Disclosed is a wind turbine, which comprises a rotatable structure being coupled to a hub of the wind turbine and to a generator rotor comprising a brake disc, a stationary structure being coupled to a generator stator and comprising a stator frame and a safety bearing element. The rotatable structure is rotatably coupled to the stationary structure, wherein the stator frame comprises a brake mounting section to which a calliper brake is mountable such that the brake disc is breakable by the mounted calliper brake. The safety bearing element is mounted to the brake mounting section such that the brake disc is in slidable contact with the safety bearing element if a distance between the brake mounting section and the brake disc is reduced below a predetermined reference value.

A brake system, especially for a generator, including a rotor assembly, a stator assembly and a rotation axis is disclosed. The rotor assembly includes an outer portion which is located radially outward of the stator assembly. The outer portion includes a brake disc, and the stator assembly comprises at least one frictional member operatively configured for frictionally engaging at least a portion of the brake disc.

Brake system, generator and wind turbine

A brake system for a wind turbine with integrated rotor lock, generator and wind turbine are disclosed. The brake system includes a rotor lock system which is integrated in the brake system. One embodiment includes an actuator such as a hydraulic cylinder. Another embodiment includes a rotor assembly with a brake disc.

A lubrication system is provided for a bearing with a stationary inner ring and a rotating outer ring. The lubrication system includes a distribution ring attached to the outer ring for distributing a lubricant in the bearing. The distribution ring includes transport openings directed towards the bearing for transportation of the lubricant from a lower position of the outer ring to an upper position of the outer ring.
