The gears are rotated by a variable speed electric motor. The rig is operated at rpm through up to 12 progressive load stages at 15 minute intervals. Gear teeth are inspected after each load stage for scuffing.
In addition to a visual evaluation of gear tooth condition, gear weight loss is measured. The rig is operated at rpm under constant load for 20 hours. A visual tooth surface rating and gear weight loss are measured. Tests are run up to hours under constant load, temperature, and speed. Inspections are conducted at predetermined intervals for pitting damage on the gear tooth faces.
This test requires A10 gears half the tooth width of the A gears , and is run at rpm in reverse mode. Gear type, fluid temperature, gear load, and rotation speed can all be controlled to customer defined settings. Intertek Global Website. A test gear pair with a special tooth geometry runs in the testing lubricating oil according to the immersion lubrication method.
The temperature and speed are specified. The load on the tooth flanks is gradually loaded via a lever loaded with weights, which clamps one of the shafts against the other. From load stage 4, the pinion tooth flanks are inspected for any damage after each power stage. Report bugs here. Please share your general feedback.
