Abstract
The invention discloses a matching structure of a star wheel and an eccentric shaft disc for a food processing gear pump, which belongs to the technical field of food processing machines. The matching structure comprises the star wheel, an eccentric shaft and the eccentric shaft disc, wherein the star wheel is sleeved on the eccentric shaft; and the eccentric shaft is connected with the eccentric shaft disc. The matching structure is characterized in that: a positioning column hole is formed in the eccentric shaft disc; a bolt hole is formed at the bottom of the positioning column hole; one end of the eccentric shaft is provided with a star wheel seat, the middle part of the eccentric shaft is provided with a positioning column, and the other end of the eccentric shaft is provided with a bolt head; the positioning column is accommodated in the positioning column hole; the bolt head is matched with the bolt hole; and the star wheel is arranged on the star wheel seat in a rotatable way. The invention has the advantages that: the quantity of parts is reduced, the structure is simplified and is more conveniently and quickly disassembled or mounted, and dirt cannot be accumulated in the bolt head and the bolt hole; and the position of a shaft sleeve can be limited by a flange on the end face of the star wheel seat, so that the shaft sleeve can be prevented from moving.
Description
Technical field
The invention belongs to the food processing machinery technical field, be specifically related to a kind of star wheel of gear pump for food processing and the cooperating structure of eccentric reel
Background technique
The star wheel of
known and gear pump for food processing that mentioned by application for a patent for invention publication No. CN101825084A and the cooperating structure of eccentric reel can be by shown in Figure 3, and star wheel 1 is fixed through eccentric shaft 2 and by screw and eccentric reel 3.There is following three places shortcoming at least in this structure: the one, and amount of parts is many, and for example eccentric shaft 2 and screw 21 are parts independently separately, cause processing and installing loaded down with trivial details; The 2nd, dismounting comparatively bothers; The 3rd, there is matching gap between screw and the eccentric shaft unavoidably, in use be prone to incrustation, influence food sanitation.
On the mirror, be necessary rationally to improve, the technological scheme that will introduce below is based on producing under this prerequisite
Summary of the invention
task of the present invention is to provide a kind of and helps to reduce component number, helps easy disassembly and be of value to the star wheel of the gear pump for food processing that embodies health and the cooperating structure of eccentric reel.
task of the present invention is accomplished like this, and a kind of star wheel of gear pump for food processing and the cooperating structure of eccentric reel comprise a star wheel, an eccentric shaft and an eccentric reel; Star wheel is nested with rotationally on eccentric shaft; And eccentric shaft is connected with eccentric reel, is characterised in that on described eccentric reel, to offer a locating column hole, and the bottom in this locating column hole is formed with a bolt hole; One end of described eccentric shaft constitutes the star wheel seat; The middle part constitutes locating column, and the other end constitutes a bolt head, and locating column is contained in the described locating column hole; And bolt head matches with described bolt hole, and described star wheel is arranged on the described star wheel seat rotationally.
are in a concrete embodiment of the present invention; Constitute a rib at described star wheel seat away from the circumferencial direction of an end end of said locating column; The central authorities of described star wheel are provided with an axle sleeve; Axle sleeve is nested with on the star wheel seat, and maintains the recessed road of a rib between the surface of this axle sleeve and star wheel, and described rib matches with the recessed road of rib.
offer operating groove on the end face of described star wheel seat in another concrete embodiment of the present invention.
in another concrete embodiment of the present invention, described operating groove is straight groove or cross recess.
Star wheel seat, locating column and bolt head that
technological scheme provided by the invention will be formed on the eccentric shaft match with star wheel, locating column hole and bolt hole respectively; Not only reduced number of components and parts with respect to prior art; Simplify the structure; And make dismounting or install more convenient, and can the productive set dirt in bolt head and bolt hole; Owing to be formed in rib on the star wheel seat end face and can implement spacingly, stop the axle sleeve play again to axle sleeve.
Description of drawings
Fig. 1 is the embodiments of the invention structural drawing.
Fig. 2 is the cooperation schematic representation of the eccentric shaft shown in Fig. 1, star wheel and eccentric reel.
Fig. 3 is the star wheel of the gear pump for food processing in the prior art and the matching chart of eccentric reel.
Embodiment
Fig. 1 and Fig. 2 are asked for an interview in
because explained in the structure of gear pump for food processing and working principle the specification by disclosed CN101825084A formerly and, promptly belong to known technology, so the claimant repeats no more.
Star wheel, eccentric shaft 2 and eccentric reel 3 shown in
Fig. 1 all are positioned at the pump housing 4; Shown in figure; On eccentric reel 3 and towards a side of star wheel 1, offer a locating column hole 31, the narrow base in locating column hole 31 contracts has a bolt hole 311.By bolt hole 311 shown in Figure 2 is blind hole, does not promptly run through eccentric reel 3.One end of eccentric shaft 2 is that the left end of shown position state constitutes star wheel seat 21; The middle part constitutes the diameter locating column 22 littler than the diameter of star wheel seat 21; And being right-hand member, the other end constitutes a bolt head 23; Aforesaid star wheel is arranged on the star wheel seat 21 of eccentric shaft 2 through axle sleeve 11 rotationally, and locating column 22 is suitable with locating column hole 31, and bolt head 23 matches with bolt hole 311.
remain with the recessed road 111 of a rib between the end face of aforesaid axle sleeve 11 and star wheel 1; And constitute a rib 211 at the circumferencial direction of the end face of star wheel seat 21; Rib 211 matches with the recessed road 111 of rib, thereby can stop axle sleeve 11 plaies effectively.Whole eccentric shaft 2 cooperates with eccentric reel 3, can avoid dirt to invade in the axle sleeve 11 effectively, has both ensured health, can play a protective role to axle sleeve 11 again.In order to embody operational convenience, on the end face of star wheel seat 21, offer one and be used to instrument such as sieve is criticized the operating groove 212 that operation is provided.
In sum, technological scheme provided by the invention has overcome the shortcoming in the prior art, has accomplished the invention task, has embodied the alleged technique effect of claimant
