FIELD: machine building.SUBSTANCE: elastic damping support of gas-turbine engine includes plate spring, that has elastic member with flange, its face end is connected with end of flange of casing of central drive, and rear end - with end of support casing. In the elastic member slots are made, their length is L1 = (0.6-1.8)L2, where L2 is axial length of external ring of ball bearing. The plate spring is fixed in the support casing using shoulders installed in the slots of the plate spring. The plate spring is made as single part with external ring of the ball bearing. The piston rings in the oil damper can be made supported by cylindrical bushing made with wear-resistant coating, and secured along the end of the support casing by locking using the plastically deformed shoulders. Under another option the piston rings in the oil damper are supported by internal surface of the support casing, on which the wear-resistant coating is applied.EFFECT: invention increases reliability of elastic dampening support of the gas-turbine engine.5 cl, 5 dwg |
