FIG. 2 is a schematic diagram of a partial cross-sectional structure in the novel oil pump shaft.
In the figure, 1, a main body; 2. a connection part; 3. a spline; 4. a positioning part; 5. positioning a shaft core; 6. a positioning ring; 7. positioning the convex; 8. a set screw; 9. reinforcing the spacer bush.
Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
As shown in fig. 1 and 2, this novel oil pump shaft, including main part 1, detachable connection has connecting portion 2 on main part 1, spline 3 has on connecting portion 2, main part 1 tip outer lane department has the location portion 4 of axial extension, main part 1 tip intermediate position has the location axle core 5 of axial extension, location portion 4 and location axle core 5 looks interval and be formed with the constant head tank between these two, set up the core groove that supplies location axle core 5 to assemble into in connecting portion 2, still have the constant head tank 6 that stretches into in the constant head tank on connecting portion 2, circumference array has a plurality of location protruding 7 on the constant head tank cell wall on main part 1, set up a plurality of confession corresponding location protruding 7 location locating hole that stretches into on connecting portion 2, fixedly meet through set screw 8 between main part 1 and the connecting portion 2, and the junction of this main part 1 and connecting portion 2 still is equipped with the enhancement spacer 9 that improves joint strength, make main part 1 and connecting portion 2 reach high-efficient location through a plurality of location structures, afterwards fix through set screw 8, connect between the completion, when spline 3 changes, only need the main part 2 alone, reduce cost is kept for changing 1 when spline 3 changes.
Further, the reinforcing spacer 9 is in an I shape, the outer ring and the inner ring of the positioning part 4 are provided with grooves I, the outer ring of the connecting part 2 and the positioning ring 6 are provided with grooves II, the outer ring and the inner ring of the reinforcing spacer 9 are respectively arranged in the corresponding grooves I and the corresponding grooves II, the outer ring and the inner ring of the reinforcing spacer 9 are stably arranged, the positioning limiting purpose is achieved, and the connecting strength between the main body 1 and the connecting part 2 is further improved.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
Although the terms of the main body 1, the connecting portion 2, the spline 3, the positioning portion 4, the positioning shaft core 5, the positioning ring 6, the positioning boss 7, the set screw 8, the reinforcing spacer 9, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely for convenience in describing and explaining the nature of the utility model; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present utility model.
