Abstract

The invention relates to a low-speed shaft brake energy-efficiency test board and a test method thereof. The low-speed shaft brake energy-efficiency test board comprises a base, wherein a variable-frequency driving motor is fixedly installed on the base, one end of the variable-frequency driving motor is connected with a rotating coder, the other end of the variable-frequency driving motor is provided with a front-section main shaft by virtue of a first coupler, the front-section main shaft is provided with a main shaft bearing, a main shaft brake disc and a plurality of inertia discs, the end socket of the front-section main shaft is connected with a rear-section main shaft by virtue of a second coupler, a plurality of inertia discs are also installed on the rear-section main shaft, a tail portion of the rear-section main shaft is provided with a brake mating part, and the rear end of the brake mating part is provided with a brake mating part replacing apparatus; and the base is also provided with an inertia disc control apparatus for controlling the connection and disconnection of the inertia discs. By adopting the low-speed shaft brake energy-efficiency test board, the application flexibility is improved, and the working reliability and convenience are improved.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery equipment, in particular to a low-speed shaft brake energy efficiency test bench and a test method thereof. Background technique [0002] The brake inertia test bench is mainly composed of a drive motor, a main shaft, an inertia disk, a reducer, and a support bearing. The inertia disk is large in size and heavy in weight, and the maximum weight can reach 1.8 tons. When testing brakes with different braking torques, it is necessary to calculate the moment of inertia that needs to be loaded according to the magnitude of the braking torque. The inertia discs have different moments of inertia. According to the calculated total inertia, make an appropriate combination to determine which inertia discs are connected to the rotation. The main shaft, which inertia disk needs to be disengaged from the rotating main shaft. It is impossible to manually load and disengage such a heavy inertia disc...
