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 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 ring may connect in a form-fitting manner the hub and the gear rim. The gear rim and the support element may configure a multiplicity of teeth. The support element may have support webs that penetrate the gear rim such that radially outward pointing end sides of the support webs are exposed.
