Abstract
A crown gear deceleration mechanism provided by the present invention includes: a stator including a crown gear; a rotor including another crown gear; and an output shaft coupled to the rotor. Stator includes a stator tooth row in which Nstator teeth are circularly arranged. Rotor includes: a first rotor tooth row in which Nteeth are arranged; and a second rotor tooth row in which Nteeth are arranged. Output shaft includes an output tooth row in which Nteeth are arranged. Rotor performs a precession while engaging the first rotor tooth row with the stator tooth row at places existing at both sides between which a devotion central line intervenes. Rotor transmits rotation to the output shaft while engaging the second rotor tooth row with the output tooth row at the places existing at both sides between which the devotion central line intervenes.
