Title:
遊星変速機において動力を分担する歯車装置
Document Type and Number:
Japanese Patent JP4782341
Kind Code:
B2
Abstract:
A planetary gear transmission has two or more planetary gear sets (2a, 2b, 2c, 2d) in the gear train. Each planetary gear set comprises a sun gear (1) mounted on a sun shaft (5) with the sun gear (1) engaging a plurality of planet gears (2) mounted on a planet carrier (4) with the plurality of planet gears (2) engaging a ring gear (3) mounted on the transmission housing (7). Each gear of the planetary gear transmission is a helical cut gear. Sun gears (1a, 1b, 1c, 1d) and or ring gears (3a, 3b, 3c, 3d) are mounted for axial movement with respect to the transmission. Thrust imbalances on the sun gears (1a, 1b, 1c, 1d) and or ring gears (3a, 3b, 3c, 3d) resulting from uneven loading and the helical cut result in sun gears (1a, 1b, 1c, 1d) and or ring gears (3a, 3b, 3c, 3d) moving in the axial direction to eliminate the thrust imbalances and thereby resulting in equal loading or power sharing amongst the planetary gear sets (2a, 2b, 2c, 2d).
