Abstract
A circuit breaker includes an electrically insulative case and a handle rotatably coupled to the electrically insulative case. The circuit breaker also includes a gear train mechanism. The gear train mechanism includes a drive gear drivingly coupled to the handle and a plurality of pinions engaged with the drive gear. The drive gear is arranged to rotate the plurality of pinions in response to a rotation of the handle. The gear train mechanism also includes a rack engaged with the plurality of pinions. The rack is arranged to translate in response to a rotation of the plurality of pinions.
Claims20
A circuit breaker comprising:
- an electrically insulative case;
- a handle rotatably coupled to said electrically insulative case;
- and
- a gear train mechanism comprising:
- a drive gear drivingly coupled to said handle;
- a plurality of pinion gears engaged with said drive gear, each pinion gear of said plurality of pinion gears comprising a plurality of teeth., wherein said drive gear is arranged to rotate said plurality of pinion gears in response to a rotation of said handle;
- and
- a rack engaged with said plurality of pinion gears, wherein said rack is arranged to translate in response to a rotation of said plurality of pinion gears.
A gear train mechanism for a circuit breaker, the circuit breaker including a case and a handle that is arranged to rotate relative to the case, said gear train mechanism comprising:
- a drive gear drivingly coupled to the handle;
- a plurality of pinion gears engaged with said drive gear, each pinion gear of said plurality of pinion gears comprising a plurality of teeth, wherein said drive gear is arranged to rotate said plurality of pinion gears in response to a rotation of the handle;
- and
- a rack engaged with said plurality of pinion gears, wherein said rack is arranged to translate in response to a rotation of said plurality of pinion gears.
A method of manufacturing a circuit breaker, said method comprising:
- coupling a handle to an electrically insulative case, wherein the handle is rotatable relative to the electrically insulative case;
- coupling a drive gear to the handle, wherein the drive gear is arranged to rotate in response to a rotation of the handle;
- coupling a first pinion gear to the drive gear, the first pinion gear including a plurality of teeth;
- coupling a second pinion gear to the first pinion gear, the second pinion gear including a plurality of teeth, wherein the first pinion gear and the second pinion gear are arranged to rotate in response to a rotation of the drive gear;
- and
- coupling a rack to the second pinion gear, the rack arranged to translate in response to a rotation of the second pinion gear.
