Description

lO 15 20 25 30 35 517 960 I o o o ~ . . . n ~ | q q . | .. 2 Mera exakt är enligt uppfinningen den koniska hylsan försedd med isoleringsmaterial för att förhindra överföring av elektrisk ström genom lagret. lO 15 20 25 30 35 517 960 I o o o ~. . . n ~ | q q. | More precisely, according to the invention, the conical sleeve is provided with insulating material to prevent the transmission of electric current through the bearing.

Uppfinningen kommer i det följande att beskrivas med hänvisning till ett föredraget utföringsexempel, som visas i bifogade ritningar.The invention will be described in the following with reference to a preferred embodiment, which is shown in the accompanying drawings.

Fig. l illustrerar i tvärsnitt en avdragshylsa i enlighet med föreliggande uppfinning.Fig. 1 illustrates in cross section a pull-off sleeve in accordance with the present invention.

Fig. 2 visar i tvärsnitt ett rullager monterat med en avdragshylsa pà en axel i enlighet med föreliggande uppfinning.Fig. 2 shows in cross section a roller bearing mounted with a pull-off sleeve on a shaft in accordance with the present invention.

Fig. 3 illustrerar i tvärsnitt rullagret monterat på en axel via en klämhylsa i enlighet med föreliggande uppfinning.Fig. 3 illustrates in cross section the roller bearing mounted on a shaft via a clamping sleeve in accordance with the present invention.

Ett monteringsarrangemang indikeras generellt med J. och illustreras i. Fig. 2 och 3. .Arrangemanget 1. fixerar ett rullningslager 2 pä en axel 3 pà ett löstagbart sätt. Lagret 2 innefattar en innerring 2a och en ytterring 2b med ett antal rullkroppar 2c däremellan. Arrangemanget 1 omfattar en konisk hylsa 4 och organ 5 för att pressa hylsan 4 axiellt in mellan lagret 2 och axeln. Hylsan 4 är försedd med medel 6 för elektrisk isolering för att hindra överföring av elektrisk ström mellan lagret 2 och axeln 3.A mounting arrangement is generally indicated by J. and is illustrated in Figs. 2 and 3. The arrangement 1. fixes a rolling bearing 2 on a shaft 3 in a detachable manner. The bearing 2 comprises an inner ring 2a and an outer ring 2b with a number of roller bodies 2c in between. The arrangement 1 comprises a conical sleeve 4 and means 5 for pressing the sleeve 4 axially in between the bearing 2 and the shaft. The sleeve 4 is provided with means 6 for electrical insulation to prevent the transmission of electrical current between the bearing 2 and the shaft 3.

Den koniska hylsan 4, är t.ex. en avdragshylsa 4, som visas i Fig. 2 eller en klämhylsa 4', som visas i Fig. 3. Bàde klämhylsan 4' och avdragshylsan 4 har en konisk yta 6 riktad huvudsakligen radiellt utàt och en genomgående borrning, vilken i monterat läge anligger mot axeln 3. Bàda hylsorna 4, 4' kan också ha en axiellt förlöpande slits (ej visad) för att öka eller minska hylsans diameter vid nmntering lO l5 20 25 30 35 517 960 *i a n a Q o; 3 och/eller ansättning. Innerringen 2a pà lagret 2 är försedd med en inneryta som är konande i enlighet med den koniska ytan pä hylsan 4 och är riktad väsentligen radiellt inàt.The conical sleeve 4, is e.g. a pull-out sleeve 4, shown in Fig. 2 or a clamping sleeve 4 ', shown in Fig. 3. Both the clamping sleeve 4' and the pull-out sleeve 4 have a conical surface 6 directed substantially radially outwards and a through-bore, which in mounted position abuts against the shaft 3. Both sleeves 4, 4 'may also have an axially extending slot (not shown) for increasing or decreasing the diameter of the sleeve during assembly 10 l5 20 25 30 35 517 960 * iana Q o; 3 and / or employment. The inner ring 2a of the bearing 2 is provided with an inner surface which is conical in accordance with the conical surface of the sleeve 4 and is directed substantially radially inwards.

När den koniska hylsan 4 därför pressas eller tvingas in mellan axeln 3 och lagret 2 medför den en runtomgäende kil- formad montering.Therefore, when the conical sleeve 4 is pressed or forced in between the shaft 3 and the bearing 2, it results in a circumferential wedge-shaped assembly.

Enligt uppfinningen. är hylsan 4 försedd med isolerings- material 6 för att hindra överföring av elektrisk ström fràn axeln 3 till lagringen 2. Isoleringsmaterialet 6 skall vara tillräckligt starkt för att motstà de kraftiga kilkrafter, mellan axeln 3. Enligt som uppträder lagret 2 och uppfinningen, föredras en ytbeläggning 6. Det föredragna isoleringsmaterialet för beläggningen. 6 är' plasmasprutad aluminiumoxid.According to the invention. the sleeve 4 is provided with insulating material 6 to prevent the transmission of electric current from the shaft 3 to the bearing 2. The insulating material 6 must be strong enough to withstand the strong wedging forces, between the shaft 3. According to which the bearing 2 and the invention appear, a surface coating 6. The preferred insulation material for the coating. 6 is plasma sprayed alumina.

I det föredragna utföringsexemplet är isoleringsmaterialet 6 anordnat pà den koniska ytan pä hylsan 6. I alternativa (ej visade) utföringsexempel kan isoleringsmaterialet täcka den invändiga borrningen eller både borrningen och den koniska ytan pà hylsan.In the preferred embodiment, the insulating material 6 is arranged on the conical surface of the sleeve 6. In alternative embodiments (not shown), the insulating material may cover the inner bore or both the bore and the conical surface of the sleeve.

Alla stödanordningar för monteringsarrangemanget, som kan bringa lagret i elektrisk kontakt med axeln 3 mäste också vara isolerade. Exempel pà detta är tryckringen 7 i Fig. 2 och ansättningsmuttern 5' i Fig. 3. Dessa organ 7, 5' kan som helhet vara gjorda av elektriskt isolerat material eller kan vara isolerade pà vilket som helst av de ovan nämnda sätten.All support devices for the mounting arrangement, which can bring the bearing into electrical contact with the shaft 3, must also be insulated. Examples of this are the pressure ring 7 in Fig. 2 and the stop nut 5 'in Fig. 3. These members 7, 5' may as a whole be made of electrically insulated material or may be insulated in any of the above-mentioned ways.

Uppfinningen är inte begränsad till de i de bifogade ritningarna beskrivna och visade utföringsexemplen utan kan ramen för efterföljande modifieras och varieras inom patentkrav.The invention is not limited to the exemplary embodiments described and shown in the accompanying drawings, but the scope of the following can be modified and varied within claims.
