A leading manufacturer of remotely operated vehicles (ROVs) for the oil and gas industry fully relies on the SK1 series safety couplings. The SK1 is installed in an automated mechanical torque tool in an ROV which works down to extreme depths. The torque limiter is used to unlock the external arm, which in turn has the task of opening, closing, and repairing oil valves in deep water.
R+W received a customer inquiry which turned into an exciting project for our development team, a flange mounted safety coupling (STF). Normally this is nothing out of the ordinary, but in this instance a special marine certification was required. The requested STF safety coupling must be maintenance-free and will be installed in a ship’s propulsion system to protect the gearbox on the bow steel rudder.
BACKLASH FREE TORQUE LIMITERS
(WITH FULLY SPLIT CLAMPING HUB)
0.1 – 2,800 Nm
fits to the same motor sizes than 2K 800 but is advanced for high cutting force and power
Precision line shaft couplings (also known as link shafts, connecting shafts or torque tubes) are used for spanning longer distances between rotating components
Metal bellows couplings are especially suitable for highly dynamic direct drive applications. The stainless-steel bellows compensates for lateral, axial, and angular shaft misalignment with very low restoring forces and accelerates with a low moment of inertia.
A lifting and lateral-pushing system is a space-saving solution which allows truck drivers to load and unload containers without the need for additional team members or forklift trucks.
Linear chain is a space saving solution for significant lift
A New Zealand manufacturer uses innovative cooling technology and utilises the Grob Linear chain, suited to sub-zero temperatures, for processing
For the project a special ST2/100 safety coupling was selected with a disengagement torque of 80,000 Nm
