Abstract
The vibration damper for spinning jet of glass fibre of the utility model is an improvement of spinning jet of continuous glass fibre, adopting a plurality of elastic damping vibrators to separate a bearing seat of a spinning jet rotating member of glass fibre wire-drawing from a framework in order to damping vibrations. The elastic vibration dampers comprise spring vibration dampers and rubber vibration dampers. The utility model takes the spring vibration dampers as the main damping element with a damping and a setting element which are composed of the rubber vibration dampers. The utility model can cause the glass fibre wire-drawing to work steadily, to reduce vibrations and noises, to improve the work condition of labors and to prolong the service life of the spinning jet.
Description
Glass fiber wire-drawing machine head vibration-control system is a kind of improvement of producing the wire-drawing machine head of continuous glass fibre.
Wire-drawing machine head is the major parts of glass fiber wire-drawing machine, it is a kind of high speed rotary spare, owing to occur the mass eccentricity of self in the manufacturing processed inevitably, it is irregular to add the bobbins mass distribution, reason such as positioning error during sleeve, always there is quiet, unbalance dynamic inevitably in the rotating part of head.Because unbalanced existence will encourage head to do forced vibration.Used wire-drawing machine head is to adopt rubber ring that bearing support and frame are separated, in the hope of vibration damping.But often do not reach the effectiveness in vibration suppression of the phase of giving merely with this rubber ring, simultaneously owing to high-frequency alternate strain, rubber ring is very fast aging, and physical properties changes, thereby makes effectiveness in vibration suppression poorer.
Task of the present utility model provides a kind of vibration-control system.This device is to adopt plurality of elastic vibration damping that the bearing support and the frame of wire-drawing machine head revolving meber are separated, to reach the purpose of vibration damping.Elastic damping comprises spring damping and rubber damping, is main damping element with spring damping, is aided with rubber damping and is damping and setting element.
Device of the present utility model such as accompanying drawing (1).
This device is made up of frame (1), main shaft (2), bearing (3), bearing block (4), aluminium rotating cylinder (5), rubber damping (7), retainer plate (8) and spring damping (9) etc. Elastic damping all is contained in the outside of bearing block (4), with spring damping of the vibration damping of deciding along bearing block 1-6 group axially can be housed, every group has 3-15 along the bearing block arranged radially, such as accompanying drawing (2). The diameter of spring wire is the 0.8-2.8 millimeter, and spring damping can be Compress Spring, also can be sheet spring or leaf spring, such as accompanying drawing (3). The wire such as the available spring steel of spring damping, stainless steel, bronze or sheet metal are made. Rubber damping also is contained in the outside of bearing block (4), along bearing block 1-6 group is housed axially, has 3-15 along the bearing block arranged radially in every group, plays damping and positioning action. Rubber damping can be the column of various cross sectional shapes, except making of rubber, also can make of engineering plastics. Every group of rubber damping also can be replaced by rubber ring.
The utility model has the advantages that and adopted the spring damping damping element of deciding that the bearing support and the frame of wire-drawing machine head solid of revolution separated, because the mechanics quality stable of spring, good damping result, make the drawing wire machine running steadily, reduce vibration and noise, improve workman's operating environment, improved the work-ing life of head.
Embodiment of the present utility model is shown in accompanying drawing (1), main shaft (2) is linked together with aluminium rotating cylinder (5), drive bobbins (6) high speed rotating, vibration source is through bearing (3), bearing support (4), reach frame (1) through spring damping (9) and rubber damping (7) again.Spring damping axially is equipped with 2 groups along bearing support, and 6 every group is that 1.8 millimeters spring wire is made by diameter.Rubber damping axially is equipped with two groups along bearing support, and 6 every group, to make by chloroprene rubber, its diameter is 13 millimeters, high 20 millimeters.The utility model embodiment once tested under working condition, and when the drawing wire machine rotating speed was 7200 rev/mins, the drawing wire machine running was steady, and the head amplitude only is 1/4 when using the rubber ring vibration-control system merely, and noise has descended 8 decibels than originally.
Claims (8)
1, a kind of glass fiber wire-drawing machine head vibration-control system is characterized in that being equipped with in the outside of bearing support (4) main damping element spring damping (9) and auxilliary damping element rubber damping (7), and the bearing support and the frame of mandrel revolving meber separated.
2, according to claim 1, it is characterized in that spring damping and rubber damping that distribute vertically can be the 1-6 groups.
3, according to claim 1, it is characterized in that in every group along radially-arranged spring damping of bearing support or rubber damping can be 3-15 only.
4, according to claim 1 or 2 or 3 described, it is characterized in that every group of rubber damping can also be replaced by the rubber damping ring.
5, according to claim 1 or 2 or 3 described, it is characterized in that spring damping can be a compression spring, also can be sheet spring or leaf spring.
6, according to claim 5, it is characterized in that spring damping can use wire such as spring steel, stainless steel, bronze or tinsel to make.
7, according to claim 1-4, it is characterized in that rubber damping can be the column of various cross-sectional shapes.
8, according to claim 7, it is characterized in that rubber damping can be by rubber or engineering plastics making.
