【発明が解決しようとする課題】
しかし、内軸受の孔および内軸受に取り付けられるジャーナルは、それぞれ、軸受負荷を調整できるため、円錐に構成されるために、円錐ジャーナルの製造は比較的費用がかかると云う課題が存在した。
本発明は、わずかな費用で組立ができ、軸受間隙および負荷の調整ができる印刷機シリンダ用の軸受を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、請求項１に記載された印刷機シリンダを支持するためのローラ軸受配置は、少なくとも３つの重合配置される軸受リングを有し、これらの軸受リング間で、少なくとも２セットのローラ体が転がる。その際、第１軸受リングは円筒形に構成されるレースウエイを有する。第１軸受リングと共に少なくとも第１セットのローラ体を収容する環状空間を構成する第２軸受リングは、円錐形に構成されるレースウエイを有する。環状空間内に配置される第１ローラ体は円錐形に構成される。
【０００８】
本発明によるローラ軸受配置は、簡単に組立ができ、間隙調整は非常に少ない費用で済むという長所を持つ。
【０００９】
また、請求項２に記載の発明において、前記第１ローラ体の円錐形状は凸曲線に重ね合せることができる。
【００１０】

【００１１】
また、請求項４に記載の発明において、前記第１ローラ体の端面が接触する軸方向停止面を備えた停止要素を設けることが長所である。
【００１２】
また、請求項５に記載の発明において、前記軸方向停止面は軸方向に運動できることを特徴とする。
【００１３】
また、請求項６に記載の発明において、前記停止要素は、第１軸受リングに対して同心に構成される内ねじに係合する外ねじを有することができる。
【００１４】
また、請求項７、８に記載の発明において、前記内ねじが一方の軸受リングに構成されると都合がよい。上記の構成部材により、第１ローラ体の軸方向の位置は所望の間隙を生じるように調整できる。その際、間隙調整は非常に簡単に実施され、他方、非常に正確に行うことができる長所を持つ。
【００１５】

【００１７】
また、請求項１１に記載の発明において、少なくとも２セットのローラ体を軸方向に並べて配置することができる。これは、同時に高い負荷容量でのシリンダの高精度な支持を実現できる長所を持つ。
【００１８】
【実施例】
本発明を図面で示す実施例に基づいて次に説明する。
【００１９】
図１は、２列のローラ体が重合配置される本発明による軸受配置の実施例を示す。このローラ配置は、内から外へ連続する第１軸受リング１と、第２軸受リング２と、第３軸受リング３と、第４軸受リング４とを有する。第１軸受リング１は印刷機シリンダのジャーナルを収容できる円筒孔５を有する。第１軸受リング１と第２軸受リング２との間で第１ローラ体６が配置される環状空間が構成される。ローラ体はケージ７で案内される。さらに、第３軸受リング３と第４軸受リング４との間で２列のローラ体８が配置される環状空間が構成される。ローラ体８はケージ９で案内される。
【００２０】
第１軸受リング１は内リングとして構成され、その外装面に、第１ローラ体６が転がる円筒形レースウエイ１０を有する。第２軸受リング２は外リングとして構成され、その内装面に円錐形レースウエイ１１を有する。もちろん、円錐角度は非常に小さく、円錐形状は図面で決して推測できない。第１ローラ体６は円錐形状に構成され、その際、円錐角度はレースウエイ１０、１１に適合される。第１ローラ体６の円錐形状は、特に、対数曲線の輪郭に従うわずかな凸曲面に重ねられる。それにより、作動特性が改善される。第１ローラ体６は大きい端面を備え、軸方向停止要素１３に構成される軸方向の停止面１２で軸方向に接触する。軸方向停止要素１３はリングとして構成され、第３軸受リング３内の内ねじ１５に係合する外ねじ１４を有する。軸方向停止要素１３の旋回により、軸方向停止面１２は軸方向へ移動できる。半径方向に対して鋭角に延びるねじ孔１７内に配置されるセットスクリュー１６により、軸方向停止要素１３は旋回に対して固定される。
【００２１】
