Embodiment Construction

[0074] Figure 1 to Figure 3 A bearing with a lubricant collection system is exemplarily shown.

[0075] figure 1A cross-sectional view of the components of the bearing in a plane parallel to the axis of rotation of the bearing is shown. The bearing comprises a first bearing part 11 with an inner ring and a second bearing part 21 with an outer ring. A first contact surface 12 and a second contact surface 22 can be seen, which are arranged opposite to each other and at a relatively small distance from each other. The portion or region between the contact surfaces 12 , 22 is referred to as the contact portion 31 . The distance between the first bearing edge 14 and the second bearing edge 24 determines the bearing play 33 . Lubricant 37 leaking from the contact portion 31 can leak via the bearing gap 33 , ie along the bearing edges 14 , 24 . The first contact surface 12 forms a first angle 16 with the first front surface 13 ; the second contact surface 22 forms a second angl...

Abstract

A bearing, which is suitable for a wind turbine, with a lubricant collection system is provided. The bearing comprises a first bearing component with a first contact face and a first front face. It furthermore comprises a second bearing component with a second contact face and a second front face. The first front face is coupled with the first contact face; the second front face is coupled with the second contact face. The first bearing component and the second bearing component are movable relative to each other. The first contact face and the second contact face are prepared and arranged in a way to accommodate a lubricant. Furthermore, the bearing comprises a scraper, which is attached to the first front face and is in contact with the second front face. Finally, the invention also relates to a method of collecting a lubricant leaking out of a bearing, wherein the bearing is suitable for a wind turbine and comprises a first step of scraping off the lubricant escaping from in-between the first contact face and the second contact face, and a second step of guiding the scraped-off lubricant to a lubricant collection device by means of gravitational force.

Description

technical field [0001] The present invention generally relates to an improved bearing. More specifically, the present invention relates to a bearing having a lubricant collection system. Furthermore, the invention relates to a method of collecting lubricant leaking from a bearing, for example a bearing of a wind turbine. Background technique [0002] Bearings generally comprise at least two parts that move relative to each other. Typically, friction is created between the moving parts of the bearing. Lubricants are often added between moving parts in order to reduce friction and thus increase efficiency and extend bearing life. [0003] Bearings are used in all kinds of machines, equipment and installations. As an example, bearings are used in wind turbines. A wind turbine generally includes a tower, a nacelle and a rotor. The rotor may include a rotor shaft and a rotor hub, where the rotor blades are attached to the rotor hub. The rotor shaft, which rotates about the...
