distributing the lubricant of the Wuma variable gearbox

In vertical variable gearbox, a special problem of lubrication exists.
The vertical gear reducer housing is commonly employed as a lubricant reservoir and the lower shaft bearings which mount the vertical shafts are below the level of lubricant in the housing so that they ice may simply be exposed to the lubricant in the housing. However, the upper shaft bearings for the vertical shafts are above the level of lubricant in the housing and it is, therefore, necessary to provide means for drawing lubricant from the housing, lifting it to the level of upper bearings and then distributing the lubricant to all of the upper bearings.
