BEARING BEARING WITH SEALING DEVICE. TECHNICAL FIELD [0001] The present utility model refers to a roller bearing with a sealing device.

BACKGROUND TECHNIQUE [0002] A machine, such as a conveyor that is used in mining equipment, is also used in a harsh environment, such as a mountainous region or a desert region. For this reason, for a bearing that is used on such a machine, it is desirable to improve the durability and service life by providing a sealing device. In a related technique, Patent Document 1 discloses as a bearing that is provided with a sealing member, a bearing that has the capacity to prevent infiltration of water or foreign matter through both ends by attaching oil seals to seal enclosures on both end sections of an outer ring.

[0003] In addition, a machine, such as a conveyor that is used in mining equipment, is often used under heavy load and impact load conditions. For this reason, a self-aligning cylinder bearing with a large load capacity is used in such a machine. In a related technique, Patent Document 2 discloses as a self-aligning cylinder bearing that is provided with seals, a bearing that is capable of preventing the infiltration of water or foreign matter through both ends by oil seals that are assembled by means of coreless bars that are fitted at both ends of an outer ring.

SUMMARY OF THE UTILITY MODEL

PROBLEM TO BE SOLVED [0006] Here, in the bearing of Patent Document 1, the bearing pressers are required on both sides of the bearing, in an axial direction, since a sealing shell is not fixed to the outer ring in the axial direction . For this reason, there is a problem where using the bearing is difficult in a free lateral position. In addition, there is a problem where it is difficult to get the bearing to move in the axial direction, since the bearing pressers are used, and the use of the bearing is difficult in a device where an axis expands and contracts, due to thermal expansion, for example, a conveyor, a vibrating screen or the like, which is used in mining equipment.

[0007] In addition, it is necessary to measure the bearing clearance by inserting a thickness gauge or similar in a space between an outer ring sliding surface and a cylinder, in order to confirm a bearing assembly state. However, in the bearing of Patent Document 2, there is a problem in which the bearing gap measurement is difficult, since it is difficult to remove an oil seal after assembly. In addition, likewise, there is a problem where maintenance, such as confirmation of bearing condition and additional grease filling, during use, is difficult.

[0008] The present utility model is realized in consideration of the above circumstances and its objective is to provide a rolling bearing with a sealing device in which it is possible to improve sustainability and which can be used in a free lateral position or a position where the bearing must be movable in the axial direction.

FIRST MODE [0037] The rolling bearing with the sealing device, according to the first modality of the present utility model, is described below using Figure 1. As shown in Figure 1,

Petition 870160001485, of 01/21/2016, p. 39/45

6/16 a self-aligning cylinder bearing 100, according to the first embodiment, has, for example, an outer diameter of 540 mm, an inner diameter of 320 mm and a width of 176 mm, and a plurality of spherical cylinders 13 , 13 is arranged between an inner ring and an outer ring 12 in two rows. Each row of spherical cylinders 13 is held in fixed spaces in a peripheral direction by an integral machined cage (hereinafter, referred to simply as a cage) 16.

[0038] The inner ring 11 is provided with two rows of sliding grooves 11a and 11a on an outer peripheral surface 11c, and the sliding surfaces 11b and 11b are formed at the bottom of the groove in the sliding grooves 11a and 11a. An inner peripheral surface 11f of the inner ring 11 is formed in a tapered shape.

[0039] The outer ring 12 has a sliding surface 12a which is a spherical concave surface on an inner peripheral surface, with a center of curvature of the sliding surface 12a corresponding to a center of the self-aligning cylinder bearing 100 and the property self-alignment of the self-aligning cylinder bearing 100 is guaranteed. An injection orifice 12b for injecting lubricant, such as grease, is formed so that it passes through the outer ring in an intermediate position in a wide direction of the outer ring 12, in at least one place in the peripheral direction.

[0040] The spherical cylinders 13 arranged in each row have a drum-shaped bearing surface 13a and are rotated between the sliding surface 11b of the inner ring 11 and the sliding surface 12a of the outer ring 12.

