Gear housing
First Claim
1. A gear housing with a gear unit with a housing base body (4), with a housing cover (3) secured to the housing base body (4) by means of a plurality of retaining clips (6) made of spring steel which are spaced apart in the circumferential direction, and with a ring seal (20) which is arranged between the housing base body (4) and housing cover (3) and which is pressed against a bearing region (24) of the housing base body (4), characterized in that the radial extension (y) of the bearing region (24) is smaller than the radial extension (x, x′
- ) of the ring seal (20), characterized in that the ring seal (20) is arranged in a receiving groove (21) of the housing cover (3), characterized in that the receiving groove (21) defines a first width at a base of the receiving groove (21) and a second width at an opening of the receiving groove (21) and proximate the bearing region (24), wherein the second width is greater than the first width such that the ring seal (20) is permitted to widen adjacent the bearing region (24).
