WebThree sets of FZG gears were tested; all gears were the sliding-speed-balanced tooth configuration “FZG”, type C-GF. Each set was comprised of a gear and a pinion. Geometric data of the gears, tooth quality, heat treatment and … WebSep 13, 2024 · The mean gear coefficient of friction μmz represents the “tribological” share of the load-dependent gear power loss. In terms of spur gears, there are several empirical approaches and calculation models available, e.g. Stribeck [ 42 ], Michaelis [ 26 ], Fernandes et al. [ 9] or Jurkschat et al. [ 16 ].

WebSep 13, 2024 · In this process, standardised FZG type A gears are subjected to specific load stages and checked at specific time intervals or cycles. The tooth flank contact pattern is analysed, and the damage progress is documented. Ideally, the gears are weighed after each load stage. WebApr 18, 2016 · S l min > 2 : low risk of micropitting. Table 2: Evaluation of earlier micropitting tests performed using the AGMA tribology gears. The specific lubricant film thickness, l GF,min, is calculated from the ratio, h min / R a, where h min is the film thickness calculated with Equation 1 and R a is the arithmetic mean roughness of the gear tooth surfaces. … how to repair gear new world
