Definitions

• the present invention relates to a starting motor used, for example, as a starter of an automobile, and more particularly to a structure for removing foreign matter attached to the inside of the motor.
• a housing (1) is composed of a cylindrical yoke (), a front storage body ( 3 ) and a rear storage body ( 4 ) mounted on both ends of the yoke (2), respectively.
• a field core (5) and a field winding ( 6 ) are mounted inside the yoke (the front housing (3) and the rear housing ( 4 ) have bearings 3a) and ( 3 ), respectively.
• a rotating shaft ( 7 ) is rotatably mounted via (4a) The armature disposed on the rotating shaft (7) to face the field iron core ( 5 ) with a predetermined gap therebetween And a pinion ( 9 ) for transmitting a rotational force generated in the armature (8) to a starting gear ⁇ ⁇ which is coupled to a drive shaft (not shown) of the engine.
• the rotational force of the child (8) is mounted slidably in the O ⁇ "Barra Nni Nguku latch 3 ⁇ 4 axial direction to transmit only in one direction to the pinion (9) (this O-bar running The latch 3 ⁇ 4, the locking portion
• the starting switch is turned on, the electromagnetic switch ⁇ is operated, and the overrunning clutch 0 and the pinion ( 9 ) are moved rightward through the lever ⁇ . And the pinion ( 9 ) engages with the gear.
• the contacts in the electromagnetic switch are closed and power is supplied to the field winding ( 6 ) and the armature ( 8 ), and the armature ( 8 ) and the rotating shaft (7) are integrated.
• This rotational force is transmitted to the pinion ( 9 ) via the overrunning clutch 0 ⁇ , and further transmitted from the pinion ( 9 ) to the gear to start the engine.
• the pinion ( 9 ) cannot be engaged with a gear (in this case, it cannot move to the right in the figure. On the other hand, even in such a state, the contacts in the electromagnetic switch ⁇ are closed. As a result, the armature ( 8 ) starts to rotate, and the pinion ( 9 ) slips between its end face and ice and snow, causing the armature to only spin and transmit torque to the gear. becomes not possible.
• conventional starter motor to cormorants good this is the bearing portion of the front housing body (3) and (3a) and a pinion (9) Pinio down by snow and ice which is fixed between (9) and the gear Can no longer engage, resulting in poor starting of the engine There was a problem.
• the present invention has been made to solve the above problems, and has as its object to provide a starting motor capable of removing ice and snow fixed to a front storage body by rotation of a pinion. ing.
• a projection for projecting in the axial direction from an end face on the gear side is provided on a pinion for transmitting the rotational force of the armature to the gear of the engine. Things.
• FIG. 1 is a cross-sectional view showing a conventional starting motor
• FIG. 2 is a partial cross-sectional view showing a starting motor according to one embodiment of the present invention
• FIG. 3 is a cross-sectional view taken along the line III-III in FIG.

• FIG. 5 is a cross-sectional view taken along line fV in FIG.
• the electromagnetic switch ⁇ is a bottomed cylindrical plunger that supports the rod (13a) slidably in the axial direction.
• the pinion is formed by attaching a plurality of projections (9a) protruding in the axial direction to an end face on the side facing the gear (M), and the plurality of projections (:) are shown in FIG. To As shown, it is arranged radially around the rotation axis ( 7 ), and the outer circumference in the radial direction is smaller than the root circle of the pinion ( 9 ). Other configurations are almost the same as those in FIG. 1, and therefore, the same reference numerals are given and the detailed description is omitted.
• the pinion ( 9 ) can operate in exactly the same manner as that shown in Fig. 1 described above in normal use, and the engine can be started by engaging the gear (WH). .
• bra Nja (13b) is moved to the split ring (l 3 c) further leftward Te compression child and Niyotsu and closed the contacts by pressing the contact opening and closing member (not shown), Power is supplied to the armature ( 8 ) and the field winding (6). For this reason, the armature ( 8 ) is driven to rotate, and the pinion ( 9 ) is rotated by receiving this torque. As a result, the projection (9a) formed on the end face of the pinion ( 9 ) also rotates to scrape the fixed ice and snow.
• the pinion ( 9 ) rotates rightward as it rotates and shatters ice and snow.
• the pinion ( 9 ) can be easily engaged with the gear ⁇ , and the engine can be moved quickly. Can be started at any time.
• FIGS. 4 and 5 show another embodiment of the present invention, in which the projection 9a) is formed in a wedge shape.
• the good urchin projection [9 a) similarly to the above embodiment can trigger Kona ⁇ snow and ice, moreover, the strength of the protrusion () against impact received when pulverizng snow and ice Can be increased.
