CROWN GEAR DECELERATION MECHANISM

摘要

The present invention addresses the problem of further increasing the strength, rigidity and durability of a crown gear deceleration mechanism. To solve the problem, this crown gear deceleration mechanism is provided with a stator obtained from a crown gear, a rotor obtained from another crown gear that is positioned at a slant with respect to the stator crown gear, and an output shaft connected to the rotor. The stator has a stator teeth row in which (NS) stator teeth are disposed in a circle. The rotor has a rotor teeth row in which (N) rotor teeth are disposed in a circle. The difference between (NS) and (N) is 1. The rotor performs a precessing movement while meshing multiple stator teeth with multiple rotor teeth at both a left position and a right position on either end of a central tilt line of the rotor.
