Abstract

A greaser for a transmission includes a shaft (1) having an axial bore (3) and a plurality of axially spaced radial bores (6a, 6b, 6c). Each of at least one tube (8a, 8b) is inserted into a respective one of the axially spaced radial bores (6a, 6b) and extends radially inwardly into the axial bore (3) beyond a circumferential surface (4) of the axial bore (3) that is adjacent the respective one of the axially spaced radial bores (6a, 6b). Each of the at least one tube (8a, 8b) includes a slot (11a, 11b) at a tube end (10a, 10b) facing a central axis (2) of the shaft (1). The slot (11a, 11b) of each of the at least one tube (8a, 8b) extends along a central axis (9a, 9b) of the respective tube (8a, 8b) into an interior space of the axial bore (3).
