The invention relates to the textile industry and relates to a noise-absorbing fence spindles of textile machines.

You know the fence spindles of textile machines, containing mounted on the spun beam machine at the level of its spindles along some fence attached to its inner surface vibroscope layers (SU 1388484 A1, 15.04.1988).

A disadvantage of the known device is relatively low efficiency of noise reduction.

The closest analogue of the claimed invention is a casing of the spindles of a textile machine, which contains the set on spun beam machine at the level of its spindles along some fence with vertically located removable cover and attached to its inner surface vibropower layer and an absorbent layer (KORYCISKI YA and other Vibration and noise in the textile and light industry, Moscow, Light industry, 1974, p.150-151, RIS, s.162).

In this casing is not resolved the aforementioned drawback.

The objective of the invention is to provide a casing for the spindles of a textile machine, providing the technical result consists in increasing the efficiency reduction is created on the machine rotating spindles noise.

This technical result in the casing of the spindles of a textile machine, containing the meters installed on spun beam machine at the level of its spindles along some fence with vertically located removable cover and attached to its inner surface vibropower layer and absorbent layer, is achieved by the fact that the fencing is made from the upper and lower parts, each of which consists of a body made of sheet corners with the angle at the vertex of the 90°rigidly attached to spun the beam at its upper and lower parts, the thickness is placed on the plate vibration-absorbing layer 2÷4 times the thickness of the plates of the housing and the cover, and the casing elements installed on the machine by means of the vibration-insulating rubber gaskets, total hardness which is lower than the rigidity of the vibration-damping suspension of the spindle.

As a material of the vibration-absorbing layer used elastic vibration-absorbing sheet material with a coefficient of internal loss is not less than 0.2, or composite material, or plastic.

As the sound-absorbing material fences are used items from the basalt mineral wool or mineral wool or basalt wool, or glass wool lined with glass wool material, or a foamed polymer, such as polyethylene or polypropylene, and an absorbent element across its surface lined with acoustically transparent material such as glass or polymer.

The sound-absorbing material of the fence is made of soft foamed porous sound-absorbing material, for example foamed foam is of olyurethane or polyethylene, or from a rigid porous sound-absorbing material, for example, penelopina.

The sound-absorbing material of the fence can be made in the form of crumbs from solid vibrocentric materials, such as elastomer, polyurethane, or plastic, placed in a shell of smokeproducing material and particle size of the crumb lies in the optimum range of values: 0,3÷2.5 mm

The drawing shows the casing of the spindles of a textile machine.

The casing of the spindles of a textile machine includes installed on spun beam machine 1 at the level of its spindles 2, rotating the belt 3, along with their number of fence attached to its inner surface vibroscope layers 4. Fencing is made from the upper and lower parts, each of which consists of a body made of sheet corners with the angle at the vertex of the 90°rigidly fixed to spun the beam at its upper and lower parts, and located vertically removable cover 5. All elements of the cover installed on the machine by means of the vibration-insulating rubber gaskets 6, total hardness which is lower than the rigidity of the vibration-damping suspension of the spindle 2. The thickness is placed on the plate vibration-absorbing layer (not shown) in 2÷4 times the thickness of the plates of the housing and cover. As a material of the vibration-absorbing layer used elastic vibration-absorbing sheet Mat is a material with a coefficient of internal loss is not less than 0.2, or composite material, or plastic-type "agate", "Antifibrin", "Swim". As the sound-absorbing material of the fence are the elements of basalt mineral wool on the basis of type "Rockwoot", or mineral wool of type "URSA", or basalt wool type P-75, or glass wool lined with glass wool material, or a foamed polymer, such as polyethylene or polypropylene, and an absorbent element across its surface lined with acoustically transparent material, such as fiberglass type EZ-100 or a-type polymer Povide".

The sound-absorbing material fence made in the form of crumbs from solid vibrocentric materials, such as elastomer, polyurethane, or plastic-type "agate", "Antifibrin", "Swim", placed in the shell of smokeproducing material and particle size of the crumb lies in the optimum range of values: 0,3÷2.5 mm (not shown).

You can perform a sound-absorbing material of the fence based on the aluminium-containing alloys, followed by filling them with titanium hydride or by air with a density in the range of 0.5÷0.9 kg/m3with the following mechanical properties: compressive strength within a 5÷10 MPa, a bending strength in the range of 10÷20 MPa, or from soft foamed porous sound-absorbing material, for example foamed p is copolyurethane or polyethylene, or from a rigid porous sound-absorbing material, for example, penelopina.

The cover works as follows.

During operation of the machine created its spindles energy of the sound pressure is absorbed by the sound absorbing layer 6 of the fencing, and the vibration-absorbing layer DAMPS vibration of thin metal casing, which is the source of acoustic vibroplasty. The effect of damping increases with the removal of the vibration-absorbing layer from the neutral axis of spun beam bending due to the increase in deformation. This effect just is implemented in this design fence slats, which provide the spatial damping loss factor which is 0.2 compared to 0.05 in the normal damping in the frequency range from 200 to 3000 Hz. Remove vibration-absorbing viscoelastic layer from the neutral axis of spun beam bending causes increase in deformation of the casing and straps, which leads to increased friction between the vibration-absorbing layer and the cover and straps and helps to dissipate energy vibroplasty.
