The following animation demonstrates a custom-designed and manufactured U-configuration linear actuator.
We created this highly specialised system for application in an oceanic environment. The actuator itself utilises a combination of advanced mechanical components, including a servo drive, an inline planetary gearbox, and a ball screw mechanism, to achieve precise linear movement while maintaining high load-handling capacity.
Driving the actuator's movement is a servo drive, which provides precise control over the movement. The servo drive is coupled with an inline planetary gearbox featuring a 5.5:1 reduction ratio. This setup ensures that the actuator can deliver high torque at low speeds, making it suitable for applications requiring precise positioning and controlled motion.
The 5.5:1 reduction ratio in the planetary gearbox allows for the multiplication of torque, enabling the actuator to manage heavy dynamic loads efficiently while maintaining smooth operation.
Following the servo drive and planetary gearbox, the motion is transferred through a set of spur gears. These gears are arranged to provide a 2:1 reduction ratio.
The main spur gear is directly coupled to a ball screw, allowing the transformation of rotational energy into linear motion. The 2:1 reduction ratio further enhances the control and precision of movement, making it ideal for applications that demand accurate positioning under varying loads.
The ball screw is a critical component, providing smooth and precise linear movement. Mounted onto the main spur gear, it translates the rotational motion into linear displacement, enabling the actuator to extend or retract with high precision.
The use of a ball screw ensures minimal friction and wear, which is particularly beneficial in applications where high load capacity and durability are required. The actuator is capable of operating at a dynamic load of up to 50 kN, making it suitable for tasks that involve substantial forces.
The actuator is mounted each end between two clevises, which provide secure attachment points and allow for controlled movement. The design incorporates an anti-rotation feature provided by the installation framework, preventing unwanted twisting or rotation of the actuator during operation. This feature ensures that the linear motion remains consistent and reliable, even under dynamic conditions.
Designed for use in harsh marine environments, this linear actuator features a sealed housing that protects internal components from saltwater, corrosion, and other elements typically encountered in oceanic applications.
All external components that are not painted are made from stainless steel, providing exceptional resistance to rust and corrosion. This choice of material enhances the actuator's longevity and reliability, making it well-suited for long-term use in challenging conditions.
This heavy duty linear actuator is tailored for applications that require precise control of heavy loads in demanding environments. Its design makes it particularly suitable for marine applications, such as:
Ship Steering Mechanisms: The actuator's ability to handle high loads and its robust sealing make it ideal for controlling rudders and other critical steering components on vessels.
Offshore Energy Production: Its corrosion-resistant design allows it to operate reliably in offshore platforms, where exposure to saltwater and extreme weather conditions is a constant challenge.
Subsea Robotics and Exploration: The actuator's precision and strength make it a valuable component in remotely operated vehicles (ROVs) and other equipment used for underwater exploration and maintenance.
This heavy duty linear actuator is a high-performance solution designed to meet the rigorous demands of challenging environments.
With a servo-driven planetary gearbox, ball screw mechanism, and stainless steel construction, it delivers precise linear motion while handling loads of up to 50 kN.
Its robust design and advanced features ensure reliable operation, making it an ideal choice for applications where precision, durability, and resistance to harsh conditions are paramount.
