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, the present invention is provided with a stator obtained from a crown gear, a rotor obtained from another crown gear, and an output shaft connected to the rotor. The stator has a stator teeth row in which (N1S) stator teeth are disposed in a circle. The rotor has a first rotor teeth row in which (N1) teeth are disposed and a second rotor teeth row in which (N2) teeth are disposed. The output shaft has an output teeth row in which (N2S) teeth are disposed. The rotor performs a precessing movement while meshing the first rotor teeth row with the stator teeth row at both a left position and a right position on either end of a central tilt line and transmits rotation to the output shaft while meshing the second rotor teeth row with the output teeth row at both the left and right positions on either end of the central tilt line.
