01/2020: EVOGEAR – The new servo angular gearbox from Nidec Graessner

Precision meets efficiency
The new servo angular gearbox EvoGear offers outstanding versatility and an optimized design.

EvoGear beautifully combines all the benefits of a powerful gearbox and is geared towards anyone that values a wide variety of ratios, stylish and easy-to-clean design.

More...

As the name suggests the EvoGear gearbox is an advancement - but it’s a mini revolution too, as all of the findings, design aspirations and requirements that we’ve had over the last few years have been invested in a cost-effective, multifunctional product.

That’s why the components were reduced in size, the construction was improved, and more ratios were implemented, as well as additional output variants. The new planetary output level also offers two-stage ratios up to i=100:1 with high torsional rigidity, while the Washdown housing provides enormous benefits in terms of hygiene.

EvoGear is an exceptionally dynamic drive solution that guarantees the highest performance with low dimensions and a low weight due to its compact, stable construction.

The gearboxes are virtually maintenance-free under normal operating conditions due to lifetime lubrication (> 30,000 h S5 load spectrum as a design basis). Its high efficiency factor up to 96 percent also saves energy.

The following frame sizes are available: EG055, EG075, EG090, EG115 which contain the following output variants: L (full shaft), LSV (hollow shaft) with the following ratios: i= 3:1, i=4:1, i=5:1, i=6:1, i=8:1, i=10:1, i=12:1, i=15:1 and PL (planetary output level) with the following ratios: i= 16:1, i=20:1, i=25:1, i=28:1, i=35:1, i=40:1, i=50:1, i=70:1, i=100:1 .

The patented revolution from MS-Graessner
A space pioneer with both feet firmly on the ground. This aptly describes TorusGear, the totally new development in gearboxes from MS-Graessner. Because this revolutionary planar spiral gearbox feels completely at home on difficult terrain.

More...

"Life on Mars" - an illusion? Since 22 November 2016, TorusGear has been helping to take a closer lock there. The gearbox is steering the Mars camera CaSSIS for the first high-resolution images of the Red Planet, with a spectacular view of the surface. TorusGear ensures the high-precision rotation of the reflecting telescope. This unique planar spiral gearbox has a precise gear ratio of i = 200: 1, and convinced the aerospace engineers immediately. The swivel mechanism consists of a hollow shaft mounted on two ceramic bearings and driven by the TorusGear, where the Torus gear wheel is an integral component of the hollow shaft.
The success sto1y of the TorusGear is now being continued on Earth. With entirely terrestrial, tangible benefits for you. For example, the compact, backlash-free gear ratio of up to i = 400:1 in a single stage. Thanks to its extraterrestrial experience and requirements, the TorusGear also has significant installation space advantages. lts torsional rigidity and transmission precision are also out of this world.

One great advantage of the TorusGear is precisely the fact that it can be flexibly adapted to your requirements and wishes in difficult environmental conditions. And always offers a perfect solution. Turn our Martian skills to your advantage!
