Abstract
An inner pin plate having an inner pin integrally formed thereon is arranged on an axial motor side of an external gear, the inner pin being capable of restraining rotation of the external gear on its axis. An inner pin plate functions as a part of a casing body of the reducer. An output flange of the reducer, integrally formed on the internal gear, is arranged on an axial counter-motor side of the external gear. On the axial counter-motor side of the external gear, an eccentric body shaft is supported by a casing body, through a first bearing, the output flange, the internal gear, and a cross roller bearing arranged between the internal gear and a casing body.
Claims8
A geared motor reducer to be coupled with a motor comprising:
- a planetary gear mechanism having an external gear, an internal gear meshing with the external gear, an eccentric body shaft for making the external gear rotate eccentrically, and an inner pin capable of restraining rotation of the external gear on its axis;
- an inner pin plate having the inner pin integrally formed thereon, the inner pin plate being arranged on an axial motor side of the external gear and functioning as a part of a casing body of the geared motor reducer, the reducer and the motor being capable of connecting through the inner pin plate;
- a first bearing which supports the eccentric body shaft on an axial counter-motor side of the external gear;
- an output flange which is integrated with the internal gear on the axial counter-motor side of the external gear, the output flange being arranged on an outer periphery of the first bearing;
- and
- a cross roller arranged between an outer periphery of the internal gear and the casing body.
