STEP-UP GEAR AT CYCLOID ENGAGEMENT Russian patent published in 2003 - IPC

FIELD: mechanical engineering; step-up gears at cycloid engagement. SUBSTANCE: step-up gear has body where first sun gear wheel is secured immovably and driven shaft which may be thrown into engagement with sun gear wheel; eccentric journal of said shaft carries drive shaft; step-up gear is also provided with drive shaft and second sun gear wheel. First sun gear wheel is made in form of disk with cogs located symmetrically and evenly on its face. Satellite is made in form of gear wheel with epicycloidal teeth thrown into cycloid engagement with cogs of sun gear wheel. Second sun gear wheel is made in form of disk with cogs located symmetrically and evenly on its face similarly to first sun gear wheel at the same radial distance from axis of rotation of drive shaft; number of cogs of second sun gear wheel is one less cog. Cogs of respective sun gear wheels face each other for flexible self-setting; they are just outer races of anti-friction bearings whose inner races are rigidly secured on free ends of pins. Gear wheel of satellite is made in form of two gear wheels which are linked rigidly and are provided with epicycloidal teeth; number of teeth is equal to number of cogs of second sun gear wheel. EFFECT: enhanced efficiency. 5 dwg
