Description
l.7so1í47-5 en konisk yta övergår i en inre, central del, vilken är försänkt i förhållande till skivan och vilken åtminstone delvis är utformad som en kapa avsedd att täcka en ände av den axel som uppbär risten. A conical surface merges into an inner, central part, which is recessed relative to the disc and which is at least partially formed as a cap intended to cover one end of the shaft supporting the grate.
Uppfinningen kommer nu att beskrivas närmare med hänvisning till bifogade ritning, på vilken fig. 1 visar ett snitt genom en skivrist enligt uppfinningen upphängd pa en arrh och fig. 2 är en skuren planvy av risten.The invention will now be described in more detail with reference to the accompanying drawing, in which Fig. 1 shows a section through a disc grating according to the invention suspended from a rail and Fig. 2 is a cut plan view of the grating.
Skivristen betecknas generellt med 1D och har en central, uppskjutande del 11, som via en konisk del12 överger i en yttre, ringformad del13. Dalen 13 har ett antal trappstegeformade sektorer' 14, vilkas uppgift är att öka friktionen mot marken, så att risten far den nödvändiga självrotationen. Det centrala uppskjutande partiet ll har vid sin mitt en tallrikaformad del 15, avsedd att tjänstgöra som lock över ändan av en axel 16, pa vilken risten är lagrad. Det centrala partiet har vidare ett antal hal 17, genom vilka bultar 18 sträcker sig och haller fast risten vid en fläns av en yttre, i snitt L-formad lagerdel 19. Flänsen är försedd med en yta 20, mot vilken den koniska delen 12 anligger och centrerar risten. Flänsen har också en mot det centrala partiet 11 vettande yta 21 med en fördjupning 22 inneslutande en 0-ring 23, som tjänstgör som tätninga- element mellan risten och lagerdelen. Den L-formade lagerdelen: 19 andra fläns stödes upp av tva kullager 24, 25, som är anbragta pa axeln 16 och kvarhalles på axeln och i lagerdelen med làsringar 26. Pa grund av tätningsringen 23 och anliggningen mellan ristens koniska del 12 och den yttre lagerdelens yta 20 erhålles en tät och bra förbindning. Det av j kullagren 24, 25 och lagerdelen 19 bildade lagret är via ett konventionellt tätningsarrangemang avskilt fran omgivningen. Axeln 16 är upphängd i en arm 27, som i sin tur uppbäres av plogramen omedelbart framför varje plogkropp.The disc grating is generally denoted by 1D and has a central, projecting part 11, which via a conical part 12 merges into an outer, annular part 13. The valley 13 has a number of step-shaped sectors' 14, the task of which is to increase the friction against the ground, so that the grate has the necessary self-rotation. The central projecting portion 11 has at its center a plate-shaped part 15, intended to serve as a lid over the end of a shaft 16, on which the grate is mounted. The central portion further has a number of halves 17, through which bolts 18 extend and hold the grate to a flange of an outer, in section L-shaped bearing part 19. The flange is provided with a surface 20, against which the conical part 12 abuts and centers the grate. The flange also has a surface 21 facing the central portion 11 with a recess 22 enclosing an O-ring 23, which serves as a sealing element between the grate and the bearing part. The L-shaped bearing part: 19 second flange is supported by two ball bearings 24, 25, which are mounted on the shaft 16 and are retained on the shaft and in the bearing part with locking rings 26. Due to the sealing ring 23 and the abutment between the conical part 12 of the grate and the outer the surface 20 of the bearing part is obtained with a tight and good connection. The bearing formed by the ball bearings 24, 25 and the bearing part 19 is separated from the surroundings via a conventional sealing arrangement. The shaft 16 is suspended in an arm 27, which in turn is supported by the plogram immediately in front of each plow body.
Skivristens periferi ligger i linje med kullagret 25, och därför kommer den radiellt riktade kraft som uppträder vid ristens arbete i marken att direkt överföras till kullagret 25 via lagerdelen 19. Detta innebär en fördel jämfört med ett tänkt utförande där risten är placerad pa sidan om kullagret, i vilket fall förutom de radiellt riktade krafterna relativt stora böjande moment maste upptagas av lagren.The periphery of the disc grate is in line with the ball bearing 25, and therefore the radially directed force which occurs during the work of the grate in the ground will be transmitted directly to the ball bearing 25 via the bearing part 19. This is an advantage compared to an imaginary embodiment where the grate is located , in which case, in addition to the radially directed forces, relatively large bending moments must be absorbed by the bearings.
Uppfinningen är givetvis inte begränsad till den visade och beskrivna utförings- formen utan kan modifieras inom ramen för efterföljande patentkrav.The invention is of course not limited to the embodiment shown and described but can be modified within the scope of the appended claims.
