Description

Glr-Ûïtflfllfi I hus gjorda av gjutmetall eller liknande används ofta en låsbricka med tänder som trycks in mot maskinelementet. Glr-Ûït flfl l fi In houses made of cast metal or similar, a lock washer with teeth is often used which is pressed against the machine element.

Brickan låser då elementet mot axiella rörelser genom att tänderna gräver sig in i gjutmetallen och således spjärnar emot en axiell rörelse utåt. Vid plasthus är sådana brickor olämpliga, eftersom plasten är alltför mjuk och så småningom kommer att ge efter.The washer then locks the element against axial movements by the teeth digging into the cast metal and thus resisting an axial movement outwards. In plastic houses, such trays are unsuitable, because the plastic is too soft and will eventually give way.

Genom föreliggande uppfinning har man löst ovannämnda prob- lem och åstadkommit en anordning vid axiell fastsättning av ett maskinelement, såsom ett lager, i ett företrädesvis cylindriskt säte, huvudsakligen bestående av plast eller annat mjukt material och innefattande förstärkning i form av en stålspiral eller dylikt innanför ytan , vilken anord- ning kännetecknas av att axiella .spår är anordnade i plasten, vilka spår frilägger förstärkningen, och att en låsbricka 'med tänder är inpressad mot maskinelementet, varvid några av tänderna kommer till anliggning mot förstärkningen och därigenom låser brickan och maskinelementet mot axiella 'rörelser.The present invention has solved the above-mentioned problem and provided a device for axially fastening a machine element, such as a bearing, in a preferably cylindrical seat, mainly consisting of plastic or other soft material and comprising reinforcement in the form of a steel spiral or the like inside surface, which device is characterized in that axial grooves are arranged in the plastic, which grooves expose the reinforcement, and that a locking washer 'with teeth is pressed against the machine element, some of the teeth coming into abutment against the reinforcement and thereby locking the washer and the machine element against axial 'movements.

Uppfinningen kommer i det följande att förklaras under hänvisning till bifogade figurer, där figur 1 visar i snitt ett lagersäte med låsbricka enligt uppfinningen och figur 2 visar samma anordning sedd från vänster i figur 1.The invention will be explained in the following with reference to the accompanying figures, where figure 1 shows in section a bearing seat with lock washer according to the invention and figure 2 shows the same device seen from the left in figure 1.

'På figur 1 visas ett maskine1ement,1 som kan vara ytterringen av ett lager; som är infört i ett lagersäte 2 av plast.Figure 1 shows a machine element, 1 which may be the outer ring of a bearing; which is inserted in a bearing seat 2 of plastic.

Detta lagersäte 2 är förstärkt med en stålspiral 3, som ligger innanför den cylindriska ytan Ä hos huset. I huset 2 är axiella spår 5 anordnade. Dessa axiella spår 5 frilägger spiralen 3 på vissa ställen. Spårens antal runt periferien .'är icke kritiskt, men ett antal av sex stycken är lämpligt.This bearing seat 2 is reinforced with a steel spiral 3, which lies inside the cylindrical surface Ä of the housing. In the housing 2 axial grooves 5 are arranged. These axial grooves 5 expose the spiral 3 in certain places. The number of grooves around the periphery is not critical, but a number of six is appropriate.

' På figuren visas vidare en låsbricka 6 med fjädrande tänder 7.The figure further shows a locking washer 6 with resilient teeth 7.

När låsbrickan 6 har tryckts in mot maskinelementet 1 så kommer några av tänderna 7 att anligga emot spiraltråden 3, såsom visas på figuren. De kommer således att låsa maskin- elementet 1 mot rörelse åt vänster i figuren. 1:e* ' *vi --_---~ _ i .---..__--,s ._ 840214124: På figur 2 visas tänderna 7 vilka är införda i spåren 5 i plasten 2.When the lock washer 6 has been pressed against the machine element 1, some of the teeth 7 will abut against the spiral wire 3, as shown in the figure. They will thus lock the machine element 1 against movement to the left in the figure. 1st * '* vi --_--- ~ _ i. --- ..__--, p ._ 840214124: Figure 2 shows the teeth 7 which are inserted in the grooves 5 in the plastic 2.

Om så önskas, kan flera tänder 7 än spår 5 finnas. Tänderna 7 mellan spåren 5 kommer då att gräva sig in i plasten 2 och göra en begränsad nytta. Om emellertid standardbrickor används, som icke har samma antal tänder som de axiella spåren 5, kan således sådana brickor användas utan att de gör någon skada.If desired, more teeth 7 than grooves 5 may be present. The teeth 7 between the grooves 5 will then dig into the plastic 2 and make a limited use. However, if standard washers are used which do not have the same number of teeth as the axial grooves 5, such washers can thus be used without doing any damage.

Uppfinningen är icke begränsad till den visade utföringsformen utan kan på olika sätt modifieras inom patentkravens ram.The invention is not limited to the embodiment shown but can be modified in various ways within the scope of the claims.
