Reduction gearbox with inverter / clutch for ships
MM W2700 -/NR (3.5 -> 6.04:1 - 841 hp max. @ 2200 rpm)
Masson Marine
All our gearboxes are symmetric with respect to the direction of rotation; the output shaft may run in engine-wise direction or in counter-engine-wise direction in the ahead mode of the ship.
Masson-Marine transmission names are composed as follows:
First part of the name:
* MM: Masson-Marine
* W: "workboat", as our gearboxes are designed for professional applications in continuous operation
* Number: this is the model type; the higher the number, the higher the power ratio that can be transmitted
Last part of the name:
* (No extension): The gearbox is a standard gear with vertically offset input and output shaft lines.
* NR: "non reversing" - this transmission is a clutch/de-clutch gearbox (no reverse gear).
* CEW: "counter-engine-wise" means that the direction of rotation of the output shaft is the opposite of the input shaft rotation.
* EW: "engine-wise" means that the input and output shafts rotate in the same direction.
* C: "coaxial". The input and output shaft lie in line with one another.
* DS: "dual speed" - this gearbox has two different reduction ratios
All our transmissions can be adapted to CPP, i.e. be built as non-reversing clutch/de-clutch transmissions.
Options And Special Features
Our gearboxes have a reliable and steady hydraulic system, and strong casings machined with high precision. They are suitable for continuous heavy-duty operation.
As an optional equipment, we can also supply the engine coupling, the propeller shaft coupling flange with registering coupling bolts, and "bell housings".
