Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but not as to any restriction of the present utility model.
A kind of down-hole flexible coupling, as Figure 1-3: include cross key shaft coupling 4 and cross-slot coupling 3, cross key shaft coupling 4 is connected with cross-slot coupling 3；Being provided with rubber blanket 1 between cross key shaft coupling 4 and cross-slot coupling 3, the centre bore of cross-slot coupling 3 is that square hole is connected with the square shaft on output shaft 2；The centre bore of cross key shaft coupling 4 is flat hole and the flat axle of motor 5 is connected.The key top of cross key shaft coupling 4 is sphere 6；The bottom land of cross-slot coupling 3 is sphere 6.The groove width of cross-slot coupling 3 is more than the key width of cross key shaft coupling 4.Rubber blanket 1 center is provided with cross bore, and cross bore shape is corresponding with the cross recess shape on cross-slot coupling 3.The cross bore straight flange at rubber blanket 1 center is provided with flange, and flange top shape is corresponding with the bottom land shape of cross-slot coupling 3.
Embodiment
This is such as
Shown in Fig. 1, when being embodied as, the coupling design between motor 5 and output shaft 2 is two parts, and cross-slot coupling 3 coordinates with cross key shaft coupling 4.Cross-slot coupling 3 centre bore is that square hole is connected with output shaft 2, and cross key shaft coupling 4 centre bore is that flat hole is connected with motor shaft, and cross key coordinates transmission with cross recess keyway, is lined with rubber blanket 1 in the gap between cross key and cross recess.Utilizing the six-freedom degree deflection error caused between rubber blanket 1 elastic deformation small electromotor axle and output shaft 2 due to part processing alignment error etc., rubber blanket 1 can also play cushioning effect simultaneously, it is ensured that motor steadily operates.
