Japanese Patent JP2016183752
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a speed increasing gear which inhibits an oil from drying up near center parts of contact portions, and to provide a centrifugal compressor including the speed increasing gear.SOLUTION: A speed increasing gear 14 includes: a ring part 62 which rotates in conjunction with rotation of a low speed side shaft 11; a high speed side shaft 12 disposed at the inner side of the ring part 62; and a first roller 71 provided between the ring part 62 and the high speed side shaft 12 and contacting with the ring part 62 and the high speed side shaft 12. In the first roller 71, a center part 71d elastically deforms in a radial direction of the first roller 71 more easily than both end parts 71b, 71c of the first roller 71 which are end parts when viewed in a rotation axis direction Z.SELECTED DRAWING: Figure 1
