The Stealth Gen II helical planetary gearheads incorporate design enhancements to provide superior performance for the most demanding high-performance applications. The Gen II gearboxes have dual angular contact bearings, providing higher radial load capacities while maintaining high input speeds. Design enhancements also include full compliment needle bearings allowing for increased service life and therefore extended warranties. Due to these internal design changes and optimised gearing geometry it means just one fill level for any orientation, resulting in shortened part number designation and simplified ordering.

Universal mounting kits provide a common mounting method which is used across multiple product lines to promote quicker deliveries and easier mounting to any servo motor. Applications that do not require a high level of precision can still be fulfilled using the PE-series gearboxes.

Key Features and Benefits

Increased Radial Load
Four times greater in some frame sizes, this is achieved by the implementation of dual angular contact bearings to support the output carrier and an enhancement of the internal bearing support structure. This entails the gear pilot lengths to be increased by:

• 3mm for the 60mm frame
• 4mm for the 90mm frame
• 3mm for the 115mm frame

Increased Service Life
The new gearbox generation is designed for a lifetime of 20,000 hrs and during this time no lubrication is needed and therefore lifetime increased. This is accomplished by optimising the lubrication paths and gear geometry in the gearbox and implementing a full complement of needle bearings to support the planet gears. This is true except of the right angle gearbox with ‘Input up orientation’.

Universal Mounting kit.
These kits have been designed to be used across the complete Gen II gearbox range and applies to the released PS & RS gearboxes. This enhancement enables simplified ordering which means quicker delivery across the entire gearbox range. The length of the mounting kit may change dependent on the motor being fitted.

The major benefits of these gearboxes then are high torque and low backlash achieved by use of helical planetary gearing. High stiffness made possible by the use of an integral ring gear and rigid sun gear and higher gear wear resistance resulting from a Plasma Nitriding heat treatment.
