PROPE Brunvoll Propeller Developing the optimal propeller for each application – from icebreakers to cruise ships – demands the skills of a specialist. The design process involves simulation and calculations using advanced computer modelling systems. The flows around the thruster gear housing and propeller as well as the interaction between the thruster and the hull are highly complex. Backward skew

ELLERS Design for performance Full-scale experience and model testing are needed to validate the calculations. The design process involves expertise in mechanical engineering and metallurgy as well as insight into the operation of electro-hydraulic control systems. Each customer has specific needs and preferences. We listen. For complicated and challenging applications, Brunvoll’s thruster expertise is unmatched. Kaplan

TUN THRU Small or large – a compre Refined continuously through 4 thruster generations Since 1965, we have delivered thousands of tunnel thrusters for fishing, cruise, naval, merchant and offshore vessels – a success story for generations. We focus on developing ever more reliable, optimized and cost-effective systems • nhanced gearbox for optimal hydrodynamic performance. E • obust gear maintains optimum tooth contact R in various operating conditions. • ore compact propeller hub. M • alanced backward skew blades minimize servo B and excitation forces. • eplaceable blade bearing liners. R...

■ Pinion shaft seal Radial lip seal with Supreme technical solutions I "--- ,r I! ad Brunvoll introduced propeller shaft sealing systems with a safety chamber and multiple seals as early as 1965 Medi um pressure servo systems hydraulics reduce noise levels Cost efficient, easier installation and maintenance, higher reliability and extended lifetime. Quieter than a high-pressure system. Precise Manoeuvring A variable displacement pump delivers the exact amount of oil needed for the propeller pitch movements. The valve mechanism automatically adjusts the oil flow to enable smooth and...

Internal inspection of gearbox - through dedicated pipe using fibre optics. Inner radial seals Each side of the two inner lip seals is oil lubricated. This provides ideal working conditions and extends the lifetime. The lip seals run against a specially treated replaceable shaft sleeve. Neither the seals nor the propeller shaft are exposed to seawater. Rope guard Protects the propeller shaft sealing system from ropes and other foreign objects. Propeller blade seals V-lip seals for optimal sealing performance. Adapt to the profile of the metal as it wears Pitch mechanism by link arms The...

No short cuts which cause trouble Inadequate sealing systems – may allow seawater to enter the thruster – the most frequent cause of thruster failure. Seawater in the oil can destroy gears, bearings and other vital components inside the unit. Stripping essential features – such as the rope guard – exposes the propeller shaft sealing system to damage from debris. – for example by stretching the length of the gear teeth – causes overloading of the gear. Without a rope guard, shipowners must consider other means of protection. This shortens the lifetime and increases maintenance costs. If a...

Yes to Brunvoll quality solutions Brunvoll’s multiple sealing system with an outer seal, inner seal and safety chamber keeps seawater out of the thruster, increasing the lifetime of the seal. The intermediate safety chamber makes it easy to monitor the seal condition. Brunvoll thrusters are fitted with rope guards as a standard feature to protect the propeller shaft sealing system from ropes and other foreign objects. At Brunvoll, we design the gear and mesh to generous specifications that ensure high endurance and maximum component life. Relative thrust factor Optimum contact patterns...
