Body, when placing revolving body can by fixed pin be inserted into rolling ring in case rolling ring roll.Rolling is plugged when measurement period
Handle is changed hands to facilitate rotation rolling ring to certain angle, the preload block locking on retaining mechanism is recycled, rolling handle is removed.
After ER equipment ready, release lever is freed in release, makes rolling ring free rolling on idler wheel, under the action of the spring, steel band
It drives rolling ring to do period rolling, to drive revolving body rolling movement in the axial direction, realizes corresponding test job.
Polar moment of inertia test equipment can test the polar moment of inertia of medium-sized and large-scale diameter revolving body, and rolling system can be solely
Vertical work, respectively comes with the mechanisms such as spring, steel band, decelerating motor, sensor.The preceding most important component of rolling system is a rolling
Ring two idler wheels can free rolling, two surveys of rolling ring are equipped with steel band, and steel band is connected with driving of the spring as period rolling
Power.Rolling ring is three annulus, unclamps the screw at top and can open, the ring on rolling ring both sides can be placed on two surveys after opening
In rolling ring placement block.The cushion block of different-thickness can be installed to adapt to the body of different-diameter in rolling ring, rolling ring is beneath, and there are two solid
Rationed marketing, when placing revolving body can by fixed pin be inserted into rolling ring in case rolling ring roll.A rolling can be plugged in rolling ring
Handle, effect are that rolling handle is plugged when measurement period to facilitate rotation rolling ring to certain angle, then with freeing
The preload block of relieving mechanism locks rolling ring, i.e., so that rolling is in pre- pendulum state, rolling handle is after rolling ring is in pre- pendulum state
It should remove.It can give rolling ring one pretightning force by rolling handle, be locked using the preload block on retaining mechanism after reaching designated position
Tightly, after ER equipment ready, release lever is freed in release makes rolling ring drive revolving body rolling movement in the axial direction, realizes corresponding
Test job.Rotation mechanism for wind is mounted on connecting plate, and connecting plate is connect by support column with fixed plate, and fixed plate is mounted on test
In equipment.
Invention has the beneficial effects that：The invention mechanism effectively improves test effect, convenient preferably according to need
It to be tested for polar moment of inertia, it is easy to use.
