Description
Anordning ved kjefteknuseres tenner. Device at jaw crusher's teeth.
Ved knusemaskiner, særlig stenknusere In the case of crushing machines, especially stone crushers
med kjefteplater forsynt med tenner, er with jaw plates provided with teeth, is
disse sterkt utsatt for slitasje og når tennene er nedslitt under en viss grense må these are highly exposed to wear and when the teeth are worn down below a certain limit must
kjefteplatene eller iallfall den del som er the jaw plates or at least the part that is
forsynt med tenner utbyttes. provided with teeth are exchanged.
Kjefteplatene er vanligvis støpt av The jaw plates are usually cast off
høyprosentig manganstål, skjønt annet high percentage manganese steel, though different
materiale selvfølgelig kan komme til anvendelse. material can of course be used.
En hensikt med foreliggende oppfin-nelse er å øke kjefteplatenes, resp. tennenes One purpose of the present invention is to increase the jaw plates', resp. of the teeth
levetid. Tennene slites fra toppen slik at lifespan. The teeth are worn from the top so that
tannvinkelen stadig blir større. Ved å ut-forme tennene med kanaler ved fotsiden vil the tooth angle keeps getting bigger. By designing the teeth with channels at the foot side will
kjefteplatenes slitasje utjevnes. Kjeftepla-ten eller dens utskiftbare delers levetid vil the wear of the jaw plates is evened out. The life of the jaw plate or its replaceable parts will
derved forlenges. En annen hensikt med thereby being extended. Another purpose of
kanalen er at sten som er knust til støv fin-ner vei ut av knuseren så det ikke blir lig-gende mellom tennene og derved er med-virkende til ytterligere grusdannelse og the channel is that stone that has been crushed into dust finds its way out of the crusher so that it does not remain between the teeth and thereby contribute to further gravel formation and
derav følgende økt slitasje. resulting in increased wear and tear.
For nærmere å forklare oppfinnelsen To further explain the invention
vises til tegningen som skjematisk viser is shown to the drawing which schematically shows
tverrsnittet av to kjefteplater. Her er en av the cross section of two jaw plates. Here is one of
de to kjefteplaters tenner betegnet med 1. the teeth of the two jaw plates denoted by 1.
mens kanaler med forskjellig tverrsnittsform er vist ved 2, 3, 4, 5 og 6. Det vil for-stås at ved en kjefteplate vil en av disse while channels with different cross-sectional shapes are shown at 2, 3, 4, 5 and 6. It will be understood that in the case of a jaw plate one of these
tverrsnittsformer komme til anvendelse, cross-sectional shapes are used,
men det er intet i veien for at man ved but there is nothing in the way of knowing
samme kjefteplate anvender to eller flere the same jaw plate uses two or more
forskjellige tverrsnittsformer. Tverrsnittene different cross-sectional shapes. The cross sections
kan også endres i kanalens lengde enten i can also be changed in the length of the channel either i
areals størrelse eller form. area's size or shape.
De viste tverrsnitsformer er bare gitt som eksempler og kan varieres i overens-stemmelse med de forhold knuserne skal arbeide under. Likeså kan tennene utføres med smalere eller bredere basis i forhold til høyden avhengig om knuserne skal an-vendes som stenknusere, knokkelknusere eller liknende. The cross-sectional shapes shown are only given as examples and can be varied in accordance with the conditions under which the crushers must work. Likewise, the teeth can be made with a narrower or wider base in relation to the height, depending on whether the crushers are to be used as stone crushers, bone crushers or the like.
Den form som er vist av kanalene ved pkt. 4 i figuren hvor kanalen er utført med en fortrinnsvis plan bunn med innover mot hverandre skrånende vegger er å foretrekke. Her vil hjørnene 7 slites sam-men med tennene og derved vil tannflaten økes under nedslitningen således at leve-tiden ytterligere forlenges. Man har dog med prøver funnet at den i pkt. 6 viste form er å foretrekke. The shape shown by the channels at point 4 in the figure, where the channel is made with a preferably flat bottom with walls sloping inwards towards each other, is preferable. Here, the corners 7 will be worn together with the teeth and thereby the tooth surface will be increased during the wear and tear, so that the service life is further extended. However, tests have found that the form shown in section 6 is preferable.
