- Patent Document 4 it is possible to use different grease yarns and composites for rolling bearings. Different grease compositions leak and mix and harden or soften and deteriorate. It is preferable to use the same grease composition for the one-way clutch and the rolling bearing.
- the engine room where the alternator and the like are installed is under a wide range of temperature conditions from low temperature to high temperature.
- the internal temperature rises with the sliding friction of the one-way clutch and the rotation of the rolling bearing.
- the grease composition must have fluidity and heat resistance at low temperatures.

- FIG. 1 is a cross-sectional view showing a configuration of a rotation transmission device with a built-in one-way clutch according to the present embodiment.
- FIG. 2 is a diagram showing a state of a reciprocating friction test.
- FIG. 1 is a cross-sectional view showing a configuration of a one-way clutch built-in rotation transmission device of this embodiment incorporated in an alternator for an automobile.
- This one-way clutch built-in rotation transmission And a sleeve (rotating member) 11 arranged concentrically with the pulley 12 on the inner diameter side of the pulley 12, an outer peripheral surface 11a of the sleeve 11, and an inner peripheral surface 1 of the pulley 12.
- Rolling bearings 2 and 2 and a one-way clutch 3 provided between 2a and 2a.
- the outer circumferential surface of the pulley 12 is formed with irregularities so that the cross section along the axial direction is corrugated, and an endless belt (V belt) (not shown) is stretched over the irregular surface.
- the endless belt travels by driving an accessory driving device (not shown), and the pulley 12 rotates as the endless belt travels.
- the sleeve 22 is a cylindrical member that is externally fixed to the rotating shaft S of the alternator, and transmits the rotational force to the rotating shaft S.
- a large-diameter portion 11A having a large outer diameter is formed at the intermediate portion in the axial direction of the sleeve 11, and a protrusion 11B having a large outer diameter is formed at one axial end of the large-diameter portion 11A.
- a rotating rotor for power generation is fixed to the rotating shaft S, and the alternator generates electricity by the rotation of the rotating shaft S.
- Each rolling bearing 2 is a deep groove ball bearing including an inner ring 21, an outer ring 22, a ball (rolling element) 23, a cage 24, and a pair of seals 25, 25, and a pair between the inner ring 21 and the outer ring 22.
- the sealed space closed by the seals 25 and 25 is filled with the grease composition G of the present invention. The composition of this grease composition G will be described later.
- the one-way clutch 3 is provided adjacent to a pair of the rolling bearings 2 and 2 that are fitted to the axially intermediate portion of the sleeve 11, that is, both ends of the axial direction.
- the configuration includes a clutch inner ring 31, a clutch outer ring 32, a plurality of rollers 33 disposed between the outer peripheral surface of the clutch inner ring 31 and the inner peripheral surface 32b of the outer ring 32 for clutch, and the roller 33.
- a clutch retainer 34 for holding, and between the outer peripheral surface of the clutch inner ring 31 and the inner peripheral surface 32b of the outer ring 32 for clutch, the same grease composition G as that enclosed in the rolling bearings 2 and 2 is provided. Filled.
- the clutch inner ring 31 is externally fitted to the large-diameter portion 11A of the sleeve 11, and the outer peripheral surface thereof is formed with the same number of recesses 31a as the rollers 33 on the normal cylindrical surface at equal intervals in the circumferential direction. It is the cam surface.
- the outer ring 32 for clutch is fitted to the inner peripheral surface of the pulley 12 facing the inner ring 31 for clutch, and the inner peripheral surface thereof is a normal cylindrical surface. A pair of ridges 32a are formed!
