Abstract
A pulse generating wheel, combined with a radial shaft sealing ring, for a machine element that can rotate about an axis. The pulse generating wheel has a cylindrical sleeve that can be slid onto the machine element. The radial shaft sealing ring is provided with a sealing lip, made of polymer material, that is delimited on the side facing the atmosphere by a conical surface. In a first axial position of the cylindrical sleeve, the conical surface is contacted by the cylindrical sleeve and can be expanded in the radial direction. The cylindrical sleeve can be displaced out of the first axial position into a second axial position in which the sealing lip moves into direct contact with the machine element, and the cylindrical sleeve is at an axial distance from the conical surface.
