A kind of rotating actuator, comprising can be around the transmission projection and the transmission groove of same rotational, described transmission projection periphery is provided with the driving face that parallels to the axis, driving face is close to the line of contact at transmission groove oral area edge, make transmission projection and transmission groove mesh, described transmission projection periphery also is provided with the inclined-plane, location, and the spacing of inclined-plane, location and axis increases gradually from the top to the bottom, the transmission convex portion stretches into transmission groove during transmission, and middle part, inclined-plane, location is near passing groove oral area edge.
To stretch into the length of transmission groove be 1～5mm to described transmission projection during transmission.
Inclined-plane, described location reduces gradually from the top to bottom width.
Described transmission convex top is provided with the junction of taper, is convenient to the transmission projection and stretches in the transmission groove.
Between described transmission convex top and the transmission groove bottom surface is 0.5～5mm, prevents that both from conflicting and influence engagement driving.
Described driving face and transmission groove inner peripheral surface reduce wear along engagement.
The present invention also provides a kind of OPC drum core gear, comprise the transmission projection, transmission groove on the connecting piece that this transmission projection and actuation gear rotate constitutes rotating actuator, described transmission projection periphery is provided with the driving face of parallel shaft, driving face is close to the line of contact at transmission groove oral area edge, make transmission projection and transmission groove mesh, described transmission projection periphery also is provided with the inclined-plane, location, the spacing of inclined-plane, location and axis increases gradually from the top to the bottom, the transmission convex portion stretches into transmission groove during transmission, and middle part, inclined-plane, location is near the edge of transmission groove oral area.
The drum core gear is a kind of easily-consumed products, and link generally be installed in print or copier on, generally do not need to change, so the structure of transmission groove is for fixing, and transmission is raised with more variation.
The transmission projection of driving mechanism of the present invention is provided with the inclined-plane, location, stretch in the process of transmission groove in the transmission projection, the inclined-plane, location is gradually near transmission groove oral area edge, when being close to this edge, because driving face meshes with transmission groove oral area edge always, make the transmission projection in transmission groove, realize the location, even there is not the gap in line of contact on driving face and the transmission groove, transmission projection and transmission groove also can be easily separated and combined, therefore the wearing and tearing of transmission projection can be less, and noise also can be corresponding lower.

Embodiment
As shown in Figure 1, a kind of driving mechanism, comprise the transmission projection 1 and the transmission groove 2 that are arranged on two pedestals 3,4, transmission projection 1 part stretch in the transmission groove 2 and with its in the engagement of oral area edge, one of them pedestal will drive another one pedestal coaxial rotation thereupon when rotating.
As shown in Figure 2, the cross section of transmission projection 1 and transmission groove 2 is all roughly triangular in shape.The side face of transmission projection 1 is decided to be inclined-plane 11, three secondary surfaces 13 and three driving faces 12 by three and surrounds, and it is equivalent to be formed through cutting by a regular triangular prism.Wherein be decided to be corner angle that inclined-plane 11 is equivalent to regular triangular prism prune from the top with being tilted form, make the width at top greater than the width of its bottom.And driving face 12 is equivalent to the original side of tri-prism, be parallel to described rotation axis, secondary surface 13 is equivalent to the tri-prism side by the formation of partly pruning, and it is continuous with inclined-plane 11, location, its main purpose is to avoid in the engagement process, transmission projection 1 is stuck, and transmission projection 1 has formed irregular cone after cutting.
From Fig. 3 and 4 as can be seen, the equilateral triangle that the sectional shape of transmission groove 2 such as each angle are cut by the screens line 2a of broken line type, and also this equilateral triangle is consistent with the cross section size of above-mentioned tri-prism.Every limit of this equilateral triangle all is not a straight line, but is formed by connecting by the line of contact 2b at camber line 2c and two ends, and the purpose that camber line is set also is to prevent that transmission projection 1 can be stuck.Therefore, transmission groove 3 inner peripheral surface shapes do not have specific (special) requirements in fact, only need to satisfy to be large enough to hold the part that transmission projection 1 stretches into.
Shown in Fig. 5～7, when transmission projection 1 and transmission groove 2 do not engage, driving face 12 is close to engagement limit 2b, by three engagement limit 2b and three driving face 12 pairings, both have just realized engagement, axially relative movement, and can not radially relatively rotate, be decided to be and leave big gap between inclined-plane 11 and the screens line 2a.
Along with transmission projection 1 constantly stretches into, shown in Fig. 8～10, when degree of engagement reached 50%, driving face 12 still was close to engagement limit 2b, dwindles half and be decided to be inclined-plane 11 with screens line 2a gap.Because driving face 12 top width are little, and bottom width is big, make it and engagement limit 2b contact length increase.
Shown in Figure 11～13, transmission projection 1 and transmission groove 2 engage fully, driving face 12 still is close to engagement limit 2b, only depend on screens line 2a and be decided to be inclined-plane 11, at this moment, the transmission projection can not continue to stretch into toward in, and is not in place for fear of engaging, and leaves the gap of 0.5～5mm between transmission projection 1 top and groove 2 bottom surfaces.
Shown in 14～15, this transmission projection 1 side face is decided to be inclined-plane 11, secondary surface 13 except a driving face 12, one, also has a cambered surface 14, these cambered surface 14 parallel rotation axis, be mainly used in transmission groove 2 oral area edges and cooperate, stop transmission projection 1 and transmission groove 2 to relatively rotate.As shown in figure 16, the side face of this transmission projection 1 is decided to be inclined-plane 11 by two driving faces 12 and two, also comprise a cambered surface 14, the effect of this cambered surface 14 is similar, be provided with according to transmission groove 2 oral area shapes, avoid transmission projection 1 to cooperate, three driving faces 12 are set certainly have bigger transmission torsion with transmission groove 2, and simple in structure.
On printer or copier, be equipped with and order about the connecting piece that OPC drum core gear rotates, generally be provided with transmission groove 2 as shown in Figure 3 and Figure 4 on this connecting piece, because connecting piece is fixedly mounted on the equipment, generally can not change, and OPC drum core gear is a kind of easily-consumed products.
A kind of OPC drum core gear comprises the gear body, and this gear body one end end face is provided with transmission projection 1 as shown in Figure 2, and in order to make connecting piece and gear matched tight, an end that is provided with the transmission projection at the gear body relatively is provided with coaxial stage clip.
OPC drum core gear adopts said structure transmission projection, can cooperate with the line of contact at transmission groove oral area edge on the connecting piece, and is very close to each other between the two, during transmission, though both also are the contacts of line face, the Line of contact vertical rotation axis, make torsion increase, wearing and tearing reduce, and noise reduces.