第３軸受リング３は内リングとして役立ち、その内方外装面は第２軸受リング２の外方外装面に直接に当接する。使用状況に応じて、第３軸受リング３は第２軸受リング２と一体的に構成することもできる。第３軸受リング３は外方外装面で円筒形に構成されるレースウエイ１８を有する。潤滑剤により軸受配置の提供を簡単にするため、第３軸受リング３は潤滑剤の分配のための通路１９を有する。さらに、第３軸受リング３は偏心リングとして構成され、すなわち、第３軸受リング３の壁厚さは周辺に沿って変化し、第３軸受リング３の、それぞれの円筒形に構成される内外の外装面の中央軸線は符合しない。このようにして、第３軸受リング３の旋回により、印刷機シリンダのジャーナルを横に運動することができる。
【００２２】
第４軸受リング４は外リングとして構成され、その内方外装面に、同様に円筒形に構成されるローラ体８が転がる円筒形に構成されるレースウエイ２０を有する。第４軸受リング４の外方外装面は、同様に円筒形に構成され、ハウジング内への押し込みに適し、ハウジングはローラ軸受配置を収容し、固定する。第３軸受リング３と第４軸受リング４との間で、シール２１が配置され、潤滑剤漏れ、ごみ屑の入り込みを防止する。さらに、第４軸受リング４の両側には、ばねリング２２が配置され、ばねリングは、それぞれ、第３軸受リング３の半径方向溝内に係合し、軸方向の移動に対して第４軸受リング４を固定する。
【００２３】
図１に示される軸受配置の機能態様の特別な本質的観点は、第１軸受リング１、第２軸受リング２および第１ローラ体６の説明した構成により、第１軸受リング１、それで、全体の軸受配置、それで、軸受配置が押し込められるハウジングに関する第１軸受リングに収容されるジャーナルの軸方向の移動ができることにある。この移動にも拘わらず、この軸受部分内での間隙の調整ができることにある。このため、軸方向停止面１２を介して第１ローラ体６が軸方向へ移動され、第１ローラ体６および第２軸受リング２のレースウエイ１１の円錐構成のため間隙の減少または増加に至る結果、軸方向停止要素１３だけが旋回されねばならない。この間隙調整は第１軸受リング１、第２軸受リング２、第１ローラ体６により構成されるローラ軸受の多列構成の場合も対応した仕方ででき、この調整は、例えば、十分に高い負荷容量の達成に対しても必要なものとすることができる。
【００２４】
図２は、３列のローラ体が重合して配置される本発明による軸受配置の実施例を断面で示す。図２で図示する軸受配置の構成は、図１による軸受配置の一層の特徴に対応し、次に、特に、図１にはなく、または、変形した形状で図示される構造的特徴を詳細に説明する。半径方向の内部構造はローラ体８を含めて同じである。しかし、半径方向に続く第３軸受リング３に相違がある。この第３軸受リング３は第２軸受リング２に対して偏心リングとして構成される。他方、第３軸受リング３は中間リングとして構成され、すなわち、第３軸受リング３は、さらに、レースウエイ２０に対して、その内方外装面において、外方外装面でのレースウエイ２３を有する。このレースウエイ２３上で、ケージ２５により案内される２列の円筒形に構成されるローラ体２４が転がる。さらに、ローラ体２４は外リングとして構成される第５軸受リング２６上を転がり、このため、第５軸受リングは、その内方外装面にレースウエイ２７を有する。第５軸受リング２６は、ばねリング２８により軸方向で固定され、第４軸受リング４に対してシール２９により密封される。第５軸受リング２６の外方外装面は円筒形状の構成され、ハウジング孔への押し込みに適する。
【００２５】
機能態様および可能性のある変形に関して、図２で図示する実施例は、図１で実施されるものに当てはまる。
【００２６】
図示の実施例の変形では、第１軸受リング１、第２軸受リング２、第１ローラ体６から成る軸受は多列に構成され、すなわち、第１ローラ体６の２つ以上のセットを並列して配置できる。その際、軸受リング１または軸受リング２を軸方向で分離して実施することもできる。同様に、図示の２列軸受は適性に応じて一列軸受または２列軸受により置き換えることもできる。

[Problems to be solved by the invention]
However, since the bore of the inner bearing and the journal attached to the inner bearing can adjust the bearing load, and are configured as conical, there is a problem that the manufacture of the conical journal is relatively expensive.
