摘要： A starter for an engine is equipped with a planetary gear speed reducer, a restraining mechanism, and a shock absorber which is made up of a rotary disc, a stationary disc, a case, and a load applying mechanism. The load applying mechanism applies a load to the stationary and rotary discs to develop a given degree of friction therebetween. When an excessive torque acts on the rotary disc through the internal gear, the shock absorber induces the rotary disc to rotate against the given degree of friction to absorb the torque to eliminate a physical impact to be exerted on the planetary gear speed reducer. The restraining mechanism restrains the load applying mechanism from moving in a radius direction of the internal thread to avoid undesirable engagement of the load applying mechanism with the internal thread, thereby ensuring the stability in applying the load to the stationary and rotary discs.

摘要： The rotational electric machine includes a cylindrical yoke and a field winding connected to an inner surface of the cylindrical yoke. The field winding is composed of plural formed coils, each coupled to a bobbin. The bobbin includes a first flange for insulating the formed coil from the inner surface of the cylindrical yoke, a second flange for insulating the formed coil from a supporting brim of a pole core and a pipe portion for insulating the formed coil from a boss portion of the pole core. The first flange is made all around the pipe portion while the second flange is formed to extend only in the lateral direction of the pipe portion. The bobbin is easily coupled to the formed coil by flexibly bending the bobbin. Alternatively, the bobbin or bobbins may be made by folding a bobbin sheet after placing the formed coils on the bobbin sheet.

摘要： In a starter, a one-way clutch that transmits rotation of a motor to an output shaft has a clutch inner portion. The clutch inner portion has female helical splines in an inner periphery. Also, the clutch inner portion has a stopper at a front end of the female helical splines on the side opposite to the motor. The female helical splines engage with male helical splines formed on a rear end of the output shaft so that the output shaft is slidable in an axial direction. When the male helical splines of the output shaft are brought into contact with the stopper, relative rotation of the helical splines is restricted, thereby to stop the axial movement of the output shaft.

摘要： A starter for automotive engines is provided which is equipped with a pinion carrier which is shifted by a magnetic attraction, as transmitted from a solenoid switch through a shift lever, to establish engagement of a pinion with a ring gear jointed to the engine. If thrust acting on the pinion carrier to urge the pinion against the ring gear through when the pinion has been shifted and hit the ring gear, so that the pinion is placed in abutment with the ring gear is defined as N (Newton), and the mass of the pinion carrier is defined as g (gram), a relation of g/N≦6 is met. This improves the ability of engagement of the pinion with the ring gear, thus resulting in an increased life span of the starter.

摘要： A starter for cranking an internal combustion engine is mainly composed of an electric motor and a magnetic switch having a battery bolt connected to an on-board battery and a motor bolt connected to the electric motor. When the magnetic switch is closed, electric power is supplied to the electric motor to thereby generate a rotational torque for cranking the engine. One end of a motor terminal is electrically connected to the motor bolt, and the other end is led into a motor casing through a rubber insulator supported on the motor casing. The motor terminal includes one or more curved portions having resiliency, and they are positioned between the rubber insulator and the motor bolt. Water penetration into the motor casing is prevented by the rubber insulator, and the vibration of the motor terminal is alleviated by resiliency of the curved portions.

摘要： A starter for automotive engines is provided which is equipped with a planetary gear speed reducer. The speed reducer works to reduce the speed of rotation of an electric motor and transmit it to an output shaft which is to be moved and joined to the engine through a pinion gear for starting the engine. The starter includes a thrust load sustaining mechanism made of a plate which works to sustain a thrust load arising from backward movement of the pinion gear after start-up of the engine, thereby blocking transmission of the thrust load to an armature shaft of an electric motor to avoid damage to the armature shaft.

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.
