Optimum Oil Level for Small Gear Boxes
Abstract
The optimum oil level was determined for small splash lubricated right angle gear boxes. The major components of the boxes were forged bevel gears, tapered roller bearings, steel shafts and aluminium housings. The 'Four-Square' method of testing was used for all tests. Normal load and overload conditions along with economic considerations showed that 200 to 300 ml or approximately 30 to 40% of the volume capacity was the optimum level. For normal load conditions within design and thermal limits, the operating oil temperature was independent of oil level for four different brands of oil and three different load levels. For overload conditions, the operating oil temperature was lowest in the range starting at the minimum level for splash lubrication up to 40% of the gear box capacity. The temperature increased for all subsequent levels up to full capacity. (A)
