Abstract: The gear transmission system in aircraft engines often operates under high-speed and heavy-load conditions.
Reliable lubrication is crucial to ensure that the spiral bevel gears do not experience gear scuffing or pitting. In aircraft
accessory gearboxes, spiral bevel gears often rely on oil jet lubrication. However, the oil spray parameters designed
empirically do not consider the lubrication degradation caused by jet breakup due to rotational speed, making it difficult
to meet the design requirements of aircraft gear transmission. A Finite Volume-based thermal-fluid coupling simulation
model of spiral bevel gears has been established to consider the influence of actual conditions such as gear speed, oil
spray velocity, spray angle on lubrication and heat dissipation effects, supporting the high-reliability and high-power
