DUAL SPEED GEARBOXES, TRANSMISSIONS, AND APPARATUSES INCORPORATING THE SAME

摘要

Dual speed gearboxes, transmissions, and apparatuses incorporating the same are provided herein. Example embodiments include a first gear and a second gear that are coupled to an output spindle, a first bracket and a second bracket for moving the gears along the output spindle, an armature shaft with two different sized pinions, and an actuator that moves the brackets to bring the gears into contact with the pinions.

主权项

1. An assembly, comprising:
a first gear; a second gear, the first gear and the second gear held in spaced apart relationship by a gear spacer that is disposed therebetween, the first gear and the second gear being coupled to an output spindle; a first bracket; a second bracket, the first gear and the second gear being disposed between the first and second brackets, the first and second brackets being capable of moving along the output spindle; an armature shaft having a first armature pinion and a second armature pinion; and an actuator coupled with the first and second brackets, the actuator having a first position and a second position, when the actuator is in the first position, the first and second brackets are moved along the output spindle such that the first armature pinion engages with the first gear, when the actuator is in the second position, the first and second brackets are moved along the output spindle such that the second armature pinion engages with the second gear.
