<p>The invention is directed to a worm gear mechanism comprising a worm shaft with a worm thread formed or worked, in particular cut, directly into the shaft main body, and also comprising a worm wheel that meshes with said worm thread, which worm wheel is of annular form and is integrated with an annular connection element of an open-center large-diameter rolling bearing, the two annular, mutually concentric connection elements of which are supported against one another in rotatable fashion and serve for connection to two machine or installation parts that are rotatable relative to one another, wherein the toothed worm wheel connection element is formed from an annular main body with a toothing formed or worked directly therein, having at least one connection surface for abutment against a planar contact surface of the respective machine or installation part, and having multiple fastening bores arranged so as to be distributed in a ring around the clear opening, the longitudinal axes of which bores extend perpendicularly through the respective connection surface; and wherein the non-toothed connection element is formed from an annular main body with at least one planar connection surface for abutment against a planar contact surface of the respective machine or installation part, and having multiple fastening bores arranged distributed in a ring around the clear opening, the longitudinal axes of which bores extend perpendicularly through the respective connection surface; wherein furthermore, in the region of the worm, sensors are provided which permanently detect the (rotational) position of the worm; and to a method for the operation of a worm gear mechanism of said type.</p> |
