Pre \u0161tandardn\u00fd adendum \u0161pir\u00e1lov\u00e9 ozuben\u00e9 koleso<\/strong> pri norm\u00e1lovom uhle tlaku 20\u00b0 je vz\u0165ah medzi modulom, po\u010dtom zubov, uhlom \u0161pir\u00e1ly a vonkaj\u0161\u00edm priemerom:<\/p>\n

d_a = Mn \u00d7 (z + 2) \/ cos \u03b2<\/p>\n

Na vypo\u010d\u00edtanie Mn z nameran\u00e9ho d_a a vypo\u010d\u00edtan\u00e9ho z, usporiadajte tvar takto:<\/p>\n

Mn = d_a \u00d7 cos \u03b2 \/ (z + 2)<\/p>\n

V\u00fdzva: \u03b2 aj Mn s\u00fa spo\u010diatku nezn\u00e1me. Praktick\u00fd pr\u00edstup spo\u010d\u00edva v tom, \u017ee sa najprv odhadne \u03b2 z priameho merania (pozri krok 2), potom sa vypo\u010d\u00edta Mn a porovn\u00e1 sa s preferovan\u00fdm \u010d\u00edseln\u00fdm radom pod\u013ea normy ISO 54. Ak vypo\u010d\u00edtan\u00e9 Mn nie je presn\u00e9 preferovan\u00e9 \u010d\u00edslo, odhad \u03b2 sa mierne uprav\u00ed, k\u00fdm sa Mn nezhoduje s preferovan\u00fdm \u010d\u00edslom. Rie\u0161enie, ktor\u00e9 ud\u00e1va preferovan\u00fd modul (M2, M2,5, M3, M4, M5, M6, M8, M10, M12\u2026), je takmer ur\u010dite spr\u00e1vne.<\/p>\n

Nameran\u00fd vonkaj\u0161\u00ed priemer: d_a = 139,2 mm (meran\u00e9 posuvn\u00fdm meradlom v 3 poloh\u00e1ch, priemern\u00e1 hodnota)
\nPo\u010det zubov: z = 24 (spo\u010d\u00edtan\u00e9)
\nOdhadovan\u00e9 \u03b2 z priameho merania: ~20\u00b0<\/p>\n

Mn = 139,2 \u00d7 cos 20\u00b0 \/ (24 + 2) = 139,2 \u00d7 0,9397 \/ 26 = 130,8 \/ 26 = 5,03 mm<\/p>\n

\nOverte: d_a (teoretick\u00e9) = 5 \u00d7 (24+2) \/ cos 20\u00b0 = 5 \u00d7 26 \/ 0,9397 = 138,3 mm
\nRozdiel: 139,2 \u2212 138,3 = 0,9 mm \u2192 Toto je opotrebovanie hrotu zuba na p\u00f4vodnom ozubenom kolese. n\u00e1hradn\u00e9 \u0161pir\u00e1lov\u00e9 ozuben\u00e9 koleso<\/strong> je M5, z=24, \u03b2=20\u00b0.<\/p>\n<\/div>\n

Tip: Ak je vonkaj\u0161\u00ed povrch v\u00fdrazne opotrebovan\u00fd<\/strong>, opotrebovanie hrotu zuba umelo zni\u017euje nameran\u00fd vonkaj\u0161\u00ed priemer a m\u00f4\u017ee sp\u00f4sobi\u0165, \u017ee vypo\u010d\u00edtan\u00fd Mn sa bude javi\u0165 ako ni\u017e\u0161\u00ed ako skuto\u010dn\u00fd modul. Ak sa vypo\u010d\u00edtan\u00fd Mn nach\u00e1dza medzi dvoma preferovan\u00fdmi \u010d\u00edslami, zmerajte priemer kru\u017enice pa\u017enice d_f (vo vn\u00fatri pa\u017en\u00edc zubov pomocou h\u013abkomeru na meranie od vonkaj\u0161ieho priemeru ku pa\u017ei, potom d_f = OD \u2212 2 \u00d7 (meranie v\u00fd\u0161ky zuba)) \u2013 priemer pa\u017enice sa zvy\u010dajne neopotrebuje na hnac\u00edch bokoch a poskytuje spo\u013eahlivej\u0161\u00ed odhad modulu.<\/div>\n
