These days, the agricultural engineering sector is characterised above all by high-tech solutions, and the complexity of this technology has meant that there has long been a shortage of skills in this area, as has already been seen in other technology sectors. Field robots and GPS-supported tractors are conquering farming and marking a digital revolution.
Although this sector is relatively small compared to the mechanical engineering or automotive sectors, Germany is one of the leading countries in this field in terms of technology, with an export share of over 70 %.
There is a good reason behind this change towards increasing productivity. The world population is continuing to increase, and people need to be fed. According to estimations by the UN, the number of people living on earth will increase from the current figure of around 7.5 billion to 9.7 billion in 2050.
A combine harvester can harvest 100 tonnes of grain every hour, supplying a city with bakery products all day long. But even these impressive figures aren't enough to feed the growing world population.
Therefore, it is up to the agricultural engineering sector to further increase the productivity of the machines and to use digitally supported technology to increase efficiency in land management.
The agriculture industry also has to face major societal challenges, with consumers from industrial nations increasingly demanding organically produced products while the amount of available agricultural land is decreasing.
The requirements in the field of agricultural engineering are clear: Increased productivity, more output, larger area throughputs and increasingly intelligent solutions with assistance systems for the operators of agricultural machinery. There is no magic solution here though, as it is also important to ensure a very good price-to-performance ratio in an extremely competitive world market.
The variety of products used in agricultural engineering is huge. These products range from tractors and sowing machines to harvesting equipment, combine harvesters, feeding technology and soil-cultivating machines right through to manure technology and small tractors such as those used for managing the land in vineyards.
This wide variety of products and the high strains put on the technology call for maximum quality and individual solutions, both from the machine manufacturers and from the suppliers of components and assemblies on the market. These high demands also mean that the number of engineers employed in agricultural and forestry engineering has almost doubled over the last 5 years, making it an increasingly interesting profession with excellent career opportunities, including the chance to work abroad.
Over recent years, we have further established ourselves as a specialist in agricultural engineering, with our two competence fields of seals and slide bushings. For us, typical challenges include applications relating to drive trains, transmission gearing, ring gear seals and axles. Standard products from stock are often not adequate in dealing with the enormous strains cause by mud, heat, cold, sand and dust, and the increased land management and the introduction of multiple annual harvests mean that more strain is automatically being put on the materials.
This clear development has lead to the strategic decision to set up a separate development area for customer-specific product solutions, with substantial capacity to support our customers. We have an experienced team of specialists in the fields of technology and engineering working in this new area, and we attend to every conceivable detail of a project. Material properties, material composition and
design make sure that the media are kept permanently and sustainably separated from one another and that the elasticity and functionality are retained even under extreme
Despite only being small components, seals and slide bushings are often crucial for the service life and functionality of today's machines and
vehicles. In recent years, ttv has designed a wide range of different solutions that have lead to significant increases in service life and temperature resistance.
Inspired by the excellent results in other industries, our technicians have developed new mechanical face seals that have increased service life by over 32%. Installed in a split housing, the ttv mechanical face seals are pressed together with lapped running surfaces. An O-ring (NBR/FPM etc.) is usually used as a preload element, which fixes and aligns the seal inside the housing. Aggressive and abrasive media are prevented from getting into the seal, making it possible to guarantee increased wear resistance and service life.
It's a similar story with the customer-specific cassette seals. Self-contained, pre-lubricated and with multiple sealing lips, these seals form a kind of labyrinth of seals. The actual sealing lip runs around a processed running surface in the inside of the seal, meaning that there are fewer demands placed on the shaft seat. The use of different materials for the component has increased the temperature load by 26% to 108°C, which has impacted on the service life in equal measure.
Our engineers have also been able to meet the increasing requirements in the area of slide bearing technology, in collaboration with our customers' development and design teams. This related to the improved application of the ttv-090/ttv092 or CuSn8 slide bushings. The desired results were achieved by the introduction of special oil grooves, modified clamping dimensions and design improvements.
Anyone looking for innovative and noticeably better product solutions in order to stand out in the highly competitive agricultural engineering market would do well to come to ttv. We can find a solution to any problem. Give us a try!
