Specific work process is as follows：
First, it installs in wheel hub 23 to clamping device 24：
1. loosering a bolt, loosen three pieces of grip blocks, mobile clamping block holds position until that can be put into wheel hub 23；
2. hand rolled round, screw rod 22 rises, and band runner hub pallet 21 rises to suitable position in order to 21 support of wheel hub pallet
Play wheel hub 23；
3. after being put into wheel hub 23, mobile clamping block is held to be fitted closely with the tire contact plane of wheel hub 23, pre-screwing clamping
Block is held, and pre-screwing clamping block again reinstalls the grip block pre-screwing loosened after holding；

Cheng Zhong, wheel hub 23 suffer from one's own actions the certainly heart on clamping wheel hub pawl 18；
5. hand rolled round, band runner hub pallet 21 is detached from wheel hub 23；
6. grip block is tightened in interaction and clamping block is held.
There are many forms for the moulding of wheel hub 23, and the shape that clamping block is held is the parameter provided according to 23 provider of wheel hub
Come what is manufactured, ensure that the shape held of clamping block and the shape of wheel hub 23 fit closely, wheel hub 23 being capable of stress during actual test
Uniformly.
2nd, wheel hub is tested by alternation tangential stress：
After 1. motor 1 is run, the retarder 2 is driven to operate, retarder 2 drives sheave 3 to rotate, due to sheave 3
The center of circle and the output of retarder 2 axle center are misaligned, when sheave 3 rotates, form a kind of running orbit of off-centre operation.First rolling
