Description

Håndrulle særlig for bånddrevne kjøretøyer. Hand roller especially for belt-driven vehicles.

Foreliggende oppfinnelse vedrører en The present invention relates to a

båndrulle, særlig for bånddrevne kjøre-tøyer, og hvis lengde er stor i forhold til diameteren, og av den type hvor et ytre rulleskall er lagret på en lagerhylse med et mellom skallet og hylsen innlagt fjærende materiale, og hvor lagerhylsen om-fatter to etter hinannen i aksial retning og i forhold til hinannen løstagbare deler. belt roller, in particular for belt-driven vehicles, and whose length is large in relation to the diameter, and of the type where an outer roller shell is stored on a bearing sleeve with a springy material inserted between the shell and the sleeve, and where the bearing sleeve includes two each other in the axial direction and in relation to each other removable parts.

Dette fjærende materiale — som van-ligvis består av gummi i form av en gum-mibandasje — har til formål å skaffe en avfjæring av deler som vanskelig kan av-fjæres på annen måte, såsom de deler av båndrullen som befinner seg innenfor rulleskallet, båndrullens aksel og eventuelt deler av akselens opphengningskonstruk-sjon. Det har vist seg at en sådan avfjæring i betydelig grad minsker slitasjen på båndrullens ikke avfjærede rulleskall. This springy material — which usually consists of rubber in the form of a rubber bandage — has the purpose of providing a suspension for parts that can hardly be suspended in any other way, such as the parts of the belt roll that are inside the roll shell, the belt roll's axle and possibly parts of the axle's suspension construction. It has been shown that such suspension significantly reduces the wear and tear on the non-suspended roller shell of the belt roll.

Oppfinnelsens formål er å skaffe en The object of the invention is to provide a

båndrulle av nevnte type, hvor rulleskallet kan utføres relativt tynt og dermed lett og hvor skallet kan utøve et kraftig aksialt trykk på hylsen uten at det fjærende materiale skades. tape roll of the aforementioned type, where the roll shell can be made relatively thin and thus light and where the shell can exert a strong axial pressure on the sleeve without damaging the resilient material.

Dette oppnås ved at de innbyrdes motstående flater på lagerhylsen og rulleskallet har stor konisitet nær båndrullens symmetriplan og liten konisitet nær båndrullens ender og har en sådan form at avstanden fra punkter på flatene og rullens geometriske akse er minst i det om-råde hvor lagerhylsens to deler forenes og øker mot båndrullens endeflater. This is achieved by the fact that the mutually opposite surfaces of the bearing sleeve and the roller shell have a large conicity near the symmetry plane of the belt roll and a small conicity near the ends of the belt roll and have such a shape that the distance from points on the surfaces and the geometric axis of the roll is smallest in the area where the two parts of the bearing sleeve unite and increase towards the end surfaces of the tape roll.

En utførelse av en båndrulle er i og for seg kjent, hvor den indre og den ytre rulledels motstående flater er utformet noe konisk, hvilket i det kjente tilfelle er gjort for å oppnå en sammenpressing av det mellom skallet og hylsen innlagte, fjærende materiale (gummi) i aksial retning. An embodiment of a belt roll is known in and of itself, where the opposite surfaces of the inner and outer roll parts are shaped somewhat conical, which in the known case is done to achieve a compression of the springy material inserted between the shell and the sleeve (rubber ) in the axial direction.

Oppfinnelsen skal beskrives nærmere i det følgende under henvisning til tegningen som viser et lengdesnitt av en ifølge oppfinnelsen konstruert båndrulle. På tegningen angir 1 en stasjonær aksel som er innrettet til å monteres i et bånddrevet kjøretøys understell. Faste løperinger 2 og 3 for to kulelagere kan oppta aksiale og radiale påvirkninger. De ytre løperinger for disse lågere har betegnelser 4 og 5 og bærer en lagerhylse som består av to halv-deler 6 og 7 som er innbyrdes forbundet ved hjelp av skruer 8. På lagerhylsen er der anordnet to mansjetter 9 og 10 som er av gummi og danner understøttelser for et rulleskall 11 som er lagret på lagerhylsen 6, 7. The invention will be described in more detail in the following with reference to the drawing which shows a longitudinal section of a tape roll constructed according to the invention. In the drawing, 1 indicates a stationary axle which is adapted to be mounted in a belt-driven vehicle chassis. Fixed races 2 and 3 for two ball bearings can absorb axial and radial influences. The outer race rings for these bearings have designations 4 and 5 and carry a bearing sleeve consisting of two half-parts 6 and 7 which are mutually connected by means of screws 8. On the bearing sleeve there are arranged two cuffs 9 and 10 which are made of rubber and form supports for a roller shell 11 which is stored on the bearing sleeve 6, 7.

