Abstract

A service brake for a wind turbine yaw motor brake is provided, the service brake including a brake housing comprising a brake housing cavity extending axially, in direction of a central axis, through the length of the brake housing. A brake disc is included within the brake housing, being rotatable about the central axis in an airgap between friction plates. A lever is connected to the brake housing, and, when engaged, is configured to close at least part of the airgap and bring the friction plates in frictional contact with the brake disc. A removable centerpiece is insertable within the brake housing cavity, the centerpiece includes a brake disc interface configured to engage with the brake disc and a shaft interface configured to engage with a shaft to be braked. The centerpiece is configurable to transfer braking torque from the brake disc to the shaft to be braked.

Dependent claims

A service brake for a wind turbine yaw motor brake, the service brake comprising:

a brake housing mounted vertically on the wind turbine yaw motor brake, the brake housing comprising a brake housing cavity extending axially, in a direction of a central vertical axis, through a length of the brake housing;
a brake disc within the brake housing, the brake disc being rotatable about the central vertical axis in an airgap;
at least one friction plate arranged within the brake housing for providing a frictional contact with the brake disc;
a manipulation device connected to the brake housing, the manipulation device, when engaged, is configured to bring the at least one friction plate in frictional contact with the brake disc;
and
a centerpiece comprising a brake disc interface configured to engage with the brake disc, and a shaft interface configured to engage with a shaft to be braked, configurable to transfer braking torque from the brake disc to the shaft to be braked, wherein the centerpiece is removable and is configured to be insertable within the brake housing cavity and rotatable about the central vertical axis.
