“…θ p1 and θ g1 represent the position parameters of the pinion and the face gear at the initial time (t 0 = 0), and their relationship can be deduced by the rotation angle relationship between the face gear and the gear shaper cutter during the machining process. The rotation angles ϕ g and ϕ s of the face gear and the gear shaper cutter satisfy the transmission ratio [26]:…”

The oil jet lubrication performance of a high-speed and heavy-load gear drive is significantly influenced and determined by the oil jet nozzle layout, as there is extremely limited meshing clearance for the impinging oil stream and an inevitable blocking effect by the rotating gears. A novel mathematical model for calculating the impingement depth of lubrication oil jetting on an orthogonal face gear surface has been developed based on meshing face gear theory and the oil jet lubrication process, and this model contains comprehensive design parameters for the jet nozzle layout and face gear pair. Computational fluid dynamic (CFD) numerical simulations for the oil jet lubrication of an orthogonal face gear pair under different nozzle layout parameters show that a greater mathematically calculated jet impingement depth results in a greater oil volume fraction and oil pressure distribution. The influences of the jet nozzle layout parameters on the lubrication performance have been analyzed and optimized. The relationship between the measured tooth surface temperature from the experiments and the corresponding calculated impingement depth shows that a lower temperature appears in a situation with a greater impingement depth. Good agreement between the mathematical model with the numerical simulation and the experiment validates the effectiveness and accuracy of the method for evaluating the face gear oil jet lubrication performance when using the impingement depth mathematical model.

“…Strength analysis is an integral part of any mechanical design, especially for gear (Patil et al, 2014;Huang et al, 2013;Pedrero et al, 2007;Chang et al, 2000;Wei et al, 2011). Similarly, strength analysis for line gear wheel is also essential, especially for the line gear pair applied in the traditional machine, because the existing structure of the line gear pair is easy to be deformed in application of large transmission torque of traditional machine (Chen, 2014;Chen et al, 2009Chen et al, , 2013a.…”

Abstract. In this paper, the design methodology for a skew line gear pair oriented to additive manufacturing technology, with an one-tooth driving line gear and its coupled driven line gear, used for the conventional powered transmission, is researched based on strength analysis. First, the expressions of meshing forces on the line tooth of line gears are deduced; the deformations and stresses of existing structures of a line gear pair are analyzed by using ANSYS Workbench. Then, the reliable structure and the parameters standardization formulae of a line gear pair are deduced by stiffness and strength analyses. Finally, a design case shows that the proposed design methods provide a convenient and reasonable design tool for designing a skew line gear pair in conventional powered transmission field.

In order to solve the time-varying bending bearing capacity of orthogonal curve-face gear, we proposed the calculation and test method of bending stress of gear tooth root. Using the spatial engagement theory and gear carrying capacity theory, the parametric equations of pitch curve and pressure angle on the pitch curve of orthogonal curve-face gear were derived, and the algorithm of equivalent tooth form factor and equivalent stress correction factor was obtained. Force condition in the meshing process of orthogonal curve-face gear was analyzed. The variation of principal curvature and force of orthogonal curve-face gear was achieved. Using the simplification algorithm of regarding the orthogonal curve-face gear pair as equivalent non-circular gear rack, the calculation method of bending stress of orthogonal curve-face gear was acquired, and the impact of basic structure parameter of gear pair on bending stress was analyzed. Using five-axis CNC machining to process the entity. Experimental of orthogonal curve-face gear using strain gauges was carried out to justify the correction of the theory. Comparing the theoretical calculation and experimental results, the variation laws was similar, and then the calculation method of bending strength of orthogonal curve-face gear was verified.
