LUBRICATING OIL FEEDING DEVICE OF TRANSMISSION

PROBLEM TO BE SOLVED: To distribute the feeding oil amount according to the lubricating oil amount for a plurality of lubricating oil passages sharing a shaft end oil chamber. SOLUTION: A lubricating oil feeding device of a transmission comprises a housing 3 to support a rotary shaft 20 and a rotary shaft, a lubricating oil passage 110 in a first shaft, having a first shaft end opening 115 at the shaft end surface of the rotary shaft and extending in the shaft, a lubricating oil passage 120 in a second shaft, having a second shaft end opening 125 at the shaft end surface and extending in the shaft end, and a shaft end oil chamber 130 formed between the housing 3 and the shaft end of the rotary shaft to cover a shaft end surface 20f. The lubricating oil feeding device of the transmission feeds the lubricating oil fed from an oil pressure feeding source into the shaft end oil chamber 130 via the lubricating oil passages in the first and second shafts to first and second portions (27, C2) to be lubricated on the rotary shaft 20. The first shaft end opening 115 and the second shaft end opening 125 are formed in the different radial positions in the axial direction of the rotary shaft 20. COPYRIGHT: (C)2007,JPO&INPIT
