Compact solution for smallest mounting spaces
CENTA presents its new CENTAFLEX-M-127, a compact solution accommodating smallest mounting spaces. The CENTAFLEX-M-127 series has been designed especially for motor boat and yacht applications. Reducing the outer diameter while maintaining an unvaried high performance: A formula that meets the demand for compact dimensioning of drive train components.
The elastic mounting of the engine is the first step when limiting the noise level aboard a boat. But this is not enough. For gear and rigid coupling will transmit vibrations and structure-borne noise to the hull of the vessel. Only a flexible coupling between gear and propellor shaft provides sufficient damping to effectively decrease noise levels on board. However, the space available for replacing a rigid connection by a flexible coupling is very limited in most cases.
CENTA’s newly developed CENTAFLEX-M-127 provides a compact solution especially for such applications and covers a torque range of up to 250 Nm. The flexible coupling provides the perfect component for applications with limited mounting space behind the gearbox due to its compact design and subsequent elimination of additional components like spacers. By relocating the fail-safe device into the inside of the coupling we have been able to reduce its outer diameter by about 15 % while maintaining the performance at the same level.
Very smooth transmission of torque and propeller thrust is ensured by a large volume of rubber used in this torsionally flexible zero-backlash coupling. A feature that reduces not only the noise level but also goes easy on a ship’s electronic equipment by cutting down vibrations. Since the CENTAFLEX-M-127 also compensates misalignments of all kinds, particularly angular, it additionally reduces wear on shaft bearing and gear box.
As for all CENTAFLEX marine couplings, the CENTAFLEX-M-127 is fastened to the cylindrical propeller shaft by means of a securely dimensioned clamping hub. No more time-consuming and laborious machining of the shaft. Even length adaption on site is simple. The propeller shaft diameter is not impaired by bore or keyway. Flange connection and hub respectively adapter flange will be delivered fully machined for immediate installation.
The CENTAFLEX-M series is available in two sizes at short notice: for about 40 HP (CF-M-127) and for 80 HP (CF-M-160), depending on the propeller shaft speed.
