[0002] At present, variable speed clutch transmission devices are widely used in BPRT units and SHRT units in the metallurgical and petrochemical industries. BPRT units and SHRT units are blast furnace energy recovery units with blast furnace gas waste heat and waste pressure turbine power generation devices and blast furnace blower coaxial systems developed based on the needs of users in the metallurgical and petrochemical industries, and have good energy-saving effects. Through BPRT or SHRT units, not only can the pressure energy and heat energy of blast furnace gas be recovered, and the flow noise of the gas transmission network be reduced, but also the blast furnace top pressure, axial flow fan, and gas turbine can be highly intelligently controlled to improve the smelting intensity and output of the blast furnace. The use of BPRT and SHRT systems not only recovers the energy wasted by the previous pressure reducing valve group, but also reduces the amount of waste gas emissions and further improves energy utilization efficiency.

[0003] The variable speed clutch transmission device is a key component of the BPRT unit and the SHRT unit. The unit is arranged in the form of turbine-variable speed clutch transmission device-blower-variable speed gearbox-motor. The unit realizes online automatic engagement and online automatic disengagement of the turbine unit and the blower unit through the variable speed clutch device, realizing energy recovery of sintering waste heat and blast furnace waste pressure.

[0004] At present, when the speed-changing clutch transmission device is undergoing factory dynamic testing, the input and output speeds of the transmission device need to be precisely controlled to simulate the clutch engagement and disengagement states under actual working conditions. During the test, the speed, bearing temperature, and vibration values ​​of the speed-changing clutch transmission device need to be fully monitored. The values ​​of these parameters under actual working conditions are of great significance for evaluating the working performance of the speed-changing clutch device. Summary of the invention

The purpose is to accurately control the clutch input and output speeds when performing a dynamic test on the speed-changing clutch transmission device, simulate the clutch engagement and disengagement states under actual working conditions, and provide reliable support for the working performance of the speed-changing clutch device under actual working conditions.

[0006] A dynamic test system for a variable speed clutch transmission device comprises an input side motor, an input side test gearbox, an output side test gearbox and an output side motor, wherein the input side motor is connected to the input side test gearbox via a diaphragm coupling, the input side test gearbox is connected to the output side test gearbox via a diaphragm coupling and an existing variable speed clutch transmission device, and the output side test gearbox is connected to the output side motor via a diaphragm coupling.

[0007] Furthermore, a bearing temperature sensor 1 is installed on the front bearing box of the input side gearwheel of the speed change clutch transmission device, and a bearing temperature sensor 2 is installed on the rear bearing box of the input side gearwheel.

[0008] Furthermore, a bearing temperature sensor 3 is installed on the front bearing box of the output side pinion of the speed change clutch transmission device, and a bearing temperature sensor 4 is installed on the rear bearing box of the output side pinion.

[0009] Furthermore, a bearing temperature sensor five is installed on the front bearing box of the output shaft of the speed-changing clutch transmission device, and a bearing temperature sensor six is ​​installed on the rear bearing box of the output shaft.

[0012] Furthermore, a vibration sensor five and a vibration sensor six are installed on the output shaft of the speed change clutch transmission device.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The variable speed clutch transmission dynamic test bench simulates the actual use conditions of the equipment on site. The input side motor and the input side test gearbox simulate the input speed of the variable speed clutch transmission turbine unit, and the output side motor and the output side test gearbox simulate the output speed of the variable speed clutch transmission fan. By controlling the speed of the motors on both sides, the speed difference between the input and output sides of the clutch of the variable speed clutch transmission is achieved, and then the clutch engagement and disengagement at different speeds are tested.

[0015] Under different speeds and different clutch engagement and disengagement states, the temperature of the large gear, small gear and output shaft bearings of the speed change clutch transmission device is monitored in real time; the vibration displacement of the large gear shaft, small gear shaft and output shaft of the speed change clutch transmission device is monitored in real time, and the clutch disengagement state is monitored in real time.
