Abstract
A speed reducer for a mixing apparatus having a gear train mounted within a housing such that the output shaft is supported by upper and lower bearings mounted within the upper portion and base of the housing, respectively. The lower output shaft bearing preferably is mounted within a recess in the underside of the housing base below a dry well containing the output shaft. The dry well forms a lubricant sump within the housing and preferably is unitary with the housing base. By placing the output shaft bearing below the dry well in the base of the housing, the diameter of the bearing can be increased to bear larger loads without being restricted by the dry well and is better able to transmit bending and radial loads to a relatively massive portion of the housing, and is placed closer to the load, thereby minimizing the amount of unsupported output shaft projecting from the reducer.
