Document Type and Number:
WIPO Patent Application WO/2020/034816
Kind Code:
A1
Abstract:
Disclosed are an end face toothed cycloidal-pin gear pair and a nutation reduction device. The end face toothed cycloid-pin gear pair comprises a cycloidal gear with a cycloidal toothed face and a pin gear with a pin gear toothed face, wherein the pin gear engages with the cycloidal gear in a nutation transmission manner; the included angles between the indexing faces of the pin gear and the cycloidal gear and corresponding axes thereof each are between 88° and 91°, and the sum of the two included angles is less than 180°; and the parts, engaging with each other, of the pin gear toothed face and cycloidal toothed face are a pin gear operating toothed face and a cycloidal gear operating toothed face, respectively, and the pressure angle between the pin gear operating toothed face and cycloidal gear operating toothed face when engaging with each other meets the relationship: 45°-β-5° ≤ α ≤ 45°-β+5°, wherein α is the pressure angle, and β is the friction angle between the pin gear operating toothed face and the cycloidal gear operating toothed face.
