The annular supporting portions are represented either by separate supporting rings (4") installed in body element (3') with the supporting surfaces of different diameters, or by one supporting ring (4"), which can bend in the radial direction and is supported in such a way that the second annular supporting part can bend under effect of a load in the radial direction, while its supporting surface will occupy a position with a diameter bigger than the diameter of the supporting surface of the first annular supporting part (4"). Supporting ring (4") is installed in body (3') in seat (5") with shaped base (7") or conical base (9"). EFFECT: removal of a pinpoint contact between a tubular element and a supporting ring reducing wear and pressure. 13 cl, 5 dwg
The technical field to which the invention relates. The present invention relates to a bearing Assembly, which serves as a support for the tubular element is subjected to lateral deflecting forces, which can increase the wear between the said tubular element and the support ring. This problem may occur for the lower bearing of the moving pipe strut of the landing gear of the aircraft. The level of technology In the General case, the bearing Assembly for moving pipe strut of an aircraft contains the lower bearing and the upper bearing, lower bearing typically includes a housing that supports one or two smooth support ring located at a distance from each other in the axial direction and having the same diameters. The pipe can slide in bearings in the axial direction, however, if it is bent in the lateral direction, it can load an edge support ring that is closest to the edge in the direction of the axis, as shown in figure 1, creating a point-contact, high pressure and rapid wear. As a solution to this problem was proposed to give to the conical shape of the inner surface of the support ring in the area closest to the edge in the direction of the axis, there may be a point of contact for t the th, to increase the surface area of possible contact. The taper may be small and be only half degrees. However, if the optimization of logistics and repairs are a snap slewing rings, you must follow the correct installation of this tapered bearing, because if not installed and there is the risk of loss of the supporting surface and the lack of reduction of pressure on the edge. To prevent incorrect Assembly, you can use the lock, but increases the cost. Disclosure of inventions The invention relates to a bearing Assembly, comprising a housing supporting the first and second annular bearings with bearing surfaces that are in contact with the inner tubular element at sites remote from each other in the axial direction, characterized in that the said annular supporting part presents or separate support rings mounted in the hull element, with the support surfaces of different diameters, or one support ring, which may be bent in the radial direction and is supported so that the second annular supporting part of the load may be bent in the radial direction, with its bearing surface occupies a position with a large dia is the ETP, than the diameter of the position of the supporting surface of the first annular support part. In the embodiment of the invention using two separate support rings, the second ring with a large diameter bearing surface comes into contact with the tubular element only in the case when the latter is bent under the action of the load, whereby the tubular element is in contact with the outer axial edges of both support rings in the direction of that end of the bearing, by which the load of the tubular element. In the embodiment of the invention, in which one bearing ring forms these two annular support part, the support ring can be placed in the nest with the cone in the axial direction or shaped, perceiving the bending of the specified second annular supporting portion, which is located at that end of the bearing, by which the load of the tubular element. In both the above options implemented, it is possible to use essentially the standard snap-in bearings with split rings that do not have conical bearing surfaces and do not require any special Assembly. In the case of two separate support rings snap rings can be identical, and the base surface of the larger diameter of the second bearing is only the result of expansion of the bearing in accordance with a large diameter socket in the housing. In an alternative embodiment of the invention three or more support rings can be installed in the housing, with a gradual increase of the diameters of their supporting surfaces. In another alternative embodiment of the invention, two support rings can be formed from one support ring, with the two ring bearings, one of which under the action of loads may be bent into a position of greater diameter than the other. The second support ring can be located on either side of the first support ring, closer or farther relative to that end of the bearing, by which the load is applied to the tubular element. In the previous configuration of the second support ring preferably has a bearing surface with a larger diameter, which can thibetica specified first annular portion of the bearing, while in the latter configuration, the second support ring preferably has a bearing surface of the same or smaller diameter as specified second annular support portion. In the latter configuration, it is possible the combination of these two embodiments of the invention. In other alternative embodiments the invention, the tubular element may have lateral bending by any axial end of the bearing, is that the bearing may be symmetrical relative to the Central diametrical plane and has one or more support rings with larger diameter bearing surfaces, provided on each side of one or more internal support rings having a smaller diameter bearing surface; or the outer side in the axial direction of the support ring provided on each side of the inner part so as to provide the possibility of bending under the action of the load in the radial direction to a position of larger diameter. Brief description of drawings Below is a description of an example embodiment of the invention with reference to the accompanying drawings, on which: Figure 1 - schematic view in section