1What is NGC StanGear?
NGC StanGear is a serialized product platform for wind turbine main gearboxes and pitch & yaw drives, developed to provide turbine
manufacturers with the ability to select an appropriate gearbox for their needs from an existing catalog of units. NGC StanGear includes
StanGear standard products and its variants. StanGear standard products refer to those products listed in the NGC platforms, i.e. the
products which have recommended ratios and fulfill the specification in Part 4 and Part 5.
StanGear variants refer to those products adjusted and modified slightly based on the standard products, i.e. based on the specification
in Part 4 and Part 5. (including the adjustment on ratio and interface sizes for torque arm, flange, output shaft, quill shaft and brake disc.)
Please contact NGC for more detailed information.
How was NGC StanGear developed?
Traditionally, wind gearboxes have been designed according to the specifications of wind turbine manufacturers; an approach that has led
to a large diversity of gearboxes within each wind farm, long product development cycles and rigid cost structures due to the limited scale
and reliability risks associated with new designs.
Using data collected from NGC's extensive global installed base of more than 50,000 main gearboxes and more than 300,000 pitch and
yaw drives, the NGC StanGear platform was developed to solve these issues – bringing modularization and standardization to the layout.

What benefits does NGC StanGear bring for the customer?
• Reduced cost of new product development
• Less time needed to bring new products to market
• Higher reliability
• Optimized service
How is NGC StanGear used by turbine manufacturers?
Using the NGC StanGear catalog, turbine designers can quickly select a gearbox that will meet their requirements exactly, or understand
which gearboxes will work with the minimum amount of required modifications. To realize the maximum benefits for the whole turbine
drive train, slight adjustments to the turbine design may be required.

4.1 Methods of Selection
Step 1: Determination original input situation
(1) Requirement of gear units
Input power P1=_____kW, Input torque T1_____kNm，
Input speed n1=_____rpm, Output speed n2=_____rpm；
Structure: _____ (1 planetary stage + 2 parallel stages, 2 planetary stages + 1 planetary stage, 2 planetary
stages);
Type of input shaft: _____ (shrink disc, flange)
Mounting of torque arm_____ (3-point mounting, 4-point mounting); Required ratio: i= n1/n2=_____.
Step 2: Selecting gear unit type acc.to Nominal input torque
Nominal input torque of main gearboxes for wind turbine is calculated per certain inner conditions. Input torque
of selected gearbox should meet following prerequisites:
For NGC StanGear main gearboxes, the max. rated torque is calculated per certain inner conditions. The rated
torque of selected gearbox should meet following prerequisites:
T1=（9.55×P1）/n1 ≤ Tn
T1 – Rated input torque, kNm Tn – Max. rated torque, kNm，see table 1, 2, 3
P1 – Rated input power, kW n1 – Input speed, rpm
Refer to table 1 – 3 and determine appropriate main gearboxes platform according to calculated input torque
and required structure type.
