Abstract

The invention discloses a gearbox high-speed-level vibration mode testing device and a testing method, and relates to the technical field of gearbox production testing, the gearbox high-speed-level vibration mode testing device comprises a testing table, the testing table is arranged to be a horizontal workbench, a linear sliding groove of a linear structure is formed below a testing opening, a sliding seat is slidably connected in the linear sliding groove, and the sliding seat is arranged in the testing opening. A gear box is installed at the top end of the sliding seat and horizontally slides in the testing opening through a linear sliding groove. The testing port is of a semicircular arch structure, a gear box is convenient to install and easy to automatically move, a linear sliding groove of a linear structure is formed below the testing port, a sliding seat is slidably connected into the linear sliding groove, the gear box is installed at the top end of the sliding seat, and the gear box horizontally slides in the testing port through the linear sliding groove. Axial reciprocating sliding of the gear box can be achieved through the linear sliding groove, and receding can be conveniently conducted in the mounting and dismounting process.
