Embodiment Construction

[0052] exist figure 1 In a) a first gear wheel 10 according to a first embodiment of the invention is shown, which is embodied as a worm 12 and is made entirely of plastic. The worm 12 has a first toothing section 14 in which a plurality of teeth 16 are located. The first gear tooth segment 14 has a first inclination angle β 1 .

[0053] exist figure 1 In b) the second gear wheel 18 according to the first embodiment of the invention is shown. The second gearwheel 18 is designed as a helical gearwheel 20 and is made entirely of metal. The helical gear 20 has a second toothing section 22 in which a plurality of teeth 16 are located. The second tooth segment 22 has a second inclination angle β 2 .

[0054] According to the definition, in the following, the first inclination angle β 1 should always be assigned to the plastic tooth section and the second inclination angle β 2 The assignment should always be made to a metal gear tooth segment, irrespective of whether the re...

Abstract

The present application relates to a gear pairing for a helical gear unit or a spur gear unit, comprising a first gear with a first toothing portion, and a second gear with a second toothing portion,wherein the first gear has a first axis and the second gear has a second axis, which enclose a shaft angle, which is between 0 and 90 degrees, the first toothing portion and the second toothing portion can be brought into meshing engagement and, when engaged, form an involute toothing, the materials of the first and second toothing portions are chosen so that, when engaged, a material pairing metal / plastic results, and the toothing portion made of plastic has a first helix angle and the toothing portion made of metal has a second helix angle. The formula is as shown in the description.

Description

technical field [0001] The invention relates to a gear pair for a helical or spur gear, a helical or spur gear having such a gear pair and the use of such a gear pair in a helical or spur gear application. Background technique [0002] Helical gear drives with a gear pair consisting of a helical gear and a worm are used in many applications, in particular because large transmission ratios can be realized with a small amount of space. Due to this characteristic, helical gear drives are widely used in auxiliary drives in the automotive sector for the adjustment of two vehicle components which can be adjusted relative to each other. Since self-braking can be achieved using the helical gear, once the position of the two vehicle parts relative to each other has been set, no additional measures are required to fix this position. [0003] It should be pointed out here that a helical gear drive has a great similarity to a worm gear, which consists of a worm and a worm wheel. In h...
