Title:
VARIABLE TORQUE MOTOR AND TORQUE VARIABLE STRUCTURE OF MOTOR
Document Type and Number:
Japanese Patent JP2021136855
Kind Code:
A
Abstract:
To provide a variable torque motor that can take out two types of outputs such as high-speed rotation low torque and low-speed rotation high torque, by one motor and a single output shaft while suppressing an increase in size of the entire mounted device.SOLUTION: A variable torque motor uses a mysterious planetary gear mechanism 2 as a speed reducer 2, and a clutch 1 is provided between a motor body 9 and a speed reducer 2. The mysterious planetary gear mechanism 2 includes: a sun gear 3 that rotates integrally with a motor shaft 8; a planetary gear 4 that revolves around the sun gear 3 while rotating; a second internal gear 6 that meshes with the planetary gear 4 and is subjected to action by the clutch 1; a first internal gear 5 that meshes with the planetary gear 4 and has a different number of teeth from the second internal gear 6, and rotates integrally with an output shaft 11; and a carrier 7 that accommodates the planetary gear 4 and is subjected to action by the clutch 1.SELECTED DRAWING: Figure 1
