Revolving force transmitting assembly, photosensitive drums and handle box first embodiment
See Fig. 3, handle box has box body 1 and is rotatably supported in the photosensitive drums 2 between box body 1 end walls.
See Fig. 4, photosensitive drums 2 has drum barrel 21 and is installed on the revolving force transmitting assembly 22 of an axial end of drum barrel 21, and drum barrel 21 is made up of aluminum pipe and the photosensitive material layer be coated on outside aluminum pipe.
See Fig. 5, revolving force transmitting assembly 22 is made up of rotational force transmitting part 221, axial limiting parts 222, torsionspring 223 and drum gear 224.Drum gear 224 is provided with container cavity 2241 uncovered on an one axial end, another axial end is formed with the pilot hole 2242 be communicated with container cavity 2241.
See Fig. 6, rotational force transmitting part 221 is made up of the revolving force acceptance division 2212 of columned guide rod 2211 and an axial end being positioned at guide rod 2211.The radial outer wall of guide rod 2211 is provided with the output arm 22111 radially extended outwardly.Revolving force acceptance division 2212 is formed with groove 22121 in the outer end wall 22123 of guide rod 2211, groove 22121 runs through revolving force acceptance division 2212 along the radial direction of guide rod 2211, the outer end wall 22123 of groove 22121 both sides is respectively formed with a revolving force receptor arm 22122 along the axial evagination of guide rod 2211, concave surface 221221, two the revolving force receptor arm 22122 and groove 22121 side of revolving force receptor arm 22122 is formed for receiving the revolving force of driving shaft applying arm are all arranged symmetrically with about the axis centre of guide rod 2211.The direction of revolving force acceptance division 2212 is axially pointed to along guide rod 2211, the side 221222 of revolving force receptor arm 22122 along guide rod 2211 radial direction back to guide rod 2211 is shunk gradually, and namely this side 221222 reduces gradually with the axis spacing of guide rod 2211 and forms a smooth surface.Axially point to the direction of revolving force acceptance division 2212 along guide rod 2211, outer end wall 22123 is shunk gradually along the direction near revolving force receptor arm 22122 and forms a smooth surface.
See Fig. 7, the face shaping of drum gear 224 is roughly cylindrical, and the radial outer wall being positioned at the axial approximately middle part of drum gear 224 is provided with spiral gear 2240, and the revolving force for being received by drum gear 224 passes to other rotary parts; The inwall that container cavity 2241 is parallel to the axis of drum gear 224 is provided with the output arm 2244 that the radial center towards drum gear 224 extends.Another axial end of guide rod 2211 is successively through the through hole be formed on axial limiting parts 222, torsionspring 223, container cavity 2241 arrive the pilot hole 2242 of clearance fit with it, thus rotational force transmitting part 221 can be moved back and forth along the axially relative drum gear 224 of guide rod 2211; In the circumference of drum gear 224, output arm 22111 is in the position of input arm 2244 and input arm 2244 abutting contact.
See Fig. 5 to Fig. 7, a torque arm of torsionspring 223 is fixed on an output arm 22111, another torque arm is fixed on the fixed leg 2243 that is formed in container cavity 2241, along the circumference of drum gear 224, make output arm 22111 between two input arm 2244, namely torsionspring 223 elastic restoring force circumferentially forces output arm 22111 away from input arm 2244.Axial limiting parts 222 are placed on the opening end of container cavity 2241, and torsionspring 223 elastic restoring force vertically forces output arm 22111 against axial limiting parts 222.When the revolving force applying arm 021 of driving shaft 02 connects with revolving force receptor arm 22122, the domed ends 022 of driving shaft 02 is positioned at groove 2212, has gap between the both sides of domed ends 022 and groove 22122.
See Fig. 8, handle box is loaded the process in printer host, namely fall machine process, when the arranged direction that revolving force applies the axis of arm 021 and groove 22121 is almost parallel, handle box driven rotary power receiving-member 221 moves along direction shown in Fig. 8 arrow along the direction near driving shaft 02, the domed ends 022 of driving shaft 02 directly enters in groove 22121, then driving shaft 02 rotates around its axis and makes revolving force apply arm 021 to be resisted against concave surface 221221 place and driven rotary power receiving-member 221 rotates around the axis of guide rod 2211, make output arm 22111 against input arm 2244, drum gear 224 is driven to rotate around its axis, and then drive the drum barrel of photosensitive drums and the rotation of other rotary parts.
See Fig. 9, handle box is loaded the process in printer host, namely fall machine process, when revolving force applies the axis of arm 021 and the arranged direction of groove 22121 folds an angle, handle box driven rotary power receiving-member 221 moves along direction shown in Fig. 9 arrow along the direction near driving shaft 02, the domed ends 022 of driving shaft 02 is first against outer end wall 22123, along with revolving force receiving-member 221 continues mobile along direction shown in arrow, the outer end wall 22123 that extruding is tilted by domed ends 022, rotational force transmitting part 221 is moved down vertically while the axial-rotation of guide rod 2211, thus make domed ends 022 enter groove 22121, along with driving shaft 02 is around its axial-rotation, driven rotary force transmission member 221 rotates, drive drum gear rotates, and then drive the drum barrel of photosensitive drums and the rotation of other rotary parts.
See Figure 10, handle box is pulled down process from main frame, due to the existence of groove 22121, domed ends 022 is by the constraint of groove two side, the two-port of groove 22121 is to its nothing constraint, the axis of guide rod 2211 and the axis of driving shaft 02 can form a low-angle angle under external force, and rotational force transmitting part 221 easily departs from along direction shown in Figure 10 arrow and driving shaft 02 and connects.
Revolving force transmitting assembly, photosensitive drums and handle box second embodiment
As the explanation to revolving force transmitting assembly of the present invention, photosensitive drums and handle box second embodiment, only the difference with above-mentioned revolving force transmitting assembly, photosensitive drums and handle box first embodiment is described below.
See Figure 11, the bottom surface 311 of the groove on the revolving force acceptance division 31 of rotational force transmitting part 3 is a plane, bottom surface 311 and the intersection of groove two side are curve 3111 towards the axis projection of guide rod 32 and curve 3112, curve 3111 is arranged symmetrically with the axis centre of curve 3112 about guide rod 32, axis along guide rod 32 points to the direction of revolving force acceptance division 31, and the spacing between the two side of groove and the axis of guide rod 32 increases gradually.
In the process of machine that falls, along the circumference of guide rod 32, the domed ends of driving shaft directly can enter groove from larger circumferential angle, improves the smoothness of the machine that falls of handle box.Because groove two-port is trumpet type, minimizing driving shaft and rotational force transmitting part 3 are in the obstruction departing from connection process.
