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.
ttv shaft seals for use in solar parks
The requirements were clear: The new shaft sealing rings needed to withstand a wider temperature range and meet these criteria with multiple sealing and dust lips.
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.
Facts and figures
Customer release for the extended temperature range with all defined lubricants, particularly in the low-temperature sector classed as critical
Substantially optimised solution with axially acting dust lip in addition to the radial lip to act as a dust seal between transmission and flange

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
Managing Director Harald Nitzschke sees enormous potential for drive technology manufacturers in the areas of service life increases and the temperature resistance of gearboxes, engines and other functional components, where ttv is the perfect solutions partner.
