Curler Gears were first present in high reduction differential models and 1000's of models were offered. Today many gearing companies creates the third generation of planetary and cyclonical curler gears used in many of apparatus heads, speed reducers and speed increasers delivering maximum torque-minimum space. The expansion process, driven by demands from changing industries, features to several purposes of this new technology. Good examples include: auger drives, industrial mixers, welding robots, portable honing machines, ergonomic valve actuators, drives with counter-rotating double results and speed increasers--a long list. Generation x curler gear matrix is different from under 1 " across close...
