Abstract

The present invention relates to a vibration damping device for a bearing (2) arranged between a rotating shaft (3) and a bearing seat (4). The device comprises at least one solid body (1) which is arranged on or closely adjacent to an outer side of an outer bearing ring (5) forming part of the bearing (2) and which is so designed as to eliminate all or some of the vibrations propagated from the shaft (3) to the bearing seat (4) via the bearing (2) during operation. The invention also relates to a bearing device with such a vibration damping device, and methods for interruption of undesirable vibration transmission from a rotating shaft (3) to a bearing seat (4) via a bearing device supporting a shaft (2) by adaptation of the characteristics of the solid body (1). The present invention improves the possibility of dealing with vibrations which are propagated from a rotating shaft (3) to a machine body via a bearing (2).

Description

25 30 35 ffl i J \'3 ax: 2 utformas på många olika sätt. Masskroppen 1 är anordnad på eller i direkt anslutning till en i lagret 2 ingående yttre lagerrings 5 radiella yttersida. Den yttre Iagerringen 5 är inspänd och radiellt fixerad av lagersätet. Ett fixeringsmedel 7 på åtminstone ena sidan av den yttre Iagerringen 5 fixerar denna axiellt. Lagret har även en inre lagerring 9 vilken fixeras axiellt pà axeln 3 med ett fixeringsorgan 8. l en särskilt föredragen utföringsform avbildad i figur 1 är masskroppen 1 anordnad i en urtagning 6 i lagersätets 4 inre yta och är djupare än masskroppens 1 tjocklek t. Masskroppen 1 är en ring och urtagningen 6 är ringformig och anordnad utmed en inre periferi hos lagersätet 4. Ringen är löst spänd runt axeln 3 och är för att underlätta dess montering företrädesvis försedd med en slitsad öppning. 25 30 35 ffl in J \ '3 ax: 2 are designed in many different ways. The mass body 1 is arranged on or in direct connection with a radial outer side 5 of the outer bearing ring 5 included in the bearing 2. The outer bearing ring 5 is clamped and radially fixed by the bearing seat. A fixing means 7 on at least one side of the outer bearing ring 5 fi axes it axially. The bearing also has an inner bearing ring 9 which is fixed axially on the shaft 3 with a fixing member 8. In a particularly preferred embodiment depicted in Figure 1, the mass body 1 is arranged in a recess 6 in the inner surface of the bearing seat 4 and is deeper than the mass body t. 1 is a ring and the recess 6 is annular and arranged along an inner periphery of the bearing seat 4. The ring is loosely tensioned around the shaft 3 and is to be provided with a slotted opening to facilitate its mounting.

Masskroppen 1 kan vara homogen men kan också utefter sin omkrets uppvisa materialmässiga skillnader, såsom områden av olika bredd, tjocklek, material eller täthet eller en kombination av en eller flera av dessa egenskaper. Dessa parametrar används för att anpassa masskroppens 1 egenskaper för att få de under aktuella vibrationsförhàllanden lämpliga svängningsegenskaperna för att störa oönskade vibrationer i lagerkonstruktionen.The mass body 1 can be homogeneous but can also show material differences along its circumference, such as areas of different widths, thicknesses, materials or densities or a combination of one or more of these properties. These parameters are used to adapt the properties of the mass body 1 in order to obtain the oscillating properties suitable under current vibration conditions in order to disturb undesired vibrations in the bearing construction.

De materialmässiga skillnaderna kan utformas regelbundna utefter omkretsen eller oregelbundna beroende på de rådande vibrationsförhållandena. Densiteten hos materialet i masskroppen 1 kan motsvara den hos stål eller högre.The material differences can be designed regular along the circumference or irregular depending on the prevailing vibration conditions. The density of the material in the mass body 1 may correspond to that of steel or higher.

Vidare kan även masskroppens 1 spänning runt den yttre Iagerringen 5 anpassas för att under aktuella vibrationsförhàllanden få lämpliga svängningsegenskaperna för att störa oönskade vibrationer i lagerkonstruktionen. lstället för en ringformad masskropp 1 kan flera masskroppar vara anordnade utefter och pà lämpligt sätt anbringade vid den yttre lagerringens 5 radiella yttersida. Dessa kan vara lika utformade eller sins emellan uppvisa olika egenskaper vad gäller bredd, tjocklek, material eller täthet eller en kombination av en eller flera av dessa egenskaper. En sådan masskropp 1 kan istället utefter sin utsträckning längs den yttre lagerringens 5 periferi uppvisa varierande egenskaper vad gäller bredd, tjocklek, material eller täthet eller en kombination av en eller flera av dessa egenskaper.Furthermore, the tension of the mass body 1 around the outer bearing ring 5 can also be adjusted in order to obtain suitable oscillating properties under current vibration conditions in order to disturb undesired vibrations in the bearing construction. Instead of an annular mass body 1, your mass bodies can be arranged along and suitably arranged at the radial outer side of the outer bearing ring 5. These can be equally designed or have different properties in terms of width, thickness, material or density or a combination of one or more of these properties. Such a mass body 1 can instead, depending on its extent along the periphery of the outer bearing ring 5, have varying properties in terms of width, thickness, material or density or a combination of one or more of these properties.

Alternativt kan två eller flera ringformiga masskroppar anordnas parallellt i var sin urtagning i lagersätet 4. Dessa masskroppar kan dà utformas lika eller med olika egenskaper vad gäller bredd, tjocklek, material eller täthet eller en kombination av en eller flera av dessa egenskaper. En sådan ringformig massakropp kan i enlighet med föregående stycke naturligtvis bytas ut mot flera separata masskroppar anordnade utefter och på lämpligt sätt anbringade vid den yttre lagerringens 5 radiella yttersida.Alternatively, two or more annular mass bodies can be arranged in parallel in their respective recesses in the bearing seat 4. These mass bodies can then be designed equal or with different properties in terms of width, thickness, material or density or a combination of one or more of these properties. Such an annular pulp body can, of course, in accordance with the preceding paragraph, be replaced by its separate pulp bodies arranged along and suitably mounted at the radial outer side of the outer bearing ring 5.

Om den yttre lagerringens 5 infästning mot lagersätet 4 är sådan att Iagerringen 5 axiellt delvis skjuter ut utanför lagersätet 4 kan masskroppen eller masskropparna anordnas på en sådan del av Iagerringen 5. Masskroppen kan då exempelvis anligga mot en yta hos lagersätet som är vinkelrät mot axeln 3.If the attachment of the outer bearing ring 5 to the bearing seat 4 is such that the bearing ring 5 projects axially partially outside the bearing seat 4, the mass body or bodies can be arranged on such a part of the bearing ring 5. The mass body can then, for example, abut a surface of the bearing seat perpendicular to the shaft 3 .
