Simulation analysis of spur gear injection lubrication based on different injection angles

In order to study the lubrication distribution characteristics of gearbox gears under the lubrication condition of different injection angles, the gear lubrication experimental platform was set up, and the experimental results of different injection angles were summarized. Through the analysis of the physical quantity of the oil film coverage on the gear surface, the oil film distribution on the bearing surface and the optimal scattered injection angle of the tooth surface are obtained. The results show that the control angle is between 75 °and 105 °. In this way, better coverage and larger HTC can be obtained at the same time, and the comprehensive lubrication effect can be optimized.
