Features

Varitron Planetary Gearbox Inside view

 

- 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 Design 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.

Applications

 

Application of Planetary Gearbox

 

Planetary Gearboxes are used on high precision motion control application that require a high torque, high torsional stiffness and low backlash the specifics of which will vary by application.

 

Planetary gearboxes increase the torque by the stage of reduction ratio, making it possible to run the motor at a higher, more efficient speed.  The inertia reflected back to the motor is reduced for increased stability.  Using a planetary gearbox allow machine builders using a smaller, less expensive motion control package.

 

The application of planetary gearboxes covers the entire range of automation.  It's frequently found in "pick and place" systems, loading and unloading gantry robots, driving rotary and linear actuators, in packaging machineries, positioning tables in medical equipment.
