Embodiment
Below, describe the example of the execution mode that the present invention is correlated with reference to the accompanying drawings in detail.
Fig. 1 is, used the structure chart of the gear motor GM101 that the door switch of the relevant motor of the embodiment of the invention uses, be that positive sectional view, (B) are side cross-sectional view (A).Fig. 2 is with the overall structure figure 300, that be used for switch door of said gear motor GM101 as the translator power transmission.
Gear motor GM101 is that output shaft 114 drive pulleys 302 of this gear motor GM101 thus, carry out the switch of automatically-controlled door 303 by door driving belt 301 with the motor of small-gear integral motor 102 and decelerator 130 bindings.Decelerator 130 is the one-level orthogonal types with hypoid pinion 112 and hypoid gear 116.
The motor shaft 104 of above-mentioned small-gear integral motor 102 is installed in the end cap 122a of motor case 122 by bearing 136, and is installed in by bearing 138 on the protecgulum 122c of motor case 122, is supported by 2 axles.Motor case 122 main body 122b central authorities roughly near the position of protecgulum 122c, be built-in with the armature coil (stator) 142 of no iron core, printed circuit board 140 adheres to this armature coil (stator) 142.
At this armature coil 142, rotor magnet (rotor) 144 is with mutually opposed from the form that the direction of principal axis of motor shaft 104 sandwiches this armature coil 142 across opposed clearance G 1.This rotor magnet (rotor) 144 is installed on the motor shaft 104 by rear magnetic yoke 146, is provided with magnetic inductor (hall integrated circuit, Hall unit) 148 near this rotor magnet (rotor) 144.
That is, this small-gear integral motor 102 is that the opposed clearance G 1 of rotor magnet (rotor) 144 and armature coil 142 is formed on no iron core brushless direct current (DC) motor of the axial axial-gap of motor shaft 104.
In addition, above-mentioned hypoid pinion 112 vertical cuts are formed on the front end of motor shaft 104.That is the power shaft of motor shaft 104 double as decelerators 130.Hypoid pinion 112 is in the face of the inside of reduction-gear housing 120, with hypoid gear 116 engagements in this reduction-gear housing 120.Hypoid gear 116 is installed on the output shaft 114.Output shaft 114 is installed on the box main body 120a of reduction-gear housing 120 by bearing 106, and is installed on the output shaft-cup 120b by bearing 108.By this structure, motor shaft 104 and output shaft 114 quadratures.
