Title: Motor for starter
Inventor: MORISHITA AKIRA
IPC: H02K31/02
Filed: 1987-06-15
Abstract: PURPOSE:To miniaturize a motor with less heat emission, by using a rotating shaft of a single-pole DC motor as an input shaft of a high-speed ratio gear by the use of a flexible gear. CONSTITUTION:A rotor disk 15 receives power to rotate in high speed with the magnetic field going through the rotor disk 15 from each permanent magnet 19 and 20 and with the current flowing through a core 16. This rotating force is transmitted from a rotating shaft 12 to an elliptic cam 23 to rotate it inside a ball bearing 24. As the major axis of this elliptic cam rotates, a flexible gear 25 is bent in accordance with its rotation and changes the position to mesh with a ring gear 28, a corresponding point to the major axis, in accordance with the rotating direction. Since the number of teeth of the elliptic cam 23 closely approximates to that of the ring gear 28 in value, the flexible gear 25 rotates at a large reduction gear ratio opposite to the rotating direction of the elliptic cam 23. This rotating force is transmitted to a body of rotation 26 and is outputted from its output shaft 26a.
