Abstract

Disc screen rotor (1) comprising an axle (2) and a set of radially arranged discs (3) fixed onto the axle (2), concentric to its axis of rotation. The axle (2) has a cylindrical section, concentric to its axis of rotation, and which is provided with a set of grooves on its mantle, each of which extends around the whole of its circumference. At least one groove extends along the mantle of the cylindrical section parallel to the axis of rotation of the axle. Discs (3) having a hole, through which the cylindrical section is insertable, are mounted onto the cylindrical part and fitted into a respective circumferential groove in said cylindrical section, and fixed to the cylindrical section.

Description

506 921 2 Uppfinningen beskrives närmare i det följande i anslutning till bifogade ritningar, på vilka FIG. 1 är en perspektivisk ändy av en skivsållaxel avsedd för ett skivsåll, FIG. 2 är en sidovy av axeln i fig. l utan skivor, FIG. 3 är ett snitt genom axeln i fig. 2 taget i planet III - III, Samt FIG. 4 är en bortbruten, perspektivisk ändy motsvarande fig. 1 men visande en skiva under applicering. The invention is described in more detail in the following in connection with the accompanying drawings, in which FIG. 1 is a perspective end of a disc sieve shaft intended for a disc sieve, FIG. Fig. 2 is a side view of the shaft of Fig. 1 without discs; Fig. 3 is a section through the shaft of Fig. 2 taken in the plane III - III, and Fig. 4 is a broken away perspective view corresponding to Fig. 1 but showing a disc during application.

I fig. 1 visas en skivsållaxel l, som består av en axel 2 och en på denna placerad uppsättning skivor 3. Axeln 2 är vid båda ändar utförda med lagertappar 4 och icke närmare visade organ för driven rotation av skivsållaxeln 1. Skivorna 3 är koncentriska kring axeln 2.Fig. 1 shows a disc sole shaft 1, which consists of a shaft 2 and a set of discs 3 placed thereon. The shaft 2 is made at both ends with bearing pins 4 and not shown means for driven rotation of the disc sole shaft 1. The discs 3 are concentric around the shaft 2.

I fig. 2 och 3 visas axeln 2. Mellan lagertapparna 4 är axeln i form av en cylinder 5 med cirkulärt tvärsnitt och med större diameter än tapparna 4. I det visade utförandet är cylindern 5 rörformad. I cylinderns 5 mantelyta är spår 6 uppskurna runt hela dess omkrets. Dessa spår 6 är skurna med stor precision vad gäller position i cylinderns 5 längdriktning och vad gäller deras bredd. Ett antal längsgående spår 7, i det visade fallet fyra spår förskjutna 90 ° från varandra, sträcker sig från ände till ände av cylindern 5, parallellt med dess rotationsaxel.Figures 2 and 3 show the shaft 2. Between the bearing pins 4, the shaft is in the form of a cylinder 5 with a circular cross-section and with a larger diameter than the pins 4. In the embodiment shown, the cylinder 5 is tubular. In the mantle surface of the cylinder 5, grooves 6 are cut around its entire circumference. These grooves 6 are cut with great precision in terms of position in the longitudinal direction of the cylinder 5 and in terms of their width. A number of longitudinal grooves 7, in the case shown four grooves offset 90 ° from each other, extend from end to end of the cylinder 5, parallel to its axis of rotation.

Skivorna 3 har rent allmänt cirkulär form med ett centralt hål 8. Detta hål 8 har en form som motsvarar cylinderns 5 tvärsnitts- form, se fig. 3. Hålet 8, som i grunden är cirkulärt, har fyra radiellt inåt utskjutande element 9 svarande mot spåren 7.The discs 3 have a generally circular shape with a central hole 8. This hole 8 has a shape corresponding to the cross-sectional shape of the cylinder 5, see Fig. 3. The hole 8, which is basically circular, has four radially inwardly projecting elements 9 corresponding to tracks 7.

Monteringen av skivorna 3 på cylindern 5 tillgår så, att en skiva 3 i taget trädes över cylindern 5 till det spår 6, där skivan skall fästas. Där vrides skivan 3 så att de utskjutande elementen 9 kommer in i detta spår 6, vilken vridning i det visade utförandet är omkring 45°. Genom precisionen hos skivan 3 och på spåren 6 kommer skivan i ett axiellt riktigt läge. Skivan 3 kan 506 921 3 sedan fästas till cylindern 5 t.ex. genom svetsning, hårdlödning eller något annat passande förfarande.The mounting of the discs 3 on the cylinder 5 takes place in such a way that one disc 3 is stepped over the cylinder 5 at a time to the groove 6, where the disc is to be attached. There, the disc 3 is rotated so that the projecting elements 9 enter this groove 6, which rotation in the embodiment shown is about 45 °. Due to the precision of the disc 3 and on the grooves 6, the disc comes into an axially correct position. The disc 3 can 506 921 3 then be attached to the cylinder 5 e.g. by welding, brazing or any other suitable procedure.

När skivsàllaxlarna 1 sedan placeras i följd i skivsållmaskinen blir det inga inpassningsproblem, utan dessa samverkar direkt.When the disc sieve shafts 1 are then placed in succession in the disc sieve machine, there are no fitting problems, but these interact directly.

Man har sålunda genom denna uppfinning uppnått det inledningsvis ställda syftet.Thus, the initial object has been achieved by this invention.

Skivornas 3 utförande särskilt vad gäller den yttre omkretskanten så kan denna ha många olika utföranden i beroende av t.ex. det material som skall sållas. Antalet spår 7 i cylinderns 5 axialriktning kan också vara olika. Sådana variationer ligger dock inom uppfinningens grundtanke.The design of the discs 3, especially with regard to the outer circumferential edge, this can have many different designs depending on e.g. the material to be screened. The number of grooves 7 in the axial direction of the cylinder 5 can also be different. However, such variations are within the spirit of the invention.
