WebThe 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 FVA 2/IV [4]. This test method has proved to be suitable for deter-mining the pitting performance of gear lubricants. WebThe FZG gear test rig is operated at constant speed for a fixed period of time at successively increasing loads until the failure criteria is reached. The test gears are then examined for scuffing damage to the gear tooth flanks both before and after the pre- scribed duration at each load stage.

The standardized testing procedure allows for comparisons with … Webgears, a narrow band of micropitting forms just above, and adjacent to, the dent at the SAP. Shortly after micropitting forms, macropitting initiates from within the micropitting band, …
WebBaseline tests with a non– modified standard– FZG– C– gear were carried out to demonstrate the micropitting properties of the oil. The test gears were standard– FZG– C– gears which had the surface modified by superfinishing to a low Roughness Average (Ra). The pitch line velocity during all testing was set to 8.3 m/s and the ... WebFZG gear wear test (ASTM D 4998) To evaluate the anti-wear properties of lubricants, particularly hydraulic fluids for tractors, test gears on the FZG rig are operated at 100 rpm for 20 hours at 121°C (250°F) and load stage 10.
WebNov 12, 2024 · Experiments at an FZG bearing power loss test rig were conducted to investigate the loss behavior of roller bearings with water-containing gear fluids. Figure 1 a shows the mechanical layout of the test rig, consisting of a speed-controlled electric engine, a loss torque meter, a radial and axial load unit, and a test housing.
WebThey tested FZG PT-C macropitting gears and FZG GF-C micropitting gears, which are the same in all respects except PT-C gears have a tooth surface roughness of R a = 0.3 µm, whereas GF-C gears have a tooth surface roughness of R a = 0.5 µm. PT-C and GF-C gears are peculiar because they have no profile modification, such as tip or root relief. bauhaus wandregalWebThe Gear Research Centre (FZG) is an integral part of the Faculty of Mechanical Engineering at Technische Universität München in Germany.
