Innovations arising from robot technology are important success drivers in the competitive global market for drive technology. Suppliers have to deal with requirements such as longer service lives, increased quality and increased functionality.
For us as a company, this means finding new solutions with regard to material, geometry and structure in a way that is both inventive and flexible. With our Engineering Solutions department, we are ideally prepared for this challenge.
The global market for drive technology is also very competitive, with performance and innovation two key success factors. The requirements for increased service life, better quality and upgraded functionality mean that all parties involved in the supply chain are under pressure to continually break new ground in their selection of materials and geometries.
High levels of competitive pressure, extremely demanding technical requirements and industry players' desire to differentiate themselves from other companies all mean that components are now increasingly being developed to be customer and product-specific. The reasons for this are clear: standard products are usually immediately available, but are barely able to strike the right balance of noticeably longer service lives, innovative strength and competitive advantages. ttv is addressing this trend towards customised product solutions with a dedicated development department.
According to a statement from Managing Director Harald Nitzschke, ttv is also offering drawing-based production parts from CNC processing in any defined quality.
Over recent years, ttv has further established itself as a specialist in drive technology, with its two competence fields of seals and slide bushings. Just a few examples of the typical challenges faced by ttv here include applications relating to drives, gearboxes, engines, pumps and valves. Customers usually start off with a very clear profile of previous experience and objectives, where the installed standard stock products are often no longer adequate to deal with the increasingly demanding requirements. These include continuous operation with increased temperature development and friction, or the exposure to dust and moisture due to outdoor applications.
This development lead ttv to the strategic decision to set up a separate department for customer-specific product solutions, with first-class capacity to support ttv customers. ttv has an experienced team of technology and engineering specialists to help with this task, and we attend to every conceivable detail of a project. Material properties, material composition and design open up numerous possibilities for improving performance, and help keep dirt, moisture and other influencing factors strictly on the outside.
Seals and slide bushings are only comparatively small components in the area of technological components and assemblies, but this does not change the fact that both product categories are often crucial for the service life and functionality of drive technology assemblies.
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.
The ttv team started by carrying out compatibility tests with customer-specific lubricants in the temperature limit range. Based on a project successfully carried out several years previously, a shaft sealing ring was then developed with the technicians and developers, with multiple radial and axial sealing and dust lips.
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.
A solution for every current requirement.
Sector
Drive technology, renewable energies
Problem
In the low-temperature range in particular, problems were occurring with the sealing rings formerly used in solar parks.
Projekt
Development of new shaft sealing rings for optimal material resilience even in an extended temperature range.
Application
Use in solar parks with huge temperature differences and changes in weather.
Requirement
Material needs to withstand the extended temperature range with 100% reliability. Test carried out solely using the lubricants provided by the customer.
Result
Advantage
Huge temperature range withstood with 100% reliability.
