Title:
DRIVE TRANSMISSION, IMAGE FORMING APPARATUS USING THE SAME, AND PROCESS CARTRIDGE
Document Type and Number:
Japanese Patent JP2009069556
Kind Code:
A
Abstract:

To provide a rotational drive transmission satisfying simultaneously rotational precision in a plurality of rotors, and positional precision in the fellow rotors.

The first rotor drive system is constituted of a drive motor 301, a gear 302 for decelerating a driving force of the motor, an involute spline joint 304, and a shaft support member 303 fixed onto a transmission body. The second rotor drive system is constituted of deceleration trains 305-308, and an involute spline joint 309. The involute spline joint 309 is journaled by the shaft support member 303 the same to that of the involute spline joint 304. A rotational drive input by the drive motor 301 is transmitted to the deceleration gear 302, and the involute spline joint 304 coaxial to the gear 302 is driven, in the first rotor drive system. The involute spline joint 304 in a drive unit side is engaged by meshing with an involute spline joint in a driven side, so as to transmit the rotational drive.
