Abstract
The utility model discloses a large-sized rotor static balancing device which comprises a rotor, a rotor connecting shaft, a bearing pedestal and a bracket. The rotor connecting shaft is fixedly arranged on a rotor axial center; two ends of the rotor connecting shaft are arranged on the bearing pedestal and just can rotate around the axial center relatively to the bearing pedestal; the bearing pedestal is arranged on the bracket, and the circumferential end face of the rotor is uniformly divided into sixteen equivalent parts and marked; a connecting drawn wire is connected on the rotor around the circumferential direction, and a standard counterweight block is arranged at one end of the connecting drawn wire and a pull tension gauge is arranged at the other end of the connecting drawn wire; and the standard counterweight block and the pull tension gauge do not contact with the outer circumferential face of the rotor. The device not only has a simple structure, but also can greatly save labor and time.
Description
Technical field
The utility model relates to a kind of large rotor and does static balancing apparatus.
Background technology
At present, doing large-scale rigidity rotor balancing does not have special-purpose transient equilibrium equipment, can only take the static equilibrium method.Balancing method generally can only be leaned on rotor repeatedly; Come the rough maximum uneven point of finding out; Sensation according to the technician constantly increases and decreases equilibrate counterweight then, seeks next uneven point more successively, finally can stop in the arbitrfary point and no longer revolution until rotary rotor.This method, not only operation is loaded down with trivial details, and time and effort consuming.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of large rotor to do static balancing apparatus, and this device is not only simple in structure, and can save manpower and time greatly.
The utility model for the technical scheme that solves its technical matters and adopt is: a kind of large rotor is done static balancing apparatus, comprises rotor, rotor coupling shaft, bearing seat and support, and said rotor coupling shaft is fixedly arranged on the said rotor axis; The two ends of said rotor coupling shaft are located on the said bearing seat, and said rotor coupling shaft just can rotate around its axle center by said relatively bearing seat; Said bearing seat is located on the said support, and said rotor circumference end face is divided into some even number equal portions and mark in equal size; On said rotor, be provided with one around its circumferencial direction and connect wire drawing, an end of this connection wire drawing is provided with the standard balancing weight, and the other end is provided with tautness meter, and said standard balancing weight and tautness meter do not contact with said rotor outer peripheral face.During use, elder generation is divided into the circumferential end surfaces of rotor as if an even number equal portions and makes clear marking, and (or certain a pair of 2 suitable equal portions point places on the vertical direction respectively to make certain a pair of 2 relative equal portions point place horizontal level respectively simultaneously; Be the highs and lows place of rotor), place on the rotor outer peripheral face connecting wire drawing then, an end that connects wire drawing connects a standard balancing weight; Like 10Kg, the other end that connects wire drawing is a tautness meter, treat rotor balancing after; Read the tautness meter registration, can judge the equilibrium condition at a pair of equal portions point place that is in horizontal direction on the rotor and make record according to this registration, and then successively other reading records that equal portions point is placed horizontal level respectively and makes tautness meter; Find out the maximum differential value of suitable 2 equal portions points at last, and carry out counterweight and replenish, promptly increase welding rod in the lightest position; Come balancing rotor; So, can repeatedly repeat the inspection and the effect of balance, very easy to use.
As the further improvement of the utility model, between said bearing seat and support, also be provided with the adjusting jackscrew, this regulates the height of jackscrew adjustable axle bearing.
Preferably, said rotor is divided into 16 equal portions in equal size.
The beneficial effect of the utility model is: through being divided into the rotor circumference end face some even number equal portions and making a mark, place on the rotor circumference face connecting wire drawing then, a pair of suitable two equal portions point of rotor is laid respectively on the horizontal direction; The two ends that connect wire drawing connect standard balancing weight and tautness meter respectively; Can judge the equilibrium state of 2 equal portions points of rotor horizontal direction through the registration of tautness meter, then and the like, can check other equilibrium conditions respectively to equal portions point; Can make indemnifying measure according to the check structure at last; This device is not only simple in structure, and very easy to use, can save manpower and time greatly.This balance can reach more than the G6.3 level of " GB 9239-1988 balance quality of rigid rotor is allowable unbalanced definite ", can satisfy various balance requirements.This device can the large-scale outside diameter 2m-5.3m of convenient and swift accurate realization rigidity rotor static balancing, is applicable to the interior rigidity rotor of supporting powder concentrators, fan rotors such as Vertical Mill, pipe mill.
