Title:
FRICTION ROLLER TYPE REDUCTION GEAR AND REDUCTION GEAR UNIT USING THE SAME
Document Type and Number:
Japanese Patent JP2018189206
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a friction roller type reduction gear that can obtain high power transmission efficiency without being influenced by centrifugal oil pressure, can reduce the axial length of the reduction gear itself, and never lowers mountability on a vehicle, and a reduction gear unit using the same.SOLUTION: A friction roller type reduction gear comprises a sun roller 15 consisting of a movable sun roller element 35 and a fixed sun roller element 37, a ring roller 17, a plurality of intermediate rollers 19, and a loading disk 24. Rolling contact surfaces of the sun roller 15 and intermediate roller 19 are inclined surfaces increasing in radius distance to an input shaft 11 from opposite-side end faces 41, 43 to outside end faces 45, 47 of the sun roller element. A main oil chamber 89 is formed between the movable sun roller element 35 and loading disk, and a canceller oil chamber 91 which generates axial force for reducing the centrifugal oil pressure is formed between the movable sun roller element 35 and fixed sun roller element 37.SELECTED DRAWING: Figure 2
