Quality Gear box by Varitron from TAIWAN
Varitron RAM-D Series Hollow Shaft Right Angle Spiral Bevel Planetary Gearbox
- 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.
- 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.
- Single-piece Gearbox & 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 corrosionresistant 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.
- 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.
