Precompressed rubber inserts eliminate backlash
The DCB-GS rubber in compression coupling is a zero-backlash, very low maintenance unit specifically designed for use in generator set and general diesel drive applications.
Engine manufacturer approves couplings
Wartsila Vaasa, a Finnish engine manufacturer, has placed an order for 52 of Renold Hi-Tec's rubber-in-compression DCB-GS couplings.
The DCB-GS is based on the industry-proven DCB range and offers considerable advantages over the standard product, including a 30% reduction in weight and a reduction in overall length.
On top of its fail-safe, long life design, a significant feature of the DCB-GS coupling is its ability to control resonant torsional vibration, resulting in low vibratory loads in driveline components.
As with all Renold Hi-Tec couplings, the DCB-GS is robustly constructed for optimum durability and flexibility, and precompressed, moulded rubber inserts minimise backlash and prevent metal-to-metal contact during torque reversal conditions.

Coupling range expands to new applications
Renold Hi-Tec Couplings is set to extend both the size range and applicability of its popular high temperature blind assembly coupling, the HTB.
Couplings are crucial to temporary power
Halifax-based Renold Hi-Tec Couplings has helped provide temporary power for what is claimed to be the world's largest floating oil production, storage and off-loading unit.
Fully dynamically tested, the DCB-GS has been found to withstand 20,000 full torque reversals without evidence of damage.
Torsional stiffness is similar to that of the original DCB, however the DCB-GS may be tuned independently for lower torque stiffness and can accept nominal torque ratings up to 846kNm.
Standard DCB rubber blocks are used in the product, with a full range of rubber compound options available for optimum stiffness and damping.
The coupling has been approved by all major survey societies and is ideal for power generation pumps and reciprocating compressor applications, where long life, fail-safe operation and control of resonant torsional vibrations are essential.
Complementing the DCB-GS coupling, Renold will display its new extended range of HTB high temperature blind assembly couplings.
Now capable of handling torques of up to 40kNm, the HTB is designed for both free standing and bell housing applications, and has a high temperature capability of up to 200C.
With its unique blind assembly configuration and intrinsically fail-safe design, the HTB offers unrivalled noise attenuation abilities and lowest lifetime costs.
Ideal for large pleasure boats/workboats applications, the HTB can also be used for pump sets and compressor applications.
Renold Hi-Tec will also exhibit the new extended MSC range of marine couplings - now in torque ratings from 63 to 125kNm.
The MSC is an innovative coupling designed specially to satisfy the requirements of marine propulsion drives by providing low linear stiffness, high misalignment capability and control of resonant torsional vibration with intrinsically fail-safe operation.
The DCB-GS, HTB and MSC couplings are available now from Renold Hi-Tec in the UK and Renold agents worldwide.
