INDUSTRI 9 Mechanical Power Transmissions …

1 Power Transmissions Worldwide2 INDUSTRYK umeraKumera Drives Oy and Kumera AS are members of the Kumera former specialises in the manufacture of industrial Mechanical powertransmissions for onshore applications. Marine Transmissions and specialapplications are designed at the Kumera AS plant in Sandefjord. The Design and Applications team has been particularly successful with tailor made solutions for specific Mechanical transmission requirementsof customers, worldwide.

Mechanical drive units are importantcomponents of a production line. A failure in adrive unit will cause immediate problems in lossof production. This is a major consideration forKumera. Being a manufacturer of Power trans-mission equipment, Kumera has activelydeveloped its standard gear units to meet theseneeds and in co-operation with customers, driveunits for their products and customised gearunits for new AGITATOR/MIXER DRIVESCUMPACT BEVEL GEARS WITHMOTOR AND HOLLOW SHAFTCUMPACT HELICAL GEAR UNITSCUMERA CHIPPERGEAR UNITSCUMERA RIGHT ANGLEGEAR UNITSCUMEX COUPLINGS AND NORGEAR HYDRAULIC new world wide source for powertransmissions including a gear selectionprogram for customer ANODE JACKS FORALUMINIUM INDUSTRY4 MARINESTANDARD DESIGNS FOR Fi-Fi APPLICATIONS The most economical solution to provide Power to a firepump of Fi-Fi I, II or III class is to utilise the main enginefree-end PTO when the propulsion loading is light.

2 Kumera AS has a standard range of compact singleinput/single output gearboxes with built-in oil operatedclutch. The gearboxes are offered with horizontal- and vertical offset vessels with a towing capability, a combination gearbox with twoclutched output shafts permits individual control of a fire pump andtowing winch hydraulic solution can have additional benefitsin the overall machinery installation as it can reduce the auxiliary load. When engine speed and fire pump speed are compatible, a simple clutchunit can provide the drive to the fire pump. Our NKHU oil operated multi-disc clutch offers a compact transmission, capable of engagement at allengine speeds. Some integrated fire pump and gearbox designs are available. NORGEAR MULTISHAFT GEARBOXNORGEAR STANDARDFI-FI I GEARBOX5 NORGEAR MULTISHAFT GEARBOXESNORGEAR RIGHT ANGLE GEARBOXESNORGEAR PARALLEL SHAFT GEARBOXESThe principal application is the drive to a steerablepropulsion unit. This most commonly takes the form of aright angle gearbox (horizontal input/vertical down output)type KVIV with or without a built-on hydraulic clutch.

3 On vessels with a high electrical load, a single input twinoutput parallel shaft gearbox offers a clutched drive to anazimuth unit and a continuous running drive to a shipservice alternator. Parallel shaft reduction gearboxes type FV permit highspeed engines to drive cycloidal propellers at optimumspeed and by use of a vertical offset can eliminate theneed for cardan shafts and simplify the propeller shaft line. Tunnel thrusters with diesel drive incorporate a bevelgearbox with horizontal in/vertical down shaft positions can facilitate the siting of anelectric drive motor in a restricted thruster-room space. A free standing hydraulic clutch unit type NKHU in theshaft line to an auxiliary thruster can permit the engine tohave a secondary function an alternator drive. Thesame unit would provide isolation on a water jet drive formaintenance and safety. Kumera AS deliveres gearboxes with a dual clutch, twospeed arrangement for PTO/PTI operation. GEARBOX AND CLUTCH UNITS FOR PROPULSION AND AUXILIARY THRUST 6 Offshore and onshore installations offer many applicationsfor right angle gearboxes ranging from standard reductionunits for water supply or irrigation pumps to more complextypes such as Kumera RA designed to meet the standards ofthe oil industry.

4 These gearboxes incorporate a hollow outputshaft to accommodate vertical adjustment of the pump shaft,thrust bearing sized to take the axial thrust and weight of thepump rotor and a back stop on the output shaft. Being a specialist gearbox manufacturer our gearboxes are easily adapted into dredge vessel applications.
