Specific implementation mode
The utility model is furtherd elucidate below in conjunction with the accompanying drawings.
As shown in Figure 1, the seat of the application falls endurance test equipment, including falling device, seat fixed plate 1 and counting
Device 2, falling device include driving device 3, balance wheel 4, bearing 5 and mandril 6, and seat fixed plate 1 is arranged in 6 upper end of mandril, and lower end connects
It is connected to bearing 5, balance wheel 4 is located at the lower section of bearing 5, and driving device 3 is sequentially connected with balance wheel 4 and balance wheel 4 is driven to rotate, balance wheel 4
For sickle shaped.Counter 2 is connect with balance wheel 4, after balance wheel 4 drives mandril 6 to move upwards, 6 free-electron model of mandril.
Driving device 3 includes motor 31 and speed reducer 32, and motor 31 is connect with speed reducer 32, and speed reducer 32 connects with balance wheel 4
It connects.Balance wheel 4 is directly installed on the output shaft of speed reducer 32.Or between balance wheel 4 and speed reducer 32 be chain drive, speed reducer 32
Output shaft on be provided with drive sprocket, there is driven sprocket, drive sprocket to pass through chain with driven sprocket by axis connection on balance wheel 4
Item connects.
Holder 8 supports workbench 7, and seat fixed plate 1 is located at 7 top of workbench, and mandril 6 is arranged across workbench 7, drives
Dynamic device 3 and counter 2 are arranged on holder 8.It is socketed with casing 10 outside mandril 6, through-hole, casing are provided on workbench 7
10 are fixed in the through-hole of workbench 7.
The position for being located at 1 lower section of seat fixed plate on the table 7 is provided with silencing block 11 and buffer stopper 12.Silencing block 11
It is wrapped in 12 periphery of buffer stopper, buffer stopper 12 is made of rubber material, prevents seat fixed plate 1 from being connect with the directly rigidity of workbench 7
It touches, periphery of the silencing block 11 in addition to being wrapped in buffer stopper 12, can also be separately provided on the table 7, be spaced with buffer stopper 12
Setting, silencing block 11 are made of quieter material, and quieter material is silencing cotton or butyl rubber.
