Abstract
The invention provides a dynamic balance adjusting device for a roll shaft. The dynamic balance adjusting device comprises a counterweight ring sleeved on the roll shaft, and a cylindrical cavity radially arranged on the counterweight ring. A rod-free piston is arranged in the cylindrical cavity, a water injection passage is arranged at one end of the cylindrical cavity, the water injection passage is communicated with the water injection port arranged on the outer surface of the counterweight ring, a water valve is arranged on the water injection port, the water injection passage side of the rod-free piston is filled with water, and the non-water-injection passage side of the rod-free piston is filled with air. Water is used as a counterweight, weight of the counterweight can be adjusted infinitely, and accordingly a dynamic balance index of the roll shaft is more accurate.
Description
Technical field
The present invention relates to transient equilibrium and adjust apparatus field, especially, is a kind of roll shaft dynamic balance adjusting apparatus.
Background technology
Comprise a large amount of parts that rotate in the conventional machinery, such as rotor of various transmission shafts, main shaft, motor and steam turbine etc., be referred to as solid of revolution.The pressure that bearing is produced is the same when not rotating solid of revolution when rotation in ideal conditions, and such solid of revolution is the solid of revolution of balance.But the various solid of revolution in the engineering, because the error that produces in the inhomogeneous or blank defective of material, processing and the assembling, even when design just have the many factors such as asymmetrical geometric configuration so that solid of revolution is when rotated, the centrifugal intertia force of each small particle generation can not be cancelled out each other it on, centrifugal intertia force is applied on machinery and the basis thereof by bearing, cause vibration, produced noise, accelerate bearing wear, shorten mechanical life, can damage incidents when serious.For this reason, must make its balance accuracy grade that reaches permission to balancing rotor, or make so the mechanical vibration amplitude that produces is fallen in allowed limits.
The physical construction of commonly using in the textile machine is the machinery that the roll shaft classes such as all kinds of roll shafts, roller, deflector roll, roller, brush roll form, textile machine is when operation, fast or the slow operation of these roll shaft classes roll shaft mechanically, the rotation of roll shaft must bring wearing and tearing, brush roll particularly, brush roll can be along with the passing of service time, its surperficial hairbrush weight is with serious skewness, produce serious vibrations in the time of can causing the brush roll rotation, this vibrations not only affect the effect of the product of producing, and have accelerated the aging of machinery.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of roll shaft dynamic balance adjusting apparatus, this roll shaft effectively solves the vibrations that roll shaft produces because of wearing and tearing with dynamic balance adjusting apparatus.
The technical solution adopted for the present invention to solve the technical problems is:
This roll shaft comprises counterweight ring with dynamic balance adjusting apparatus, and described counterweight ring is socketed on the described roll shaft, is evenly equipped with the counterweight chamber around described counterweight ring center in the described counterweight ring, and described counterweight chamber comprises the passage of putting into mass.
As preferably, the cylindrical chamber of described counterweight chamber for radially arranging with described counterweight ring, be provided with rodless piston in the described cylindrical chamber, described cylindrical chamber one end is provided with waterflood path, described waterflood path is communicated with the water filling port that is arranged on described counterweight ring outside surface, be provided with water valve on the described water filling port, described rodless piston has the waterflood path side to be full of water, and described rodless piston is full of air without the waterflood path side.
Use liquid water as mass, the weight of adjustment mass that can be electrodeless, after increase was adjusted, the transient equilibrium index of roll shaft was better.
As preferably, described cylindrical chamber has transparent windows at described counterweight ring, and at described view window the water filling scale is set, and the handled easily person precisely adjusts counterweight.
The invention has the advantages that:
1. by at described roll shaft counterweight ring being set, can reduce or eliminate the vibrations that roll shaft produces because of wearing and tearing
2. adopt water as mass, the weight of adjustment mass that can be electrodeless makes the transient equilibrium index of roll shaft more accurate.