[0041] Cage 16 is made of metal, being a machined cage that is manufactured by the cutting process and is used in an outer ring guide. The cage 16 is formed by an annular body 16a with an annular shape that extends along a peripheral direction of

Petition 870160001485, of 01/21/2016, p. 40/45

7/16 a central section between the sliding surfaces 11b, 11b, and 12a and a plurality of column sections 16b and 16b that are provided so as to project in the axial direction in the respective spaces fixed on both sides of the annular body 16th. A plurality of pockets are formed by the axially directed side surfaces of the annular body 16a and the adjacent column sections 16b and 16b, along the peripheral direction of the cage 16. Each cage pocket 16 is formed so that it is displaced by a medium - step in the peripheral direction between each row of cylinder. The cage 16 which is configured in this way forms each row of cylinders respectively on both sides of the annular body 16a, individually accommodating each row of spherical cylinders 13 in each pocket, and retains each row of cylinders of spherical cylinders 13, so that can rotate freely in a fixed space along their peripheral direction. In addition, each row of spherical cylinders 13 is arranged so as to alternatively interpose the annular body 16a.

[0042] A sealing device 20 is configured from a sealing bracket 21 which is attached to an axial end surface 12d of the outer ring 12 and a seal 26 covering a coreless bar 25 which is inserted into a groove ring 24 which is formed on an inner peripheral side of the sealing support 21. The coreless bar 25 has a substantially L-shaped cross section and has a substantially cylindrical shape extending radially inward. In addition, a side end section of the outer diameter of the coreless bar 25 extends radially outwardly so as to be retained by the annular groove 24 between the seal support 21 and the axial end surface 12d of the outer ring 12. A seal 26 is formed by an elastic body, such as rubber, and extends radially inwardly along the coreless bar 25. seal 26 is further reinforced by a

Petition 870160001485, of 01/21/2016, p. 13/45

8/16 ring 29 in a lumbar section, which is tilted axially inward, in a proximity of the outer peripheral surface 11c of the inner ring 11, and has a flange section 28 which is tilted axially outwardly, in an end section radially inside. A fixing spring 27 is fitted on an outer peripheral side of the flange section 28. A bearing space is sealed by the flange section 28 which is in sliding contact with the outer peripheral surface 11c of the inner ring 11, it is possible to prevent infiltration of liquid or foreign matter from an external section and it is possible to prevent the flow of lubricant that is filled inside the bearing space.

[0043] Here, the seal holder 21 is formed with a plurality of screw insertion holes 22 that are provided in substantially equal spaces and the outer ring 12 is formed with a plurality of screw holes 12e that are opened to the surface of axial end. The sealing support 21 is fixedly attached to the outer ring 12, by inserting and screwing a plurality of screws 23 into the plurality of screw insertion holes 22 and into the screw holes 12e. For this configuration, it is not necessary to use a bearing press, since the sealing support 21 is firmly fixed in the axial direction to the outer ring 12, and then to the self-aligning cylinder bearing 100. Thus, it is possible to simplify a structure , and it is possible to maintain the sealing performance of the self-aligning cylinder bearing 100, during use in a free lateral position of the device and in a position where the bearing must be movable in the axial direction. In addition, since a main section of the screw 23 is embedded in the seal holder 21 and has a structure so that it does not protrude from the axially external end surface of the seal holder 21, processing for a housing is not required separately, the

Petition 870160001485, of 01/21/2016, p. 14/45

9/16 in order to release the main section of the screw 23, and it is possible to adopt a similar housing structure for the related technique.

[0044] Here, the axial end surface 12d of the outer ring 12 and the end surface of the seal holder 21 which faces the axial end surface 12d are staggered on a radially external side, in a position into which the screw 23 is inserted. The step is used to align a core of the sealing device with a core of the bearing. In particular, in a housing where an outer ring insert 12 is a clearance fit, there is a possibility that the seal holder 21 is not disposed on the same core as the outer ring 12, and as a result, there is a possibility of that sealing performance is reduced without maintaining the sealing tension in a fixed range. For this reason, using the step, it is possible to guarantee the sealing performance by having the sealing support 21 and the outer ring 12 in the same core.

[0045] Furthermore, as described above, the inner peripheral surface 11f of the inner ring 11 is formed in a tapered shape, but when the amount of thrust of the bearing in the axial direction is large, the inner ring 11 expands and a clearance of bearing is reduced. According to the self-aligning cylinder bearing 100 with a sealing device of the present modality, it is possible to measure the bearing clearance for the purpose of confirming the state of assembly of the bearing before use, since it is possible to easily remove the bearing device. seal 20 by removing screw 23. Proper removal is possible and sustainability is enhanced by pressing the bearing in the axial direction such that the measured value of the bearing gap becomes an appropriate value.

