Problems solved by technology

However, it is conceivable here that due to the meshing of the teeth into the gear, especially in the spur toothing, an increased noise is generated

Embodiment Construction

[0034] exist figure 1 A schematic diagram of the arrangement of an embodiment of an assembly 10 according to the present invention is shown in FIG. 1 , which includes a first gear 11 and a second gear 12 , as an example of a helical gear. Here, both the first gear wheel 11 and the second gear wheel 12 have teeth 14 . The teeth 14 each have a tooth flank 13 here. At least one tooth flank 13 of a tooth 14 of the first gearwheel 11 can mesh with a tooth flank 13 of a tooth 14 of the second gearwheel 12 . According to the invention, when the tooth flanks 13 of the teeth 14 of the first gearwheel 11 mesh into the tooth flanks 13 of the teeth 14 of the second gearwheel 12, there is formed—not at figure 1 Shown in - a contact line or a contact area forming an acute or obtuse angle with the corrugation axis of the tooth flank 13 of the tooth 14 of the first gear 11 and / or the second gear 12 . In this case, the contact line or the contact zone is formed based on the configuration of...

Abstract

The invention relates to an assembly (10) for acoustically influencing toothed wheels (11, 12), comprising at least one first toothed wheel (11) with teeth (14) and a second toothed wheel (12) with teeth (14), the teeth (14) comprising flanks (13), at least one flank (13) of a tooth (14) of the first toothed wheel (11) being engageable with a flank (13) of a tooth (14) of the second toothed wheel(12), and at least one flank (13) of a tooth (14) of the first toothed wheel (11) forming a contact zone, or ideally a contact line, with an engaging flank (13) of a tooth (14) of a second toothed wheel (12), the contact zone or the contact line being located at an angle [alpha]Aq, of particularly between 5 degrees and 85 degrees or 95 degrees and 175 degrees, to an axis of a waviness, a microangular distribution and / or a microangular periodicity of the engaging flank (13) of the tooth (14) of the second toothed wheel (12). The invention further relates to a method for acoustically influencingtoothed wheels (11, 12), comprising an assembly (10) comprising at least one first toothed wheel (11) with teeth (14) and a second toothed wheel with teeth (12), the teeth (14) comprising flanks (13), and at least one flank (13) of a tooth (14) of the first toothed wheel (11) being engageable with a flank (13) of a tooth (14) of the second toothed wheel (12). The invention further relates to a vehicle comprising such an assembly (10) for acoustically influencing toothed wheels (11, 12).

Description

technical field [0001] The present invention relates to an assembly and method for influencing the sound of gears. Background technique [0002] When driving conventional vehicles, particularly in the balancer shaft, a gear connection is used which is often designed as a spur toothing. In the case of two gears in a gear connection meshing with one another, a contact line or contact zone is formed which runs parallel to the axis of rotation of the gears. The teeth of the gear wheel have tooth flanks, wherein the tooth flanks have corrugations which are ideally parallel to the contact line or contact region and to each other. As a result, the corrugations can easily engage one another on the mating tooth flanks, however, this results in a noise level. Furthermore, methods are known for analyzing the corrugation of a tooth. [0003] From DE 10 2014 109 914 A1 a device with gear and spur gear stages and a method for producing the gear are known. Therein, a contact line or co...
