Problems solved by technology

While the SPIROID gear accomplishes this, at times, even smaller size limitations may apply.
Such gear assemblies, however, have been found to have deficiencies.
A skew-axis gear arrangement can often preclude ready incorporation of the gear assembly into an actuator design due to added complexities of bearing arrangements and support, atypical housing and mounting features that increase machining, fabrication, and assembly complexities; and general reluctance by potential end-users to adopt the technology due to added complexities with incorporating atypical mounting and motor connection features into their systems.

Abstract

A gear assembly includes an actuation gear and plural separate pinion bodies. The actuation gear has first gear teeth on one or more surfaces of the gear and is configured to rotate around an actuation axis of rotation. The pinion bodies have second gear teeth configured to mesh with the first gear teeth of the actuation gear in plural separate mesh zones of the actuation gear. Each of the plural separate pinion bodies are configured to be rotated about respective pinion axes of rotation to cause rotation of the actuation gear around the actuation axis of rotation.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to, and is a continuation of, U.S. application Ser. No. 14 / 486,677, which was filed on 15 Sep. 2014.BACKGROUND[0002]Gears are used to, among other things, transmit power from one device to another and / or change a direction of an applied force. Many types of gears are known, such as straight gears, angle gears, bevel gears, worm gears, combinations of these gears, and others. Also known are SPIROID brand gears that use a curved gear tooth. Such a configuration of gears permits larger loads to be transferred due to the increased surface area of gear tooth relative to a straight gear formed on a similar blank.[0003]Certain applications may require gears that withstand high loads (e.g., forces). Generally, the ability to withstand such forces is accomplished by using larger gears to increase the area on the gear teeth over which the forces are exerted. The ability to withstand forces is balanced against size r...
