Detailed Embodiment

Among them, the low-pressure stage drive motor 1 is connected to the reversing gearbox 2, and the reversing gearbox 2 is connected to the high-pressure stage middle fulcrum 4, both are installed on the product mounting bracket 3; the high-pressure stage middle fulcrum 4 is connected to the speed increasing gearbox 5, and the speed increasing gearbox 5 is connected to the main driving motor 7 through the coupling 6, and the main driving motor 7 is installed on the motor support base 13; the loading motor 8 is connected to the hydraulic pump load gearbox 9, one end of the adapter sleeve 11 is connected to the AC motor load gearbox 10, and the other end is connected to the constant speed drive motor 12. Particularly, it relates to a mechanical system of an aviation transmission system test bench, which is characterized by including: low-pressure stage drive motor, reversing gearbox, product mounting bracket, high-pressure stage middle fulcrum, speed increasing gearbox, coupling, main driving motor, loading motor, hydraulic pump load gearbox, AC motor load gearbox, adapter sleeve, constant speed drive motor, and motor support base. Among them, the product is fixed on the product mounting bracket; the adapter sleeve is installed on the product; one end of the hydraulic pump load gearbox is connected to the adapter sleeve and the other end is connected to the loading motor; one end of the AC motor load gearbox is connected to the adapter sleeve and the other end is connected to the loading motor; the constant speed drive motor is connected to the adapter sleeve; the main driving motor is installed on the support base and drives the speed increasing gearbox through the coupling; the speed increasing gearbox is connected to the high-pressure stage middle stop point and drives one transmission chain of the product; the low-pressure stage drive motor is connected to the reversing gearbox and drives another transmission chain of the product. The mechanical system has three drive systems. Different drive parts can be controlled separately, which is more conducive to maintenance and repair. Both the AC motor load gearbox and the hydraulic pump load gearbox are movable gearboxes. The movable gearbox has more advantages compared to the fixed gearbox and can meet the usage requirements of different operations. It can test three products, namely the front drive engine case, the central drive engine case, and the rear drive engine case, at the same time. It improves work efficiency and saves test costs. The front drive engine case, the central drive engine case, and the rear drive engine case are all fixed on the product mounting bracket. The coaxiality between the main driving motor and the speed increasing gearbox can be adjusted by increasing or decreasing the adjustment pads between the main driving motor and the motor support base. The design of the adjustment pads can make a fine adjustment to the coaxiality, so that the coaxiality between the main driving motor and the speed increasing gearbox can achieve a better match. The engine case is connected to the loading motor through the adapter sleeve. The adapter sleeve can be various to meet the docking operations between different engine cases and the loading motor. The high-pressure stage middle stop point adjusts the distance between the speed increasing gearbox and the central drive engine case. The distance between the speed increasing gearbox and the central drive engine case can be better guaranteed. The speed of the main driving motor is increased through the speed increasing gearbox. By increasing the speed, the rotational speed of the main driving motor can meet higher requirements. The three drive systems can be started simultaneously and operate synchronously at a certain proportional rate.When the three drive systems start working simultaneously, it can save test time and improve test efficiency. The movable gearbox moves along the guide rail of the vehicle platform itself and plays a positioning role. The movable gearbox is movable, meeting the requirements of different working conditions, and is firmly fixed, solving the problem of inconvenient operation of the fixed gearbox. The front drive engine case, the central drive engine case, and the rear drive engine case are respectively installed on the product mounting rack. The main drive motor, the low-pressure stage drive motor, and the constant speed drive motor realize the operation of the drive system, and the loading motor realizes the test loading function.
