxially arranging with worm gear 14, revolving force being slowed down is preferably 5～7, more preferably 5 or 6.
Like this, the number of teeth by pinion 15 is set to 5～7, can obtain larger modulus.That is, if the number of teeth of pinion 15 is set to 5～7, than the pinion that adopted so far, can obtain 2 times of above moduluses, and the gear teeth intensity of pinion 15, than the pinion that adopted so far, also reaches more than 2 times.And, with the profile of tooth of the worm gear 14 of the coaxial setting of pinion 15 in the present invention can be existing known standard type profile of tooth.
For this reason, needn't as prior art, a plurality of worm gears and pinion be set, by a worm gear 14 and pinion 15, can form of the present invention with the reductor 1 in reductor motor.
Therefore, the number of teeth by pinion 15 is set to 5～7, part that can be less and simple structure formation band reductor motor.
In addition, in band reductor motor of the present invention, with pinion 15 interlocks and be fixed on the output gear 16 of output shaft 17A, for having the gear of the tooth curve extending along crown direction or the tooth root direction of involute curve, from the viewpoint of output and noise angle, preferably pinion 15 is more than 1.0 with the interlock rate of described output gear, and sliding ratio is below 20.
Above embodiments of the present invention are illustrated, but the present invention is not limited to these execution modes.
For example, in execution mode, band reductor motor is illustrated, and the reductor itself of fixing, be connected in motor also belongs to category of the present invention.
Utilizability in industry
In band reductor motor of the present invention, the rotating shaft of one end of worm screw and motor body is fixed, and the other end can be rotated freely and support by the bearing in gear box.For this reason, its structure is conducive to bear the radial load producing between worm and worm wheel.
In addition, in band reductor motor of the present invention, the rotating shaft of motor body and worm screw split form, and that can do is smaller and more exquisite, and the volume of motor body 2 can dwindle correspondingly, can realize lightweight, cutting down cost.
In desirable execution mode of the present invention, the number of teeth of pinion is set to 5～7.For this reason, than the pinion that adopted so far, can obtain 2 times of above moduluses, and the gear teeth intensity of pinion, than the pinion that adopted so far, also can reach more than 2 times.Therefore, needn't as prior art, a plurality of worm gears and pinion be set, can consist of of the present inventionly with the reductor 1 in reductor motor a worm gear and pinion, part that can be less and simple structure, form band reductor motor.