[0046] In addition, according to the self-aligning cylinder bearing 100 with the sealing device of the present modality,

Petition 870160001485, of 01/21/2016, p. 15/45

10/16 it is possible to easily carry out maintenance, such as additional lubricant filling or bearing condition confirmation, even during use, since it is possible to easily remove sealing device 20 by removing screw 23. In addition , it is also possible to further improve the sealing performance, since a position of the seal 26 is also fixed by fixing the seal support 21.

[0047] Here, it is preferable to form a surface layer of at least one of the inner ring 11, the outer ring 12 and the spherical cylinder 13 using a material that is subjected to treatment by carburation or carbonitration, with an amount of residual austenite (yR in% in vol.) of 20% in vol. at 45% by vol. Alternatively, it is preferable to form a surface layer of at least one of the inner ring 11, the outer ring 12 and the spherical cylinder 13, formed of a metal alloy that, with an amount of residual austenite (yR in% in vol. ) of 20% by vol. at 45% by volume, contains C: 0.1% to 1.2% by weight, Cr: 1% to 3% by weight and additionally contains 2.0% by weight or less of Mo which is at least 1 / 3 or more of Cr, and the surface hardness (Hv) of the surface layer that is subjected to carburization or carbonitration treatment has a range of -4.7 χ (yR in% in vol.) + 920 <Hv <- 4.7 χ (yR in% in vol.) + 1,020 in relation to the amount of residual austenite. Alternatively, it is preferable to form a surface layer of at least one of the inner ring 11, the outer ring 12 and the spherical cylinder 13, formed of a metal alloy that, with an amount of residual austenite (yR in% in vol. ) of 20% by vol. at 45% by volume, contains C: 0.1% to 1.2% by weight, Cr: 1% to 3% by weight and additionally contains 2.0% by weight or less of Mo which is at least 1 / 3 or more of Cr, and the surface hardness (Hv) of the surface layer that is subjected to carburizing or carbonitration treatment has a rating of 870160001485, from 01/21/2016, p. 16/45

11/16 x -4.7 χ (yR in% in vol.) + 920 <Hv <-4.7 χ (yR in% in vol.) + 1,020 in relation to the amount of residual austenite. It is possible to further improve the durability of the self-aligning cylinder bearing 100 and define a long service life by forming the surface layer of at least one of the inner ring 11, the outer ring 12 and the spherical cylinder 13 with these materials. Here, it is desirable to use these materials for the surface layer of any of the inner ring 11, the outer ring 12 and the spherical cylinder 13, but it is possible to obtain a sufficient effect, even in a case where only a part that is easily damaged is used, for example, these materials can be used only on the surface layer of the inner ring 11 in a case where the self-aligning cylinder bearing 100 has the rotating outer ring. In addition, it is possible that the sealing support 21 uses carbon steel (for example, S25C or S45C).

[0048] In addition, in the present embodiment, an outer member is configured by the outer ring 12 and a pair of sealing brackets 21 that are attached to both axial end sections of the outer ring 12, and an inner member is configured by the inner ring 11, in which case the width in the axial direction of the outer member and the inner member are designed to be the same dimensions. Thus, the outer and inner members are easily constructed in the housing or on an axis, and the handling of the roller bearing is improved.

[0049] Thus, according to the self-aligning cylinder bearing 100, with the sealing device of the present embodiment, it is possible to easily remove the sealing device 20, even after the bearing assembly. This makes it easier to carry out maintenance, such as confirming the bearing status and additional grease filling during use, and it is possible to measure the clearance

Petition 870160001485, of 01/21/2016, p. 17/45

12/16 of bearing before use and during use, in order to confirm the state of assembly of the bearing. In addition, according to the self-aligning cylinder bearing 100 with the sealing device of the present embodiment, use is possible in a free lateral position or a position where the bearing must be movable in the axial direction.

SECOND MODE [0050] The bearing housing with the sealing device, according to the second modality of the present utility model, is described below using Figure 2. The same reference numbers, as in the first modality, are provided at a portion that has the same configuration, and the description is omitted.

[0051] As shown in Figure 2, a self-aligning cylinder bearing 200, according to the second embodiment, is additionally provided with an O-ring 30 between the axial end surface 12d of the outer ring 12 and the axial end surface which is facing the sealing support 21. The O-ring 30 is arranged more radially inward than the screw 23. In this way, it is possible to further improve the sealing performance by arranging the O-ring 30, and it is possible to prevent infiltration of liquid or foreign matter from a radial outer side of the outer ring 12 of the self-aligning cylinder bearing 200 to the inner side of the bearing through the screw insertion hole 22 and the screw hole 12e.

