REINTJES rolls out its new Down Angle gearbox series WVSA at SMM
The gearbox specialist REINTJES will present at the SMM, Hamburg its brand new product range of Down Angle gearbox series, called WVSA, the company said in a press release.
By the end of 2015 a Down Angle prototype successfully completed its first test runs at the REINTJES facilities. Especially the conical spur gears, that generate a shaft angle of 8° to 10° between the Input and output shaft of this gearbox series, were put through a hard and intensive test. With a Down Angle gearbox installed the engine room can be engineered in a space-saving design, means a horizontal installation of the main engine while the propeller shaft is sloped downwards by the inclination angle inside the gearbox. Thus, a shorter propeller shaft can be used which leads to a smaller engine room.
Special attention was paid to the teeth design and contact pattern under load in order to reduce the noise emission, which is an important selection criterion for the customer. Compared to commercially available Down Angle gearboxes, the noise values were already very satisfying during initial measurements. The so-called beveloid gear design represented a special challenge in the design, calculation and the manufacturing, but all were managed in a proper manner.
The new REINTJES Down Angle gearbox series comprises sizes WVSA 340, WVSA 740, and WVSA 1540 and is available at a power range from 250 to 3,250 kW and a reduction ratio of 1.5 to 4. Further important features include the aluminium housing and the shaft angle of 8° to 10° that is essential for Down Angle gearboxes.
