Abstract

The invention discloses a method for installing an engine rotor shaft, a connecting ring and blanking covers, and relates to the technical field of engines. The method for installing the engine rotor shaft includes the following steps that S1, the rotor shaft is installed on the connecting ring; S2, the front blanking cover is arranged on the rotor shaft in a sleeving mode and is fixedly connected with the connecting ring; S3, a first bearing is assembled on the rotor shaft, so that the rotor shaft, the front blanking cover, the first bearing and the connecting ring form an assembly; a bearing case is installed on an intermediate case, and a second bearing is assembled on the bearing case; S4, the assembly is moved to make the front blanking cover attached to the bearing case; and S5, the connecting ring is removed; and meanwhile, the rear blanking cover and the bearing case are fixedly connected. The connecting ring is used for the installing method of the engine rotor shaft. The blanking covers are also used for the installing method of the engine rotor shaft. The method has the beneficial effects that the demand of a high speed engine can be met, and rotors and stators can be installed quickly.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine rotor shaft installation method, a connecting ring and a blocking cover. Background technique [0002] The engine generally includes a rotor and a stator. The rotor includes a rotor shaft and an integral blisk, and the stator includes a front block cover, a rear block cover, a bearing casing and an intermediate casing. The stator is connected and fixed to the aircraft or ship, similar to grounding, to provide support for the rotor; the rotor is supported on the stator through bearings, the inner ring of the bearing is sleeved on the rotor shaft of the rotor, and the outer ring of the bearing is installed on the stator. The usual assembly is that the rotor is assembled in sequence with discs and blades at all levels, or the overall blisk and rotor shaft; the stator is assembled with casings, stator blades and inner rings at various levels in sequence. The same is true a...
