Automobile Assembly Lines and Gear Lubrication

The conveying  machinery  of  automobile  assembly  plants is  driven by gear  reduction  units  which  are  powered  by  electric  motors. Floor level conveyors may have variable speed transmission units and spur gear trains in order to obtain the very slow rate of travel desired. The  speed  reducers first  mentioned  are enclosed and  lubricated  with  grades of oil  conforming  to AGMA  recommendations for the average  speed   of  the gear  train. Spur gears driving the floor conveyors may be too large to house economically and will be lubricated by intermittent spray of SAE 90 gear oil. Gear lubrication in additional facilities of automobile factories or of auxiliary plants supplying parts to assembly lines will be treated elsewhere.
