Mechanical compact gear with cog wheels - with different numbers of teeth, has drive wheel, planetary arm and friction ring

摘要

The mechanical compact gear has cog wheels (96,7,9) with different numbers of teeth, and two or more rotary cog wheels making 4 and 12 relative movemens. The relative movement of one cog wheel (7) in relation to the fixed cog wheel (9) operates contrarily to the relative movement of the cog wheel (6) to cog wheel (7) and is continuously adjustable in amount. The drive wheel (1) has a planetary arm (2) as bearing for the friction ring (19) which has rounded cavities (18) on the back, and several recessed holes (16) containing balls (17) securely. ADVANTAGE - The gear has few constituent parts and is continuously adjustable and reversible.
