The invention relates to a bevel gear transmission having a housing ( 1 ), whose walls ( 2 ) are provided with at least two passage holes ( 3, 3' ) for at least two bevel gears ( 4, 4' ) that engage with one another with their gearings inside the transmission housing ( 1 ). At lest one of said bevel gears has a shaft ( 5 ) rotationally mounted in a bearing ( 22, 23 ) of a bearing casing ( 6 ), said shaft projecting from the transmission housing ( 1 ) through the passage hole ( 3 ), wherein the bearing casing ( 6 ) is fixed to the transmission housing ( 1 ). According to the invention, axial displacement of the bevel gear ( 4 ) can be exactly and reproducibly carried out due to the fact that a fixing part ( 9 ) that is configured separately from the bearing housing ( 6 ) is fixed to the transmission housing ( 1 ) said fixing part having an inner thread ( 13 ) that can be screwed with the outer thread of the bearing casing ( 6 ), that the relative angular position between the fixing part ( 9 ) and the bearing housing ( 6 ) can be fixed and that the bearing housing ( 6 ), when assembled with a cylindrical attachment ( 8 ), tightly fits into the corresponding passage hole ( 3 ) of the transmission housing ( 1 ), that is configured in the form of a guide.
