We reinvent the wheel every day.

Innovative gear technology for custom solutions

Whether you need durable plastic gears, high-precision spur gears, quiet cross-helical gearboxes, or fine worm gears – we offer customised solutions to meet your requirements.

Our expertise lies in finding the perfect geometry for your gears, whether they need to be extremely quiet or very small. We combine a passion for precision with cutting-edge technologies and the latest software programs, such as reverse engineering.

Additionally, we conduct tribological studies and optimise noise levels and load-bearing capacity to create products that embody durability and reliability.

Discover the variety of our solutions and rely on our many years of experience in gear technology.

 

Products

Spur gearing

Spur gearing transmits motion evenly – even if there are variations in the distance of the axes from the pinion and gear – and also offers excellent efficiency. Modifications to the gearing geometry can be made to increase the load-bearing capacity and reduce the noise level. They can be integrated into production with no additional effort and at no extra cost – right from the outset. 

Cross-helical gearbox

To achieve the gear ratios required for the gearbox shown here, a lot of functionality had to be packed into a tiny space. This presented complex challenges in terms of manufacturing and measurement technology, with a gear ratio of almost 1:5,000, a normal module of less than 0.2 and skew angles of up to 48°. This gear is used in a rotation angle sensor.

Worm gears and cross-helical gears

Worm gearboxes and cross-helical gearboxes enable large ratios in small spaces and with a low noise level. We already manufacture various models, such as cross-helical gears with any skew angle, any axial crossing angle, and even every possible edge shape. Sample worm from a sensor gearbox

Crown gears and bevel gears

Crown gears and bevel gears are used in non-parallel axis positions from the drive and output side. In a crown wheel gearbox, the pinion also takes the form of a spur gear. Thanks to our computing and manufacturing technology, we can provide all crown gear and bevel gear variants (straight and helical toothing, with and without axial offset). Virtually any axial crossing angle can be selected. We can also design bevel gears with curved teeth. A good illustration of this is our combined spur and crown wheel gearbox.

Our test beds:

Reliable data for sustainable performance

When answering the question ‘how?’, a single attempt is often not enough. In our in-house testing facility, we collect comprehensive data during tests, providing a basis for well-founded statements on service life and operational behaviour. These valuable insights are seamlessly integrated into the further development and production process to ensure that our products meet the highest standards.

By virtue of our test beds, we can closely monitor and optimise the performance of our products to ensure long-term reliability. We rely on precise data collection and analysis to ensure our customers receive the best possible solutions.

Gear and material testing

Mechanical tribological testing

Pin – disc – test bed in tribological testing

We perform material testing in the following core areas: Tribological and mechanical strength of gears

Friction and wear behaviour of any material pairings.

Certain issues in relation to materials testing require external expertise. We use synergies and maintain contacts with the university research community for this purpose.

With a nominal speed of up to 6,000 rpm on the pinion and braking power of up to 1 KW, we can cover a very large load range for gear speeds thanks to infinitely variable control. We use test gears in accordance with VDI 2736. Moreover, we can combine these mechanical parameters with thermal ones, as we also have access to a heating chamber with a very wide temperature range. Our test beds feature temperature, moisture, and torque measurements for recording the results.

The test bed can be operated at speeds of up to 3,000 rpm for testing various material combinations. The torque of 3.5 Nm can produce a resolution in the per mille range of the nominal torque. A thermographic camera can be used to measure the heat input from the load in the combination. Our system is also equipped with a temperature and moisture sensor. Wear can be measured with an accuracy of 0.2 μm using a displacement sensor.

 

Technologies

Analytical, numerical, or structural?

By analysing your idea and combining it with our experience and the right tools, we create the optimal feasible solution for you. Supported by software, test data, and experience, we endeavour to implement your priorities in the best possible way.

Gear and gearbox optimisation: Perfection through precision engineering.

You define the performance requirements for your gears and gearboxes. Every product is the result of a well-thought-out process. Utilising our precision engineering, we continuously optimise things until the result meets your expectations and requirements.

You receive parts from us that can be seamlessly integrated into your production process.

THE POTENTIAL FOR OPTIMISATION:

THE RIGHT GEARBOX

Designing gears and gearboxes involves keeping track of numerous different requirements at once. To us, achieving the required gear ratio, taking into account the position of the input and output shafts in a specified installation space, is the start of the optimal realisation of your requirements. 

REVERSE ENGINEERING:

A PROVEN PRINCIPLE

MEETS MODERN METHODS

In order to achieve the desired gear performance, its form must be geometrically fine-tuned. By using precise measurement technology and with the help of computer tomography and coordinate measuring machines,
we can obtain the measurement data needed for corrections. 

We use specially developed reverse engineering software to convert the measurement values into corrections of the injection moulds, which enables us to optimise even complex forms.

Thanks to our high-precision tool manufacturing technology, we can reproduce form corrections precisely in the injection mould – including selective corrections to each individual tooth.

The benefits for your product are clear: you end up with a better quality product which is ready for production more quickly.
