Gearing Reference Guide TORQUE-ARM II TORQUE-ARM MAXUM Concentric Reducer TIGEAR-2 ENGINEERING/TECHNICAL MAXUM Concentric Reducer DODGE MAXUM Concentric Shaft Reducers can be modified to permit mounting in positions other than the conventional (A-1) floor mounting. Some of these include ceiling (A-3) and wall (A-2 and A-4) and various inclined, vertical and tilted positions. Consult DODGE to determine what modifications are required for your specific application. In order for DODGE to make recommendations on the required modifications, the following information must be provided: FEATURES/BENEFITS PAGE G3-3 Angle Of Incline Specify Input or Output Shaft Up A-3 A-2 Viewed from Output Shaft NOMENCLATURE PAGE G3-6 G3-78 Angle Of Tilt Specify Left or Right Side High When Viewed from Output Shaft • Reducer Size. • Ratio. • Input and/or output speed. • Transmitted Horsepower. • Duty cycle. Continuous or intermittent operation. If intermittent, running time vs. idle time. • Mounting position, such as A-2, A-3 or A-4 with shafts level, or a more complete description of the mounting arrangement including the angle of tilt of the housing, the incline of the shafts and whether the output shaft is higher or lower than the input shaft.

ENGINEERING/TECHNICAL MAXUM Concentric Reducer Vertical And Inclined Application When the reducer is mounted vertically, the upper bearings will not receive adequate lubrication from normal means of splash lubrication. The MAXUM reducer design uses a center web in the housing to support the inside bearings. This center web becomes a splash baffle when the reducer is mounted in a vertical position so other alternatives for lubrication need to be considered. DRAWING A In addition to the Nylos Ring, we provide a means to initially charge and replace the grease reservoir. The seal carrier of the housing is drilled, and a grease fitting is provided to maintain a level of lubricant in this cavity. Lubrication of the upper gearset also needs to be SPECIAL SEAL CARRIER OIL FILL LEVEL FEATURES/BENEFITS PAGE G3-3 GREASE FITTING PLUMBING HARDWARE TO RAISE OIL TO PROPER LEVEL DRAWING B GREASE PATH GREASE RETAINER (NYLOS RING) NOMENCLATURE PAGE G3-6 GREASE RETAINER (NYLOS RING) G3-79 The MAXUM solution to this problem is to use a Nylos Ring - a thin dish or cup mounted between the shaft shoulders and the Timken cone (see Drawing A). The purpose of this cup is to hold a reservoir of grease to lubricate the upper bearings. If the low speed shaft is up, we provide this modification for both the low speed pinion bearing and the countershaft bearing. SHAFT SEAL considered, and this is provided for by increasing the lubricant level to make contact with the upper gearset. We provide this information for each application, by a drawing similar to Drawing B below.
