    (54) BEHAVIOR UNDER HALF-LIFE
    The invention relates to the field of engineering, in particular to spherical plain bearings.
    Known petal bearing 5 slide containing movable and. stationary elements and elastic petals mounted on one of them overlapping one another with installation elements placed in grooves, for example, in the form of dowels, as well as petal supporting elements fixed on the latter, located on the side of the supporting surfaces of the overlapped sections of elastic petals ij. In this case, the mounting elements are mounted near the entrance edges of the elastic petals and are installed with a tension in the groove of, for example, the fixed element, and the petal 20 supporting elements are made with a greater curvature than the elastic petals.
    A disadvantage of the known bearing is the rigid attachment of elastic 25 lobes in the grooves of the movable or stationary elements, which can lead in the initial, starting E mode to the output of the mounting element from the groove and the malfunction of the bearing. thirty
    The aim of the invention is to increase the durability and reliability of the bearing.
    This goal is achieved by the fact that in a sliding bearing containing movable and stationary elements and overlapping on one of them, overlapping one another elastic petals with elements placed in grooves and also fixed on the latter are petal supporting elements located on the side of the supporting surfaces of the overlapping portions elastic petals, mounting elements are mounted between the input and output edges of the elastic petals with the possibility of movement relative to the groove.
    The installation elements can be attached to the middle part of the elastic petals and made in the form of rigidly fixed on the supporting surface of the elastic petals of the plates with a thickness smaller than the width of the groove.
    The installation elements can also be made in the form of a U-shaped groove, which is integral with an elastic lobe. Elastic petals can be bent. Trapezoidal form is not provided with a base perpendicular to the mounting element ... In addition, the bearing can be equipped with friction elements installed in the grooves with the possibility of contact with the installation elements. Elastic petals are installed with overlapping one another by the location of the installation elements of adjacent elastic petals and with the formation of the support and carrier sections of the elastic ice-pieces located on both sides of the installation elements. , Subframe Can be fitted with an anti-friction coating located on one of the contacting and bearing surfaces of adjacent petals that are in contact with one another. Flap support elements can be made of the same curvature with elastic petals. , -. Petal supporting elements can be made in the form of elastic elements, working them in bending, and elements working in compression. ; The supporting sections of the elastic petals can be made with alternating Eyubralsh and grooves on both side surfaces, with the edges on one surface located opposite the grooves of the other surface .; FIG. 1 shows a sliding bearing, a slit; in fig. 2 — elastic petal, axonometric in FIG. 3 a bearing with an elastic petal and having anti-friction) digging; in fig. 4 - the bearing with friktsyon shy Elements in a groove; in fig. 5 - Uyug petal with ribs and yazes on both side surfaces; in fig. b an embodiment of an elastic petal with ribs; in fig. 7 - bearing with basic petal elements; in FIG. 8, node I in FIG. 7; figure 9- "shows the elastic petal with a U-shaped installation element; in fig. 10-: - version of the elastic petal; see .. 11 - trapezoidal elastic petal; in fig. 12 conic; cue petal bearing in dismembered form. The sliding bearing contains a sliding 1 and a sliding bearing 2 elements (a shaft and a sleeve, respectively), as well as elastic lobes 3 mounted on the latter, for example, overlapping one another, on which the mounting elements 6c in the form of plates are fixed between the input and output edges 4 and 5 placed in the grooves 7 and ymek tsikh thickness smaller than the width of the groove 7, which provides the ability to move the mounting elements b relative to the grooves. 7. The installation elements 6 can be attached to the middle part of the elastic petals 3 and can be made in the form of a U-shaped trench 8, integral with the elastic petal 3. The elastic petals 3 can be made trapezoidal in shape with the base perpendicular to the installation element b. In the groove 7 can be installed friction elements 9 in contact with the plates b. In this case, elastic petals 3 are installed with one overlapping one another to the location zone of plates b of adjacent elastic petals 3 and with the formation of a supporting 10 and a carrier I of elastic petals 3 located on both sides of the mounting elements 6. On one of the contacting surfaces of the supporting one 10 and carrying 11 sections of adjacent petals 3, an anti-friction coating 12 can be located. Petal supporting elements 13 having the same curvature can be attached to the plates b from the c1 supporting parts 10. elastic lobes 3. The supporting elements 13 are made in the form of elastic elements working on bending, and elements working in compression, for example, respectively, in the form of alternating ribs 14, 15 and grooves 16, 17 on both their side surfaces, while the edges 14 on one surface is located opposite the pair; call 17 on the other surface :: ti. In addition, the ribs 14, 15 and the grooves 16, 17 can be made directly on the support sections 10 of the elastic petals 3. To ensure the