Centering adjustment method for equipment output shaft and product input shaft

The invention relates to a centering adjustment method for an equipment output shaft and a product input shaft. The centering adjustment method is used for rapid centering adjustment of a main speed reducer input shaft and a high-speed gearbox connecting shaft. An adopted centering tool comprises a first dial indicator and a second dial indicator. During installation, the gauge stand fixing end of the first dial gauge is fixed on the output shaft of the high-speed gearbox, the gauge head of the first dial gauge is in contact with the end face of the diaphragm disc shaft, the second dial gauge is installed on the diaphragm disc-gear coupling through a support, and the gauge head of the second dial gauge is in contact with the sealing installation face of the main reduction input shaft. Wherein the gauge head of the second dial indicator and the gauge head of the first dial indicator are located on the same plane and are perpendicular to each other. And theoretical basis and guidance are provided for adjusting
