Abstract
The invention provides a high-speed diaphragm coupler. Fixing assemblies are used in the high-speed diaphragm coupler for adjusting the transverse vibration of the transversely-vibrating vibration type diaphragm coupler in a positive and negative alternate installation manner according to the length of pins of pin bolts to ensure accurate positioning and high concentricity, it is avoided that the transversely-vibrating characteristic of the coupler is close to the rotating speed frequency of a rotor system, and the problem that vibration of a rotor is not stable under the high-speed condition can be solved. A connecting cavity of a second half coupler is a conical cavity. The contact area between the conical connecting cavity and the conical face of a main shaft is large, it is ensured that contact is good, the conical connecting cavity and the conical face of the main shaft do not loosen at a high speed, a diaphragm does not twist or deform after being installed, it is ensured that the total mass center of a bolt connecting piece falls onto the middle position of a diaphragm coupler diaphragm set, and vibration of the coupler in the operation process is further relieved.
