Abstract
A toothing arrangement () includes at least one first helical-cut spur gear () and a second helical-cut spur gear (), which form a common meshing toothing, and as least one thrust collar () with two races () for axial load compensation on both sides in the region of the meshing toothing. The annular thrust collar () includes an internal gearing (), which, in the mounted state, is supported in a circumferential groove () interrupting the tooth system () of the first spur gear (). At least one rotation prevention means is associated with the thrust collar (). The rotation prevention means is movable from a radially inner region to a radially outer region of the first spur gear () into an interlock position. A transmission may include the toothing arrangement.
