Specific embodiment
The embodiments described below are only the utility model part embodiments, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Consult Fig. 1, the transmission shaft fixed mechanism that the present embodiment provides is applied in the driving roller device of transport part of laminated medium processing unit, this driving roller device comprises transmission shaft 4 and is arranged on live roll 41 on transmission shaft 4, this transmission shaft 4 is arranged on the side plate 6 and 7 of transport part, and the transmission shaft fixed mechanism that the present embodiment provides namely is used for this transmission shaft 4 is fixed on side plate 6 and 7.
concrete, consult shown in Figure 2, the transmission shaft fixed mechanism that the present embodiment provides comprises two kinds, a kind of is the assembly 1 that comprises bearing housing 10 and bearing 30, another kind is the assembly 2 that has increased wave washer 20, assembly 2 and assembly 1 difference are to have added wave washer 20 between bearing housing 10 and bearing 30, thereby deformation occur after 20 assemblings of this wave washer can produce an axial force and prevent the play that produces because of matching gap between part, therefore assembly 2 is structures of the further optimization of assembly 1, the two ends of this transmission shaft 4 can be as shown in Figure 2 like this, one end is fixing with assembly 1, the other end is fixing with assembly 2, also can all fix with assembly 1 at two ends, perhaps two ends are all fixing with assembly 2.
This transmission shaft fixed mechanism specialization that the present embodiment provides is that this bearing housing 10 has adopted special structure, and as shown in Figure 3, this bearing housing 10 is the cylindrical structural of an interior sky, and it comprises an inner side surface 102 and an outer side surface 101.Along the circumferential direction be evenly distributed to few two flanged structures 14 on this outer side surface 101, radially outwards also be extended with an elastic arm 11 on this outer side surface 101.In the present embodiment, this elastic arm 11 also has an extension part 112 that along the circumferential direction extends, and this extension part 12 also forms the structure of similar flanged structure 14, and its effect is identical with flanged structure 14, plays the effect of fixing this bearing housing 10 on axial.Certainly, this elastic arm 11 can not have this extension part 112 yet, and is still, preferred, this elastic arm 11 is distributed on same circumference with this flanged structure 14, fixes the effect of this bearing housing 10 on this elastic arm 11 itself also just can equally with flanged structure 14 play axially like this.In addition, also be provided with two overhead structures 13 on this outer side surface 101, this overhead structure 13 and this flanged structure 14 axially spaced-apart certain distance along this bearing housing 10 on this outer side surface 101, that is to say, to keep at a certain distance away between this overhead structure 13 and this flanged structure 14, in order to hold the thickness of buck plate during assembling, namely, during assembling, this bearing housing 10 passes pilot hole, the edge of pilot hole embeds between the overhead structure 13 and flanged structure 14 of this bearing housing 10, and this overhead structure 13 plays axial fixation with this flanged structure 14.Concrete, these two overhead structures 13 are radially symmetrical, that is to say, if between these two overhead structures 13 line, this line will pass the center of this bearing housing.In addition, the several angle that staggers between this elastic arm 11 and this overhead structure 13, these elastic arm 11 ends be to being provided with salient point 111, and this salient point 111 is provided with a side of overhead structure 13 on the bearing housing 10 and extends.
Below in conjunction with the minutia of the pilot hole 71 of the side plate 7 shown in Fig. 4, introduce in detail bearing housing 10 that the present embodiment provides and the assembling mode of whole transmission shaft fixed mechanism.During assembling, first bearing 30 is put into bearing housing 10 and formed assembly 1, perhaps first wave washer 20 is put into bearing housing 10, and then put into bearing 30, form assembly 2.4 of the transmission shafts that then live roll 41 will be housed pass side plate 7 with assembly 1 and are inserted on transmission shaft 4 on side plate 6 and side plate 7, and assembly 2 passes the other end that side plate 6 is inserted in transmission shaft 4.Side plate 6 and side plate 7 have identical mounting hole configuration, describe in detail as an example of side plate 7 example in conjunction with Fig. 4.As shown in Figure 4, pilot hole 71 has two gap 72 in up and down, and is provided with an aperture 73 below the gap of pilot hole 72.Two gap 72 are also symmetrical, if line between the two also passes the center line of this pilot hole 72.When this gap 72 assembles for bearing housing 10, its overhead structure 13 passes, that is to say, during bearing housing 10 assembling, this overhead structure 13 aligns this gap 72 and inserts in pilot hole 71, this moment, flanged structure 14 and elastic arm 11 can prevent that bearing housing 10 from passing completely through this pilot hole 71, when flanged structure 14 was adjacent to this side plate 7, the salient point 111 of elastic arm 11 withstood side plate 7, and elastic arm 11 produces certain deformation.Then this bearing housing 10 is rotated a set angle, the angle that namely staggers between overhead structure 13 and elastic arm 11, this moment overhead structure 13 this gap 72 that can stagger, this bearing housing 10 is namely limited by overhead structure 13 and can not withdraw from this pilot hole 71 again, like this, overhead structure 13 coordinates this bearing housing 10 fixing in the axial direction with flanged structure 14.In addition, when bearing housing 10 this set angle of rotation, the salient point of elastic arm just can fall in aperture 73 in the effect of elastic force, thereby bearing housing 10 is pinned in sense of rotation.In addition, after the wave washer assembling, axial force of deformation generation can prevent the play because of matching gap generation between part, further improves the precision of joining of this transmission shaft fixed mechanism.From above-mentioned introduction as can be known, this transmission shaft means of fixation assembling that the present embodiment provides is simple, the unsettled problem of the conveying that can avoid the delivery roll axial float to bring again.
In addition, as shown in Figure 3, be extended with vertically many roots bar 15 on these bearing housing 10 inner side surfaces 102, preferably this rib 15 equidistantly distributes.This rib 15 makes between bearing housing 10 and bearing 30 assembling tightr, further improves and joins precision.
Above disclosed is only a kind of preferred embodiment of the utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
