Abstract

The invention discloses a diesel generating set shafting centering adjustment device. A base with the bottom provided with a positioning pin is arranged on a stud, a Y-shaped supporting base with a through hole in the middle is opened upwards and sits on the nut, and the upper end of the stud is inserted in the through hole. A ball pressure bearing is arranged at the bottom of the Y-shaped supporting base. A roller path on the inner surface of a movable ring is provided with an arc section, and a roller path on the inner surface of a fixed ring is provided with an inverted-V-shaped section. A gap a is arranged between the edge of the movable ring and the edge of the fixed ring, and a gap a is arranged between the fixed ring and the stud. During using, the positioning pin at the bottom of the adjustment device is arranged in a positioning hole in the center of the bottom of a main power generator shell, the nut is upwards rotated, the Y-shaped supporting base is pushed to move upwards, and a main power generator rotor shaft flange is supported till a high-elasticity diaphragm coupler at the input end of a main power generator is aligned with a diesel engine flywheel. A main power generator rotor shaft is pushed forwards and backwards in the axial direction, the gap between a main power generator rotor and a stator in the axial direction is measured, operation is easy and convenient, adjustment is accurate, and efficiency is improved.

Description

technical field [0001] The invention relates to a shafting adjustment device and method for a diesel generator set, belonging to the technical field of diesel generator set manufacturing. Background technique [0002] In a diesel generator set, the alignment of the shafting of the diesel engine and the main generator is very important. Especially for the main generator with a single support structure, the support bearing is only arranged at its output end, and the other end is only supported by the connection with the output end of the crankshaft of the diesel engine. Therefore, for a diesel generator set with a single support structure for the generator, it is a very troublesome thing to adjust the shafting alignment during assembly. The prior art method is to firstly connect the main generator casing and the diesel engine flywheel casing together through seam positioning to realize the centering assembly of the stator, and then couple the high-elastic diaphragm assembled ...
