Described is a lubricating device with at least one lubricating pinion for applying a lubricant, in particular grease, which is for example fed through a lubricant line by a lubricant pump from a reservoir, to at least one gearwheel or the like, wherein the lubricating pinion has an outer toothing into which at least one lubricant outlet opens out. The teeth of the outer toothing of the lubricating pinion have a shortened tooth flank profile in relation to an involute toothing, wherein the addendum and/or the width of the tooth flanks in the peripheral direction are reduced in a tooth flank section which is situated radially outside the reference circle.

1. A gear assembly comprising at least one gearwheel having an involute toothing, and a lubricating device with at least one lubricant transfer pinion for applying a lubricant onto the at least one gearwheel, wherein the lubricant transfer pinion has an external toothing in which at least one lubricant outlet is arranged, and wherein the at least one lubricant transfer pinion meshes with the at least one gearwheel, characterized by the fact that only the teeth of the external toothing of the at least one lubricant transfer pinion have a tooth flank profile that is shortened in comparison to an involute toothing profile, and wherein an addendum of the tooth flanks of the teeth are reduced in a tooth flank section that lies radially outside a reference circle. 2. The gear assembly according to claim 1, characterized by the fact that the addendum of the teeth of the external toothing of the at least one lubricant transfer pinion is reduced in comparison to said involute toothing profile by 25% to 90%. 3. The gear assembly according to claim 2, characterized by the fact that the addendum of the teeth of the external toothing of the at least one lubricant transfer pinion is reduced in comparison to said involute toothing profile by 50% to 80%. 4. The gear assembly according to one of claims 1-3, characterized by the fact that the teeth of the external toothing of the at least one lubricant transfer pinion have a rounded tip contour comprising three radii. 5. The gear assembly according claim 4, characterized by the fact that the teeth of the external toothing of the at least one lubricant transfer pinion have a rounded tip contour such that a width between the tooth flanks of the teeth in a circumferential direction is reduced in comparison to said involute toothing profile in the tooth flank section that lies radially outside the reference circle. 6. The gear assembly according to claim 1, characterized by the fact that the teeth of the external toothing of the at least one lubricant transfer pinion have a rounded tip contour such that a width between the tooth flanks of the teeth in a circumferential direction is reduced in comparison to an involute toothing in a tooth flank section that lies radially outside the reference circle. 7. The gear assembly according to claim 1, characterized by the fact that the at least one lubricant transfer pinion comprises several lubricant conduits that originate at a lubricant supply line arranged on a rotational axis of the at least one lubricant transfer pinion or in an area near the rotational axis and respectively lead into said at least one lubricant outlet in one of the teeth. 8. The gear assembly according to claim 1, characterized by the fact that at least two lubricant outlets are arranged in each tooth of the at least one lubricant transfer pinion. 9. The gear assembly according to claim 8, characterized by the fact that the at least two lubricant outlets are connected by a transverse groove or a channel that extends over almost an entire width of the tooth flanks in an axial direction with respect to the at least one lubricant transfer pinion. 10. The gear assembly according to claim 8, characterized by the fact that at least one lubricant outlet leads into each tooth flank of the at least one lubricant transfer pinion. 11. The lubricating device according to one of claims 1-3, characterized by lubricant outlets, including said at least one lubricant outlet, in an area of the pitch circle and/or in an area between the pitch circle and the root circle, lead into the tooth flanks of the at least one lubricant transfer pinion. 12. The gear assembly according to claim 1, characterized by the fact that the external toothing of the at least one lubricant transfer pinion comprises a rounded contour with a tip area having a larger radius that transitions laterally into smaller radii. 13. The gear assembly according to claim 1, characterized by the fact that a width between the tooth flanks of the teeth in the circumferential direction is reduced in the tooth flank section that lies radially outside the reference circle.
