Shrink discs in marine technology
Shrink discs provide a secure, backlash-free and force-locked connection between shafts and hubs. They are frequently used in marine propulsion systems to connect propeller shafts to gearboxes or engines. Thanks to their easy assembly and disassembly, shrink discs significantly reduce maintenance times and costs. They are made of corrosion-resistant materials that can withstand the harsh conditions at sea.
Advantages of shrink discs in marine technology
High torque transmission
Durability and reliability
Easy maintenance and replacement
Corrosion-resistant materials
Shaft couplings in marine technology
Shaft couplings connect two shafts, for example a propeller shaft with the shaft of a gearbox. They are essential for reducing vibrations and improving the smooth running of the drive system. Various types of shaft couplings are used in marine technology, including flexible, rigid and elastic couplings.
Advantages of shaft couplings in marine technology
Compensating for misalignments and reducing vibrations
Increasing the service life of drive components
Improving the smooth running and efficiency of the drive system
Easy installation and maintenance
Frequently asked questions
What is a shaft coupling and what is it used for?
A shaft coupling is a connecting element that connects two shafts to transfer torque from one shaft to the other. It is used to ensure a continuous, smooth transfer of power and motion between the shafts, and can also compensate for axial, radial or angular misalignments. Rigid shaft couplings do not allow for any axial, radial or angular movement between the shafts, resulting in a very precise and direct power transfer. The main principle of a rigid shaft coupling relies on a fixed connection between the shafts being connected. This is achieved by means of mechanical couplings, such as feather keys, splines or clamping rings. The rigid design ensures that the torques and rotational speeds can be transmitted with almost no loss.
What factors need to be considered in terms of corrosion resistance?
The corrosion resistance of a material is influenced by several factors, including chemical composition, environmental conditions (e.g. humidity, temperature, pH value) and mechanical loads. These factors must be carefully considered when planning and selecting materials.
Can the shrink discs also be manufactured with a class approval?
If required, TAS Schäfer products can also be supplied with the approval of a classification society or comprehensive documentation from our own measuring centre. This is often a requirement for the use of our products, especially in marine technology. Our engineering team is therefore on hand to provide support during the design phase to ensure a smooth process during the approval process.
