Continuous splash lubrication including troughs and feeds and drains to bearings is used on most ratios and speeds. Forced lubrication utilizing oil pumps, filters, heat exchangers, sight gauges and alarm systems is available. Lubrication systems are designed for floor mounting. Other mounting positions are permissible with the concurrence of our Engineering Department.
Based on 100% load and 100% speed the approximate efficiency of parallel shaft units is 98% for double reduction, 97.5% for triple reduction, and 96.5% for quadruple reduction. For right angle units approximate efficiencies are 97.5% for double reduction, 97% for triple reduction, and 96% for quadruple reduction. Actual operating efficiencies may deviate slightly.
GEAR AND PINIONS
Helical gear teeth are cut on high quality, alloy steel material and carburized, hardened and precision ground. The resulting gears and pinions provide high durability ratings with decreased stress and dynamic loads resulting in longer life.
Output shafts are made of heattreated, maximum strength alloy steel, through hardened prior to turning and grinding. Close toleranced bearing shoulders facilitate the mounting of bearings. Highly polished surfaces are provided for oil seals to assure their long life. Large diameters are specified throughout for maximum strength and overhung load capacity.
Husky roller bearings provide maximum longevity. Output shafts have high capacity roller bearings for heavy overhung and thrust loads.
Dual lip type oil seals are standard. Grease purged and labyrinth seals are available options.