[0052] Here, in the first and second modes described above, there is a possibility that a seal tension 26 will be reduced excessively and the shaft traceability will deteriorate. In addition, there is a possibility that seal 26 is unable to withstand lubricant pressure within the bearing space and that seal performance cannot be guaranteed. However,

Petition 870160001485, of 01/21/2016, p. 41/45

13/16 when the tension of the seal 26 is excessive, abrasion tends to occur between the flange section 28 and the outer peripheral surface 11c of the inner ring 11. For this reason, it is preferable that the tension of the seal 26 is 10 to 100 N, and even more preferably 30 to 80 N.

[0053] In addition, in Figure 2, an annular groove 12f that accommodates the O-ring 30 is formed on the axial end surface 12d of the outer ring 12, which is easy to guarantee a space. However, when the annular groove 12f is formed only on the axial end surface 12d of the outer ring 12, in the case of a heavy load, there is a possibility that the tension generating range that a cylinder receives from the ring sliding surface external, reach the annular groove 12f. For this reason, as shown in Figure 3, the O-ring 30 can be arranged in annular grooves 12f and 21a that are formed both on the end surfaces in the axial direction of the outer ring 12 and on the sealing support 21, in such a way that the tension does not reach the annular groove 12f.

[0054] Furthermore, while the space limitation problem is solved, as shown in Figure 4, from the point of view described above, the O-ring 30 is ideally arranged only in the annular groove 21a, which is formed on the end surface axial of the sealing support 21.

THIRD MODE [0055] The bearing housing with the sealing device, according to the third modality of the present utility model, is described below using Figure 5. The same reference numbers, as in the first modality, are provided at a portion that has the same configuration, and the description is omitted.

[0056] As shown in Figure 5, a self-aligning cylinder bearing 300, according to the third modality, is configPetição 870160001485, from 01/21/2016, pg. 42/45

14/16 from a seal holder 41 that is attached to an axial end surface 11d of the inner ring 11 and a seal 46 that is inserted into an annular groove 44 that is formed on an inner peripheral side of the holder seal 41. The seal 46 is formed of an elastic body, such as rubber, and, in a lateral end section of the outside diameter, there is a flange section 48 that is in sliding contact with an inner peripheral surface 12c of the outer ring 12 A bearing space is sealed by the flange section 48 which is in sliding contact with the inner peripheral surface 12c of the outer ring 12, it is possible to prevent infiltration of liquid or foreign matter from an external section and it is possible to prevent the flow of lubricant that is filled inside the bearing space. According to such a configuration, it is possible to reduce manufacturing costs, since it is possible to use the outer ring 12 which has a feature of the related technique.

[0057] In addition, in the present embodiment, an inner member is configured by the inner ring 11, and a pair of sealing brackets 41 that are attached both to the axial end sections of the inner ring 11 and an outer member is configured by the ring outer 12, in which case the width in the axial direction of the outer member and the inner member are designed to be the same dimensions. Thus, the outer and inner members are easily constructed in the housing or on an axis, and the handling of the roller bearing is improved.

[0058] Here, the present utility model is not limited to the modalities described above, and the appropriate modifications, improvements or the like are possible. In the embodiments described above, the inner peripheral surface 11f of the inner ring 11 is formed in a tapered shape, but the inner peripheral surface 11f can be formed in a cylindrical shape. In addition, in a case where it is necessary 870160001485, of 01/21/2016, p. 20/45

15/16 it is necessary to have screws 23 and 43 additionally firm, the adhesive can be impregnated in screws 23 and 43 and the like.

[0059] In addition, it is possible that the sealing device, in the modalities described above, is attached to both end sections of a bearing, different from the self-aligning cylinder bearing, for example, a cylindrical bearing cylinder or a bearing cylinder tapered, or a combined bearing, which is a combination of two or more of the bearings described above, and these belong to the scope of the present utility model. In addition, the bearing housing with a sealing device, according to the present utility model, need not only be a free side of industrial machinery, for example, mining equipment for machinery, and it is also possible to use a fixed side .

[0060] In addition, an arbitrary seal configuration can be applied, even in a case where alternatively the outer ring or inner ring is provided, and in the mode of the first and second modes, the seal configuration can have a bar without core and an elastic body or can be configured by an elastic member, without the bar without core.

[0061] In addition, an orifice section for a fixing member of the present utility model is not limited to the screw insertion hole of the present mode, and a fixing member of the present utility model is not limited to the present modality. That is, the fixing member can be a member for fixing the sealing support to an axial end section of the inner ring or the outer ring, through the orifice section, for the fixing member.
