Fig. 1 is the embodiments of the invention structural drawing.
Fig. 2 is sectional view and the application examples schematic representation of Fig. 1.
Embodiment
can be expressly understood technical spirit of the present invention and beneficial effect more for the auditor that the makes Patent Office especially public; The claimant general elaborates with embodiment's mode below; But the description to embodiment all is not the restriction to the present invention program, any according to the present invention design done only for pro forma but not substantial equivalent transformation all should be considered as technological scheme category of the present invention.
Fig. 1 is asked for an interview in
; The pump housing 1 and a back pump housing 2 before having provided one; This forward and backward pump housing 1,2 is linked together by one group of connecting bolt 13 of Fig. 2 signal each other; One chain wheel 3 is arranged in the front pump body cavity 11 of the preceding pump housing 1 rotationally; Side at this chain wheel 3 pump housing 2 towards the back constitutes a chain wheel axle 31; Surface in this chain wheel axle 31 one side of the pump housing 2 towards the back constitutes a tenon 311; The shape of cross section of this tenon 311 is rectangular, and on this tenon 311, offers a bolt hole 3111.On chain wheel axle 31, also set (being nested with) a preferred seal ring 312 of being filled the post of by rubber is earlier arranged.Constitute the first logical axle bed dish cavity 12 of ring one at an end of the preceding pump housing 1 pump housing 2 and the accent position that is positioned at front pump body cavity 11 towards the back again.The pump housing 2 constitutes the second logical axle bed dish cavity 22 of ring one equally towards end of the preceding pump housing 1 and the position that is positioned at the accent in pump housing chamber, back 21 and in the back; After being fitted to each other, first, second axle bed dish cavity 12,22 forms the axle bed dish receiving cavity of an integral body; And be installed with an axle bed dish 5 in the said axle bed dish receiving cavity that forms in these first, second 12,22 common cooperations of axle bed dish cavity, aforesaid forward and backward pump housing chamber 11,21 separated by this axle bed dish 5.Central authorities at axle bed dish 5 offer a chain wheel axle matching hole 51; By this chain wheel axle matching hole 51 axle bed dish 5 is placed on the chain wheel axle 31; And the hole wall by aforesaid seal ring 312 and chain wheel axle matching hole 51 forms sealing, avoids forward and backward pump housing chamber 11, ganging up between 21.
since axle bed dish 5 be when 1,2 assemblings of the forward and backward pump housing, just be installed on the chain wheel axle 31 and corresponding in first, second axle bed dish cavity 12,22; Therefore the processing to forward and backward pump chamber 11,21 seems very convenient in to the manufacture process of the forward and backward pump housing 1,2; Because before the axle bed dish 5 of not packing into, the space of forward and backward pump chamber 11,21 is relatively large.
preferably; On the dish edge of axle bed dish 5, offer a positioning hole 52; And on the pump housing 2 of back, offer a location screw hole 23, this positioning screw hole 23 is corresponding with positioning hole and pass through positioning screwn 231 screw-in positioning holes 52, thereby with axle bed dish 5 location.
aforesaid chain wheel axle 31 leans out axle bed dish 5 and is stretched in the pump housing chamber, back 21 and is in transmission connection with power transmission shaft 4; One end of power transmission shaft 4 shown in Figure 1 is that left end and actuating unit 6(Fig. 2 show) be in transmission connection; And the other end to be right-hand member be supported in the pump housing chamber, back 21 by bearing 43 rotationally; Promptly constitute the connection spindle nose 42 of a diameter at the right-hand member of this power transmission shaft 4 greater than the diameter of power transmission shaft 4 self towards an end of the preceding pump housing 1; In this connection spindle nose 42, promptly in the spindle nose chamber that connects spindle nose 42, constitute a rectangular shape and tenon chamber 421 that match with aforesaid tenon 311, and also constitute an axocoel 422 that communicates with tenon chamber 421 at the end that connects spindle nose 42.During assembling; Tenon 311 is inserted tenon chamber 421 makes tenon 311 cooperate with the 421 tenon fourths of the twelve Earthly Branches, tenon chamber; And make the left end of chain wheel axle 31 insert axocoel 422; Screw in aforesaid bolt hole 3111 with the bolt hole 41 of bolt 411 then, thereby whole chain wheel 3 is in transmission connection with transmission shaft 4 through the axial central authorities that are opened in transmission shaft 4.So the strong point of structure is: when transmission shaft 4 work and 3 rotations of drive chain wheel, can ensure both concentricitys, chain wheel 3 the jumping phenomenon of quivering can not occur, and promptly can ensure the robust motion of chain wheel 3.
Ask for an interview Fig. 2; In Fig. 2, illustrated the state that chain wheel teeth 32 on the chain wheel 3 matches with star wheel 7; Because the working principle of gear pump for food processing of the present invention belongs to known technology; For example can through to prior to the disclosed application number of the application be 201010177998.4,201010178005.5,101020522792.6 and the reading of 201020522795.X etc. obtain understanding, so the claimant is no longer superfluous and
