The drive shaft 4 of electric motor 1 is being inserted into the through hole 31a of the pump rotor 31 of vane pump 100 and by blade After the positioning pin 46 of pump 100 is inserted into the location hole 3e of motor cover 3b, using bolt link pump case 40 and motor cover 3b, by This carries out the assembling between electric motor 1 and vane pump 100.It will be described in detail below.
Firstly, illustrating to assemble before assemble method between the electric motor 1 for illustrating present embodiment and vane pump 100 The problem of.
Before electric motor 1 and vane pump 100 are fitted together, in vane pump 100, pump rotor 31 be in not by It is fixed and in stator 33 free-moving state, therefore the bottom in stator 33 can be fallen under gravity into.At this In the case of, pump rotor 31 relatively moves in vertical direction relative to the 2nd side plate 37, the position of the through hole 31a of pump rotor 31 It is staggered with the position of the through hole 37a of the 2nd side plate 37.As a result, as the part of the through hole 37a of the 2nd side plate 37 by pump rotor The state of 31 side blocking.In this case, even if drive shaft to be made 4 runs through the through hole 37a of the 2nd side plate 37 and inserts Enter the through hole 31a to pump rotor 31, it is also difficult since the top end face 4b of drive shaft 4 is interferenceed with the side of pump rotor 31 Drive shaft 4 to be inserted into the through hole 31a of pump rotor 31.In this way, drive shaft 4 to be inserted into the through hole of pump rotor 31 The operation of 31a is cumbersome.Especially in the direction with the major diameter of pump rotor 31 with the consistent state of vertical direction by electric motor 1 and In the case that vane pump 100 fits together, due to the position of the through hole 31a of pump rotor 31 and the through hole of the 2nd side plate 37 The position of 37a is largely staggered, therefore the operation that drive shaft 4 is inserted into the through hole 31a of pump rotor 31 is more cumbersome.
As its countermeasure, in the present embodiment, it is formed with protrusion 50 in the 1st side plate 36 of vane pump 100, the protrusion 50 It is inserted into the through hole 31a of pump rotor 31.State before fitting together electric motor 1 and vane pump 100 as a result, Under, as shown in Fig. 2, the outer peripheral surface 50a of the inner peripheral surface contact protrusion 50 of the through hole 31a of pump rotor 31, to make protrusion 50 It holds pump rotor 31 and limits the falling into stator 33 of pump rotor 31.Thus, the through hole 31a and the 2nd side plate 37 of pump rotor 31 Through hole 37a between dislocation it is small.In particular, the position of the through hole 31a of pump rotor 31 and the perforation of the 2nd side plate 37 The position of hole 37a is staggered and dashing forward under the state (state shown in FIG. 1) that electric motor 1 and vane pump 100 fit together It measures accordingly in the gap risen between the inner peripheral surface of 50 outer peripheral surface 50a and through hole 31a.
It is inserted into drive shaft 4 through the through hole 37a of the 2nd side plate 37 To pump rotor 31 through hole 31a when, drive shaft 4 top end face 4b outer peripheral edge formed conical surface 4c be connected to pump rotor 31 Through hole 31a inner peripheral 31c, pump rotor 31 lifted upwards.The external splines 4a of drive shaft 4 enters interior flower as a result, In key 31b, external splines 4a and internal spline 31b are combined.
In the state that external splines 4a and internal spline 31b is combined, i.e., in the state that drive shaft 4 and pump rotor 31 link, such as Fig. 1 Shown, the through hole 31a of protrusion 50 and pump rotor 31 is configured in same heart shaped, in the outer peripheral surface 50a and through hole 31a of protrusion 50 There are gaps between inner peripheral surface.In addition, there is also gaps between the top end face 50b of protrusion 50 and the top end face 4b of drive shaft 4. Thus, when drive shaft 4 and pump rotor 31 rotate, protrusion 50 will not interference with drive shaft 4 and pump rotor 31.
As above, protrusion 50 has pump rotor 31 when drive shaft 4 to be inserted into the through hole 31a of pump rotor 31 The easy function of the insertion for being positioned such that drive shaft 4 to through hole 31a in stator 33.
According to the 1st above embodiment, effect as shown below is played.
The protrusion 50 of the through hole 31a of pump rotor 31 is inserted into due to being formed in the 1st side plate 36, by electronic horse When fitting together up to 1 and vane pump 100, when drive shaft 4 to be inserted into the through hole 31a of pump rotor 31, protrusion 50 is utilized Pump rotor 31 is positioned in stator 33.The center at the center and stator 33 that prevent pump rotor 31 as a result, is largely staggered, Therefore it can be improved the assemblability of vane pump 100.
Hereinafter, illustrating the variation of this 1st embodiment.
(1) in the above-described embodiment, mode protrusion 50 being integrally formed with the 1st side plate 36 is illustrated.? It can replace, as shown in Figure 3 be separately formed protrusion 50 relative to the 1st side plate 36.In particular, can also incite somebody to action Columned protrusion 50 is pressed into the slot 36b in the formation of the side of the 1st side plate 36.
In order to improve the sliding properties of pump rotor 31, need to carry out the side of the 1st side plate 36 slided for pump rotor 31 Grinding.In the case where protrusion 50 and the 1st side plate 36 are integrally formed, it is difficult to carry out the grinding operation.But by protrusion 50 It, can be into before protrusion 50 is pressed into the slot 36b of the 1st side plate 36 in the case where being separately formed relative to the 1st side plate 36 The grinding of the 1st side plate 36 of row, therefore the workability of grinding operation rises.
(2) in the above-described embodiment, prominent from the central part of the side of the 1st side plate 36 to protrusion 50 and be formed as and pump The through hole 31a of rotor 31 concentric columned mode is illustrated.It can also be as shown in Figure 4 in the 1st side plate 36 Side form multiple columned protrusions 51 and substitute protrusion 50.Fig. 4 be from 31 side of pump rotor the 1st side plate 36 and obtain Side view.Protrusion 51 is equipped at intervals with 3 on the same circle with 120 degree.
In the state that drive shaft 4 and pump rotor 31 link, in the outer peripheral surface of each protrusion 51 and the through hole of pump rotor 31 There are gaps between the inner peripheral surface of 31a.In addition, in the state of before fitting together electric motor 1 and vane pump 100, By making the outer peripheral surface of any one protrusion 51 of the inner circumferential face contact of through hole 31a of pump rotor 31, so that pump rotor 31 be supported In protrusion 51.
In addition, 1 can also only be arranged on plumb line in the case where being previously determined the installation direction of vane pump 100 A protrusion 51.
