The 2nd cylindrical shell 26 to the 1 cylindrical shells 25 external diameters are big, are formed with the 2nd gear (situation that is called internal tooth 33 is arranged later on) with external tooth 27 engagements on the inner peripheral surface of the 2nd cylindrical shell 26.
The hardness of the internal tooth 33 of the 2nd cylindrical shell 26 is set forr a short time than the hardness of the external tooth 27 of the 1st cylindrical shell 25.Thus, the external tooth 27 of internal tooth 33 to the 1 cylindrical shells 25 of the 2nd cylindrical shell 26 is worn and torn quickly.That is, make the 2nd cylindrical shell 26 wearing and tearing of choosing (in other words, make the wearing and tearing of external tooth 27 of the 1st cylindrical shell 25 slack-off) selectively.
Being shaped as of external tooth 27 and internal tooth 33 considered the shape of external tooth 27 that the input shaft 16 and the off-centre of output shaft 19 brings and the slip of internal tooth 33.For example, external tooth 27 mountain portion, be the top along facewidth direction is circular-arc etc. in cross sectional side view shown in Figure 5.
In addition, internal tooth 33 for considering slippage (amount of movement) so that when external tooth 27 slides with respect to internal tooth 33, the contact position of these internal tooths 33 and external tooth 27 width that can move along facewidth direction.Say that at length the facewidth L4 of internal tooth 33, L4 ' set greatlyyer than facewidth L5, the L5 ' of external tooth 27.
The 2nd cylindrical shell 26 of the 1st dividing body 20 and the 1st cylindrical shell 25 of the 1st dividing body 20 are chimeric loosely, the internal tooth 33 of the 2nd cylindrical shell 26 and 27 engagements of the external tooth of the 1st cylindrical shell 25.The 2nd cylindrical shell 26 of the 2nd dividing body 21 and the 1st cylindrical shell 25 of the 2nd dividing body 21 are chimeric loosely, the internal tooth 33 of the 2nd cylindrical shell 26 and 27 engagements of the external tooth of the 1st cylindrical shell 25.
Under the state of internal tooth 33 engagements of the external tooth 27 of the 1st cylindrical shell 25 and the 2nd cylindrical shell 26, between the inner peripheral surface of the outer circumferential face of the 1st cylindrical shell 25 and the 2nd cylindrical shell 26, be formed with the 1st gap 34, the inflow entrance 36 that the 1st gap 34 of the terminal side of the 1st cylindrical shell 25 and the 2nd cylindrical shell 26 is flowed into as lubricant oil 35.Lubricant oil 35 in the fuel tank 37 described later flows on internal tooth 33 and the external tooth 27 by inflow entrance 36.
In addition, union body 22 has the axial thrust pin 22a that relatively moves that the protruding end is spherical shape, limits the 1st cylindrical shell 25 and this gear shaft coupling portion 5 when being connected on plate 30 or the plate 32 at the central part of left and right directions both ends of the surface.
As shown in Figure 5, when the length (distance) of establishing the gap portion between the both ends of the surface that are formed on input shaft 16 and output shaft 19 was L0, the axial length L 3 (comprising thrust pin 22a) of axial length L 2, L2 ' and the union body 22 of the axial length L 1 of the 1st cylindrical shell 25, L1 ', the 2nd cylindrical shell 26 was set shortlyer than the distance L between both ends of the surface 0.Be L0〉L1, L1 ', L0〉L2, L2 '.In this embodiment, compare with the distance between each end face of input shaft 16 and output shaft 19, the axial length L 3 of axial length L 2, L2 ' and the union body 22 of the axial length L 1 of the 1st cylindrical shell 25, L1 ', the 2nd cylindrical shell 26 is less, but also can make the axial length L 3 of axial length L 2, L2 ' and union body 22 of axial length L 1, L1 ', the 2nd cylindrical shell 26 of the 1st cylindrical shell 25 littler than the distance of plate 30 and plate 32 (distance between plates from).
For the input shaft 16 of sealed mode evenly mixing device 1 and the output shaft 19 of drive unit 2 are linked, at first, via the gap portion between the both ends of the surface that are formed on input shaft 16 and output shaft 19, have than the length L 1 of distance L 0 weak point of above-mentioned gap portion, the 1st cylindrical shell 25 of L1 ' for input shaft 16 and output shaft 19 embeddings, the 1st cylindrical shell 25 is embedded the length L 2 of distance L 0 weak point with ratio gap part, the 2nd cylindrical shell 26 of L2 ', make external tooth 27 and internal tooth 33 engagements thus respectively.