of a known bearing Assembly that supports a sliding tube landing gear of the aircraft. Figure 2 - schematic view in section of a bearing Assembly according to the first variant embodiment of the invention; Figure 3 - schematic view in section of a bearing Assembly according to the second variant embodiment of the invention; 4 is a view similar to figure 3 but showing the bending of the sliding tube; and 5 is a schematic view in section of a bearing Assembly according to a third variant embodiment of the invention with three support rings. The implementation of the invention Moving the pipe 1 strut main landing gear of the aircraft shown in figure 2 in its vertical position, supports the lower end of the wheel or cart Sass is. The tube 1 is supported in upper and lower bearings 2 and 12 in the cylindrical housing 11 hours. The upper bearing 12 can be attached to a sliding tube, so that it slid into the housing bore 11. Alternative upper bearing 12 may be attached to the housing bore 11, so that the sliding tube slid in it. The lower bearing 2 is attached to the lower end of the housing 11, the moving pipe can slide in the axial direction in the lower bearing. During operation, the forces acting on the wheel or truck chassis taxiing, takeoff or landing, cause lateral bending of the pipe 1, which can create problems of wear in the lower bearing. The lower bearing Assembly includes a housing 3 of the bearing, which has two identical smooth support ring 4 located at a distance from each other in the axial direction, while each ring is located in a respective socket 5 on the inner surface of the housing 3, and all nests have the same depth. Support ring 4 can be a split ring that is snapped into the sockets 5. If the tube 1 has a lateral bending, as exaggeratedly shown in figure 1, it acts with the force of reaction on the upper bearing 12 on one side of the tube and is in contact with the lower edge 6 of the lower support ring 3 on diametral is but the opposite side of the pipe. Contact with the lower support ring first represents at least point contact, which causes rapid wear. The first variant embodiment of the invention shown in figure 2, contains the lower bearing 2' with the tubular body 3', supporting two smooth support ring 4', located at a distance from each other in the axial direction, each support ring is in the correct slot 5' on the inner surface of the housing 3' in order to ensure contact with the moving pipe 1' rack of the chassis. Support ring 4' are identical split snap ring support, however, the socket 5' to the lower of the two support rings has a larger diameter than the slot 5' to the top of the two support rings, so the lower support ring extends in the radial direction, in order to occupy a larger diameter at the bottom of the slot 5'. The upper of the two lower support rings 4' when the installation has an internal diameter, which provides support for moving the pipe 1' in the absence of bending, the moving pipe 1' does not touch the bottom of the support ring 4'. However, when the applied load creates lateral bending of the moving pipe 1', as exaggeratedly shown in figure 2, it comes in contact with the bottom in the axial direction of the edges 6' of the support rings 4'. Thus, in comparison with and the known bearing, shown in figure 2, the contact area between the sliding tube 1' and the edges of the support rings 4' in the embodiment shown in figure 2, increases and, consequently, the wear caused by bending of the pipe is reduced, and the friction force is more evenly distributed between the two support rings 4', and decreases the risk of problems associated with heating, in particular with the appearance of microcracks. In order to avoid contact with the bending of the moving pipe G with the bottom edge of the housing 3', the lower edge of the housing 3' may be cut off or beveled, as indicated by reference number 8'. The second variant embodiment of the invention shown in figure 2, a similar variant implementation, shown in figure 2, two support rings 4" lower bearing installed in slot 5" of different depths on the inner surface of the tubular body 3". However, the feature of the second variant implementation is that the socket 5 for the lower of the two support rings has shaped section 7, where the diameter increases towards the lower end of the housing 11. The lower support ring 4 can be bent in the radial direction under the action of load, so the lower part of the lower support ring 4" bent, occupying enlarged in the radial direction part 9" slot 5" and increasing, so is atom, the area of contact with the sliding tube 1, as shown in figure 2. In an alternative embodiment of the invention, the lower of the two lower support rings 4" in figure 2 can be installed in slot 5" so that is closest to the center part of the support ring relied on the same diameter as the upper of the two lower support rings 4". This is closest to the center of the lower support ring is in contact with and supports a sliding tube G in the same manner as the upper support ring 4". In an alternative embodiment of the invention the upper support ring 4 can be excluded, with a sliding tube will only support lower support ring 4". Alternative embodiments of the invention, in particular, as shown in figure 2, may include three or even more support rings located at a distance from each other along the axis of the housing, while the second and each of the following support rings are installed in the slots, the diameter of which gradually increases, thus, the support ring to form a stepped structure in which the sliding tube in lateral bending comes in contact with edges of the rings/step, distributing the load between the edges of the three or more support rings. In the shown embodiments, the implementation of the upper bearing 12 has fo the mu simple fixed bearing, however, it should be understood that it can also be modified according to the invention and may be full or partial repeat the configuration of the lower bearing 2. In other alternative embodiments the invention, the sliding tube 1 may have a lateral bending is not at one end, where it speaks of the strut, and may be a tubular element, which acts on both sides of the bearing, and may have lateral load on both ends.
