Abstract

The utility model relates to a rotor and a main/auxiliary shaft structure of a rotor pump. An external spline at one end of a main/auxiliary shaft is matched and connected with an internal spline on the rotor; spline grooves and teeth are evenly distributed on the external spline and the internal spline, and corresponding internal and external positioning mark grooves and teeth are further formed on the external spline and the internal spline; and the internal and external positioning mark grooves and teeth are spline grooves and spline teeth different from the spline grooves and the spline teeth on the external spline and the internal spline in size or angle. The original internal and external splines are uniform distributed teeth and grooves with the same size and angle. Most of the internal and external spline teeth and grooves in the matching positions are processed according to the original size, and only one or more teeth and grooves are processed into different sizes and angles and serve as internal and external positioning mark teeth and grooves. Once the rotor is worn and replaced, the rotor can be mounted in the direction of the internal and external positioning mark teeth and grooves, and the clearance between the rotor and a pump body can return to the original state, so that the clearance is not required to be tested again, a user doesn't need a round trip, the use is more convenient, and the use cost is further reduced.

Description

Rotor pump rotor and major and minor axle construction

Technical field

The utility model relates to a kind of linkage structure of rotor and major and minor between centers of rotor pump rotor, particularly a kind of rotor pump, rotor pump rotor and major and minor axle construction.

Background technique

Splined shaft has been widely used on the mechanical transmissioning piece, because of it have bearing capacity big, feel relieved, guidance quality is good and the intensity height, therefore it often is used to transmit being fixedly connected of medium or big load again, as in the industry of rotor pump, rotor is connected with regard to adopting uniform spline with major and minor between centers, in addition because of rotor pump has special directed requirement in configuration, promptly between the pump housing and rotor, the gap between rotor and rotor all will must adjust and just can dispatch from the factory within the specific limits by technical standard.But the user is through the service firing of regular period, continuous effect between rotor and medium, wearing and tearing, gap between the pump housing and rotor, ouput force are also along with continuous variation simultaneously, even to cisco unity malfunction, at this moment must adjust or change rotor, after new rotor was installed in transposing, needing that also rotor is made clearance test again could use, so also need to transport whole pump back the manufacturer aptitude test, tossing to and fro has increased the user cost that many inconvenience has improved the user again to the user.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of rotor pump rotor and major and minor axle construction are provided, be processed with alignment mark at rotor and the major and minor axle place of being connected, so that user oneself carries out the maintenance or the transposing of rotor by alignment mark, need not make clearance test after the new rotor transposing yet, make the rotor pump user use the more convenient user cost that reduced again.

The technical scheme in the invention for solving the above technical problem is: rotor pump rotor and major and minor axle construction, external splines and epitrochanterian internal spline on major and minor axle one end are connected, on described internal spline, the external splines uniform except that having, equirotal spline, the spline tooth, also have inside and outside alignment mark groove of corresponding double as and inside and outside alignment mark tooth, described inside and outside alignment mark groove, the alignment mark tooth is all with internal spline, external splines on spline tooth, spline size or angle spline and spline tooth inequality.

Compared with prior art, advantage of the present utility model is: former rotor and master, in the countershaft joint, external splines all is uniform, equirotal spline tooth and groove, now with in the cooperation place, spline tooth on the external splines, groove is most of still by life size processing, one or more spline tooths are only arranged, groove is processed into size, in the different and double as of angle, the outside fix notch, groove, though make the master, the processing of countershaft and rotor has increased some troubles, but in this, the outside fix notch, after the groove processing, in case rotor wear again can be along in this after changing new rotor, the outside fix notch, the groove direction is installed, make the gap between the rotor and the pump housing return to original state, therefore just do not need to test again again the gap, as long as the user repurchases a rotor and just can oneself change, do not need to be transported to again manufacturer's test and toss to and fro, use the more convenient user cost that reduced again.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

On the external splines 1 of main shaft 2 one ends, except that a plurality of external spline teeth 3 that uniform normal size is arranged, external splines groove 4, also have little spline tooth 5 double as outside fix notch, the both sides of little spline tooth 5 are intersected and are the β angle, and 0 °＜β＜180 °, as shown in Figure 1 and Figure 2.

On the external splines 7 of main shaft 8 one ends, except that a plurality of external spline teeth 3 that uniform normal size is arranged, external splines groove 4, also have two big spline tooth 10 double as outside fix notch, two between cog also have little spline 9 double as outside fix mark grooves to use, as Fig. 4, shown in Figure 5.

And have on the rotor 6 that main shaft 2 cooperates the internal spline 1 that matches ', have on it inner spline groove 3 ', inner spline gear 4 ', major part is uniform normal size, alignment mark groove in the inner spline groove 5 ' double as that cooperates with little spline tooth 5, the identical β angle that is of the fit angle of its groove with tooth, as shown in Figure 3.

In like manner, have on the rotor 11 internal spline 7 that matches ', have on it inner spline groove 3 ', two interior alignment mark grooves of interior big spline 10 ' double as that cooperate with big spline tooth 10 of inner spline gear 4 ' also have, location notch in the interior little spline tooth 9 ' double as that cooperates with little spline 9, as shown in Figure 6.

During use, rotor 6 links into an integrated entity with main shaft 2, and connects by the position of inside and outside alignment mark spline, tooth.

Rotor 11 links into an integrated entity with main shaft 8, and connects by the position of inside and outside alignment mark spline, tooth.

Between rotor and countershaft cooperate and rotor and main shaft between cooperate identical.Countershaft schemes also not draw with regard to omission, does not describe.