Then, between the 1st dividing body 20 and the 2nd dividing body 21, configuration is set at the minor diameter part 38a (union body 22) than the union body 22 (comprising thrust pin 22a) of length L 3 short between the both ends of the surface of input shaft 16 and output shaft 19, make lip part 38b be connected to the forward end of the 2nd cylindrical shell 26, lip part 38b and the 2nd cylindrical shell 26 are linked by connection pieces such as bolt 31.
By like this, input shaft 16 and output shaft 19 can be linked.In addition, when linking, do not need to make sealed mode evenly mixing device 1 and the state of drive unit 2 to move, need before being attached on input shaft 16 or the output shaft 19, shaft coupling portion 5 be installed in advance yet from fixation.
As shown in Figure 4, when input shaft 16 is connected with output shaft 19,, also can input shaft 16 be connected with output shaft 19 by gear shaft coupling portion 5 even when overlooking under the situation of off-centre in the axle center of the axle center of input shaft 16 and output shaft 19.
With under the 1st dividing body 20 and the state that the 2nd dividing body 21 is connected, between the 2nd cylindrical shell 26 and plate 30 and plate 32, form the 2nd gap 48, described the 2nd gap 48 is communicated to the 1st gap 34 that is formed between the 1st cylindrical shell 25 and the 2nd cylindrical shell 26.
On the other hand, with input shaft 16 with after output shaft 19 usefulness gear shaft coupling portions 5 are connected, under the situation that the 2nd cylindrical shell 26 is pulled down, at first the connection piece 31 with union body 22 loosens, and pulls down union body 22 from the 2nd cylindrical shell 26.At this moment, because internal tooth 33 can be along the slip of facewidth direction, so by the 2nd cylindrical shell 26 is slided vertically, union body 22 easily can be pulled down with respect to external tooth 27.
After union body 22 is pulled down, move to the direction of leaving from output shaft 19 by the 2nd cylindrical shell 26 side (for example the 1st dividing body 20 sides), the 2nd cylindrical shell 26 is pulled down from the 1st cylindrical shell 25.In addition, by connection piece 32a and plate 32 being pulled down, the opposing party's's (for example the 2nd dividing body 21 sides) the 2nd cylindrical shell 26 being moved to the direction of leaving from input shaft 16, the 2nd cylindrical shell 26 is pulled down from the 1st cylindrical shell 25.
At this moment, because axial length L 2, the L2 ' of the 2nd cylindrical shell 26 set shortlyer than the distance L between both ends of the surface 0, so can be between both ends of the surface the 2nd cylindrical shell 26 of the 1st dividing body 20 and the 2nd dividing body 21 being pulled down to the outside respectively.
Under the situation that the 1st cylindrical shell 25 is pulled down, after the 2nd cylindrical shell 26 is pulled down, move to the direction of leaving from output shaft 19 by the 1st cylindrical shell 25 with a side, the 1st cylindrical shell 25 is pulled down from output shaft 19.
In addition, same, move to the direction of leaving from input shaft 16 by the 1st cylindrical shell 25 the opposing party, the 1st cylindrical shell 25 is pulled down from input shaft 16.
At this moment, because axial length L 1, the L1 ' of the 1st cylindrical shell 25 set shortlyer than the distance L between both ends of the surface 0, so can be between both ends of the surface the 1st cylindrical shell 25 of the 1st dividing body 20 and the 2nd dividing body 21 being pulled down to the outside respectively.
More than, according to this connection set, because the 2nd cylindrical shell 26 and union body 22 axial length L 2, L2 ', L3 separately set shortlyer than the distance L between both ends of the surface 0, even, also the 2nd cylindrical shell 26 and union body 22 can be chosen so sealed mode evenly mixing device 1 or drive unit 2 are moved from the state of fixation.
In addition, because axial length L 1, the L1 ' of the 1st cylindrical shell 25 sets shortlyer than the distance L between both ends of the surface 0, so, also the 1st cylindrical shell 25 can be chosen even sealed mode evenly mixing device 1 or drive unit 2 are moved from the state of fixation.
This fuel tank 37 form overlook for rectangle have the end container-like, be configured in the downside of gear shaft coupling portion 5.At length say, dispose 1 fuel tank 37 at the downside of two gear shaft coupling portions 5 that two input shafts 16 of sealed mode evenly mixing device 1 and two output shafts 19 of drive unit 2 are connected respectively.On fuel tank 37, be provided with the foot 39 of this fuel tank 37 of supporting.
