Therefore, experimental investigations regarding high cycle fatigue have been carried out in a pulsator test rig on gears of various sizes, materials and residual stress conditions. As a result, depending on the existing residual stress condition, there...

The face load factor K Hβ , which in rating equations represents the load distribution over the common face width in meshing gears, is one of the most important items for a gear strength calculation. In the...

This study investigates the stresses and deflections of a floating ring gear with external splines working in a large planetary wheel motor of a mining truck. Such calculations carried out with conventional engineering approaches described in popular...

Epicyclic gear stages provide high load capacity and compactness to gear drives. There is a wide variety of different combinations of planetary gear arrangements . For simple epicyclic planetary stages when the ring gear is stationary, the...

To date, grinding, according to the German DIN Standard 8580, is “machining with geometrically undefined cutting edges” while other machining processes such as turning and milling are classified as processes with “geometrically defined cutting edges”. New abrasive...

When industry is looking at the best ways to increase efficiency, reduce downtime and increase profitability, gearbox performance and reliability are key factors. In most applications gearbox reliability is critical to the productivity of the overall plant...

Gear root is an important but often neglected element of the gear. The stress concentration point typically lies in the tooth to root transition area and it is this point that determines the life or the fatigue...

Dressable vitrified bond cBN grinding tools combine the advantages of other common tool systems in generating gear grinding. The cBN grains are a highly productive cutting material due to their high specific stock removal rate. Vitrified bonds...

The skiving process is multiple times faster than shaping and more flexible than broaching, due to the continuous chip removal in skiving, but it presents a challenge to machines and tools. While the roll motion between the...
