The compactness of the NTP is an important feature for manufacturers who optimize their machines for the smallest possible footprint. The gearbox - easily recognizable by its blue housing with all-round design element - offers a particularly high torque and power density thanks to its space-saving length. The new NTP has two role models in the Wittenstein alpha portfolio: firstly, the economical NTP gearbox for applications with standard requirements for features such as positioning accuracy. The second is the TP+ low-play planetary gearbox for maximum performance requirements, which is at home in the technological high-end segment.

Technically improved gearing components

Another milestone in the development of the NTP flange gearbox is the completely revised gearing components. The technical improvements primarily relate to their optimized micro-geometry, as a result of which the NTP achieves improved synchronization properties compared to the previous alpha Value line and the market standard. At the same time, the high-quality gearing components have reduced running noise and thus the impact of acoustic emissions in the operating environment.

With the NTP, which is available in four sizes between 015 and 045, maximum torques from 56 to 800 Newton meters and ratios from 4 to 100, the manufacturer is facing an agile competitive environment in all relevant sales markets. In comparison with other gearboxes and brands in this market segment, it is said to be convincing because the combination of several features often sets a new best-in-class benchmark. Sometimes the NTP is ahead due to its low backlash in combination with the higher torque density; sometimes it scores with its superior tilting moments and low running noise; sometimes it is preferred by machine builders due to its torsional rigidity in combination with the increased absorption of external forces. Finally, it is now easier for machine builders to use Wittenstein gearboxes in axes with a wide range of requirements - precisely differentiated in terms of price and performance and optionally configurable with the Wittenstein Cymex design tool. The innovation sectors of handling, automation, packaging technology and machine tools are the most important areas of application for the NTP.
