Patent ID: 11841072

Abstract:
A transverse cycloid-pin gear pair includes a cycloidal gear with a cycloidal tooth flank and a pin gear with a pin tooth flank, the pin gear meshing with the cycloidal gear in a nutation transmission manner. Angles between reference surfaces of the pin gear and the cycloidal gear and corresponding axes are between 88° and 91°, and a sum of the two angles is less than 180°. Portions of the pin tooth flank and the cycloidal tooth flank are pin gear working flank and cycloidal gear working flank, respectively. A pressure angle between the pin gear working flank and the cycloidal gear working flank when meshing satisfies 45°−β−5°≤α≤45°−β+5°, where α is the pressure angle, β is a friction angle. A nutation deceleration device comprises a shell, a transverse cycloidal-pin gear pair, an input mechanism, an output mechanism, and a torque transfer component.
