Abstract
From the background information supplied by the inventors, news correspondents o btained the followingquote: “Typical examples of right-angle speed reducers inc lude gear mechanisms such as bevel gears, skewbevel gears, and worms and worm g ears. Such speed reducers also include drives that utilize a singlemechanism to perform reduction, and drives that employ a combination of typical coaxial swin g-typespeed reducer mechanisms. These speed reducers are used in numerous field s, such as robot joints.”
