Title:
GEAR TRANSMISSION MECHANISM
Document Type and Number:
Japanese Patent JP3058020
Kind Code:
B2
Abstract:
PURPOSE: To perform reliable transmission of revolution of a planetary gear and rotation from a motor to a mating gear meshed with the planetary gear, in a gear transmission mechanism having a sun gear and a planetary gear.
CONSTITUTION: When rotation from a motor is transmitted to a second sun gear g4 through a first sun gear g3, a first planetary gear g5 performs revolutions through operation of a wave washer 3 until mesh with a gear g7 is effected. When the gear g7 is meshed, revolution of the first planetary gear g5 is regulated by a first stopper member 5. Rotation torque exerted by the second sun gear g4 exceeds load torque on rotation by the wave washer 3, the first planetary gear g5 is started to rotate and rotation of the motor M is transmitted to the gear g7.
