DIFFERENTIAL GEAR
Document Type and Number:
Japanese Patent JP2017160943
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform an efficient lubrication at a first transmission mechanism of a differential gear comprising: a first transmission member having a first axis as a center axis; an eccentric rotating member in which a hollow first output boss rotatable around the first axis and an eccentric shaft part having a second axis eccentric from the first axis being applied as a center axis integrally connected; a second transmission member oppositely arranged against the first transmission member and rotatably supported at the eccentric shaft part; a third transmission member having a hollow second output boss rotatable around the first axis and oppositely arranged against the second transmission member; the first transmission mechanism between the first and second transmission members; and a second transmission mechanism between the second and third transmission members.SOLUTION: One of fitted surfaces between a first hub HB1 of a transmission case C and a first drive shaft S1 fitted to and supported at the hub is provided with a spiral groove 18 capable of sucking lubricant oil in a transmission case 1, and an oil passage P1 for communicating groove outlets with an inner peripheral side of a first transmission mechanism T1 is arranged between the transmission case C and an eccentric rotating member 6.SELECTED DRAWING: Figure 1
