WVRB – Servo Gear Box

WPF – Servo Gear Box

Planetary boom and integrated output shaft.
Servo Gearhead with full needle design.
Carburised and quenched Gear Reducer.
Zero Backlash Power transmission.

Planetary boom and output shaft are intergrated structure designed to ensure maximum torsional rigidity.
Planetary wheel with full needle design, increase the contact area to improve the rigidity and output torque.
The gears are carburized and quenched to the HRC62 with low carbon steel surface for optimum wear and impact toughness.
Gears refer to foreign imported software-assisted design to obtain the best tooth shape to reduce noise.
The input terminal is connected to the motor shaft in a double-tight manner to obtain the maximum clamping force and zero backlash power transmission.
