It is fixedly mounted on the experiment arm of force；The end of the main shaft and flanged ends is also fixedly connected with flange plate.
The pressure exerting arrangement is the opposite hydraulic cylinder a and hydraulic cylinder b of active force, and the two is separately positioned on the two of base platform
End, hydraulic cylinder a and hydraulic cylinder b are correspondingly arranged on pressure sensor a and pressure sensor b respectively, hydraulic cylinder a and hydraulic cylinder b's
Both ends of the force application part respectively with the experiment arm of force are fixed.
Compared with prior art, the beneficial effects of the invention are as follows：The utility model wind-driven generator simulation group is using lock
Special test platform is made using hydraulic force arm load mode in operating mode when tight disk, is detected to the transmission torque of locking plate；
The arm of force is equivalent to fan blade, and one end of main shaft connects the arm of force, and the other end of main shaft is set with axle sleeve and forms circumference frictional fit,
By the way that main shaft and flange to be keyed, then flange flange is added in flange body, flange flange disk is by passing through several
The fixing bolt of equal angle setting is fixedly mounted on the experiment arm of force, when increasing flange and testing arm of force cooperation by force
Arm, stability when the two being made to coordinate greatly improve.Locking plate is mounted on axle sleeve, after locking plate, which assembles, locks, makes axle sleeve
Normal pressure is generated between main shaft, and the data for transmitting torque are can detect that when the load of the hydraulic cylinder at arm of force both ends.The experiment
Platform is reasonable for structure, easy to operate, and small investment is at low cost, and test period is short, and test site is small.Although the utility model structure ratio
It is relatively simple, but solve under major diameter state locking plate to the test problem of the stability maintenance of shaft sleeve of fan.
