Embodiment Construction

[0030] exist figure 1 A cross-sectional view of a helical gear 10 according to an embodiment of the present invention compared with a helical gear 10P based on a reference tooth profile is shown in . Here, the solid line indicates the helical gear 10 according to the present invention, and the broken line indicates the helical gear 10P, which has been mass-produced by the present applicant.

[0031] The helical gear 10 shown is entirely made of metal. The helical gear 10 has a first toothing section 12 in which a plurality of teeth 14 are located. The radial inner side of the first toothing section 12 has a root circle diameter d f2 The dedendum circle is delimited, while the radially outer side of the first toothing section 12 is defined by a dedendum circle diameter d a2 The addendum circle is defined by .

[0032] Furthermore, the teeth 14 of the helical gear 10 have a normal tooth thickness s n2 , the normal tooth thickness s n2 Indicates that the teeth 14 of the hel...

Abstract

A gear pair for a helical gear transmission (22), comprising a helical gear (10) with a first toothing segment (12), and a worm (16) with a second toothing segment (18), wherein the first toothing segment (12) and the second toothing segment (18) can be brought into intermeshing and form an involute toothing (26) when intermeshed, the materials of the first and the second toothing segments (12, 18) are chosen such that when intermeshed there results a plastic-metal material pairing, and the toothing segments (12, 18) made of plastic has a first normal tooth thickness (sn1) and the toothing segments (12, 18) made of metal has a second normal tooth thickness (sn2), wherein the ratio of the first normal tooth thickness (sn1) to the second normal tooth thickness is increased by 10 to 200% withrespect to a reference profile.

Description

technical field [0001] The invention relates to a gear pair for a helical gear, a helical gear with such a gear and the use of such a gear in a helical gear. Background technique [0002] Helical gear transmissions, which consist of a gear pair consisting of a helical gear and a worm, have a strong resemblance to worm gears and are used in many applications, not least because of the large transmission ratios that can be achieved in a small space . Due to this characteristic, helical gears are widely used in the automotive sector for adjusting two mutually adjustable vehicle components. Since the self-braking can be realized using the helical gear, no additional measures are required to determine the position of the two vehicle parts relative to each other. Examples of applications for helical gear drives in the automotive sector are seat length adjustment and power window adjustment. [0003] Here, the helical gear has a first toothing section and the worm has a second to...
