Definitions
- the invention relates to a rolling bearing according to the preamble forming features of claim 1, which is particularly advantageous as a guide bearing for the central shaft in automatic transmissions or in manual transmissions of motor vehicles can be used.
- the central shaft is mounted in automatic transmissions but also in conventional or automated manual transmissions of motor vehicles between the end-side main bearings in several additional guide bearings to absorb imbalances and forces from their rotational movement can. Since the radial space for such a guide bearing within the transmission, however, is extremely limited, these bearings are currently mainly sliding bearings are used, which with an inner diameter between 15 mm and 50 mm and a bearing width between 8 mm and 20 mm maximum radial height of 1, 7 mm and are usually designed as a composite sliding bearing with a carrier tape made of steel or bronze and a porous bronze sintered frame.
- Such needle sleeves are known, for example, from the catalog "Rolling Bearings" of the applicant, issued October 2008, on pages 681 to 697 and consist essentially of an insertable into a housing bore thin-walled outer ring having two radially inwardly directed ribs on its axial sides
- the needle ring is thereby formed by a needle cage and a plurality in this circumferentially uniformly spaced bearing needles formed on the formed as a raceway inner surface of the outer ring and on the likewise unroll as outer raceway surface of the shaft to be supported.
- the invention is therefore the object of the invention to design a rolling bearing, which can be used at the bearings of the guide bearings in automatic transmissions or automated manual transmissions of motor vehicles without changes in the surrounding construction.
- this object is achieved by the use of a trained according to the preamble of claim 1 needle sleeve, which corresponds to the outer diameter of the shaft to be stored enveloping circle diameter between 15 mm and 50 mm and at the outer distance of their shelves corresponding bearing width between 8 mm and 20 mm only one of the diameter of the bearing needles and the material thickness of the outer ring formed radial height of maximum 1, 7 mm and whose outer ring, the needle cage and their storage needles are made without cutting of such materials that they against a at operating temperatures of - 40 ° C to at least + 140 ° C and at operating speeds up to 7000 min "1 used plain bearing with the same radial height, the same inner diameter and the same bearing width without changes in the surrounding construction is interchangeable.
- the needle cage is made as a starting material of a steel sheet of the grade DC03 with a thickness of about 0.7 mm and whose surface is subjected to a heat treatment by curing.
- a plastic cage with a similar material thickness would also be conceivable here.
- the needle sleeve according to the invention is characterized by the fact that its needles consist of a steel wire of the grade 100Cr6 with a diameter of at most 1 mm and are subjected to a heat treatment by hardening and tempering.
- a heat treatment of the bearing needles however, carbonitriding would come into question.
- the needle sleeve according to the invention thus has the advantage over the needle sleeves known from the prior art that they have only a radial height of maximum 1.5 mm by forming their individual parts with the lowest possible radial dimensions and optimally suitable materials with targeted heat treatment. and is thus interchangeable with almost any plain bearing having an inside diameter between 15 mm and 50 mm and a bearing width between 8 mm and 20 mm without changes in the surrounding construction.
- FIG. 1 is a plan view of a needle sleeve formed in accordance with the invention and inserted in a housing;
- Figure 2 shows the cross section A - A of Figure 1 by an inventively designed needle sleeve;
- FIG. 3 shows an enlarged view of the detail X of the needle sleeve according to FIG. 2 formed according to the invention.
- a needle sleeve 1 designed according to the invention is shown schematically, which essentially consists of a thin-walled outer ring 4 which can be inserted into a bore 2 of a housing 3 and has two radially inwardly directed ribs 5, 6 on its axial sides, and one of these Borden 5, 6 held in the outer ring 4 needle ring 7 consists.
- this needle ring 7 is formed by a Nadel tannin- fig 8 and a plurality in this circumferentially uniformly spaced bearing pins 9, which roll on the inner circumferential surface 10 of the outer ring 4 and on the outer circumferential surface of a shaft, not shown to be stored.
- Figures 2 and 3 can be seen in addition that the needle sleeve 1 at a the outer diameter of the shaft to be stored enveloping circle diameter d H between 15 mm and 50 mm and at the outer distance of their shelves 5, 6 corresponding bearing width b between 8 mm and 20 mm in accordance with the invention, only one of the diameter of the bearing needles 9 and the material thickness of the outer ring 4 formed radial height h of maximum 1, 7 mm, wherein the non-cutting produced outer ring 4 of a heat-treated by case hardening and tempering steel sheet DC04 modified with a maximum thickness of 0.7 mm.
- the needle-cage 8 also made without cutting, consists of DC03 steel sheet having a thickness of about 0.5 mm and a hardened surface, and the bearing needles 9 are hardened and tempered 100Cr6 steel wire having a diameter of 1 mm or less are formed, the needle sleeve 1 is thus against a Operating temperatures from - 40 ° C to at least + 140 ° C and at operating speeds up to 7000 min "1 used plain bearing with the same radial height, the same inner diameter and the same bearing width without changes in the surrounding construction interchangeable.
- a needle sleeve 1 formed in this way can be used in exchange for the previously designed as plain bearings guide bearing for the central shaft in an automatic transmission or in a manual transmission of a motor vehicle, where it has proved to be useful, the needle sleeve 1 on its outer ring 4 in addition two punched out, obliquely outwardly formed and in operative connection with an annular groove 14 in the housing 3 lugs 15 of the type shown in Figures 2 and 3 form, by which it is secured against axial slipping.

Abstract
L'invention concerne une douille à aiguilles (1) avec un anneau externe (4) à fines parois pouvant être intégré, qui présente sur ses côtés axiaux deux bordures (5, 6) orientées radialement vers l'intérieur et composé d'une couronne d'aiguilles (7) maintenue dans l'anneau externe par ces bordures. La couronne d'aiguilles est formée par une cage à aiguilles (8) et une pluralité d'aiguilles de roulement (9) placées à l'intérieur à espacements réguliers dans le sens de la circonférence. Selon l'invention, avec un diamètre de cercle inscrit correspondant au diamètre externe de l'arbre à soutenir compris entre 15 mm et 50 mm et avec une largeur de palier correspondant à l'écart externe de ses bordures compris entre 8 mm et 20 mm, la douille à aiguille présente d'une part uniquement une hauteur de construction radiale de 1,5 mm maximum et d'autre part, son anneau externe, sa cage à aiguilles, ses aiguilles de palier sont fabriqués sans enlèvement à partir d'un matériau tel que celle-ci peut être échangée avec un palier lisse utilisé à des températures de service de - 40 °C à au moins + 140 °C, ainsi qu'à des régimes de fonctionnement pouvant atteindre 7000 min-1, avec une hauteur de construction radiale identique, un diamètre interne identique et une largeur de palier identique, sans modifier la construction qui l'entoure.
