FIELD: machine building.SUBSTANCE: scroll compressor (1) includes weight (81, 82, 83) to reduce deformation created by fluid, it reduces deformation of crankshaft (40) in direction of load due to fluid. Weight (81, 82, 83) to reduce deformation due to fluid includes top weight (81) to reduce deformation due to fluid, its centre of gravity is located at distance from centre of axis of main shaft (41) in direction opposite to direction of load due to fluid, middle weight (82) to reduce deformation due to fluid, its centre of gravity is located at distance from centre of axis of main shaft (41) in the same direction as direction of load due to fluid, and bottom weight (83) to reduce deformation due to fluid, its centre of gravity is located at distance from centre of axis of main shaft (41) in direction opposite to direction of load due to fluid. Top, middle and bottom weights (81, 82, 83) to reduce the deformation due to fluid are balanced by each other.EFFECT: reduced degree of ultimate strength of bearing in case, when fluid pressure is high.6 cl, 8 dwg |
