Abstract
A method to form a gear for motor vehicles includes one or more of the following: placing a blank between a first tool member and a second tool member, each of the first tool member and the second tool member having a set of teeth; and moving the first tool member and the second tool member towards the blank while rotating the first tool member and the second tool member to form a gear with a set of teeth from the blank. Each tooth of the set of teeth has a topography that varies tooth-to-tooth.

A method to form a gear for motor vehicles, the method comprising:
- placing a blank between a first tool member and a second tool member, each of the first tool member and the second tool member having a set of teeth;
- and
- moving the first tool member and the second tool member towards the blank while rotating the first tool member and the second tool member to form a gear with a set of teeth from the blank,
- wherein each tooth of the set of teeth has a topography that varies tooth-to-tooth.
A method to form a gear for motor vehicles, the method comprising:
- placing a blank between a first tool member and a second tool member, the blank being made of powered metal, each of the first tool member and the second tool member having a set of teeth;
- and
- moving the first tool member and the second tool member towards the blank while rotating the first tool member and the second tool member to form a gear with a set of teeth from the blank by cold rolling,
- wherein the set of teeth of the gear has a scattered tooth-to-tooth topography.
A gear for a motor vehicle, the gear comprising:
- a set of teeth formed from a blank by cold rolling,
- the set of teeth having a random tooth-to-tooth topography.
