“…Equations (35) and (36) corresponded to the principle of surface meshing 1–5 and to the principle of space curve meshing, 16–21 respectively. The vectors, which could be expressed by ϕ1 and T in equations (35) to (37), were changed into the same coordinate systems before vector calculation.…”

“…With the development of principle of space curve meshing, which was different from the traditional principle of surface meshing, line gears 16–21 were invented for the transmission between parallel shafts, arbitrary angle intersecting shafts, and arbitrary angle skew shafts. Figure 1 shows a type of primitive ling gears used for the transmission between an arbitrary angle intersecting shafts.…”

Design of pure rolling line gear mechanisms for an arbitrary angle intersecting shafts was presented in this article. Based on the active design method of meshing line function for orthogonal shafts, three meshing types of conjugated tooth surfaces for an arbitrary angle intersecting shafts were discussed, including the parametric equations of different generatrix circles, the mathematical models of tooth surfaces, and central curves to be constructed, respectively. The validity of the active designed meshing line function was verified according to meshing equations, and the theoretical sliding rations were analyzed to prove pure rolling meshing. Then basic design parameters of pure rolling line gear mechanisms for the geometry design were determined, and the main structural parameters were obtained therefrom. Lastly, three groups of numerical examples were proposed according to mathematical models. Resin samples of line gears were processed by rapid prototyping technology and the kinematic performance of the pure rolling line gear mechanisms were validated. This paper laid the foundation of geometry and parameter design for pure rolling line gear mechanisms for an arbitrary angle intersecting shafts.

“…3 In the area of tribology of LG, only the Hertzian contact model and modification of tooth profile of the LGs with intersecting axes have been studied. 4 Engineering practice shows that lubrication is very important for gear drive. Generally, the influence of gear parameters on the lubrication performance is obtained by studying the influence of gear parameters on its equivalent Hertz contact model.…”

Based on the elastohydrodynamic lubrication (EHL) theory, design methodologies are proposed aiming to improve the EHL state of the vertical skewed line gear (VSLG) in this article. First of all, the parametric equations of the driving and driven VSLG surfaces are established and then converted into equivalent Hertz contact model. Then, the influences of the design parameters of the VSLG on the ellipticity are analyzed by its equivalent Hertz contact model. Finally, the parameter design method for improving the EHL state of VSLG is deduced. The results of optical elastohydrodynamic experiment and simulation experiment indicate that the parameter design method is effective for the formation of EHL film without changing the kinematic characteristics of VSLG. In short, this paper provides reliable and convenient parameter design methods for VSLG in consideration of EHL.
