Yaw bearing

About this product

To connect and support towers and nacels. the wind rotor shaft is always blowing. Control to match direction

Yaw bearing is an important part of the yaw system of horizontal axis wind power generators. The yaw system is a direction control system that controls the axis so that it stays consistent with the direction of the wind. The yaw bearing is a key part which is a gear type that connects to the fixed tower and rotating nacelle, while supporting it. It requires much attection especially in the consistency and design against errors, while also requiring surface strengthening technologies for hight-frequency heat treatment, not to mention hight levels of gear processing technologies.

Alloy steel for mechanical structures, such as 42CrMo4 (SCM440) are commonly used for bearings. The pich and yaw bearing must withstand large amunts of both static and dynamic load and momentum, while the wind power generator is operating.In addition, the yaw bearing is in charge of the soft rotation for the operation of the nacelle and the pitch bearing is in charge of active control of the blade in all wearther conditions. Furthermore, it must have resistance against corrosion and damages during its given lifetime.

Bearing materials are mainly used for mechanical structural alloy steels such as 42CrMo4 (SCM440). Pitch and yaw bearings provide a huge static, dynamic load and moment during the operation of the wind generator. You have to endure it. And, under all weather conditions, the yaw bearing rotates smoothly in the operation of the nousel, Pitch. Bearing acts as the active control of the blade, and over a given lifetime, it acts as a corrosion and damage. You have to have resistance that you can withstand.
