Gear box with variably coupled oscillation and rotation for kneading machine

Abstract

A gear box for a reciprocating kneader. A primary rotational gear is attached to a gear box primary shaft and rotates in concert therewith. A secondary rotational gear is engaged with the primary rotation gear and rotates therewith. A secondary shaft is attached to the secondary rotational gear and rotates therewith. A primary oscillation gear is attached to the gear box primary shaft and rotates therewith. A secondary oscillation gear is rotationally engaged with the primary oscillation gear and rotates on the secondary shaft. An eccentric is coupled to the secondary oscillation gear and rotates in concert therewith. A yoke is engaged with the eccentric and oscillates on an axis perpendicular to the secondary shaft in response to the lobe. The gearbox secondary shaft moves along its axis in concert with yoke oscillation. A housing is pivotally attached to the yoke and pivotally attached to a casing at a casing.

1 . A gear box for a reciprocating kneader comprising:
 a casing;   a gear box primary shaft adapted for coupling to a motor;   a primary rotational gear attached to said gear box primary shaft which rotates in concert with said gear box primary shaft;   a secondary rotational gear engaged with said primary rotation gear which rotates in concert with said primary rotational gear;   a gear box secondary shaft attached to said secondary rotational gear which rotates in concert with said secondary rotational gear;   a primary oscillation gear attached to said gear box primary shaft which rotates in concert with said gear box primary shaft;   a secondary oscillation gear engaged with said primary oscillation gear which rotates in concert with said primary oscillation gear wherein said secondary oscillation gear rotates on said gear box secondary shaft;   an eccentric coupled to said secondary oscillation gear wherein said eccentric rotates in concert with said secondary oscillation gear wherein said eccentric comprises lobes;   a yoke engaged with said eccentric wherein said yoke oscillates on an axis perpendicular to said gear box secondary shaft in response-to contact with said lobes of said eccentric during rotation and said gearbox secondary shaft moves along its axis in concert with yoke oscillation;   a housing pivotally attached to said yoke at a yoke pivot axis and pivotally attached to said casing at a casing pivot axis herein said yoke pivot axis and said casing pivot axis are not parallel; and   a coupling on said gear box secondary shaft adapted for attachment to said kneader.
