Description

Field of the invention

The invention relates to an outer ring for a cylindrical roller bearing, consisting of a raceway tube, which is made of a bearing steel, and the raceway tube radially outer enveloping tube, which consists of a low-cost, less high-quality, low alloyed or unalloyed steel and lateral, radially having internally extending shelves, wherein the ribs radially overlap the raceway tube and axially position this in the cladding tube.

Background of the invention

A similar outer ring is from the DE 10 2013 213 928 A1 known. The raceway tube is spirally wound and surrounded by a cladding tube radially outside, which has at its axial ends in each case a board. The two ends of the cladding tube bent into a ring are connected to each other by a closure, wherein one end has a mushroom-shaped end portion which is inserted into a counter-shaped, an undercut forming recess at the other end. This outer ring has proven itself in principle, but problems with the Borden occur when bending the cladding tube when they are to protrude radially inwardly over the raceway tube to guide the cylindrical rollers of the cylindrical roller bearing. You can, for example, wavy in the circumferential direction, because they are compressed during round bending. Furthermore, the production of the closure and its connection to the finished bent cladding is expensive.

Object of the invention

Against this background, the invention has the object to simplify the production of the cladding tube and to make cheaper, to increase the manufacturing accuracy and to achieve a safe and smooth surface contact of the raceway tube on the inner surface of the cladding tube.

Description of the invention

This object is achieved with an outer ring for a cylindrical roller bearing, consisting of a raceway tube, which is made of a bearing steel, and the raceway tube radially outer enveloping tube, which consists of a low-cost, less high-quality, low-alloyed or unalloyed steel and lateral, itself having radially inwardly extending shelves, wherein the ribs radially overlap the raceway tube and axially position this in the cladding tube. In this outer ring is provided according to the invention that the cladding tube consists of at least one thick-walled piece of pipe, which is formed undivided transversely to its circumference, and that at least one circularly wound to a raceway tube sheet metal strip is inserted in this cladding tube.

The raceway tube thus consists of a strip material made of high-quality, hardenable bearing steel, which is cut to length, bent around and welded. The raceway tube consists for example of the bearing steel C80M or 100Cr6. The cladding serves only as a spacer to a surrounding structure and is made of a low-cost, less high-quality, low-alloyed or unalloyed steel.

According to a first development of this outer ring is provided that the raceway tube consists of several parallel, each individually bent from a sheet metal part of the raceway tubes, wherein the wound to a raceway tube or several Teillaufbahnrohren sheet metal strip is welded in the region of its circumferentially abutting butt ends to each other. Here, it is preferably provided that the abutting ends of the Teillaufbahnrohre extend at an angle of less than 90 ° to the circumferential direction, so that the cylindrical rollers load when rolling over these connecting portions always only a portion of the weld. The one raceway tube or the several partial raceway tubes can be connected by gluing or soldering after the mentioned joining with the radially outside arranged cladding tube.

According to a second embodiment it is provided that the cladding tube consists of two radially divided, undivided transversely to the circumference thick-walled partial cladding tubes, each having a lateral, radially inwardly projecting board. If the cladding tube, seen in the axial direction, is performed split radially in the middle, the two cladding tubes can have the same dimensions, and they can thus be mirror-inverted against each other.

In both embodiments, the radial dimension of the ribs is preferably greater than the radial thickness of the raceway tube, so that the ribs not only serve for the axial positioning of the raceway tube, but also can take over the axial guidance of the cylindrical rollers.

Further, it is preferably provided that the rims of the two partial cladding tubes have on their axial inner side an axial circumferential groove for receiving in each case one of the two edge regions of the raceway tube, the radial outer circumferential surface of these circumferential grooves being in alignment as well as in FIG axial extension is formed to the radial inner surface of each partial cladding tube.

Detailed description of the drawings

The in 1 illustrated radial section through a cylindrical roller bearing 1 shows an outer ring 2 * made of a cladding tube made in one piece and undivided from a thick-walled pipe section 2 and a track tube 6 is constructed. The cladding tube 2 serves only as a spacer to a surrounding construction and is made of a low-cost, less high-quality, low-alloyed or unalloyed steel. The raceway tube 6 On the other hand, it consists of a high-quality bearing steel, such as steel C80M or 100Cr6. The radial thickness of the cladding tube 2 is more than four times as large as the radial thickness of the raceway tube 6 ,

The cladding tube 6 has a radial inner surface 3 and two axially end shelves 4 . 5 on. Between the two shelves 4 . 5 is the raceway tube 6 arranged, which as shown the whole width between the two Borden 4 . 5 can take. The raceway tube 6 consists in the first embodiment shown of three juxtaposed partial trough tubes 6a . 6b . 6c , which are close together. On the at the three partial runway pipes 6a . 6b . 6c radially inwardly formed track roll cylindrical rollers 7 from which axially between the two Borden 4 . 5 are guided and by a Ka 8th be kept in a known manner at a distance from each other.

