Methods of Application of Gear oils to Heavy Duty Gears

Older equipment employing heavy duty gears may make use of bath systems   for application. Many  plants  have  converted  such  systems  to  circulating  application such as  is used  on most  modern  machinery. By  this  means, oil sprays  can  be  directed  to  the line  of  meshing  of the  gear  teeth and  if  necessary the  oil can be supplied  to  other  machine  components, such  as  bearings. By  this  means, when  accompanied with  proper auxiliary equipment, such as coolers, filters, settling tanks etc., the life of the oil is prolonged and contaminants removed.

Carbonated Beverages and Gears

In preparing   beverages, gears are often used on meters to synchronize delivery of syrup and water to carbo coolers. Also on automatic   bottle cleaners, gears are used to rotate brushes both on the inside and outside of the bottle. These latter gears are often flooded with the detergent   solution used in washing and other lubrication is not permitted.

Conveyors, in such  establishments, when  driven  by  reduction gears,  can be  serviced  by  an  oil  of about  500  viscosity SUS at 100 degree F, if enclosed, or a residual  type  of about  2000 SUS at 210 degree F, if of the open  type.
