Embodiment 1
[0051] The test device for the interference fit force between the inner water jacket and the stator, such as Figure 4 As shown, it includes a stator fixing device and a twist sleeve 5;
[0052] The stator fixing device is used to fix the stator;
[0053] The twist sleeve 5, such as Figure 8 As shown, including head 51, torsion arm 52;
[0054] The head 51 is used to be sleeved and fixed on the inner water jacket.
[0055] Preferably, the head 51 is annular, and the inner circle of the annular head is provided with a plurality of ribs 511 along the axial direction.
[0056] The state of the interference fit between the stator and the inner water jacket is as follows: Figure 10 shown.
[0057] In the test device for the interference fit between the inner water jacket and the stator in Embodiment 1, the stator fixing device is used as the static part, and the twist sleeve is used as the moving part. When in use, the stator fixing device is used to fix the stator 8; the twi...
Embodiment 2
[0059] The test device based on the interference fit force between the inner water jacket and the stator of embodiment one, such as Figure 4 As shown, the stator fixing device includes a base 1, two end cover plates 3, a support shaft 2, multiple locking screws 6, and multiple locking nuts 61;
[0060] The base 1, such as Figure 5 As shown, it includes a bottom plate 11 and two side plates 12;
[0061] The lower ends of the two side plates 12 are respectively fixed on the bottom plate 11, and the upper ends are respectively provided with rectangular openings 121;
[0062] The end cover plate 3, such as Figure 6 As shown, the outer circumference is circular, and a support block 31 is fixed in the middle of the outer side of the end cover plate 3;
[0063] The support block 31 is an axisymmetric 2N polygon, and at least one set of distances between opposite sides is adapted to the width of the rectangular opening 121 on the upper end of the side plate 12 (that is, the supp...
Embodiment 3
[0077] Based on the test device for the interference fit between the inner water jacket and the stator of the second embodiment, the inner and outer edges of the end cover plate 3 are provided with an annular chute;
[0078] The torsion sleeve 5 also includes a plurality of bearing struts 4 and a plurality of bearings 7;
[0079] One end of the plurality of bearing struts 4 is respectively installed and fixed on the side of the annular head 51 of the twist sleeve 5;
[0080] The plurality of bearings 7 are respectively fixed on the other end of the plurality of bearing rods 4 and can rotate around the bearing rods 4 .
[0081] Although the convex ribs of the inner ring of the twist sleeve head are snapped into the pre-processed groove 91 of the outer ring of the inner water jacket 9, the ribs 511 of the inner ring of the twist sleeve head and the groove 91 of the aluminum ring of the outer ring of the inner water jacket 9 form a fit to achieve Force transmission, but due to p...
