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.
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.
Described by Renold engineers as a "quart in a pint pot", 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.
Incorporating a 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, while precompressed, moulded rubber inserts minimise backlash and prevent metal-to-metal contact during torque reversal conditions.
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 DCB-GS is available now from Renold agents worldwide.
