Description
Technical field
The present invention relates to a kind of digital Revolving body static balancing measurement apparatus and measuring method, belong to technology of rotary body detection
Field.
Background technology
The object having many rotations needs to do static balance, particularly the rotary bodies such as the emery wheel of high-speed rotation, impeller, belt wheel.
By the control to object static balance value, it is ensured that object vibration caused when rotating is in certain allowed band.
At present, balancer used by Revolving body static balancing for the measurement mainly has beam barrel type, thimble-type, steel-ball type.Beam barrel type is put down
Weighing apparatus is by balancing axle and supporter forms, and supporter is usually two and is parallel to each other and the cylindrical rod of level or double inclined plane guide rail,
Also can be two to round steel dish overlapped and free to rotate.Thimble-type balancer is made up of thimble, pallet；Steel-ball type is put down
Weighing apparatus is made up of steel ball, pallet.
For beam barrel type balancer, during use, balance axle is passed through the centre bore of object, make the plane of object at peace
The vertical position of weighing apparatus axle axis.Then it is placed on balance axle on balancer supporter, make the balance axle equipped with object freely rotatable,
When object reaches equilbrium position, its barycenter is in lowest part.By adding suitable counterweight at the peak of object balance state,
Being allowed to all reach balance in any position, now the quality of counterweight is exactly object amount of unbalance inherently.
For thimble-type balancer, steel-ball type balancer, as long as being placed on pallet object, the centre bore of object passes through torr
Locating shaft on dish.If mass of object is uneven, it can tilt to the direction laid particular stress on.By at incline direction relative to high point
Add suitable counterweight, be allowed to balance.Weight mass now is exactly object amount of unbalance inherently.
Existing static balance measuring method has the disadvantage that：
（1）Precision is low.For the static balance measuring method using beam barrel type balancer, its precision is by the shadow of method of operating error
Ringing, precision typically can only achieve 160gmm；It is commonly used in grinding wheel cylindrical week stickup plasticine or flexible strip is stuck in grinding wheel cylindrical
The method measurement in week, measurement position do not fixes, and big especially for diameter, thickness is thick, the emery wheel of Heavy Weight, measured value artificially misses
Difference is big, and precision is low.Using the static balance measuring method of thimble-type or steel-ball type static balancing device, its precision is by thimble, steel ball and torr
The impact of dish cooperation, pallet locating shaft and object centre bore quality of fit, precision is lower.In view of easy to operate, pallet positions
Axle and object centre bore typically use matched in clearance, and the object to diameter 200mm weight 1000g for the gap of 0.1mm, in limit feelings
The measure error producing under condition just can reach 1g, adds the error that thimble, steel ball and pallet produce, and composition error can reach 2g
Above；
（2）Poor repeatability.The difference of each rigging position all can cause the change of object static balance measured value, it is impossible to determines object
Unbalanced exact value, particularly during the measurement big emery wheel of weight, its repeatability is worse；
（3）Unbalanced value can not direct digital display.Existing method is all to add counterweight to measure imbalance, and counterweight needs repeatedly to adjust
Whole；
（4）Top formula or steel-ball type static balance measuring method may be only available for lighter object.
