Sticky coupling and sticky coupling testing test bed

The invention relates to a sticky coupling and a sticky coupling testing test bed. The sticky coupling comprises a drive rotating disc and a driven rotating disc. The drive rotating disc is connected with the driven rotating disc through bonding agents bonded to the two opposite end faces of the drive rotating and the driven rotating disc. The test bed comprises a base, a power mechanism, a test mechanism and a loading mechanism. The test mechanism comprises a torque rotating speed sensor arranged on the portion, connected to one end of the drive mechanism, of the base, a rotating cylinder connected to the other end of the torque rotating speed sensor through a transmission shaft in a fastened mode and an elastic component arranged on the rotating cylinder in an interference fit mode. The overloading mechanism comprises a supporting piece connected to the other end of the base in a fastened mode, a rotating shaft horizontally inserted into the supporting piece, a hand wheel connected to one end of the rotating shaft in a fastened mode and a loading cylinder connected to the other end of the rotating shaft in a fastened mode. The elastic component and the loading cylinder are coaxially arranged and in interference fit with each other. The loading cylinder is capable of moving along the outer edge of the elastic component in the axial direction. The drive rotating disc is connected to an output shaft of a motor. The driven rotating disc is connected to the torque rotating speed sensor.
