Gear for a gear pair, gear pairing, method for manufacturing a gear, drive train and vehicle
The invention relates to a gear (10) for a gear pair of a vehicle drive train, comprising: a first tooth (11) with a first tooth flank (12) and at least one second tooth (15) with a first tooth flank (17), wherein the first tooth flank (12) of the first tooth (11) has a first modified surface region (13) within a surface (14) of the first tooth flank (12), wherein the first modified surface region (13) and a surface (16) of the first tooth flank (17) of the second tooth (15) differ such that tonal noise generation during operation of the gear pair is reduced. The invention further relates to a gear pair with such a gear, a method for manufacturing such a gear, a drive train, and a vehicle.
