Description
Technical field
The utility model relates to paper machine technology field, is specifically related to a kind of minor diameter High Rotation Speed roll body dynamic poise device.
Background technology
Papermaking equipment is made up of the roller rotated in a large number, and manufactures in the process of roller, and roller quality distribution is inconsistent can produce extra bending load and swing load, namely uneven.Roll body produces roll body circumference quality when welding uneven, the shrinkage cavity that foundry goods produces, imbalance when cumulative errors cause the factor such as uneven of roll body wall thickness that roll body all can be caused to rotate in process thus cause nuisance vibration.Because imbalance can produce centrifugal force when roller rotates, and there is proportionate relationship between this centrifugal force and speed, when roll body High Rotation Speed, even if there is very little imbalance, also can produce very large centrifugal force.
Traditional dynamic balance method is two sections of transient equilibrium, is to add counterweight at roll body two ends to balance laying particular stress on of roll body, and its theoretical foundation is hypothesis roll body is rigidity, and laying particular stress on different section can be cancelled out each other.
Along with improving constantly of paper machine fabric width in recent years and the speed of a motor vehicle, the rotational speed of partial roller has exceeded its critical rotary speed, and now roller just can not regard the rotor of a rigidity again as.Two sections of traditional balance methods cannot overcome the Dynamic flexural distortion of roll body.Though there are two kinds of inside to add the structure of three sections of balances of counterbalance weight at present, for some as carrier drum, at a high speed (more than speed of a motor vehicle 2000m/min), the roller of minor diameter, all can not be suitable for winding roll etc.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of minor diameter High Rotation Speed roll body dynamic poise device, can be used for more than speed of a motor vehicle 2000m/min, is applicable to the roll body of diameter range 300mm ~ 600mm.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of minor diameter High Rotation Speed roll body dynamic poise device, comprise bracing frame 1, spring 2, interior pipe 3 and pin 4, interior pipe 3 there is the hole that two row's circumferences are uniform, bracing frame 1 is provided with round tube, round tube inserts to be put in the uniform hole of interior pipe 3 circumference and fixes with pin 4, spring 2 is installed on described round tube, and one end of spring 2 withstands on bracing frame 1, and the other end withstands on interior pipe 3 outer wall.
Support frame as described above 1 there is the U-lag installing balancing component.
The beneficial effects of the utility model are: the flexible deformation that effectively can eliminate roll body, make minor diameter roll body rotate steadily at high speeds, reduce the failure rate of paper machine operation, simple and reliable for structure, be applicable to more than speed of a motor vehicle 2000m/min, diameter is at the roll body of 300mm ~ 600mm.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As depicted in figs. 1 and 2, a kind of minor diameter High Rotation Speed roll body dynamic poise device, comprise bracing frame 1, spring 2, interior pipe 3 and pin 4, interior pipe 3 there is the hole that two row's circumferences are uniform, bracing frame 1 is provided with round tube, and round tube inserts to be put in the uniform hole of interior pipe 3 circumference and fixes with pin 4, and spring 2 is installed on described round tube, one end of spring 2 withstands on bracing frame 1, and the other end withstands on interior pipe 3 outer wall.Bracing frame 1 there is the U-lag installing balancing component.
Principle of work of the present utility model is:
With reference to Fig. 3, the cross sectional shape of haltere 5 is hexagons, prevents own rotation.Under the effect of pin 4, the external diameter of balance device is less than the internal diameter of roll body 6, at this moment, balance device is loaded roll body 6 centre position, and take off pin 4 from balance device, under the effect of spring 2, bracing frame 1 on balance device just withstands on roll body inwall, when roll body rotates, balance device rotates with roll body by the friction force between bracing frame 1 with roller inwall, when roll body does transient equilibrium, if the middle dynamic deflection value of the roll body measured 6 exceeds designing requirement, equilibrator can go out weight and the phase value of counterbalance weight according to dynamic deflection size primary Calculation.Now, by the haltere 5 of certain length, from the hole that roll body 6 two ends silently, according to the phase mark previously made, haltere 6 is contained in the U-lag on bracing frame 1, then transient equilibrium is done, measure roll body 6 dynamic deflection, if dynamic deflection does not also reach designing requirement, take out haltere 5 from balance device, utilize the correction numerical value of equilibrator, readjust the length of haltere 5, repeat above-mentioned haltere installation process again, again do dynamic balance running, until the dynamic deflection of roll body 6 reaches designing requirement.
