Abstract | To effectively prevent positional deviation and deformation of a thrust collar due to reaction force from a wheel gear.SOLUTION: A centrifugal compressor includes: a driving shaft; a wheel gear; a driven shaft rotatable around a second center shaft; a pinion gear rotatably disposed integrally with the driven shaft and engaged with the wheel gear; an impeller capable of compressing a working fluid by rotating integrally with the driven shaft; a thrust collar adjacent to the pinion gear in an axial direction and restricting axial displacement of the driven shaft by abutting on the wheel gear from the axial direction; and a plurality of bolts disposed at intervals in a circumferential direction and respectively extending in the axial direction to fix the thrust collar and the pinion gear. Each of the plurality of bolts fixes the thrust collar and the pinion gear in the axial direction in a state of being inserted from a position opposite to the wheel gear with respect to the thrust collar.SELECTED DRAWING: Figure 1
【課題】ホイールギアからの反力によるスラストカラーの位置ずれ、変形を有効に抑える。【解決手段】遠心圧縮機は、駆動軸と、ホイールギアと、第二中心軸を中心として回転可能な従動軸と、従動軸と一体に回転可能に配置され、ホイールギアと噛み合うピニオンギアと、従動軸と一体に回転することで作動流体を圧縮可能なインペラと、ピニオンギアに対して軸方向に隣接して配置され、ホイールギアに対して軸方向から突き当たることで、従動軸の軸方向への変位を拘束するスラストカラーと、周方向に間隔をあけて配置され、それぞれ軸方向に延びてスラストカラーとピニオンギアとを固定する複数のボルトと、を備え、複数のボルトの各々は、軸方向において、スラストカラーを基準として、ホイールギアと逆側の位置から挿入された状態で、スラストカラーとピニオンギアとを固定している。【選択図】図1 |
