AI Technical Summary
The existing experimental setup cannot flexibly adjust the spatial staggered installation relationship of non-orthogonal gears, resulting in insufficient accuracy and poor reliability of experimental data, and lack of effective online monitoring methods.
A high-speed oil injection lubrication experimental device for non-orthogonal gears was designed, which includes a multi-dimensional adjustment platform, a magnetic powder brake and a high-precision torque meter. It can accurately adjust the center distance, offset distance and shaft intersection angle of the gear pair, and is equipped with an infrared thermometer and a fiber optic oil film sensor for real-time monitoring.
This study achieved precise simulation of experimental conditions for non-orthogonal gears, improving data accuracy and reliability, and ensuring the accuracy and reliability of experimental results.
