3 1NGC StanGear Introduction NGC StanGearI ntroduction 1 What is NGC StanGear? Wind turbine market situation 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 series products classed into StanGear series and semistangear series. StanGear series products are completely compliance with the contents of 6th and 7th chapter. SemiStanGear series 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 by 50,000 main gearboxes and over 00,000 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?

The turbine designers should be Main Gearbox 0 < Power/MW ready to adjust the turbine design to a limited extend so as to realize the maximum benefit for the whole turbine drive train. Where do I get the detailed information of NGC StanGear? Please approach NGC engineers.

High density, low weight Oil level gauge= Oil Oil level glass Oil drainage= Oil Oil drainage High reliability Advanced design tools including 2D, D drawings tools Optimized sealing design Oil Advanced design software Breather= Oil filler= Short lead time thanks to modular and standard design Customized interfaces according to customers'requirements Breather Oil filler 2 2. 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. Oil outlet= Oil Visual inspection Opening = Rotating parts should be protected from touch. Please observe related local laws and regulations about safety and security. Oil outlet Visual inspection opening 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 SYW SPT series planegary gearbox are readyto install products and equipped with oil filling. The surfaces of mounted flanges, shaft ends and attachment faces are protected with Tectyl antirust 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. Oil inlet= Oil Lifting= Oil inlet Lifting 2.5 Supply scope specification For Yaw drive, the electricalal motor will be also included in the scope of supply. For Pitch drive gearbox, ifthere are special request, the electric motor may be included in the scope of supply. 0 04
