Low weight, corrosion resistance, smoothness, minimal maintenance thanks to self-lubrication and last but not least a good price-performance ratio: Plastic gears offer numerous advantages compared to steel models. Norelem has now added numerous versions to its range, which can be used thanks to the high-performance materials used in various industrial areas.
The drive elements can reliably handle power transmission and positioning tasks in mechanical engineering and in automation technology. To ensure spur gears a positive and slip-free transmission of forces with changing direction, for example, for lifting and lowering of machine elements or loads. Spur toothed plastic spur gears with 12 to 150 teeth are available in module 0,5 to 3.
The combination of rack and spur gear converts rotary to linear motion or vice versa. The product range includes plastic models in module 0,5 to 3 with a standard length of 250 mm.
Plastic bevel gears in module 1 to 3,5 are available with translations from 1: 1 to 1: 5 as standard. They are needed above all for the construction of angle gearboxes, which in turn are in demand for applications with high reduction ratios and torques as well as fast movements.
All gearing parts are available in versions made of the standard material polyacetal and the premium material polyketone. While polyacetal guarantees high hardness and a low coefficient of friction, polyketone offers a much longer service life and optimum power transfer. The susceptibility to tooth breakage is significantly reduced. This is ensured by the exceptionally high abrasion resistance and the very good tribological properties of this material.
Under normal conditions both plastics can be used in a temperature range from -40 ° to + 140 ° C.

Hannover Messe success story In a French bakery, the oven for baking bread rolls asked for a new conveyor chain every two years because it was worn out. In order to stop the expensive and time-consuming process, those responsible turned to the manufacturer of drive technology products Tsubaki. After replacing the conveyor chain, two years' lifespan became more than five years.
Hannover Messe Hall 5, Stand D32 / 1 Expert knowledge At the moment, the multi-plate clutch is enjoying increasing demand from designers and developers of industrial drive technology against the background of the Ringspann product offensive, which has been running for two years. In the field of shaft couplings, this has led to the addition of numerous new types of couplings to the portfolio. This addresses the correct selection and design of the non-switchable, torsionally rigid shaft couplings at the Hannover Messe 2020.
Hannover Messe Hall 5, Stand E04 Intelligent machine elements provide important measurement data for transparency in the drive train. This is how they support efficient and predictive machine maintenance. At the Hannover Messe 2020, Mayr Antriebstechnik presents intelligent solutions for brake monitoring as well as new approaches for networked clutches. The drive specialist invites visitors to think along the new paths.
Logimat Hall 1, Stand A08; FMB South Stand C7 Habasit offers high-quality toothed belts from the Habasync series with practical mechanical end connections for quick changes. This means that the operating costs of conveyor lines can be reduced through short assembly and maintenance processes, such as when changing timing belts. Endless belts can alternatively be connected to mobile heating presses directly on site. This significantly reduces downtimes when changing a toothed belt.
Case Study A British car manufacturer had a problem with the maintenance of the conveyor chains that power its lanyards. This is used to transport the assembling car body components. The roller chain had to be replaced too often, otherwise it would have caused production to stop. The problem was solved by converting to a special conveyor chain from Tsubaki. To do this, only the TCO costs had to be put in the foreground instead of the purchase price.
KBK Antriebstechnik has developed the KBGK and KBGK-T articulated couplings that connect shafts and components with extremely little play and even compensate for high radial and angular misalignments. They are made from high-quality materials such as aluminum and steel, are torsionally rigid in the circumferential direction and give in to radial forces and angular deviations.
The ball screw or trapezoidal screw is usually not connected to the drive journal of a motor or gearbox in a rigid manner, but via a flexible coupling. This can compensate for misalignments or misalignments and minimize vibrations and shocks in the drive train. Dr. Tretter now offers compact shaft couplings for this.
SPS Hall 3, Booth 419 Rigid couplings of the "Torqmax step bore" series from Orbit Antriebstechnik enable the play-free connection of shafts with different diameters thanks to their graduated bores. For a low mass moment of inertia, the couplings are made of aluminum, additionally anodized to prevent corrosion, and some are also available in stainless steel.
SPS Hall 4, Booth 278 Mayr Drive Technology presents new versions of the "Roba-brake-checker" module, which can now also be used to monitor small brake sizes. This opens up new possibilities for brake monitoring - especially with spring-applied brakes in servomotors and for applications in robotics and automation.
