The invention relates to an arrangement for lubricating a gear wheel (1) of a gear transmission. The arrangement includes at least one duct (20, 21, 22) which is intended to deliver lubricant under pressure and has a discharge orifice located adjacent the gear wheel (1). According to the invention, the duct (20, 21, 22) discharges adjacent the gear wheel (1) in at least one circle-arcuate groove (24) in an element (14) which abuts the end surface (15) of the gear wheel (1). The groove (24) or each groove is open towards the gear wheel (1) and extends in the circumferential direction thereof and is located concentrically with the gear wheel (1) and hals an outer defining surface (25) whose radius is somewhat larger than the radius of the bottom surface (26) of the gear wheel (1). |
