TEST BENCH FOR EXPERIMENTAL STUDIES OF FLEXIBLE COUPLINGS Russian patent published in 2001 - IPC

FIELD: mechanical engineering, in particular, test equipment. SUBSTANCE: the test bench has supports installed on the foundation, coaxial shaft and axle for fastening of the half-couplings of the coupling under test positioned in the supports, loading device connected to the shaft. The axle is installed in the support for axial movement. The novelty is in the fact that the bench is provided with an axial loader made in the form of a double-acting drive cylinder hinge- mounted in a post and coupled to the axle, second support for accommodation of the shaft that is installed on antifriction sleeves in blocks for movement in guides with stops centering the shaft relative to the axle. The loading device is positioned between the shaft supports, it is made as a rocker hinge-joined at the ends to the piston rods of the double-acting drive cylinders that are hinge-mounted in the posts. A sleeve with a flexible member is hinge- mounted between one end of the rocker and the post of the drive cylinder in alignment with the drive cylinder rod. EFFECT: determination of torsional, radial and axial rigidities of the coupling under test at static and dynamic loads, as well as life tests of the coupling in the conditions of cyclic loads, simulation of the processes of start, acceleration, braking and self-sustained vibrations. 3 cl, 2 dwg
