Abstract
The present device includes gears with bending compliance in the outer portion of the gear teeth to reduce gear noise. The present device reduces the variation in gear stiffness by introducing bending compliance in the outer portion of the gear tooth, by way of a cutout or relief area in the distal end of the tooth.
Claims14
A gear comprising:
- a gear body, wherein a cross-section of the gear body is a disk having an outer perimeter;
- and
- a plurality of gear teeth extending from the outer perimeter of the gear body at regular intervals, wherein each gear tooth includes
- a distal end and a proximal end,
- two side edge connecting the distal end to the proximal end,
- a cutout in the distal end of the gear tooth, wherein the cutout forms at least two forklike protrusions in the distal end of the gear tooth.

A gear set comprising:
- a pair of mating gears, wherein at least one gear includes a gear body, wherein a cross-section of the gear body is a disk having an outer perimeter, and
- a plurality of gear teeth extending from the outer perimeter of the gear body at regular intervals, wherein each gear tooth includes
- a distal end and a proximal end,
- two side edges connecting the distal end to the proximal end,
- a cutout in the distal end of the gear tooth, wherein the cutout forms two forklike protrusions in the distal end of the gear tooth.
