Worm gear

Abstract

Worm gear with gear housing (10) with a surface, which consists of sections and cultivation areas (14, 52), that each section borders at least two cultivation areas (14, 52) and, each section, at every point of this section, is continuously convexly curved along at least one of its surface curves, wherein this surface curve is the intersection of an imaginary normal plane belonging to a point of this section with this section, wherein the mounting surfaces (14, 52) are uncurved and, in the installed state of the gearbox housing (10), are covered by appropriate cover elements and / or attached devices, wherein the mounting surfaces (14, 52), each having a bore, are perpendicular or parallel to each other and, in the installed state of the gearbox housing (10), the mounting surfaces (14, 52) are covered by corresponding surfaces of attached devices and / or by a suitable cover element, wherein the surface, cast from stainless steel and subsequently ground and / or electropolished, is coated with a non-corrosive and / or non-stick polymer.