For å flindre inntrengning av smuss og vann i kulelagrene er der anordnet tetninger 12 og 13 på akselen 1. Disse tetninger fastholdes ved hjelp av i forhold To prevent the ingress of dirt and water into the ball bearings, seals 12 and 13 are arranged on the shaft 1. These seals are held in place by means of

til akselen 1 faste tetningshylser 14 og 15 og tetningshylser 16 og 17 som fastholdes i forhold til lagerhylsen 6, 7 ved hjelp av skruer 18 og 19. to the axle 1 fixed sealing sleeves 14 and 15 and sealing sleeves 16 and 17 which are held in relation to the bearing sleeve 6, 7 by means of screws 18 and 19.

Rulleskallet 11 er utført av to symme-triske deler som er sammensveiset i et plan loddrett på rullens geometriske akse. The roller shell 11 is made of two symmetrical parts which are welded together in a plane perpendicular to the geometric axis of the roller.

Som vist på tegningen øker diameteren av de mot hinannen vendende flater av lagerhylsen og rulleskallet først sterkt (stor konisitet) til begge sider for et symmetriplan loddrett på rullens geometriske akse, og deretter mindre sterkt (liten konisitet). Ved denne utforming kan de mellom flatene anordnede gummimansj etter overføre betydelige påkjenninger uten å skades. As shown in the drawing, the diameter of the facing surfaces of the bearing sleeve and the roller shell first increases strongly (large taper) to both sides for a plane of symmetry perpendicular to the geometric axis of the roller, and then less strongly (small taper). With this design, the rubber sleeve arranged between the surfaces can transfer significant stresses without being damaged.

Når skallet 11 er slitt ut, kan det av-monteres ved at tetningen 12 med tilhø-rende tetningshylser 14 og 16 tas av, hvoretter kulelagrene med løperingene 2 og 4 fjernes. Derpå kan skruene 8 løses og la-gerhylsehalvdelen 6 trekkes ut. Det ned-slitte rulleskall 11 og gummimansj etten 10 kan tas av og nye mansjetter og nytt rulleskall settes inn, hvoretter rullens øvrige avmonterte deler settes på i omvendt rek-kefølge i forhold til den ved den beskrevne avmontering. When the shell 11 is worn out, it can be removed by removing the seal 12 with associated sealing sleeves 14 and 16, after which the ball bearings with the race rings 2 and 4 are removed. The screws 8 can then be loosened and the bearing sleeve half 6 pulled out. The worn-out roller shell 11 and the rubber sleeve 10 can be removed and new sleeves and a new roller shell inserted, after which the other dismantled parts of the roller are put on in the reverse order to that of the disassembly described.

Båndrulle for store radiale og aksiale belastninger, særlig for bånddrevne kjøre-tøyer, og hvis lengde er stor i forhold til diameteren, og av den type hvor et ytre rulleskall er lagret på en lagerhylse med et mellom skallet og hylsen innlagt fjærende materiale, og hvor lagerhylsen om-fatter to etter hinannen i aksial retning og i forhold til hinannen løstagbare deler, karakterisert ved at de innbyrdes motstående flater på lagerhylsen og rulleskallet har stor konisitet nær båndrullens symmetriplan og liten konisitet nær båndrullens ender, og har en sådan form at avstanden mellom punkter på flatene og rullens geometriske akse er minst i det om-råde hvor lagerhylsens to deler forenes og øker mot båndrullens endeflater. Belt roller for large radial and axial loads, especially for belt-driven vehicles, and whose length is large in relation to the diameter, and of the type where an outer roller shell is stored on a bearing sleeve with a springy material inserted between the shell and the sleeve, and where the bearing sleeve comprises two removable parts one after the other in the axial direction and in relation to each other, characterized in that the mutually opposite surfaces of the bearing sleeve and the roller shell have a large taper near the symmetry plane of the tape roll and a small taper near the ends of the tape roll, and have such a shape that the distance between points on the surfaces and the roll's geometric axis are smallest in the area where the two parts of the bearing sleeve join and increase towards the end surfaces of the tape roll.
