Description

lOi 15 20 25 '30 35 759 (m5 'i 6 i i i 2 krosspringan 5 blir mindre. Genom att analogt avlägsna tryckmedíum _eur utrymmet.6, sjunker spindeln l nedåt och spindelkrossens inställ- ning blir större. lOi 15 20 25 '30 35 759 (m5 'and 6 i i i 2 the crusher 5 becomes smaller. By analogously removing pressure medium _eur the space.6, the spindle l sinks downwards and the setting of the spindle crusher becomes larger.

'För att i spindelkrossen möjliggöra den tvångsbetingadeisväng- "ningsrörelsen hos spindelaxelns 2a, 2b övre axeldel 2a har mellan 1spíndelaxelns delar 2a, Zbzanordnats trycklagerkombinationen H i enlighet med'Tiguren"2f Till trycklagerkomhinationen H hör mellan- plattan 7,1varsfövre yta 8 utgör en del av en konkavdsfärisk yta I och*mot vilken ligger spindelaxelns övre axeldels 2a undre ände 10, som har formen av en motsvarande konvex del av en sfärísk yta.

För jämförelse har i figur 3 uppvísats en tidigare känd konventionell trycklagerkombinatíon U"vid spindel- -axeln 2a', 2b"på en spindelkross, som avviker från den uppfinninge- enligaitrycklagerkombinationen H'på:så-sätt att i trycklagerkombina- tionen 4' är mellanplattans 7' undre glidyta 12 en planyta. I dylika :konventionella lösningar där undre ytan.l2av mellanplattan 7' i "trycklagerkombinationen U' är plan, är rörelsediagrammet för mellan- 'plattans 7' undre yta med avseende på spindelaxelns undre axeldel '2b*2..;3-faldig jämfört med rörelsediagrammet*för mellanplattans 7' övre yta med avseende nå spífidelaxelns övre axèIdel'2a.In order to enable in the spindle crusher the forced ice rotation The movement of the upper shaft part 2a of the spindle shaft 2a, 2b has between The parts 2a of the spindle shaft 2a, the thrust bearing combination H i is arranged according to 'Figure' 2f The thrust bearing combination H includes intermediate the plate 7,1of the upper surface 8 forms part of a concave spherical surface I and * against which lies the lower end portion 10a of the upper shaft portion 2a of the spindle shaft, which has the shape of a corresponding convex part of a spherical surface. The the lower surface 9 of the intermediate plate 7 of the thrust bearing combination U constitutes also part of a concave spherical surface, against which lies the spindle the lower end of the shaft, the upper shaft part '2b, which has the shape of a ~ corresponding convex part of a spherical surface. For comparison, Figure 3 shows a prior art conventional thrust bearing combination U "at spindle shaft 2a ', 2b "on a spindle crusher deviating from the invention according to the thrust bearing combination H 'in such a way that in the thrust bearing combination tion 4 ', the lower sliding surface 12 of the intermediate plate 7' is a flat surface. I dylika : conventional solutions where the lower surface.12 of the intermediate plate 7 'i "thrust bearing combination U 'is flat, the motion diagram of the the lower surface of the 'plate 7' with respect to the lower shaft portion of the spindle shaft '2b * 2 ..; 3-fold compared to the motion diagram * of the intermediate plate 7' upper surface with respect to the upper axis of the spi fi sub-axis'del'2a.

“Ilenlighet 'medTignr 2 är i den uppfinningsenliga trycklager- kombinationen U böjningsradien Bl för den övre konkava sfäriska yt- delen 8 påfmellanplattan 7 mindre än böjningsradien"R2 för den ned- re kønvexa sfäríska ytdelen 9 på mellanplattan 7. Genom att ändra förhållandet*Rl:R2 mellan böjningsradierna för mellanplattans 7 övre och nedre glidytor kan man påverka rörelsedíagrammen för mellan- plattans 7 övre och nedre glidytor. Lämp1igast'väljes böjningsradier- na R1 och R2.för mellanplattans 7 glidytor 8 och 9 så, att mellan- *plattans'7 rörelsesträckor med avseende på spindelaxelns övre del 2a eoch spindelaxelns nedre del 2b motsvara varandra såsom fallet är i exemplet i figur 2."Conformity" with Fig. 2 is in the pressure bearing according to the invention the combination U bending radius B1 for the upper concave spherical surface the part 8 on the intermediate plate 7 smaller than the bending radius "R2 for the lower re kønvexa spherical surface part 9 on the intermediate plate 7. By changing the ratio * R1: R2 between the bending radii of the upper plate 7 and lower sliding surfaces, one can influence the motion diagrams of intermediate the upper and lower sliding surfaces of the plate 7. Most preferably, the bending radius is selected. R1 and R2 for the sliding surfaces 8 and 9 of the intermediate plate 7 so that the intermediate * movement distances of the plate '7 with respect to the upper part 2a of the spindle shaft and the lower part 2b of the spindle shaft correspond to each other as is the case in the example in Figure 2.
