Embodiment 1
[0023] A flexible coupling with variable stiffness based on magnetorheological grease, including a drive shaft connecting plate 1, an electromagnetic coil 3, N studs 4, N magnetorheological grease 6, and a driven shaft connecting plate 7;
[0024] There are N first hollow through holes 2 on the disk surface of the driving shaft connection disk 1, and a groove is provided on the side of the driving shaft connection disk 1, and the electromagnetic coil 3 is placed in the groove; the disk surface of the driven shaft rotating disk 7 is provided with N The N second hollow through holes 8 opposite to the first hollow through holes 2; the magneto-rheological grease 6 is a through-hole sleeve structure, and its axial length is less than the thickness of the drive shaft connection plate 1, and the magneto-rheological grease 6 6 is set on the stud 4 that runs through the first hollow through hole 2 and the second hollow through hole 8, and at the same time, the two ends are respectively ...
Embodiment 2
[0026] On the basis of Embodiment 1, N hollow through holes 2 are evenly distributed.
Embodiment 3
[0028] On the basis of any one of the above embodiments, N=4.
