摘要:
A starter for an internal combustion engine includes a planetary gear speed reduction mechanism, a pinion and a pinion drive shaft, a motor, a front housing having a plurality of fastening holes disposed at a circumference and a center casing having approximately the same outside diameter as the motor housing. The center housing is disposed between the motor housing and the front housing to align a motor shaft, the planetary gear speed reduction mechanism and the pinion drive shaft. The diameter of the motor housing is a maximum outside diameter of the fastening bolt less than the diameter of a circumference on which the fastening bolts are formed. Therefore, fastening bolts can be easily inserted into the fastening holes.

A starter device for starting internal combustion engines having a starter motor (20) that comprises a stator (22) and a rotor (23) as well as a drive shaft (58) as starter components (21), further having a driven element (70) that can actively be connected to the drive shaft (58) and the internal combustion engine, and having a brake device (100) that acts on the driven element (70) is proposed. The starter device is characterized in that the brake device (100) can be actuated by means of at least one starter component (21) by switching on the starter motor (20).

An engine starting apparatus includes a starter motor rotating when the engine is started, a wedge roller speed reduction mechanism adapted to output a rotation of the starter motor from an output shaft at a reduced speed and to cut off power transmission between the starter motor and the output shaft when the rotational speed of the output shaft exceeds the reduced speed, a pinion gear provided on the output shaft in such a manner as to rotate together with the output shaft and to move axially over the output shaft between an engagement position where the drive gear is mesh engaged with a ring gear and a disengagement position where the pinion gear is disengaged with the ring gear, and a magnet switch for driving the pinion gear to the engagement position when the engine is started and to the disengagement position after the engine has been started.

A starter motor includes an intermediate gear engaging with and driven by a pinion connected to an output shaft of an electrical motor. The intermediate gear is coupled to the pinion by means of a retainer to be shifted in its axial direction together with the pinion. The intermediate gear engages with a ring gear of an engine to crank up the engine when it is shifted in the axial direction. The retainer is connected to a pinion boss by forcibly enlarging a resilient opening of its groove, and the resilient opening recovers its original position after the retainer is connected to the pinion boss. In this manner, the retainer is prevented from dropping off from the pinion boss during an assembling process of the starter motor. The retainer is made of resin to have an enough thickness to secure a sufficient mechanical strength.

A starter motor for cranking an internal combustion engine includes an electric motor, a planetary gear device for reducing a rotational speed of the electric motor, and a shock-absorbing device that absorbs excessive impact transmitted from the engine to the starter motor. The planetary gear device has an annular member contacting a separating plate that separates the planetary gear device from the electric motor. A depressed portion such as a circular groove is formed on an axial end surface of the annular member. Lubricant retained in the depressed portion lubricates the end surface that rotates relative to the separating plate to absorb the excessive impact transmitted from the engine, and thereby abrasion wear of the end surface is suppressed.

A starter for a piston aircraft engine is constructed by placing the pinion-gear and drive clutch, the engagement solenoid and the driving motor in a linear arrangement, the motor driving the clutch via a geared shaft passing by the engagement solenoid. Such construction provides minimum diameter for a solenoid-engaged piston aircraft engine starter in order to fit the available space on existing aircraft originally designed to be equipped with centrifugally-engaged starters.

To reduce abrasion of the pinion and the ring gear, a coil spring and a plate are arranged between the inner circumference of the plunger and the output shaft. The plate is adapted to the rear end of the thrust spline of the over-running clutch to transmit the elastic force of the coil spring to the thrust spline.

To fully secure the precision around an output shaft, an electromagnet is axially held in position between a center bracket and a front bracket which form an enclosing member for a starter.
