1 Scope

This standard is applicable to closed speed-increasing gearboxes of horizontal shaft wind turbine power trains with rated power greater than 500 kW. this The standard applies to wind turbine gearboxes installed on land or at sea. This standard provides guidance for load analysis of gear and gearbox components designed in wind turbines. The gear parts to which this standard applies include. parallel shafts in the main drive chain and planetary gears, such as spur gears, helical gears or herringbone teeth. wheel. This standard does not apply to gear power take-off devices (PTO). This standard is based on the design of a gearbox using rolling bearings. The use of plain bearings allows reference to this standard, but this standard does not include slippage. Evaluation of the use of moving bearings. This standard also provides engineering guidance for shaft, shaft and hub interfaces, bearings and gearbox housing structures in a fully integrated design. Its poor operating conditions. In addition to type testing and product testing, this standard also includes lubrication of the transmission. Finally, this standard also applies to the operation of the gearbox. Maintenance provides guidance.
