3 Power Wheel Final Drives INTRODUCTION Auburn Gear is your reliable source for a variety of power transfer products. This catalog features the Model 6 family of Power Wheel Planetary Gear Drives. Other models of Power Wheels are also available; for a complete offering, contact Auburn Gear. We also offer planetary gear kits and spin resistant differentials. We offer you services for design, engineering, prototype support and full testing and production capabilities. Product applications include aerial lift, agricultural, automotive, construction, forestry, industrial and marine. Auburn Gear offers you quality and reliability backed by more than 5 years of experience. Greater Design Flexibility Power Wheel planetary drives allow greater flexibility than conventional power train systems and often eliminate the need for components such as drive shafts, axles and chain drives. The many models and styles offered meet a wide range of mobile and industrial application requirements. Single and double reduction ratios can be furnished. In addition, they can be supplied with a variety of motor mounts and inputs which allow them to be used with most makes of hydraulic motors. High Efficiency and Compact Design Providing 96 to 98% power transfer efficiency, Power Wheel planetary drives are significantly more efficient than many other types of drives, including differential design planetaries. The rugged, compact design of these drives saves space and provides for long service life. All models can be furnished with parking brakes. Auburn Gear has designed integral A2 Series parking brakes in Models 5, 6, 6B, 7, 8, 8B and 9. These units provide a very compact planetary drive/parking brake package which is particularly useful in applications where space is limited. Responsive Performance Power Wheel drives deliver the power you require for smooth operation and precise control. These units are also fully reversible. Reverse power is easily obtained by reversing rotation of the input. For vehicle applications, the positive traction provided by individually powered wheels results in superior maneuverability and improved ground clearance than conventional drive systems. Auburn Gear Power Wheel drives can be an efficient solution for any application where you need to increase torque or reduce speed to achieve usable power. Let Power Wheel planetary drives help you put power in its place.

14 Power Wheel Model 6 Shaft Output Drives Single and Double Reductions with A2 Series Integral Parking Brake PISTON: Improved design for superior life at higher pressures FRICTION DISCS: Heavy Duty Graphitic Paper for wet sump applications. Characteristics: Superior energy capability, high and stable coefficient of friction and smooth engagement. GENERAL A2 SERIES DATA:. Maximum operating pressure is 3, psi (26.4 Bar). Pressure spikes or surges not to exceed 3,5 psi (24.8 Bar). Surge pressure in excess of 3,5 psi (24.8 Bar) caused by spikes in the hydraulic system could shorten brake life and must be avoided. 2. Use only SAE grade 8 mounting bolts and torque to 8-9 lb. ft. (8-22 N-m) for motor mounting. 3. PRECAUTION: Bench testing may cause distortion of components or bolt failure. Mounting bolts must be used for supplemental clamping. 4. Minimum Release Pressure is defined as the hydraulic pressure required to obtain full running clearance. 5. Cubic Inch Displacement is the volume of oil required to release the brake piston. in 3 (6.4cc) for a new brake and 2. in 3 (32.8cc) for a worn brake pack. 6. For vertical shaft output applications, shaft up or shaft down, please contact Auburn Gear to insure proper brake configuration is specified.

32 Model 6 Series B Power Wheel MODEL 6 SERIES B FEATURES LARGE TAPERED ROLLER BEARINGS ALLOW INCREASED AXIAL AND RADIAL LOADING DUCTILE IRON HUBS PROVIDE ADDED STRENGTH FOR RESISTANCE TO IMPACT LOADING DOUBLE HEAT TREAT SPINDLES PROVIDE TOUGHNESS AND INCREASE FATIGUE LIFE BEARING NUT PROVIDES PRELOAD TO OPTIMIZE BEARING LIFE OPTIMIZED GEAR GEOMETRY INCREASES THE CONTACT RATIO, WHICH ENHANCES GEAR LIFE PERFORMANCE FEATURES - MODEL 6 SERIES B VERSUS STANDARD MODEL 6 SIMILARITIES: Torque Rating: Both use the same optimized gear geometry and gear material, therefore they both are rated at 5, lb-in (5,65 Nm) of intermittent output torque. DIFFERENCES: Bearing Retention: Standard Model 6 uses a snap ring which provides end play/clearance. The Model 6 Series B uses a bearing nut which provides preload/no clearance. Therefore, the Model 6 Series B will provide reduced deflections in the gear box, which will enhance the life of a unit in certain applications. Hub Material: The strength properties of Model 6 Series B hub are slightly greater than the standard Model 6. This provides a greater resistance to impact loads, which are common in certain applications. Spindle Material and Heat Treatment: Again, the Model 6 Series B spindle properties differ and are enhanced over the Model 6. These differences allow for increased fatigue life under high impact and side loading. Bearing Capacity: The Model 6 Series B has greater radial and axial bearing capacity which may be required in certain applications.
