Best Examples of development competence

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.

Shaft seals for gearbox

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
