Abstract

The invention belongs to the technical field of transmission control, and provides a system deformation calculation method of a transmission gearbox. The system deformation calculation method aims to obtain deformation of shaft systems under the action of a load and improve calculation efficiency. The shaft systems are taken as a basic calculation object, and system deformation is calculated on the basis of shaft system calculation and by means of the meshing relation between the shaft systems and the coupling relation between a shell and the shaft systems. According to the calculation method, system rigidity influences gear dislocation amount, the shaft systems are taken as a calculation unit, calculation efficiency is improved on the basis that calculation precision is guaranteed, the dislocation amount of gears and bearings is obtained, and design bases are provided for fine design of the shaft systems and the gearbox.

Description

technical field [0001] The invention belongs to the technical field of transmission control, and in particular relates to a system deformation calculation method of a gear transmission box. Background technique [0002] Gear transmission is a mechanical transmission that uses the teeth of two gears to mesh with each other to transmit power and motion. It has the characteristics of compact structure, high efficiency, and long life. Among all mechanical transmissions, gear transmission is the most widely used, and can be used to transmit motion and power between two axes that are relatively close to each other. It is used in industries such as machine tools, aero engines, agricultural machinery, construction machinery, automobiles, and military vehicles. Gear transmission is used as a form of power and motion transmission. [0003] With the continuous improvement of the lightweight requirements and power density of the transmission system, the refined design of the product is...
