FIELD: metallurgy.
SUBSTANCE: claimed drive comprises toothed swivel spindle (3) arranged to displace axially and extending the toothed swivel (50) fitted in the gear engagement chamber (20) from the side of rolls and toothed swivel (52) located in gear engagement chamber (40) from the side of reduction gear. One of said chambers (20, 40) is filled with grease. Claimed drive can be squeezed by the grease of spindle (3) at axial force (FWS) toward the rolls side (WS). Note here that said spindle (3) has the first working surface (AWS) located in the gear engagement chamber (20) from the side of rolls and second working surface (AGS) located in the chamber (40) from the side of reduction gear. Note here that said first and/or second working surface (AWS, AGS) are loaded by the grease. At least the chamber (40) is sealed from the side of reduction fear against the grease.
EFFECT: higher reliability.
