Samosvorn\u00e9 vs. s mo\u017enos\u0165ou sp\u00e4tn\u00e9ho pohonu<\/h3>\n

Pri prevodov\u00fdch pomeroch 30:1 a vy\u0161\u0161\u00edch je z\u00e1vitovkov\u00e1 prevodovka RV\/NMRV samosvorn\u00e1: bremeno nem\u00f4\u017ee za statick\u00fdch podmienok pos\u00fava\u0165 z\u00e1vitovkov\u00fd hriade\u013e cez ozuben\u00fd z\u00e1ber. V\u010faka tomu je prevodovka vhodn\u00e1 pre pohony \u0161ikm\u00fdch dopravn\u00edkov a polohovacie aplik\u00e1cie bez samostatnej brzdy. Pri prevodov\u00fdch pomeroch pod 30:1 (5:1, 7,5:1, 10:1, 15:1, 20:1) je prevodovka sp\u00e4tne poh\u00e1\u0148an\u00e1.
