SPIROID GEAR PAIRS Spiroid gear pair is operate on nonintersecting, nonparallel axes. It involves a tapered pinion that somewhat resembles a worm. The spiroid gear is a face gear with teeth curved in a lengthwise direction; the tooth is like a helix angle-but not a true helical spiral. Figure shows the schematic relation on the spiroid gear pairs to cylindrical worm gears, hypoid gears and bevel gears. Generally, the shaft angle ∑=90°. The corresponding installation position of spiroid pinion and spiroid gear is: the left hand of spiroid pinion applies down offset and the left hand of...

4、High transmission efficiency, smooth operation and low noise level Spiroid gear pairs are not only has better lubrication, but the friction between the tooth surfaces is helpful for the rotation of the spiroid gear. As shown in the Figure, both friction force Fu and normal force Fn make the spiroid gear rotation in the same direction. So when the spiroid pinion and spiroid gear has proper rotation direction and transmission position, it can achieve high transmission efficiency. left hand worm gear w2 Aerospace National defense Medical instruments Robot joints Indexing device of tooling...
