Abstract
The invention discloses a telescopic double-diaphragm coupling which comprises a spline hub, a spline shaft and two connecting flanges. A first flange body extending outside is arranged at one end of the spline hub. A second flange body extending outside is arranged at one end of the spline shaft. Diaphragm sets are arranged between the first flange body and one connecting flange and between the second flange body and the other connecting flange. A dustproof cover is fixed to the second flange body and arranged on the spline shaft. The other end of the spline hub is clamped between the dustproof cover and the spline shaft. Installation holes are formed in the middle of the spline hub. Oil cups are fixed into the installation holes. An annular groove is formed in the spline hub and internally sleeved with a sealing ring. The telescopic double-diaphragm coupling is simple and compact in structure and reasonable in design; axial compensation is achieved through telescopic motion of the spline shaft and the spline hub, and the additional force applied to equipment due to coupling installation errors is reduced.
