The PWT Defawes gears are used throughout the world in the most demanding of applications, because our products meet extremely high quality requirements.
PWT Defawes is a specialist in the engineering of new gearboxes. We have been doing this for decades and have now engineered, produced and delivered over ten thousand gearboxes. From start to finish, including the (detailed) drawings, the parts lists and the instruction manuals.
Our gearboxes provide years of reliable service. And when they need an overhaul? You can also rely on us. Just as you can for the repair and modification of existing gearboxes (regardless of the manufacturer).
We have been producing conical gearsets since 1950. For this, we use machinery from all the renowned manufacturers. For example, we manufacture spiral toothing according to systems such as Klingelnberg Palloїd, Klingelnberg Zyklo-Palloїd, Kurvex, Oerlikon and Gleason. Of course, we not only manufacture spiral toothing, but also conical gears with straight or helical toothing.
Since 1995 we, as PWT Group, have been using our own software as PWT Group for the production of high-quality conical gearsets based on generated NC codes in combination with the use of highly-advanced 5-axis machining stations. It is a worldwide pioneering role that we gladly accept. How is the software package that we developed ourselves different from the rest? The data can be input directly in the controls of the machining stations thanks to the 100% mathematical description of various tooth shapes produced by our engineers.
This special, patented S-toothing, which has been developed by PWT Defawes, eliminates all axial forces and is also stronger than all other models available in the market. The result is more compact installation dimensions for the same performance and the possibility to fit much smaller bearings.
We have a team of trained and experienced engineers with a high level of scientific knowledge and working experience. Every day, they combine their professional knowledge with their years of experience. During their work, they use modern 3D-CAD/CAM software (EdgeCam and SIEMENS NX). Gear calculations are supported by software from KISSOFT, ZAR and Niemann.
