1 NGC StanGear Introduction
What is NGC StanGear?
NGC StanGear is a serialized product platform for wind main gearbox and pitch & yaw drives from which the wind
turbine manufacturers can choose the appropriate existing products from the catalog to match their needs. NGC
StanGear includes StanGear standard products and its variants. StanGear series products are completely compliance
with the contents of 6th and 7th chapter. StanGear variants products define the gearbox's ratio , install dimensions or
output pinion's teeth number are not compliance with the content of 7th chapter.
How is NGC StanGear generated?
Up until now, the wind gearboxes are mainly designed according to the turbine manufacturers's specifications. It
leads to a big diversity of the gearboxes in the wind farms, long new product development period, rigid cost structure
due to limited scale and reliability risk due to the new design.
Based on its big database and reliability study over 50,000 main gearboxes and over 300,000 pitch and yaw drives
delivered worldwide, as well as the diversified field applications, NGC has developed the NGC StanGear platform by
modularization and standardization of the layout structure, components and materials.

What are the customer's value of NGC StanGear?
• Lower cost of new product development
• Shorter time for new product to market
• Higher reliability
• Larger scale effect
• Optimized service
How to use the NGC StanGear by turbine manufacturers?
According to NGC StanGear catalog and the turbine specifications, the turbine designers choose either an exactly
same gearbox item or the closest one for the minimum modifications. The turbine designers should be ready to adjust
the turbine design to a limited extend so as to realize the maximum benefit for the whole turbine drive train.

• Gear accuracy refers to the cylindrical gear accuracy in accordance with ISO 1328-1995
• Gear hardness is determined by the load capacity of spur and bevel gears in accordance with ISO 6336-2006
• The quality of materials and heat treatment is determined by the load capacity of spur and bevel gears in
accordance with ISO 6336-5:2003,Part 5: Hardness and Quality of Materials
2.2 Features
• Brand-new NGC StanGearTM platform for Yaw and Pitch Gearboxes
• Modular design, less spare part variants.
• High density, low weight
• High reliability
• Advanced design tools including 2D, 3D drawings tools
• Optimized sealing design
• Advanced design software
• Short lead time thanks to modular and standard design
• Customized interfaces according to actural requirements
2.3 Important Notes
• The products and drawings shown here are simply examples with no binding force.
• Please refer to operation manual for further information about lubrication. Viscosity and types of lubricants should
meet the requirements described in operation manual or nameplate.
• Rotating parts should be protected from touch. Please observe related local laws and regulations about safety and
security.
• You may adjust lubricant amount, sealing, surface protection and other gearboxes performance according to
different applications.
• Please contact NGC, in the case user needs to do design according to IEC 61400.
• SYW、SPT series planegary gearbox are ready-to-install products and equipped with oil filling. The surfaces of
mounted flanges, shaft ends and attachment faces are protected with Tectyl anti-rust oil.
• SYW includes a compact planetary stages, configure with output pinion and electricalal motor. The planetary gearbox
include four planetary stages (if necessary, five planetary stages or bevel gear stages are OK), Which provides high
transmission ratio for high sensitive rotational movement The steadily increasing size of the nacelles calls for enen
higher torque rates. This can be achieved by arranging a certain number of drives spaced around the yaw bearing.
Presently, up to 16 gearboxes may be employed for the yaw control system.

• The efficiency of a wind turbine is main dependent on an optimal blade position to suit the respective wind force.
SPT series gearbox are used for adjusting the blades. This kind of gearbox include three planetary stages(if
necessary, two planet gear stages plus bevel gear stage is also ok) and an output pinion
• Operate and maintain the gearbox please according to the instruction
