Abstract
A housing component includes a flange defining a center point and having an end face formed with microstructures in a first region and a second region to increase a local friction coefficient. The microstructures have each a blade shape with a cutting line, the cutting line in the first region being arranged concentrically about a first local center point, and the cutting line in the second region being arranged concentrically about a second local center point. The first and second local center points have different radial distances from the center point of the flange.

A housing component, comprising a flange defining, a center point and having an end face formed with microstructures in a first region and a second region to increase a local friction coefficient, said microstructures having each a blade shape with a cutting line, the cutting line in the first region being arranged concentrically about a first local center point, and the cutting line in the second region being arranged concentrically about a second local center point, the first and second local center points having different radial distances from the center point of the flange and a processing path extending in a circumferential processing direction and a radial processing direction connecting said first and second local center points, said processing path comprising further said microstructures.
A method for machining a housing component having a flange, said method comprising:
- positioning a milling cutter at a first local center point of an end face of the flange;
- machining the end face of the flange to create a microstructure;
- and
- moving the milling cutter along a processing path in a circumferential processing direction and in a radial processing direction from the first local center point to a second local center point while machining the end face;
- and
- generating further microstructures along the processing path.

A wind power installation, comprising:
- a nacelle;
- a planetary gear set comprising a ring gear, a planet gear rotatably arranged in the ring gear, and a housing including a housing component configured to accommodate the ring gear;
- said housing component comprising a flange defining a center point and having an end face formed with microstructures in a first region and a second region to increase a local friction coefficient, said microstructures having each a blade shape with a cutting line, the cutting line in the first region being arranged concentrically about a first local center point, and the cutting line in the second region being arranged concentrically about a second local center point, the first and second local center points having different radial distances from the center point of the flange and a processing path extending in a circumferential processing direction and a radial processing direction connecting said first and second local center points, said processing path comprising further said microstructures;
- a generator;
- and
- a rotor connected to the nacelle and coupled in a torque transferring manner to the planetary gear set to drive a generator.