SUMMARY OF THE INVENTION It is an object of the invention to provide a bearing for a printing press cylinder which can be assembled at a low cost and has adjustable bearing clearances and loads.
[0007]
[Means for Solving the Problems]
To this end, a roller bearing arrangement for supporting a printing press cylinder according to claim 1 has at least three overlapping bearing rings, between which at least two bearing rings. The roller body of the set rolls. In this case, the first bearing ring has a raceway configured in a cylindrical shape. The second bearing ring, which together with the first bearing ring forms an annular space for accommodating at least the first set of roller bodies, has a conical raceway. The first roller body disposed in the annular space has a conical shape.
[0008]
The roller bearing arrangement according to the invention has the advantage that it is easy to assemble and the clearance adjustment requires very little expense.
[0009]
Further, in the invention described in claim 2, the conical shape of the first roller body can be superimposed on a convex curve.
[0010]
In the invention described in claim 3, the convex curve can be dependent on the contour of a logarithmic curve. This has the advantage of improving the operating characteristics of the roller body.
[0011]
In the invention according to claim 4, it is advantageous to provide a stop element having an axial stop surface with which the end surface of the first roller body contacts.
[0012]
The invention according to claim 5 is characterized in that the axial stop surface can move in the axial direction.
[0013]
In the invention according to claim 6, the stop element may have an external thread that engages with an internal thread concentric with the first bearing ring.
[0014]
In the invention according to claims 7 and 8, it is convenient that the inner screw is formed in one of the bearing rings. With the above components, the position of the first roller body in the axial direction can be adjusted so as to produce a desired gap. In this case, the gap adjustment is very simple to carry out, while having the advantage that it can be performed very accurately.
[0015]
In the invention according to claim 9, at least one bearing ring of the roller bearing arrangement has an exterior surface eccentrically arranged with respect to each other. This has the advantage that the pivoting of this bearing ring can affect the lateral position of the cylinder supported in the roller bearing arrangement according to the invention.
[0016]
In the tenth aspect of the present invention, at least one set of cylindrical roller bodies can be provided in the roller bearing arrangement.
[0017]
According to the eleventh aspect, at least two sets of roller bodies can be arranged in the axial direction. This has the advantage that a highly accurate support of the cylinder with a high load capacity can be realized at the same time.
[0018]
【Example】
The present invention will be described below based on an embodiment shown in the drawings.
[0019]
FIG. 1 shows an embodiment of the bearing arrangement according to the invention in which two rows of roller bodies are superposed. This roller arrangement has a first bearing ring 1, a second bearing ring 2, a third bearing ring 3, and a fourth bearing ring 4 that continue from inside to outside. The first bearing ring 1 has a cylindrical bore 5 which can accommodate the journal of the printing press cylinder. An annular space in which the first roller body 6 is disposed is defined between the first bearing ring 1 and the second bearing ring 2. The roller body is guided by a cage 7. Further, between the third bearing ring 3 and the fourth bearing ring 4, an annular space in which two rows of roller bodies 8 are arranged is formed. The roller body 8 is guided by a cage 9.
[0020]
The first bearing ring 1 is configured as an inner ring, and has on its exterior surface a cylindrical raceway 10 on which the first roller body 6 rolls. The second bearing ring 2 is configured as an outer ring and has a conical raceway 11 on its interior surface. Of course, the cone angle is very small and the cone shape can never be inferred in the drawing. The first roller body 6 is configured in a conical shape, the cone angle being adapted to the raceways 10, 11. The conical shape of the first roller body 6 is, in particular, superimposed on a slightly convex curved surface following the contour of the logarithmic curve. Thereby, the operating characteristics are improved. The first roller body 6 has a large end face and comes into axial contact with an axial stop surface 12 formed on an axial stop element 13. The axial stop element 13 is configured as a ring and has an external thread 14 that engages an internal thread 15 in the third bearing ring 3. The pivoting of the axial stop element 13 allows the axial stop surface 12 to move axially. The axial stop element 13 is fixed against pivoting by a set screw 16 arranged in a screw hole 17 extending at an acute angle to the radial direction.
