Embodiment

It is described in further detail with reference to Fig. 1 to 7 pairs of the utility model.

Circumferentially there is projection 10 a kind of motor, including electric machine casing 20 and end cap 30, the end of electric machine casing 20, convex The outer peripheral face of block 10 sets and the connecting hole 12 parallel with motor direction of principal axis is opened up on recess 11, projection 10, and connecting hole 12 is from outside End face is axially disposed to be communicated to recess 11, and described recess 11 is used to accommodating nut 41, the direction of the nut bore of nut 41 with The direction of connecting hole 12 is consistent, and the circumferential internal face of recess 11 is fitted with the side face of nut 41 and limits the circumference turn of nut 40 It is dynamic.

In above-mentioned technical proposal, circumferentially there is projection 10 in the end of electric machine casing 20, the outer peripheral face of projection 10 is set Recess 11 is put, is fitted by the circumferential internal face of recess 11 with the side face of nut 41, limits circumferentially rotating for nut 41, bolt 40 Screw rod be placed through the hole portion of end cap 30 and connecting hole 12 and couple with the nut 41 in recess 11, in bolt 40 and nut 41 In fastener cycle, it is ensured that the fixation of the circumferential position of nut 41, so that end cap 30 is fixed conveniently, fast with electric machine casing 20, lead to Cross bolt 40 with the cooperation of nut 41 to couple, not only eliminate the trouble of the tapping female bore on projection 10, and greatly improve electricity The bonding strength of casing body 20 and end cap 30.

Further, the face of the end on projection 10 positioned at electric machine casing 20 is concordant with the end face of electric machine casing 20, institute The bottom for stating recess 11 is that the two folding faces for being mutually 120 degree of angles are surrounded and face where two folding faces is axially in parallel with motor, institute The A/F for the recess 11 stated is coincide with the size of the relative edge of nut 41 and opening direction and motor are axially vertical, above-mentioned to be recessed The concrete structure in portion 11, can reliably limit nut 41 and circumferentially rotate, and described recess 11 is simple in construction, be easy to processing.

The both ends of the surface of the axial direction of recess 11 are parallel and the two spacing is consistent with the thickness of nut 41, thus define nut The position of 41 axial directions, nut 41 with after axial location limitation, being directly placed in recess 11, in fastener cycle by the circumference of nut 41 Middle operating personnel need not help nut 41, and end cap 30 fixes more convenient, quick with electric machine casing 20.

Described one end of recess 11 is connected with connecting hole 12, the other end is connected with breach 13, the opening direction of the breach 13 Be less than the A/F of recess 11 with the corresponding and A/F of the opening of recess 11, the screw rod of bolt 40 be placed through the hole portion of end cap 30 with And connecting hole 12 couples with the nut 41 in recess 11, breach 13 is at the avoidance position in screw rod precession path.

In above-mentioned technical proposal, by setting the breach 13 connected with the one end of recess 11, on the one hand, in dismounting electric machine casing 20 with end cap 30 when, be easy to operating personnel to directly take out nut 41 out of recess 11；On the other hand, breach 13 revolves in screw rod At the avoidance position of inbound path, the rod end part that such screw rod stretches out after screwing is located in breach 13, makes motor overall more tight Gather, neatly.

Illustrate actual installation process with reference to the accompanying drawings, nut 41 is placed in the recess 11 of electric machine casing 20 first, then On the end that the end face of end cap 30 is abutted in electric machine casing 20, adjustment end cap 30 is so that 12 pairs of the hole portion and connecting hole of end cap 30 Together, bolt 40 is placed through to the hole portion and connecting hole 12 of end cap 30, bolt 40 is tightened.
