20080227556 | Engine starter having improved helical spline structure for ensuring reliable engagement between output shaft and pinion gear - A starter includes a motor, an output shaft driven by the motor, a pinion gear provided on the output shaft, and a shifter. The output shaft has first helical splines that are formed on an outer periphery of the output shaft. The pinion gear has second helical splines that are formed on an inner periphery of the pinion gear to engage with the first helical splines. The shifter shifts the pinion gear along the output shaft through the engagement between the first and second helical splines, thereby bringing the pinion gear into mesh with a ring gear of an engine. Further, in the starter, X09-18-2008 | |

20090026896 | Starter for engines and its starting circuit - The starter has a system of pushing the pinion gear in the direction of the anti-motor side by using the attracting power of the electromagnetic switch via the shift lever. The switch coil of the electromagnetic switch is constituted of one coil that is electrically separated from the motor circuit. The mass of pinion gear is set to 100 g or less, the switch extrusion power stored in the drive spring is set to 70N (Newton) or less, and the operation current of the electromagnetic switch is set to 12 amperes or less. With this starter, since the switch coil and the motor circuit can be electrically separated, the terminal for connection for connecting the conventional attracting coil and conventional “M terminal bolt” can be abolished. Further, by setting the operation current of the electromagnetic switch 10 to 12 amperes or less, it is possible to control the operation current directly by the ECU. | 01-29-2009 |
20090027147 | Biaxial type of starter for starting internal combustion engine - A starter for starting in-vehicle internal combustion engines comprise a motor, an electromagnetic switch and an electrically conductive connection member. The electromagnetic switch comprises first and second fixed contacts, a movable contact, an electromagnet moving back and forth to the movable contact to electrically connect and disconnect the first and second fixed contacts, and a cover covering the first and second contacts and movable contact. The predetermined direction is parallel to an armature provided in the motor. The electromagnet is provided with only a single coil generating a drive force for moving the movable contact. A connection member is arranged to be through the casing and the cover and electrically connects a brush of the armature in the motor and the second fixed contact in the switch. The connection member includes an end part arranged in the casing of the switch. This end part functionally provides the second fixed contact. | 01-29-2009 |
20090133516 | Starter motor having seal plate to seal bearing box formed in end frame - A starter motor is disclosed which includes: 1) a hollow yoke having an open end; 2) a magnetic field system provided on an inner periphery of the yoke; 3) an armature surrounded by the magnetic field system with a predetermined gap therebetween, the armature having an armature shaft; 4) an end frame that closes the open end of the yoke and has a bearing box formed therein, the bearing box being recessed inward of the yoke from an end face of the end frame and having an open end on the end face of the end frame, the bearing box also having a bearing disposed therein to rotatably support an end portion of the armature shaft; and 5) a flexible seal plate that is attached on the end face of the end frame to hermetically seal the open end of the bearing box formed in the end frame. | 05-28-2009 |
20090145250 | Starter with compact structure - A starter is disclosed as having a housing carrying thereon a motor, and a pinion moving body including a pinion gear, operative to mesh with a ring gear of an engine to transfer a rotational force of the motor thereto, and a pinion shielding member connected to the pinion gear at a front end thereof. The pinion shielding member has an outer circular periphery, having an outer diameter greater than the diameter of the addendum circle of the pinion gear, and a bottomed cylindrical configuration formed with a hollow portion having a front opened end and a closed rear end. Further, a clearance between an inner circumferential periphery of the nose portion and the outer circular periphery of the pinion shielding member is minimized to avoid interference between the nose portion of the housing and the pinion shielding member. | 06-11-2009 |
20090167102 | Starter motor - In a starter motor equipped with a shock absorbing device, a disk spring is placed between a bottom part of a cylindrical casing and one side of a disk stack structure composed of rotatable disks and fixed disks which are alternately stacked. Caulking parts formed at an opening end of the cylindrical casing are bent toward the inner diameter side of the cylindrical casing in order to push the disk spring toward the bottom part side of the cylindrical casing through the disk stack structure. The disk spring accumulates reaction force (or elastic force) by the caulking. The reaction force accumulated in the disk spring pushes the disk stack structure to the axial direction of the cylindrical casing. The structure of the shock absorbing device can supply a uniform load to the disk spring, and provides a stable shock absorbing capability. | 07-02-2009 |
20100225189 | Starter - In a starter with which a pinion movable body with which a pinion gear and a one-way clutch were united moves on an output shaft, a holder is attached to the one-way clutch. A seal component having the shape of a ring is provided so that an end of an outer circumference of the seal component is fixed to a nose part of a housing and an end of an inner circumference of the seal component slidably contacts an outer circumferential surface of the holder. The holder is provided so that relative rotation to the one-way clutch is possible. Since the holder doesn't rotate relative to the housing, wear of a seal component is reduced compared with the case where the seal component contacts the one-way clutch which rapidly rotates whereby the sealability preventing a foreign substance or water from infiltrating into the inside of the starter can be maintained. | 09-09-2010 |
