Abstract
A gear for use in a transmission system. The gear comprises an outer annular element having gear teeth on a radially outer surface thereof and an inner support element arranged coaxially with the outer annular element. The gear further comprises first and second opposing side walls, each side wall extending from the outer annular element to the inner support element to form an annular space. At least one of the first and second side walls extends from the outer annular element at an angle greater than 0 degrees with respect to a direction perpendicular to the rotational axis of the gear.

A gear for use in a transmission system, the gear comprising:
- an outer annular element having gear teeth arranged helically on a radially outer surface thereof;
- an inner support element arranged coaxially with the outer annular element;
- and
- first and second opposing side walls, each side wall extending from the outer annular element to the inner support element to form an annular space,
- wherein both of the first and second side walls extend from the outer annular element at an angle greater than 0 degrees with respect to a direction perpendicular to the rotational axis of the gear, and
- wherein each of the first and second side walls are constantly inclined between the outer annular element and the inner support element, and each of the first and second side walls are rigidly connected to or integral with each of the outer annular element and the inner support element such that the first and second side walls are configured to resist gear loading forces in the axial direction.
