Title:
PARALLEL SHAFT DIFFERENTIAL GEAR DEVICE
Document Type and Number:
Japanese Patent JP3196997
Kind Code:
B2
Abstract:

PURPOSE: To prevent earlier wear of a thrust washer by providing a holding member on the inner side of the thrust washer, and forming an oil holding space in which the lubricating oil is held and a part of which is opened to the outer surface of the holding member in this holding member.
CONSTITUTION: When a housing 1 is rotated, an axle spacer 7 (holding member) is rotated by the friction between sun gears 2, 2. Then, the lubricating oil filled in the space comes out onto the outer circumferential surface of the axle spacer 7 due to the centrifugal force. This lubricating oil enters the space between a center washer 6 and each end face of the sun gears 2, 2. The center washer 6 prevents earlier wear due to the sliding contact between the sun gears 2, 2. Because the lubricating oil held by the axle spacer 7 is supplied, no hole to hold the lubricating oil is required in the center washer 6. Thus, the area of contact of the center washer 6 with the sun gears 2, 2 is not reduced.
