摘要

The ring (60) has a guidance edge (80) of a moving element (74) i.e. roller, where the guidance edge includes an interior surface (81), and an external surface (85) that is arranged opposed to the interior surface. The interior surface of the guidance edge forms a guidance shoulder for the moving element. The guidance edge is arranged with a crossing hole that crosses the interior surface and the external surface, where the crossing hole is intended for defining an opening for drainage (82) of a lubricant i.e. oil. Independent claims are also included for the following: (1) a turboshaft engine assembly (2) a turboshaft engine.
