Best Examples of development competence

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
weather conditions.

ttv mechanical face seals

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.

Facts and figures

Service life increased by over 32 %
Entry of aggressive media prevented
Option of individual adaptation of material, shape and load capacity depending on the particular application

ttv cassette seals

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.

Facts and figures

26 % increase in temperature stability
Labyrinth of seals for high levels of leak-tightness
All sizes and specifications are possible
Low demands in terms of the rotor shafts
Good, simple handling for replacement and repair

ttv special slide bushings

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.

Facts and figures

16 % increase in pressure load
Improved primary lubrication and interval lubrication
