Title:
DUAL-HELICAL-GEAR SPEED REDUCTION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/173392
Kind Code:
A1
Abstract:
A dual-helical-gear speed reduction structure, comprising an input shaft, a high-speed shaft, a high-speed-level helical gear, a low-speed-level helical gear, a low-speed shaft, and an output shaft. The input shaft and the high-speed shaft are coaxially connected by means of a high-speed-level shaft coupling; a high-speed-level buffer pad is arranged between the high-speed shaft and the high-speed-level shaft coupling in an axial direction, and the input shaft is equipped with a high-speed-level brake drum; the output shaft and the low-speed shaft are coaxially connected by means of a low-speed-level shaft coupling, a low-speed-level buffer pad is arranged between the low-speed shaft and the low-speed-level shaft coupling in the axial direction, and the output shaft is equipped with a low-speed-level brake drum; the high-speed-level helical gear is fixedly installed on the high-speed shaft, the low-speed-level helical gear is fixedly installed on the low-speed shaft, the high-speed-level helical gear is engaged with the low-speed-level helical gear, and the high-speed-level helical gear and the low-speed-level helical gear have the same normal modulus, normal pressure angle, transverse modulus and transverse pressure angle. According to the present invention, the gear reduction error can be reduced, the gear reduction reliability is improved, and the engagement transmission performance is better than traditional spur gear engagement transmission.
