Problems solved by technology

Special nonlinear dynamic behaviors such as bifurcation, chaos, and amplitude mutation caused by resonance will cause the meshing force between gears to be in a state of irregular motion for a long time, or even change abruptly, resulting in vibration and noise in the entire gear transmission system. Reduced service life of the gear drive system

Abstract

The invention discloses an optimization design method for a heavy-load and eccentric-load gear transmission system based on motion stability. The method includes: extracting various internal and external incentive factors affecting the stability and accuracy of the gear transmission, and focusing on introducing due to The influence of the time-varying center distance on the meshing line caused by the deformation of the transmission shaft and the supporting element caused by the heavy load and the gear swing effect caused by the eccentric load are established. Solve the problem, and extract the parameter interval of the stable motion of the system with the help of nonlinear dynamics theory, so that the system can avoid complex nonlinear dynamics behavior, and achieve the purpose of guiding gear processing design and parameter optimization.

Description

technical field [0001] The invention relates to an optimal design method for a heavy-load and eccentric-load gear transmission system based on motion stability. The influence of the time-varying center distance on the meshing line caused by the deformation of the transmission shaft and the supporting element caused by the load and the gear swing effect caused by the eccentric load are established. To solve the problem, judge the motion stability of the system with the help of nonlinear dynamics theory, extract the parameter interval of the stable motion of the system, and avoid complex dynamic response, so as to achieve the purpose of guiding gear processing design and parameter optimization. Background technique [0002] The traditional design process of gear transmission system is mostly designed for the strength of transmission components such as gears and transmission shafts, including gear material selection, force analysis, check calculation of gear fatigue strength, a...
