Involute gear teeth for fluid metering device |
摘要 |
An oval gear set for use in a flow meter comprises first and second gears that are identical to each other and that are configured to engage at a fixed center-to-center distance such that the first and second gears mesh at all angular positions. Each gear of the oval gear set comprises a hub and a plurality of gear teeth. The hub comprises an oval body having a major axis and a minor axis extending through a center of the hub, and a root profile wall circumscribing the major and minor axes. The plurality of gear teeth extend from the root profile wall. Each of the gear teeth has a pair of contact surfaces with circular involute curve profiles. |
