K Series – Right Angle Helical/Bevel ServoFit Modular System

1 STOBER Drives Inc. ServoFit 2011 web site for "K" Series Right Angle helical /BevelServoFit Modular SystemRight Angle Helical/Bevel gear drives offer higher input-to-output efficiencies than conventional worm gear drives or Right Angle planetary gearheads makingthem the optimal drive for truly demanding continuous Specifications: Input RPM up to 4,500 RPM Nominal output torque 109 to 106,000 in. lbs. (12-11,900Nm) Reducer ratios from 4:1 to 381:1 5 year limited warranty (2 years on bearings, seals, etc.) Ambient temperature 0 C to +40 C (104 F) [Unit temperature < 80 C Max.] Noise level as low as 53 dB(A) Maintenance free Can be back drivenHigh quality helical gearing is case hardened to 58-62 Rockwell finished for low noise and long service life. When the backlash is set by our manufacturingand assemble methods it remains consistent throughout the life of the reducer without further needfor backlash is 12 arc minutes.

6 In order to provide the proper lubrication quantity the mountingposition must be specified at the time the unit is ordered. Our web site: list the oil quantityfor each size and mounting Mounting SpecificationsSTOBER ServoFit Gearheads will fit the motor of your choice by assembling the correct motor mounting plate between the motor and thegearhead. When ordering a gearhead, specify the motor manufacturer and part number, provide the motor drawing with dimensions, orspecify the motor mounting dimensions. The motor plate thickness (L9) dimension will be determined by the motor shaft length. The minimummotor plate thickness is shown below. For a precise dimension on a specific motor, contact STOBER Technical following dimensions are required to provide the correct motor mounting Shaft Diameter (If an adapter bushing is required it will be supplied with the motor plate.)

ServoFit 2011 LoadPulling forces or overhung load of pulleys, sheaves, sprockets, etc. on the reducer output shaft must not exceed the allowable limits shown in theabove calculations. The overhung load shown is measured at the center of the shaft following formula can be used to determine actual overhung load for a given ,100 x kW x KOHL =D x nwhereOHL = Newtons (N)kW = Transmitted KilowattD = Pitch Diameter (meters) of Sprocket, Gear,Sheave, Pulley, = Maximum Shaft RPMK = Single Chain Timing Belt Spur, helical Gear V-Belt Flat Belt DriveNo overhung load is encountered when an reducer is flange mounted and/or coupling connected to another unit.
