This paper presents a numerical temperature simulation for worm gears that considers transient multidimensional heat transfer and local frictional loading due to the contact.

FZG Pitting - Type C Gears Evaluates gear pitting resistance of fluids using C profile gears. Tests are run up to 300 hours under constant load, temperature, and speed.

In the FZG standard scuffing load test, a defined load is applied to a pair of spur wheels, which is increased after a certain run time. After each load stage, the gear wheels are inspected …

A new type of gear pair, the curve-face gear pair, composed of a curve-face gear and a non-circular gear with mutual engagement, was proposed to achieve variable ratio transmission of...

The FZG standard back-to-back test rig with center distance a = 91.5 mm [1] is operated using specified FZG-C-PT test gears with surface roughness values of 0.15 µm ≤ Ra ≤ 0.40 µm in …

In continuous work over many years the standard FZG back-to-back gear test rig was developed and improved for different types of gear failure simulation. The standard FZG oil test A/8,3/90 …

In this work, the churning phenomena related to grease lubrication are investigated on a back-to-back test rig equipped with two gearboxes exploiting Computational Fluid Dynamics (CFD). The...

The FZG test procedures described in ISO 14635-1, ISO 14635-2 and ISO 14635-3 can be regarded as tools for the determination of relative scuffing performance of lubricants. …

Jan 8, 2025 · Results show that the developed FZG-C HS test method using C-PT gears can distinguish among the aviation lubricating oils with different scuffing load capacities as the …

The FZG Gear Test evaluates anti-wear characteristics and load carrying capacities of lubricants. The FZG gear test rig simulates a misaligned gear set operating in a bath of lubricant …
