Abstract
Novel anti-reverse middle-opening pump disclosed in the utility model, comprise a main structure body, described main structure body is made up of main shaft, axle sleeve and the sleeve nut for locking main shaft and axle sleeve, and described main shaft is fixedly connected with axle sleeve by arranging fastening screw trip bolt by described sleeve nut.Add screw fixed structure with anti-reverse sleeve nut, simple to operate, easy for installation, middle-opening pump allows reversion can't occur that sleeve nut loosens, thus greatly reduces because sleeve nut loosens the maintenance cost causing rotor failure.
Description
Technical field
The utility model relates to the anti-reverse technical field of middle-opening pump, particularly the novel anti-reverse middle-opening pump of one.
Background technique
Tradition middle-opening pump sleeve nut is professional standard part (see professional standard B2204), a part for rotor part, screw-thread fit (with the screw-thread fit on main shaft) is utilized to be arranged on the main shaft of middle-opening pump, for fastening shaft sleeve, rotate together with rotor part, two ends of rotor axle sleeve all comes fastening with sleeve nut.And pump may exist excessive vibrations in practical operation, even reverse, easily loosen.Middle-opening pump round nut adopts lock washer anti-reverse, causes the anti-reverse problem of sleeve nut to be badly in need of solving.
Phenomenon is anyway there is in middle-opening pump actual motion, and conventional bushings nut thread rotation direction can ensure that the normal rotation direction of pump is run, once pump reversion, the reversion of short time, sleeve nut is due to screw thread oppositely just back-out, and this unexpected casual reversion easily causes sleeve nut thread looseness, cause screw thread stripped thread, finally cause rotor part play, shortened the working life of rotor, maintenance cost promotes greatly.
Model utility content
The utility model provides a kind of novel anti-reverse middle-opening pump effectively to solve the problems of the technologies described above.
For solving the problems of the technologies described above, the utility model provides a kind of novel anti-reverse middle-opening pump, comprise a main structure body, described main structure body is made up of main shaft, axle sleeve and the sleeve nut for locking main shaft and axle sleeve, and described main shaft is fixedly connected with axle sleeve by arranging fastening screw trip bolt by described sleeve nut.
Especially, described sleeve nut is provided with inner bore of step in described main shaft and axle sleeve joint.
Especially, described sleeve nut is provided with threaded interior hole in described fastening screw trip bolt and axle sleeve joint.
The beneficial effects of the utility model:
The novel anti-reverse middle-opening pump that the utility model provides, screw fixed structure is added with anti-reverse sleeve nut, simple to operate, easy for installation, middle-opening pump allows reversion can't occur that sleeve nut loosens, thus greatly reduces because sleeve nut loosens the maintenance cost causing rotor failure.
Accompanying drawing explanation
Fig. 1 is traditional middle-opening pump composition structural representation;
Fig. 2 is novel anti-reverse middle-opening pump composition structural representation described in the utility model;
Fig. 3 is the enlarged view of I position in Fig. 2.
In figure: 1 sleeve nut, 2 axle sleeves, 3 main shafts, 4 fastening screw trip bolts, 5 inner bore of step, 6 threaded interior holes.
Embodiment
Embodiment 1:
As shown in Figure 1, traditional middle-opening pump adopts sleeve nut 1 to complete structure composition, and sleeve nut 1 uses single being threaded with main shaft 3 and axle sleeve 2, because rotor is in rotation status, there is clockwise and anticlockwise.
As shown in Figures 2 and 3, novel anti-reverse middle-opening pump disclosed in the present embodiment, comprise a main structure body, described main structure body is by main shaft 3, axle sleeve 2 and form with the sleeve nut 1 of axle sleeve 2 for locking main shaft 3, and described sleeve nut 1 is followed closely be fixedly connected with axle sleeve 2 by described main shaft 3 by being arranged fastening screw 4.
Described sleeve nut 1 is provided with inner bore of step 5 in described main shaft 3 and axle sleeve 2 joint.Described sleeve nut 1 is provided with threaded interior hole 6 in described fastening screw trip bolt 4 and axle sleeve 2 joint.
Claimant states, person of ordinary skill in the field is on the basis of above-described embodiment, by above-described embodiment step, combined with the technological scheme of model utility content part, thus the new method produced, also be one of record scope of the present utility model, the application, for making specification simple and clear, no longer enumerates other mode of execution of these steps.
The technology path being different from prior art in the present embodiment is:
Namely novel anti-reverse sleeve nut 1 increases fastening screw trip bolt 4 and locks sleeve nut 1 and rotate when starting to install, when such rotor positive and negative direction rotates, axle sleeve 2 and sleeve nut 1 all can not produce loosening automatically.Solve the loosening problem of middle-opening pump sleeve nut fast and easily with easy fastening screw trip bolt 4, and do not affect use.After axle sleeve 2 installed by main shaft 3, first lock with sleeve nut 1, inner bore of step leaves surplus, till holding out against axle sleeve 2 completely, lock the rotation of sleeve nut 1 again with 2 fastening screw trip bolts 4, thus reach the synchronous axial system of sleeve nut 1 and axle sleeve, main shaft 3, tight effect.
The another statement of claimant, the utility model illustrates implementation method of the present utility model and apparatus structure by above-described embodiment, but the utility model is not limited to above-mentioned mode of execution, namely do not mean that the utility model must rely on said method and structure could be implemented.Person of ordinary skill in the field should understand; to any improvement of the present utility model; implementation method equivalence selected by the utility model is replaced and the interpolation of step, concrete way choice etc., all drops within protection domain of the present utility model and open scope.
The utility model is not limited to above-mentioned mode of execution, and all employings and the utility model analog structure and method thereof realize all mode of executions of the utility model object all within the utility model protection domain.
