Gear lubricants helical gears

Gearing is single helical or spur gear lubrication usually is an automatic spray type. Single drives are used up to 150 kW. Kilns requiring more than 150 kW may be equipped with dual drives, i.e., two driving... 

For highly loaded spur, helical, worm and bevel gears, lubricants containing tribological additives such as sulphurized and phosphorus-containing additives are used. These provide excellent anti-wear and extreme pressure protection over a wide range of conditions.

When selecting a lubricant, both the temperature at the contact area and the ambient temperature at important factors to be considered. Measuring the peak contact temperature is very difficult. The maximum rise in temperature of the oil leaving the gears and the maximum oil temperature are specified for various types of gears. For spur, bevel, helical and spiral level gears, the temperature rise should not normally exceed 30°C (86°F) with a maximum oil temperature of70°C (158°F).

Common Materials. Gears may be made of a wide range of materials that may be ferrons, nonferrous, and nonmetallic. For indnstrial applications of spnr, helical, and bevel gears, steel is most commonly used, with iron and other metals occasionally nsed. Wormgear pairs generally are made up of bronze or iron for the wormwheel and steel for the worm. Use of plastics is generally limited to light applications, particnlarly those in which minimal lubrication is available.
