Drive gear for extended drive shaft
A cartridge drive gear assembly for holding a drum coupling includes a drive gear having an outer surface and an inner surface, the inner surface including inner projections which extend into the interior of the drive gear and includes at least two voids disposed on opposing sides of the inner projections, and at least one slot disposed in the inner surface.
1. A cartridge drive gear assembly for holding a drum coupling comprising:
a drive gear having an outer surface and an inner surface, the inner surface including inner projections which extend into the interior of the drive gear and includes at least two voids disposed on opposing sides of the inner projections; and
at least one slot disposed in the inner surface,
wherein the at least one slot is disposed in the inner surface and separated from a top surface of the inner projections.
2. The cartridge drive gear assembly of claim 1 further comprising a clip sized to be held by the at least one slot.
3. The cartridge drive gear assembly of claim 2 wherein the at least one slot comprises two slots disposed in opposing portions of the inner surface.
4. The cartridge drive gear assembly of claim 3 further comprising a drum coupling, the drum coupling including a shaft, a spherical driving portion at one end of the shaft and a driven portion at the opposing end of the shaft, the spherical driving portion including two ends of a pin extending out from the surface of the spherical driving portion,
wherein the spherical driving portion is disposed at least partially within the inner projections, and
wherein the ends of the pin are at least partially disposed in the opposing voids of the inner projections.
5. The cartridge drive gear assembly of claim 4 wherein the clip is held in place by the two slots.
6. An OPC drum assembly comprising:
an OPC drum; and
a first end of a drive gear mated to one end of the OPC drum, a second end of the drive gear having an outer surface and an inner surface, the inner surface including inner projections which extend into the interior of the drive gear and includes two voids disposed on opposing sides of the inner projections, the drive gear further including at least one slot disposed in the inner surface, wherein the at least one slot is disposed in the inner surface and separated from a top surface of the inner side projections.
7. The OPC drum assembly of claim 6 further comprising a clip sized to be held by the at least one slot.
8. The OPC drum assembly of claim 7 wherein the at least one slot comprises two slots disposed in opposing portions of the inner surface.
9. The cartridge drive gear assembly of claim 8 further comprising a drum coupling, the drum coupling including a shaft, a spherical driving portion at one end of the shaft and a driven portion at the opposing end of the shaft, the spherical driving portion including two ends of a pin extending out from the surface of the spherical driving portion,
wherein the spherical driving portion is disposed at least partially within the inner projections, and
wherein the ends of the pin are at least partially disposed in the opposing voids of the inner projections.
10. An OPC drum assembly comprising:
an OPC drum; and
a first end of a drive gear mated to one end of the OPC drum, a second end of the drive gear having an outer surface and an inner surface, the inner surface including inner projections which extend into the interior of the drive gear and includes two voids disposed on opposing sides of the inner projections, the drive gear further including at least one slot disposed in the inner surface, wherein the inner projections comprise a plurality of ribs having at least one rounded portion.
11. A cartridge drive gear assembly for holding a drum coupling comprising:
a drive gear having an outer surface and an inner surface, the inner surface including inner projections which extend into the interior of the drive gear and includes at least two voids disposed on opposing sides of the inner projections; and
at least one slot disposed in the inner surface, wherein the inner projections comprise a plurality of ribs having at least one rounded portion.
