Process for installing original drive gear on a laser printer toner cartridge drum
View Patent ↗A method is disclosed. The method provides an assembly that contains a first drum-cylinder having an inner periphery surface and a drive gear assembly, wherein a portion of the drive gear assembly is in contact with the inner periphery surface, separates the drive gear assembly from the first drum-cylinder, inserts the portion of the drive gear assembly into a second drum-cylinder, and couples the drive gear assembly to the second drum-cylinder.
1. A method comprising:
providing an assembly that comprises a first drum-cylinder having an inner periphery surface and a gear assembly, wherein a portion of the gear assembly is in contact with the inner periphery surface and wherein the portion of the gear assembly includes a pair of slots;
separating the gear assembly from the first drum-cylinder;
inserting the portion of the gear assembly into a second drum-cylinder;
positioning the portion of the gear assembly and the second drum-cylinder between a pair of moveable arms; and
moving the moveable arms toward the portion of the gear assembly to couple the gear assembly to the second drum-cylinder by crimping the second drum-cylinder into the pair of slots.
2. The method of claim 1 , wherein the second drum-cylinder is made of aluminum.
3. The method of claim 1 , wherein the second drum-cylinder is made of aluminum and has an anodized surface.
4. The method of claim 1 , wherein the gear assembly is coupled to the second drum-cylinder having a torque failure value of at least 5 ft. lbs.
5. The method of claim 1 , wherein the gear assembly is a drive gear assembly.
6. The method of claim 1 , wherein the gear assembly is a helical gear assembly.
7. The method of claim 1 , wherein positioning the portion of the gear assembly and the second drum-cylinder between a pair of moveable arms includes aligning the slots with the moveable arms.
8. A method comprising:
providing an assembly that comprises a first drum-cylinder having an inner periphery surface and a gear assembly, wherein a portion of the gear assembly is in contact with the inner periphery surface and wherein the portion of the gear assembly includes a pair of slots;
providing means for separating the gear assembly from the first drum-cylinder; separating the gear assembly from the first drum-cylinder;
providing means for joining the gear assembly and a second drum-cylinder;
joining the gear assembly and the second drum-cylinder;
positioning the gear assembly and the second drum-cylinder between a pair of moveable arms; and
moving the moveable arms to crimp the second drum-cylinder into the slots and thereby coupling the gear assembly to the second drum-cylinder.
9. The method of claim 8 , wherein the gear assembly is a drive gear assembly.
10. The method of claim 8 , wherein the gear assembly is a helical gear assembly.
