Abstract
A worm gear for a worm gear system of a motor vehicle steering device may include a hub, a support element, and a gear rim. The gear rim may have a multiplicity of teeth that extend radially outward from a central encircling annular web. The support element may be a support ring that by means of an injection-molding method is injected between the gear rim and the hub. The support element may connect in a form-fitting manner the hub and the gear rim. The gear rim may include reinforcement ribs that, on both end sides, from the teeth extend radially in a direction of a worm gear longitudinal axis.