[0021]
The third bearing ring 3 serves as an inner ring, the inner facing of which directly abuts the outer facing of the second bearing ring 2. The third bearing ring 3 can be formed integrally with the second bearing ring 2 depending on the use situation. The third bearing ring 3 has a raceway 18 that is formed in a cylindrical shape on the outer exterior surface. In order to simplify the provision of the bearing arrangement by means of lubricant, the third bearing ring 3 has a passage 19 for the distribution of lubricant. Furthermore, the third bearing ring 3 is configured as an eccentric ring, i.e., the wall thickness of the third bearing ring 3 varies along the circumference, and the inner and outer cylindrically configured inner and outer portions of the third bearing ring 3. The central axis of the exterior surface does not match. In this way, the pivoting of the third bearing ring 3 allows the journal of the printing press cylinder to move laterally.
[0022]
The fourth bearing ring 4 is configured as an outer ring, and has on its inner exterior surface a raceway 20 configured in a cylindrical shape on which the cylindrical roller body 8 likewise rolls. The outer outer surface of the fourth bearing ring 4 is likewise cylindrically shaped and is suitable for pushing into the housing, which houses and fixes the roller bearing arrangement. A seal 21 is arranged between the third bearing ring 3 and the fourth bearing ring 4 to prevent leakage of lubricant and entry of dust. Furthermore, on both sides of the fourth bearing ring 4, spring rings 22 are arranged, each of which engages in a radial groove of the third bearing ring 3, and the fourth bearing ring against axial movement. Fix the ring 4.
[0023]
A special essential aspect of the functioning of the bearing arrangement shown in FIG. 1 is that the described configuration of the first bearing ring 1, the second bearing ring 2 and the first roller body 6 allows the first bearing ring 1, Bearing arrangement, so that the axial movement of the journal housed in the first bearing ring with respect to the housing into which the bearing arrangement is pressed can be achieved. Despite this movement, the gap in the bearing portion can be adjusted. For this reason, the first roller body 6 is moved in the axial direction via the axial stop surface 12, and the gap is reduced or increased due to the conical configuration of the raceway 11 of the first roller body 6 and the second bearing ring 2. As a result, only the axial stop element 13 has to be turned. This gap adjustment can be performed in a manner corresponding to the case of a multi-row configuration of roller bearings including the first bearing ring 1, the second bearing ring 2, and the first roller body 6, and this adjustment can be performed, for example, with a sufficiently high load. It may also be necessary to achieve capacity.
[0024]
FIG. 2 shows, in cross section, an embodiment of a bearing arrangement according to the invention in which three rows of roller bodies are arranged in an overlapping manner. The configuration of the bearing arrangement illustrated in FIG. 2 corresponds to a further feature of the bearing arrangement according to FIG. 1 and, in particular, details of the structural features not shown in FIG. explain. The internal structure in the radial direction is the same including the roller body 8. However, there is a difference in the third bearing ring 3 that continues in the radial direction. The third bearing ring 3 is configured as an eccentric ring with respect to the second bearing ring 2. On the other hand, the third bearing ring 3 is configured as an intermediate ring, that is, the third bearing ring 3 further has a raceway 23 on the inner outer surface thereof on the outer outer surface with respect to the raceway 20. . On this raceway 23, two rows of cylindrical roller bodies 24 guided by a cage 25 roll. Further, the roller body 24 rolls on a fifth bearing ring 26 configured as an outer ring, and therefore, the fifth bearing ring has a raceway 27 on its inner exterior surface. The fifth bearing ring 26 is fixed in the axial direction by a spring ring 28, and is sealed with respect to the fourth bearing ring 4 by a seal 29. The outer outer surface of the fifth bearing ring 26 has a cylindrical shape and is suitable for being pushed into the housing hole.
[0025]
In terms of functional aspects and possible variants, the embodiment illustrated in FIG. 2 applies to that implemented in FIG.
[0026]
In a variant of the embodiment shown, the bearing consisting of the first bearing ring 1, the second bearing ring 2 and the first roller body 6 is arranged in a multi-row, ie two or more sets of first roller bodies 6 are arranged in parallel. Can be placed. At that time, the bearing ring 1 or the bearing ring 2 can be separated from each other in the axial direction. Similarly, the illustrated double row bearing can be replaced by a single row bearing or a double row bearing as appropriate.
