Abstract

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 the angular deviation of the input shaft of the main speed reducer and the output shaft of the high-speed gearbox of the test bed to a reasonable range by calculating the angular deviation of the input shaft of the main speed reducer and the output shaft of the high-speed gearbox of the test bed.

Description

technical field [0001] The invention relates to a high-speed shaft centering calculation method, which is used for fast centering of an input shaft of a final reducer and a connecting shaft of a high-speed gearbox. Background technique [0002] At present, many aviation products need to do a series of tests before delivery or after repairs to ensure the use requirements of the products. For the main reducer of the aviation transmission system, according to the requirements of product assembly, before the test, the angular deviation between the input shaft of the main reducer and the output shaft of the high-speed gearbox of the test bench should be less than 4′. The tools and methods used for alignment The requirements are relatively high; among the currently published patents, such as patent CN109668530A, a method for detecting the centering of a shaft and a shaft hole and a centering detection device are proposed. The method for detecting the centering of a shaft and a sh...
