Apex Dynamics debuts PFII series of gearboxes

Designed with efficiency and simplicity in mind for use in shaft-driven actuators, linear units and machine axes, the PFII Series delivers high torque, low noise and precision. With an extremely compact and efficient design, PFII gearboxes feature an innovative coaxial configuration using a hollow input and output shaft. This means the output shaft is in line with the motor shaft, combining excellent performance with smart design.

PFII gearboxes feature hardened planetary gears, combining high torque and precise operation with low noise and high speed. In addition, the adapter housings are made from lightweight aluminum to reduce weight without compromising performance or reliability, and internal gearing is made from alloy steel to support both high torque and rigidity.  

The PFII comes in three frame sizes, with a wide range of gear ratios from 3:1 to 1000:1. It provides high performance with a rated torque up to 232 Nm and high accuracy, with backlash down to six arc minutes. 

One of the key features of the PFII range is the way in which the output shaft is clamped. A radial clamping ring is used for both input and output shafts, with the clamping ring on the output side equipped with two radial bolts to handle higher torque. This offers significant benefits over traditional systems, providing easy assembly and maintenance, and compact design as well as higher tolerance, robustness and greater suitability for dynamic applications.

The PFII enables shaft-to-shaft power transmission connection between two rotating shafts and versatile mounting specific to the motor. Customized adapters are available for shaft actuators, while Apex Dynamics can also supply couplings where they are required. Apex Dynamics zero backlash precision couplings are designed for shaft-to-shaft connections and come in elastomer and disc variants, with a wide variety of input and output configurations. The company's couplings are machined-to-order, with delivery guaranteed in just 2-3 weeks.

"The PFII series provides high performance and reliability for shaft-driven actuators and machine axes in a light, compact, economical package," said Mike Gulliford, MD of Apex Dynamics UK.

"Designed to drive shafts with power and accuracy, the compact design and aluminium adapter housings provide a space-efficient, lightweight solution, while the patented design reduces the risk of over-determination by ensuring the hollow output shaft does not experience radial or axial loads. Suitable for a wide range of industrial applications, we are delighted to launch this new series in the UK."

Available now, with Apex Dynamics’ five-year warranty, 2-3 week lead time and guaranteed delivery, the patented PFII gearbox range is an accurate and reliable choice for a wide range of industrial applications.
