2 Bendex type drive mechanism
Armature shaft with the help of a key. This unit has three bangles cut and one sleeve. A Bendex pinion is fitted on
top of the sleeve, on which teeth are made according to the flywheel ring gear and on the inside the bangle is cut
according to the sleeve.
Antidrift spring is used to prevent the pinion from colliding with the flywheel. When the starting switch is turned
on, the armature starts rotating. As the armature rotates, the pinion fitted on its shaft slips on the sleeve due to
centrifugal force and moves forward and does not establish connection with the armature shaft and the flywheel.
In this way the self also starts rotating the flywheel. As soon as the starting switch is closed or the engine is started,
due to reverse pressure, the pinion comes back into place, like a nut-bolt. In this way the connection between
the flywheel and the self-starter is broken. The structure of the Bendex drive mechanism is shown in the figure.
