J et al. 25 showed that the effect of friction on bending strength of spiral bevel gears was greater than that of contact strength, which was verified by theoretical calculation and finite element analysis.

Compared with the conventional gear, the asymmetric gear has better root bending stress and tooth contact stress. Taking a pair of asymmetric involute spur gears as the research object, a model of asymmetric gear considering the influence of friction and shear stress on root bending stress is established. Take the upper boundary point of single tooth meshing area as example, the formula for calculating root bending stress of asymmetric gear is deduced under friction, get the rule of root bending stress without neglecting the friction force and the shear stress by MATLAB. At the same time, we design the plane finite element model of conventional gear (20°/20°) and asymmetric gear (20°/35°) by using APDL. The upper and lower boundary points of the double tooth meshing area, the upper and lower boundary points of the single tooth meshing area, the meshing node are systematically studied, get the change rules of root bending stress in the meshing process under the condition that the friction force cannot be ignored.

“…Handschuh et al 11 explored and researched the effect of the oil-jet location and velocity (injection pressure) on the bulk temperature field of spiral bevel gears with numerous experiments that found the pinion base temperature should be a primary and prior consideration and the out-of-mesh jet nozzle position could be an optimal choice. Zhou et al 12,13 reached conclusions that the friction exerted a considerable influence on the bending and contact strength of a spiral bevel gear pair, especially under extreme operating conditions. The results have been verified by methods of theoretical and finite element method analysis implying an urgent need for better lubrication to lessen frictional resistance.…”

In aeroengine industry, the oil jet layout significantly influences lubrication of high-speed and heavy-load transmission gears, as there is only extremely limited meshing clearance for the oil stream jetting into and an inevitable blocking effect of rotating gears. A novel mathematical model for calculating the exact impingement depth of the lubrication oil jet on the spiral bevel gear surface has been established, and it contains comprehensive and detailed design parameters for the jet nozzle layout and meshing gears. Furthermore, under different jet layout parameters conditions, computational fluid dynamic numerical simulations for oil jet lubrication of an aeronautical spiral bevel gear pair were conducted and, then, the simulation results are compared with the impingement depths based on the mathematical model. The simulation results reveal that the oil volume fraction and oil pressure on the meshing area increase with the impingement depth, validating the effectiveness and reliability of the method using the impingement depth mathematical model for evaluating oil jet lubrication. Optimized oil jet layout parameters including the jet nozzle position, jet elevation angle, and jet azimuth angle have been determined and recommended, and they provide valuable theoretical design methods and technical guidance for oil jet lubrication optimization for various practical high-speed and heavy-load spiral bevel gears.

“…Through comparison between Spiral bevel gears and straight bevel gears (zerol), have supplementary overlapping tooth action, that generates a smoother gear mesh. This smooth power transmission for the gear teeth lessens vibration and noise that raise exponentially at upper velocities [5,6]. Consequently, the spiral bevel gear ability for variation in the mechanical load direction, coupled with their capability in vibration and noise decrease, create them a major applicant for usage in industry, advanced machine tools, vehicles and airplanes.…”

Spiral bevel gear is typically adopted in high-speed mechanism components that transmit power and rotational motions amid dual intersecting shafts have (right angle axes). Therefore, because of the change in counterbalance, they may have slightly varies dynamic behaviour and gear mesh characteristics. Furthermore, the friction and lubrication effects may moreover play a significant character in its dynamic performances. The effect of variation loads with different materials on the spiral bevel gears have been analyzed and studied in this paper.