2 shows in an axially cut and partially radially exploded perspective view of the one-piece cladding 2 , of which two shelves in this view only the second board 5 is visible. In the cladding tube 2 are the three partial runway pipes 6a . 6b . 6c arranged. These partial runway pipes 6a . 6b . 6c were bent starting from sheet metal strips to rings and then each circumferentially end welded butt to joint.

In 2 are purely exemplary three different butt-end abutting ends 9 . 10 . 11 the partial runway tubes 6a . 6b . 6c shown. This in 2 shown on the right third part runway tube 6c has abutting ends 9 which are axially parallel and rotated by 90 ° to the circumferential direction. The ends 10 of in 2 very first left partial runway tube shown 6a are complementary to less than 90 ° to the circumferential direction, here inclined at 45 ° to the circumferential direction, while the abutting ends 11 the second, middle part of the runway tube 6b V-shaped, each leg is inclined by about 45 ° relative to the circumferential direction.

The three partial runway pipes 6a . 6b . 6c be in the cladding tube 2 between its two shelves 4 . 5 inserted so that the ends 9 . 10 . 11 the respective partial runway tubes 6a . 6b . 6c Butt to butt against each other, after which they are butt-joined, in particular by welding, together. Subsequently, the inner surfaces of the Teillaufbahnrohre 6a . 6b . 6c at least in the area of the welded, abutting ends 9 . 10 . 11 be reground to a clean, accurate raceway surface for the cylindrical rollers 7 to obtain. The abutting ends 10 . 11 the first two partial trough tubes 6a and 6b are particularly advantageous because the local welds during rolling through the cylindrical rollers 7 are always only partially loaded, so that their intended maximum service life is not affected by the rollover.

The first partial tube 13a has a first radial inner surface 14 and a first board 15 in, in which an axially inwardly open, first circumferential groove 16 is trained. A radial outer peripheral surface 17 this first circumferential groove 16 runs flush in extension to the radial inner surface 14 of the first partial cladding tube 13a ,

Analogously, the second partial cladding tube points 13b a second radial inner surface 19 , a second board 20 and a second, axially axially open axial circumferential groove 21 on, the radial outer peripheral surface 22 flush with the radial inner surface 19 of the second partial cladding tube 13b runs.

The existing raceway tube here 23 consists in this second embodiment of three partial raceway tubes 23a . 23b . 23c , wherein axially outer edge regions 24a . 24b of the raceway tube 23 in the axial circumferential groove 16 of the first partial cladding tube 13a or in the axial circumferential groove 21 of the second partial cladding tube 13b taken up and thereby fixed radially and axially.

One between the two partial ducts 13a . 13b trained V-groove 25 serves a cohesive connection, in particular by means of a weld, the two partial cladding tubes 13a . 13b after assembly with the partial guide tubes 23a . 23b . 23c and inserting the cylindrical rollers 7 in the kitchen 8th make.

Out 4 it can be seen that the three partial raceway tubes 23a . 23b . 23c geometrically identical abutting ends 9 . 10 . 11 have like the three partial runway pipes 6a . 6b . 6c according to 2 , These ends 9 . 10 . 11 can be in this second embodiment, prior to their joining with the two partial ducts 13a . 13b cohesively, in particular by a weld, connect together. The welds in this end areas 9 . 10 . 11 can be in contrast to the embodiment according to the 1 and 2 before joining with the two partial ducts 13a . 13b smooth by grinding, allowing the assembly of the outer ring 2 ** according to the 3 and 4 manufacturing technology is easier, especially since the two partial cladding 13a . 13b can be made identical and are assembled rotated by 180 ° against each other.

The two embodiments presented have the advantage that the main functions of the bearing outer ring 2 * . 2 ** are separated. The raceway tubes are made of high quality bearing steel, in particular of the bearing steel C45M or C80M. They have the raceway of the outer ring and can be made very thin. Occurring voltages during operation are reduced within this career. The ducts of the presented outer rings 2 * . 2 ** consist of less high-quality, but inexpensive and easier-to-machine steel. They assume the function of a spacer, for example to a receiving bore in a bearing housing, and can be performed in different thicknesses, so that an easy adaptation to different bearing diameter with the same inner diameter of the cylindrical roller bearing is possible. Thus, by bending the raceway tube from a strip and welding all widths and diameters of the raceway tube can be finished with a machine and with a bearing steel.

The cylindrical rollers may be formed as small diameter cylindrical needles in proportion to their length or as large diameter cylindrical rollers in proportion to their length.

All the features mentioned in the preceding description of the figures, in the claims and in the introduction to the description can be used both individually and in any combination with one another. The invention is thus not limited to the described and claimed feature combinations, but all feature combinations are to be regarded as disclosed.
