変速機および駆動ユニット
Document Type and Number:
Japanese Patent JP6727058
Kind Code:
B2
Abstract:
The invention provides a transmission and a driving unit capable of transmitting driving force in the transmission with great efficiency. The transmission (10) is provided with a sun wheel (1), multiple first planetary rotators (2a), multiple second planetary rotators (2b), a carrier (3a), an inner ring (4), a housing (5) and a shaft body (3b). In the axial direction, the multiple first planetaryrotators (2a) are disposed on one side of the multiple second planetary rotators (2b). Multiple planetary rotators (2a, 2b) are capable of self-rotating and held on the carrier (3a) by revolving relative to a central axis (C). The carrier (3a) and the multiple planetary rotators (2a, 2b) revolve around the center of the central axis (C). When a motor (50) drives the sun wheel (1) to rotate, rotation of the sun wheel (1) is transmitted to the shaft body (3b) after being decelerated by the multiple planetary rotators (2a, 2b) and the carrier (3a).
