      Varitron Gear box Speed Reducer Motor bonfiglioli 305 planetary gearbox



    Product Description


    Main Features


    -High Precision Gear 
    The planetary gear and sun gear are manufactured from high quality Ni-Cr-Mo alloy steel. Precision machined and carburized, then for precision tooth grinding or skiving assures gears high precision.


    -Single-piece Gear box & Advanced Surface Treatment
    The gearbox and internal gear ring are single price design and constructed, which is manufactured from Cr-Mo alloy steel, and tempered for high torque output. Gearbox surface is anti-corrosive treated for upgrading environmental resistant and corrosion-resistant capability.


    -Integrated Planetary Arm Bracket
    The planetary arm bracket and the output shaft are single piece design constructed to increase torsional rigidity and accuracy. The entire structure is one-time machined for controlling accuracy in the specified tolerance.


    -Modular Deisgn of Motor Connection Plate
    The special modular design of motor connection plate is suitable for any brand and any type of servomotor. Manufactured from aluminum alloy, its surface is anodized treated for upgrading environmental-resistant and corrosion-resistant capability.


    -Modular Input Shaft
    Modular input shaft design and motor shaft are coupled through a dynamic balanced collar clamping mechanism to ensure connection concentricity and zero slip power transmission at high speed.
