- the main focus is on a free passage through the worm wheel for the passage of cables, lines, etc., which requires a similar or larger recess in a chassis carrying the assembly.
- the underside of the worm wheel is in a common plane with the housing bottom, so that od in a load-bearing chassis.
- the worm wheel on the relevant mounting surface of the chassis od.
- Grinds along. This can occur, in particular, when the carrying capacity of the ball bearing supporting the worm wheel is reduced.
- This rotary actuator can be used to rotate or adjust any parts of a machine or equipment with respect to another chassis, foundation or other machine or equipment part.
- the mutually rotatable or adjustable parts are arranged around a common main axis.
- connection surface of the housing relative to the corresponding end face of the worm wheel in the relevant direction is preferably raised and penetrated by a plurality of annularly distributed arranged holes, which are distributed at equidistant intervals over the entire circumference of the housing and each equal distances to the Have major axis.
- the mounting surface in question in the chassis od. Like. Have no asymmetric U-shape, and the orientation of the screw can be varied, even after the holes in the mounting surface of the chassis od.
- roller-shaped rolling elements or sliding elements often have an increased bearing force in relation to balls, so that the worm wheel is guided free of play even under heavy stress and also with an increased running time and therefore can not slide along a mounting surface of the chassis the same has no feed-through.
- the invention may also be easily equipped with ball or ball-roller-shaped rolling elements.
- the bores of the housing prefferably be formed on a chassis, foundation or another machine or system part as blind-hole bores provided with internal threads. This is a screw only from one side to operate, because no lock nut is to be fixed. Such a method of attachment makes it easier, especially with comparatively large-volume gear arrangements, to assemble them considerably, because this can spare a person; only one person is required to insert and tighten a screw.

- These rolling elements should therefore have a support angle ⁇ of more than 0 °: ⁇ > 0 °. So they do not form pure radial bearings, but also have an axial load capacity component. As a result, the permissible axial tensile forces between the worm wheel and the housing are about the same size as the permissible axial compressive forces.
