Definitions

  • the pinion regulating means need only to hold the pinion with the small force required to regulate the rotation of the pinion, the pinion regulating means can be moved to the pinion side by a magnet switch by way of a cord-shaped member, and the freedom with which the magnet switch can be disposed can be increased.
  • the pinion regulating means itself can attain pinion return prevention when the pinion has meshed with the ring gear, and the number of parts can be made small and the assembly can be simplified.
  • the cord-shaped member 680 is transmitting means for transmitting the movement of the magnet switch 600 to the regulating claw 231, and the movement of the magnet switch 600 pulls the rotation regulating portion 232 downward and causes the regulating claw 231 to engage with the projections 214 on the flange 213 of the pinion gear 210.
  • the return spring portion 233 bends.
  • the center bracket 360 is shown in detail in Fig. 4 through Fig. 6 and is disposed inside the rear end of the housing 400.
  • the housing 400 and the center bracket 360 are linked by a ring spring 390 having one end engaged with the housing 400 and the other end engaged with the center bracket 360 and are arranged in such a way that the rotational reaction received by a clutch inner 352 constituting the overrunning clutch 350 is absorbed by the ring spring 390 and the reaction is not directly transmitted to the housing 400.
  • the planet carrier 330 is provided at its rear end with a flange-like projecting portion 331 which extends radially in order to support the planetary gears 320.
  • Pins 332 extending rearward are fixed to this flange-like projecting portion 331, and these pins 332 rotatably support the planetary gears 320 by way of metal bearings 333.
  • armature coils 530 For the armature coils 530, in this embodiment shown in detail in Fig. 7, multiple (for example 25) upper layer coil bars 531 and the same number of lower layer coil bars 532 as these upper layer coil bars 531 are used, and 2-layer-winding coils wherein the respective upper layer coil bars 531 and the lower layer coil bars 532 are stacked in the radial direction are employed.
  • the upper layer coil bars 531 and lower layer coil bars 532 are paired, and the ends of the upper layer coil bars 531 and the ends of the lower layer coil bars 532 are electrically connected to constitute ring-shaped coils.
  • the upper layer coil bars 531 are made of a material having excellent electrical conductivity (for example copper), and are each provided with an upper layer coil arm 533 which extends axially in parallel with the fixed poles 550 and is held in the outer sides of slots 524 and two upper layer coil ends 534 which are bent inward from both ends of the upper layer coil arm 533 and extend in a direction orthogonal to the axial direction of the armature shaft 510.
  • a material having excellent electrical conductivity for example copper
  • the magnet switch 600 is structured inside a magnet switch cover 640 which is cylindrical and has a bottom and is made from magnetic parts (for example made of iron).
  • the magnet switch cover 640 is for example a pliable steel plate press-formed into a cup shape, and in the center of the bottom of the magnet switch cover 640 there is a hole 641 through which the plunger 610 passes movably in the vertical direction. Also, the upper opening of the magnet switch cover 640 is closed off by a stationary core 642 made of a magnetic body (for example made of iron).
  • the stationary core 642 consists of an upper large diameter portion 643, a lower middle diameter portion 644, and a still lower small diameter portion 645, and the stationary core 642 is fixed in the upper opening of the magnet switch cover 640 by the outer periphery of the large diameter portion 643 being caulked to the inner side of the upper end of the magnet switch cover 640.
  • the upper end of an attracting coil 650 is fitted around the middle diameter portion 644.
  • the upper end of a compression coil spring 660 which urges the plunger 610 downward is fitted around the periphery of the small diameter portion 645 of the stationary core 642.
  • the lower surface of the plunger 610 is provided with a recess portion 682 which accommodates a sphere 681 provided at the rear end of the cord-shaped member 680 (for example a wire).
  • a female thread 683 is formed on the inner wall of this female thread 683.
  • a fixing screw 684 which fixes the sphere 681 in the recess portion 682 is screwed into this recess portion 682. This fixing screw 684 is also used to perform adjustment of the length of the cord-shaped member 680, by adjusting the extent to which the fixing screw 684 is screwed into the female thread 683.
  • the compression coil springs 914 are disposed radially outward with respect to the axial direction of the plunger 610 of the magnet switch 600.
  • the terminal bolt 620 is a steel bolt which passes through the end frame 700 from the inside and projects from the rear of the end frame 700 and has at its front end a head portion 621 which abuts with the inner surface of the end frame 700.
  • the terminal bolt 620 is fixed to the end frame 700 by a caulking washer 622 being attached to the terminal bolt 620 projecting rearward of the end frame 700.
  • a copper fixed contact 630 is fixed to the front end of the terminal bolt 620 by caulking.
  • the brush holder 900 as well as the roles of separating the inside of the yoke 501 and the inside of the end frame 700 and rotatably supporting the rear end of the armature shaft 510 by way of the brush holder bearing 564, also fulfills the role of a brush holder, the role of holding the magnet switch 600, and the role of holding a pulley 690 which guides the cord-shaped member 680.
  • the brush holder 900 has a hole portion not shown in the drawings through which the cord-shaped member 680 passes.
  • the lead wires 910a of the upper brushes 910 are electrically and mechanically joined by a joining method such as welding or caulking to the upper movable contact 612 which is moved by the magnet switch 600.
  • the lead wires 910a of the lower brushes 910 are caulked and thereby electrically and mechanically joined to a concave portion 920 formed in the rear surface of the brush holder 900.
  • a pair of lower brushes 910 are provided, one lead wire 910a is connected to the pair of lower brushes 910, and the middle of the lead wire 910a is caulked in the concave portion 920 formed in the rear surface of the brush holder 900.
  • the magnet switch 600 in embodiment 1 is disposed parallel to the motor 500 and the pinion rotation regulating member 230 is operatively linked with the magnet switch 600 through the wire 680.
