A connection structure of a diesel engine and a main generator

Abstract

The invention discloses a connection structure for a diesel engine and a main power generator. The connection structure comprises a main power generator shell, a main power generator rotor, a shaft flange, a diesel engine shell, a diesel engine flywheel, an elastic coupling joint, a flange, a shaft flange split shaft part and a flange part, wherein the flange part is connected to the right end face of the main power generator rotor; the right end of a shaft part is connected into the flange in a sleeving manner; the right end of the elastic coupling joint is connected with the diesel engine flywheel; the connection structure further comprises a bearing sleeve and a circular coupling box; the bearing sleeve sleeves the shaft part and is close to the flange part; the coupling box penetrates through the shaft part from right to left, and the edge of a circular hole is fastened on the right end face of the bearing sleeve; a bulge is arranged between the outer edge of the coupling box and the circular hole; the bulge rightwards extends to tightly lean against the diesel engine shell and be fixed; the outer edge of the coupling box tightly leans against the right end face of the main power generator shell and is fixed. A pivot is added on the coupling box, so that the coupling box is connected with the diesel engine shell, and extremely large positive influence on other structures can be caused; the vibration influence is obviously reduced, and the structure is more reliable.

Description

technical field [0001] The invention relates to the technical field of locomotive generators, in particular to a connection structure between a diesel engine and a main generator. Background technique [0002] At present, the diesel engine of a diesel locomotive is connected to the main generator as follows: a junction box is used to connect the main generator and the diesel engine as a whole, and the shafting of the diesel engine and the main generator is connected through an elastic coupling. When the main generator is single-supported, the elastic coupling should bear the supporting role while connecting the shaft system, so the performance requirements of the elastic coupling are too high. While ensuring the performance of the elastic coupling, the transmission efficiency of the shafting is reduced, and the stress, amplitude, and acceleration of various parts of the shafting are correspondingly increased. Contents of the invention [0003] The object of the present in...
