摘要： The device comprises a fixed wheel (1) which has a sun gear axle (2) inserted coaxially through it. A number of planet gears (3) are situated between an inner peripheral surface of the fixed wheel and an outer peripheral surface of the sun gear axle. A carrier (4) has pockets for supporting the rolling planet gears. Each pocket has a first upper surface in sliding contact along contact areas (D) with the outer surface of the planet gears and a second upper surface opposite the first. The carrier has elements for reducing the friction between the contact areas of the planet gears and the contact surfaces (C) of the sun gear axle outer surface.

摘要： PROBLEM TO BE SOLVED: To contact a planetary roller and a carrier with each other in an optimal condition, and improve a lubricating condition of a contact part of the planetary roller and an input shaft by contacting/guiding the carrier with/to an outer peripheral surface of the input shaft. SOLUTION: An oil containing member 5 is arranged between an inner circumferential surface of a carrier 3 and an input shaft 1, and the carrier 3 is contacted with and guided to the input shaft 1 through the oil containing member 5. For example, the oil containing member 5 is formed by impregnating lubricating oil into a porous material formed of a sintered material, or by compressing a mixture of resin and lubricating oil by heating and cooling, and an inner peripheral surface of the carrier 3 is installed so as to contact with the input shaft 1 or the input shaft 1 and a planetary roller 2. Therefore, looseness of the carrier 3 is eliminated, and the axis of the carrier 3 always coincides with the axis of the input shaft 1, and operation can be performed in a condition where a contact surface pressure value is lowest between the planetary roller 2 and the carrier 3. Lubricating oil of the oil containing member 5 is supplied to an outer peripheral surface of the input shaft 1, and a lubricating condition of a contact part of the planetary roller 2 and the input shaft 1 is improved.

摘要： PROBLEM TO BE SOLVED: To dispense with side plates to be attached to both sides of a fixed wheel by extending both ends of the fixed wheel in the axial direction, and an inner flange for guiding a planetary roller to the revolutional direction at the inner dia. part of both ends extended. SOLUTION: Both ends of a fixed wheel 4 are respectively extended in the axial direction in correspondence with almost the thickness of side plate, and at the inner dia. part of the extended ends annular inner flanges 4a are respectively formed. This flange 4a guides a planetary roller 2 to the revolutional direction through a slightly small gap in the axial direction. Accordingly, side plates are unnecessary on both sides of the fixed wheel 4. With the formation of the flange 4a at right angles to the axis of the wheel 4, the perpendicularity to the roller 2 can be ensured easily, thereby preventing generation of skew in the roller 2.
