  • Patent number: 4909200
    Abstract: A starter for a general purpose engine has a starting motor with an armature shaft disposed in axial alignment with the engine crankshaft. The armature shaft is coupled via a planetary gear set to an intermediate shaft, also in axial alignment with the engine crankshaft, which is coupled to the engine crankshaft via an overrunning clutch. This clutch permits the engine crankshaft to overrun the intermediate shaft after the engine is started. Having a pull rope wound thereon, a starting reel is rotatably and coaxially supported over the intermediate shaft. A centrifugal clutch normally holds the starting reel disconnected from the engine crankshaft and, upon rotation of the starting reel as a result of exertion of a manual pull on the pull rope, drivingly connects the starting reel to the engine crankshaft.

The shell comprises a flange which is fixed to the base plate of the starter by the screws which mount the starter to the casing of the engine. For this purpose, bushings are disposed between the flange of the shell and the metal base plate of the starter so that the non-rigid support is not subjected to the compressive stresses exerted by the screws. The invention is more particularly applicable to the automobile industry.

  • Patent number: 4464576
    Abstract: A starter drive for internal combustion engines. The starter drive is mounted within the starter housing and connected to the motor driven shaft. The shaft has a screw thread formed thereon near the armature of the starter and a cylindrical end portion. A screw sleeve member cooperatively engages the screw thread of the motor driven shaft. A ring armature member is centrally mounted to the threaded screw member. A unidirectional clutch member connects the screw sleeve member, the ring armature member and the pinion gear. An engaging member holds the ring armature member to the starter housing when the pinion gear is advanced axially along the motor driven shaft by the rotation of the motor when the motor is activated. Thus, the pinion gear engages the engine ring gear such that the pinion gear is held in mesh with the ring gear and the total motor torque is transmitted to the ring gear until the motor is deactivated.

  • Patent number: 4455490
    Abstract: An apparatus combination for improving the starting mode of a starter for an internal combustion engine is disclosed. The combination comprises a supporting means effective to support the starting motor armature, both for rotary movement about an axis within the field winding and for axial movement in response to the axially directed magnetic forces of the winding. Friction means are employed to sequentially engage each of two conical surfaces carried by the member to be driven by the starter motor, such sequential engagement being in response to the axial movement of the armature. Means are also disclosed to assist the frictional engagement between the conical surfaces of the driven member by use of a resilient ring which allows full metal-to-metal contact between the friction means and driven member, but also provides extended interengagement with the friction means by distortion of the ring along a tangent to the friction means.
