Abstract

PURPOSE:To obtain a starter device of small size and of simple structure in an engine with its output shaft eqipped with a flywheel, by integrating the flywheel into its starting motor as a component accumulating rotation of the engine shaft as a inertial force. CONSTITUTION:When starting an internal combustion engine E, a coil 9 over a stator 8, installed at a prescribed interval within a housing 1 which is an integrated part of the engine E, is electrified, electro magnetic force is generated between a magnet 7 positioned on the flywheel 5 constituting a rotor 6, facing above above mentioned stator 8 and the coil, thus rotating the rotor 6. This rotational power will then drive a crank shaft 4 generating reciprocating action of a piston 2 through conrod 3 leading into a cranking movement. After the engine is started and electricity for the coil 9 is turned off, the above starting action is terminated and rotational power of the crank shaft 4 is accumulated in the flywheel 5 as a inertial force.

The present invention relates to an internal combustion engine starting device designed to ensure -.

[Prior Art] Conventionally, internal combustion engines have been started using an independent starter. This starter has a starter motor and a pinion C and 4fJ that are rotated by the motor. When the piston rotates, the pinion slides in the axial direction due to its own inertia, and is attached to the outer periphery of the fuller r, j, and eel of the internal combustion engine. There is a resistance that meshes with the provided link gear. In this conventional starter, the movement of the vinyl A"N ring 1" 17 getting stuck and coming off due to (1) timing mismatch with the ring gear), (2) wear on itself, etc. This caused deterioration of the meshing characteristics of ring gear A7 and caused noise.

For example, in the former (1), the pinion is attached to ring gear A7.
1) The teeth do not mesh with each other, and the teeth collide with each other on the end faces, causing noise.
Force can damage at least one side. In the latter case (2), when the pinion disengages (retreats), the so-called early escape causes the internal combustion engine to start completely, but the pinion retreats even when the internal combustion engine completely starts and the internal combustion engine There are many practical problems that need to be solved.
