Sliding velocity in profile‐corrected gears

Sliding velocity in profile‐corrected gears

The effects of sliding velocity in a spur gear for a tooth sum of 100 (altered by ±4%) with constant centre distance have been studied. The product of contact stress and sliding velocity (σ Vs) factor is calculated for varied profile shift. The effect of Hertzian compression, bending and shear defle...

Zusammenfassung:The effects of sliding velocity in a spur gear for a tooth sum of 100 (altered by ±4%) with constant centre distance have been studied. The product of contact stress and sliding velocity (σ Vs) factor is calculated for varied profile shift. The effect of Hertzian compression, bending and shear deflection on sliding velocity at points along length of the path of contact has been computed. The scanning electron micrographs at pitch point C show that negative alteration in tooth‐sum gears is better compared with standard and positive alterations in tooth sum.
