Abstract
The utility model relates to a high-speed dynamic balance device of slender flexible rotor, which is characterized in comprising two semicircle balance snap rings that have threaded holes; Threaded holes are uniformly distributed on circumference of the balance clasp; balance weight screw can be fixed in the threaded hole; the outer surface of the balance clasp symmetric polygon, both side of the outer surface has a tightening bolt hole; the two semicircle balance clasps and the rotating shaft are fit tightly by a plurality of fastening bolts and a plurality of screw caps. The utility model has the advantages of novel design, simple structure, safe and reliable use, and convenient operation. The unbalance value of rotor on the position of balancing device can be determined accurately. The utility model can be made to various specifications according to the size of the rotating shaft. The balancing device of the same rotating shaft can be used repeatedly. When the utility model is used in high-speed dynamic balancing test, the utility model has the advantages of high balance precision, high efficiency; meanwhile, the utility model can satisfy the precision high dynamic balance of high-speed slender flexible rotor.
Description
Technical field
The utility model belongs to a kind of firm or fixing device of formation or machine parts, particularly relates to a kind of elongated flexible rotor high-speed dynamic poise device.
Background technique
Along with development of science and technology, the slenderness ratio of elongated flexible rotor is increasing, generally all works under supercritical speed, and the vibration that causes owing to rotor unbalance during rotation is very big.In order to solve the elongated flexible rotor because uneven caused vibration problem, often all must carry out the high-speed balancing test to rotor, at the trial by directly adding counterweight on the rotor or on rotor, removing the part material, to reach the rotor purpose of balance when rotated, but must reserve the member that adds counterweight in the rotating shaft, the diameter of rotating shaft just needs the bigger of design like this.
Summary of the invention
The purpose of this utility model is to solve the elongated flexible rotor can't directly add test mass on axle when high-speed balancing is tested a difficult problem, provides a kind of simple in structure, easy to use, finds the Equilibrator of amount of unbalance size and phase place fast.
Main feature of the present utility model is two the semicircle balance snap rings formations of described Equilibrator for the band central shaft hole, is evenly equipped with tapped hole on the circumference of its balance snap ring, can counterweight screws be set according to the size and the phase place of amount of unbalance in the tapped hole; The outer surface of described two semicircle balance snap rings is symmetrical polygonal, respectively is provided with a clamping bolt hole on the both sides of outer surface, and clamping bolt, nut are with two semicircle balance snap rings and rotating shaft drive fit.
The utility model has the advantages that modern design, simple in structure, safe and reliable, easy to operate, the axle that can accurately determine rotor is gone up size and the phase place at the amount of unbalance that the Equilibrator position is installed.Add counterweight screws by uniform tapped hole on the balance snap ring circumference.According to the size of rotating shaft, can make all size, the Equilibrator of same rotating shaft can be reused.When adopting this Equilibrator to carry out the high-speed balancing test, the balance quality height, the efficient height can satisfy the dynamically balanced needs of high rotating speed elongated flexible rotor high speed and precision.

Embodiment
As seen from Figure 1, the utility model is to be made of two semicircle balance snap rings 1 being with central shaft hole 5, is evenly equipped with tapped hole 4 on the circumference of balance snap ring 1; The outer surface of two semicircle balance snap rings 1 is symmetrical polygonal, respectively is provided with a clamping bolt hole on the both sides of outer surface, clamping bolt 2, and nut 3 closely is fixed tightly in two semicircle balance snap rings 1 with rotating shaft.The elongated flexible rotor is being done high-speed balancing when test with 1 rotation of balance snap ring, thereby finds out on the rotor size and phase place at the amount of unbalance that the Equilibrator position is installed.Add counterweight screws 6 just can realize the adding an examination of purpose of counterweight and counterweight by tapped hole 4 uniform on balance snap ring 1 circumference, need not to reserve the member add counterweight on the axle of rotor, the axle of directly finding out rotor is gone up size and the phase place at the amount of unbalance that the Equilibrator position is installed.
Claims (2)
1, a kind of elongated flexible rotor high-speed dynamic poise device is characterized in that: described Equilibrator is evenly equipped with tapped hole (4) for two semicircle balance snap rings (1) of band central shaft hole (5) constitute on the circumference of two balance snap ring (1); In the described tapped hole (4) counterweight screws (6) can be set.
