ECCENTRIC PLANETARY GEAR OF INTERNAL ENGAGEMENT

摘要

FIELD: transportation. ^ SUBSTANCE: eccentric planetary gear of internal engagement is intended to transform rotation speed with transmission ratio in the range of 5-100 for one step. There is central wheel (6) of internal engagement installed with teeth in the form of pin teeth (16) and planetary block (14) with teeth of cycloidal shape engaged with pin teeth. Rotation of planetary block (14) is transmitted to outlet shaft with the help of central (4) with fingers (5), which interact with open cuts in the form of circular arc on periphery of planetary block. Planetary block is arranged with single crown of complex shape, which has cycloidal tooth profile on one side, and on the other side tooth has a profile made of circular arcs. Number of cycloidal teeth is equal or multiple to number of teeth made of circular arcs. Profiles are outlined with curves that in case of combination in single plane lie one inside another without crossings. ^ EFFECT: increased strength and simplified technology of planetary block manufacturing. ^ 3 cl, 9 dwg
