Inner gear sleeve and crowning processed outer gear are interlocked. These gears were designed as involute teeth with special shape, and they can softly transfer power at the same rotations even if a slight slope is formed between sleeve and hub.

 Features

→ It has small size and light weight compared to horsepower and can be used for high speed rotation 
→ Teeth of hub is handled by crown to absorb eccentricity, deflection and error in shaft movement, it delivers strong power while protecting the machine part 
→ Large and special types can be ordered depending on the place of application 
→ It has large allowable error about flow of shaft 
→ It has long lifetime and small loss of power transfer.
