Hydro Power Planetary Gear Units

PAR/PBR planetary gear units are primarily used in the drive trains of Kaplan turbines. Their compact construction, even at high transmissions, permits a narrow turbine train with generators of very small sizes. The axial forces resulting from the operation of the turbines are absorbed by an oil-filled tilting pad bearing in the gear unit and conducted into the base via the housing. The individual segments can be inspected and/or replaced without disassembling the gear unit.

All the components are designed for permanent, wear-free operation with gearing of the highest quality and a correspondingly long service life. The use of the gear units enables the deployment of fast-running generators with a small air gap. Despite the unavoidable gear efficiencies, the efficiency of the power station is improved by approximately 1% through the use of gear units.

Characteristics:

• Compact, extremely lightweight design
• Integrated high-speed couplings and coupling guards.
• Integrated axial bearing for absorbing turbine forces.
• Compensation of external thermal axial forces
• Co-axial shaft arrangement (no center distance)
• Low noise emissions due to double-walled housing
• Highly efficient, even during partial-load operation
• Optionally available in a flange version (no base)
• Operation between idling and full load possible
• Wear-free slide bearings
• Design with through bore for blade adjustment optionally available
