Abstract
A worm gear for an electromechanical power steering system of a motor vehicle, includes a worm shaft that meshes with a worm wheel. The worm wheel and the worm shaft are arranged together in a gear housing. An eccentric lever and a bimetallic spring that is operatively connected to the eccentric lever are configured to compensate for a temperature-related play in the engagement between the worm wheel and the worm shaft.
