The invention relates to a high-linear-speed gear optimal lubrication nozzle orientation determination method, and belongs to the technical field of gear transmission lubrication. A gear engagement finite element model is established, and high-linear-speed single-phase flow gas field simulation analysis is performed on the gear engagement finite element model; the method comprises the following steps: establishing points to be selected of a plurality of spray points in an engaging-in side area or an engaging-out side area of an engaging gear, determining the optimal lubricating nozzle position through the speed streamline of each point to be selected, finally determining the optimal nozzle position coordinate, and spraying towards a pinion on the central plane of the two gears in a range of a distance L between the central plane of the two gears and a tangent point of a reference circle of the two gears being 30-40mm, and transient flow field simulation analysis verification is carried out on the determined optimal lubrication nozzle orientation. According to the method, the optimal nozzle arrangement direction is screened and determined through fluid transient finite element simulation analysis, and finally, through oil injection process simulation analysis of the nozzles, it is verified that the determined nozzle arrangement direction can make the oil volume fraction of meshing tooth surfaces at the meshing moment excellent; and good lubrication of the high-speed meshing gear in the service process can be ensured.
Description
technical field [0001] The invention relates to the technical field of gear transmission lubrication, in particular to a method for determining the orientation of an optimal lubrication nozzle for a high linear velocity gear. Background technique [0002] Gear transmission is gradually developing in the direction of high linear speed and high load. Compared with traditional low linear speed gears, the relative sliding between the meshing tooth surfaces of high linear speed gears increases during service. If the lubrication is insufficient, the meshing tooth surfaces Friction generates a large amount of heat, which causes the temperature of the meshing tooth surface to rise sharply, and the meshing tooth surface is prone to wear and gluing damage, which affects the gear transmission performance. [0003] In aviation gear transmission, oil injection lubrication is often used to lubricate and cool the gears. At present, the design of the orientation parameters of the gear lubri...