lubricating properties and resistance to wear, where it is required, and to control the damping characteristics of the petal bearing elements, Various coatings have been used on the partial surfaces of the petal bearings. The upper surface of the covering carrier section 11 of the petal 3, which is in contact with the shaft 1 before the ascent, may be coated with a high-temperature, high lubricating, resistance to wear coating 12, for example, a laminated fluoroplastic with carbon filler. The upper surface of the coated support section 10 of the petal 3, on which the bottom surface slides The coating carrier section 11 may be coated with coating 18 having lower lubricating properties than coating 12, since there is no contact with shaft 1. A mixture of high-temperature superpolymers, such as polyphenylene sulfide, with wear resistant filler, such as cobalt oxide, can be used. It has been established that the base coated with fluoroplastic laminate should have a special treatment to increase the adhesion with such a coating. Since the lower surface of the coated support section 10 of the petal 3 slit on the inner surface of the sleeve 2, this inner surface can be coated with a coating 19 of a material similar to coating 18. Coating 12, 18 and 19, 20 can be applied only to the flat surfaces of the ribs 14 , 15, or cover the entire wood pestle 3 or the supporting element 13. Relative slip between the lower surface of the covering carrier section 11 of the petal 3 and the coating 18- on the upper surface of the coated support section 10 of the petal 3 and between the bottom corner The characteristic of the coated support section 10 of the petal 3 and the coating 19 on the inner surface of the sleeve 2, together with the compression of the strap formed by the adjacent mutually overlapping petals 3, significantly affects the damping effect of the petal bearing. By correct selection of materials for coatings 18 and 19, this damping effect can be controlled. The damping of the subplate can also be carried out by friction contact between the mounting plate 6 and groove 7 in the sleeve 2. Adding a coating 19 of friction material to the side surface of the groove 7 in contact with the mounting plate 6 to obtain a non-destructive friction contact reduces the damping of the leaf bearing. In addition to use coatings for friction surfaces of the petal bearing, the petals 3 can be modified in shape to create partial advantages. For example, a petal bearing element 21, including a bearing support element 13 attached to a mounting plate b, may have a bottom surface of the coated support section 10 etched, or slotted to form alternating ribs 15 with flat tops and grooves 17. The top surface also has alternating ribs 14 and the slots 16, with the fins 14 on the upper surface being located between the fins 15 on the lower surface. The grooves 16, 17 ensure proper cooling of the bearings by passing a fluid flow along the length of the element 21. The ribs 14 and 15 have flat tops, so that the petal elements 21 slide one another and the wave formation in the surface of the liquid film is reduced. The total thickness of the molded support section 10 of the petal 21 is measured from the base of the rib 22 to the top of the rib 14 and is preferably equal. the thickness of the covering carrier section 11 of the petal 21. In another design, the thickness of the covering carrier section of the 11 e petal 23 is equal to the thickness of the supporting section 10 of the petal 23 undermined, if measured from the groove 17 to the groove 16. to be accurately and cheaply manufactured by photochemical etching or technological methods, or by attaching a multitude of narrow strips to the surfaces of the lobe. A flap bearing can have a design that can be applied to withstand axial loads, for example, in the form of a flat thrust bearing or a conical petal subsucker. A thrust bearing contains flat trapezoidal elastic petals 24 with fixed: plates 6 on them. At the same time, elastic petals 24 do not necessarily have to overlap one another. A conical bearing contains conical elastic petals 25 with mounting plates 6 fixed in the middle part of conical petals 25, which may have a different design embodiment described. When the shaft 1 is rotated inside the sleeve 2, the pliable bearing lobes 3 are squeezed in the space between the shaft 1 and the sleeve 2 so that the coated support section 10 of the petal 3 creates an elastic support. 2. Each petal 3 acts as a flexible arm, pivotally fixed and resting on one end of petal 3 on the inner surface of sleeve 2, and on the free end of petal 3 on the supporting portion 10 of the adjacent bearing Ivy lobe 3. Under load. Individual bearing lobes 3 tend to bend between support points. The end of the coated support section 10 of the petal 3 tends to slide along the inner surface of the sleeve 2, while the free end of the cover; the supporting section 11 of the petal 3 slides over the next adjacent bearing petal 3. The movement of the bearing petals 3, however, is limited by the mounting plate 6 into the groove 7, including due to the friction of the plate 6 and the friction coating 9. In this case, the oscillations of the shaft 1 are reliably damped. The bearing, equipped with a support element 13, has a higher bearing capacity lower initial torque and better centering than a bearing without
    support element 13, but with a higher tolerance of the outer side of the circle: they have a lightweight 3,
    The grooves 16 and 17 provide better cooling of the petals 3 ..
    The invention allows to increase the durability of bearings and the reliability of their work.
