ttv Engineering Solutions is establishing itself as a partner for customer-specific product solutions in the mechanical engineering sector!

The mechanical engineering sector is continuing to experience dynamic development, with “Made in Germany” machines and systems well sought-after on the global market. Based on its own information, the VDMA (Mechanical Engineering Industry Association) is forecasting further success for 2018, with a growth of around 3%. This is primarily a result of the strong demand from the German domestic market, where German customers are already complaining of bottlenecks in delivery deadlines for systems and machines.

Quality as a driver of success

In its journey to success, the mechanical engineering sector has never accepted any compromise when it comes to quality and innovation. As a result, it has always been able to develop features that set it apart from an extremely wide range of competitors on the global market, while also making sure that these features are economically beneficial.

These very same features are equally important for partners in the supply chain: innovative solutions, the use of new materials and unconventional ideas on increasing quality and service life.

Where standard products just won’t do, that’s where product-specific solutions come in

It is precisely these market requirements that mean that components are now increasingly being developed to be customer and product-specific. The reasons for this are clear: standard products are increasingly unable to meet the demand of creating customer-specific differentiating features while significantly increasing performance and service life compared to the competition. ttv is addressing this fact with a dedicated development department for customised product solution, which it has called ttv Engineering Solutions.

Relatively new additions to the portfolio include drawing-based production parts from CNC processing, which ttv produces together with long-term partners in any defined quality on the request of a large number of customers.

Engineering Solutions: ttv is the right specialist for customer-specific solutions.

Customer-specific solutions – they’re really special to ttv. Therefore, it should come as no surprise that ttv has made a name for itself as a mechanical engineering specialist with its seals and slide bearings.

For ttv, typical challenges include applications relating to pumps, drive units, transmission gearing and motors. Very often, it is simply a question of increasing the service life while ensuring process reliability, thereby reinforcing the quality commitments to the customer.

The type of solutions that could be sought after here include continuous operation with increased temperature development or high levels of friction with proven leak-tightness. With outdoor applications, customers are often looking to permanently prevent the ingress of dust and moisture.

This development on the market lead ttv to the decision to pay more attention to customer-specific product solutions and to set up a separate development department. To make sure that it has sufficient capacity for short-term projects, ttv has set up an experienced team of technology and engineering specialists, and it attends to every conceivable parameter within a project. Looking at the shape, design, structure, material properties and the mixture of materials are various ways in which performance can be improved and demonstrable added value created.

Best examples of development competence

Seals and slide bearings are usually only comparatively small components in the area of technological components and assemblies, but it is often the case that these C-parts have a huge influence on the service life and functionality of components in the mechanical engineering sector.

Customer and project-specific solutions from ttv have lead to demonstrable and significant increases in service life, temperature resistance, friction properties and leak-tightness over recent years.

Seal for use in high-pressure cleaners

High-pressure cleaners are under enormous amounts of strain due to high working pressures and because they are often used in continuous operation.

In this example, the aim was to meet the requested service life of 1080 operating hours during an endurance test, without any leakages.

To this end, endurance runs were carried out on the customer’s test benches with the sealing rings developed by ttv, with all series conditions in place. These included stop-start sequences at 25-second intervals with pressurisation and a 5-second pause, or axial movements over 7 mm and 4000 rpm on the swash plate.

Facts and figures

  • 100% compliance with the defined customer requirements
  • Additional price advantage
  • Establishment of a reliable supply chain for global distribution

ttv shaft sealing rings for transmissions in looms

Shaft sealing rings for mechanical engineering are a typical example of ttv’s problem-solving expertise. According to the customer requirements, significantly longer service lives for the motor and transmission were right at the heart of their objectives. Previously, these longer service lives had lead in part to a huge amount of shaft run-in, sealing lip wear and leaks.  

The ttv developers drew on the geometry and material of the shaft sealing rings, and optimised them in accordance with their use. The fillers used in the compound and the applied radial forces were set on the test bench in continual operation at the laboratory.

Facts and figures

  • Significant increase in service life of over 22%
  • Perfect balance in terms of the pre-tension (sufficient to meet requirements, but does not go beyond the necessary level), combined with adapted springs
  • Modified compound with significantly better material properties

A solution for every requirement

ttv sees excellent potential for the manufacturers of machines and systems with regard to increased performance, thanks to seals and slide bearings classed as C parts without a large cost volume.
