What are the main functions of blocking systems for propeller shafts?
Blocking systems for propeller shafts primarily serve to secure against uncontrolled rotations, especially during maintenance work or in emergencies. They ensure operational safety and protect the drive components from damage.
What types of blocking systems are there and where are they used?
Common types are mechanical systems (robust, e.g., disc brakes with over 1 million cycles), hydraulic systems (high blocking forces up to 200 bar) and electric systems (precise control, response time <100 ms). Areas of application include shipbuilding, industrial plants and wind turbines..
What should I pay attention to when selecting a blocking system for my propeller shaft?
Important criteria are the compatibility with propeller type and drive system (e.g., Volvo DPH/DPI), the maximum torque, the environmental conditions (e.g., corrosion risk in maritime applications), the available installation space, and the desired level of automation. A thorough analysis of operating conditions is essential.
Why is material selection so important for blocking systems for propeller shafts?
Especially in maritime applications, materials such as stainless steel or special bronze alloys must be corrosion-resistant . The materials must also withstand the high mechanical loads and torques to guarantee a long service life and reliability.
What role do classification societies like DNV GL play in propeller shaft blocking systems?
Classification societies like DNV GL, Lloyd’s Register, or ABS define standards and requirements for the safety and reliability of ship components, including shaft brake systems. Certification, for example for shaft brake systems according to DNV GL, confirms the conformity with these high standards..

Introduction to blocking systems for propeller shafts
Uncontrolled movements of heavy propeller shafts, especially during maintenance, pose a safety risk. Precise control and reliable locking are fundamental for operational safety and efficiency. Special propeller shaft locking systems, such as shaft brake systems according to DNV GL, are established; failures incur significant costs.
Requirements vary greatly: from yacht propellers to cargo ship shafts (over 70,000 Nm torque) or arctic applications requiring special materials. The selection of suitable locking devices for ship shafts requires an analysis of operating conditions and load profiles. ATEK Drive Solutions offers brake systems with integrated locking units..
Modern blocking systems for propeller shafts also allow controlled deceleration or positioning. These enhanced functions increase operational flexibility and longevity of the drivetrain. Sensors for status monitoring support proactive maintenance.Technical fundamentals and functional principles
Operating principles of blocking systems
blocking systems for propeller shafts function by converting or dissipating rotational energy to safely prevent movement. The core principle of these safety systems for drive shafts is based on mechanical, hydraulic, or electrical working mechanisms, often combined. An example is corrosion-resistant brake units for marine applications..
- Working principle: Conversion or dissipation of rotational energy to prevent movement.
- Core mechanisms: Based on mechanical, hydraulic, or electrical principles, often combined.
- Mechanical systems: Robustness and high cycle numbers (e.g., ATEK >1 million cycles).
- Hydraulic systems: Generation of high blocking forces (up to 200 bar).
- Electric systems: Precise control and fast response times (<100 ms).
- Selection criteria: Depending on holding power, installation space, environment, and level of automation.
- Areas of application: Shipbuilding, industrial plants (fans, test benches), wind turbines.
Types of blocking systems
Mechanical systems (e.g., disc brakes) are robust (ATEK components >1 million cycles). Hydraulic systems provide high blocking forces (up to 200 bar). Electric systems allow precise control (response <100 ms). The choice of types for locking devices for marine drives depends on holding power, installation space, environment, and level of automation.
Areas of application
In shipbuilding, they secure propeller shafts (e.g., up to 72 kNm with 72 kNm shaft brake systems). Industrial applications include fans or test benches. In wind turbines, they block rotor shafts (service life >20 years). Their versatility makes such blocking systems for propeller shafts key components.Selection criteria and compatibility
Compatibility with propeller types and drive systems
The adjustment of the blocking system for propeller shafts to propeller type (fixed pitch, controllable pitch, pod drives) and drive system is crucial for functionality. Interfaces, torque curves, and dynamics are relevant. ATEK’s modular system allows suitable solutions, e.g., for Volvo DPH/DPI drives.
Material selection and load capacity
Corrosion-resistant materials (stainless steel, bronze alloys) are essential in maritime applications for locking mechanisms for ship propellers. The system must accommodate maximum torques (safety factor 1.5-2.5). FEM analyses verify the integrity of industrial brakes..
