<p>The rotary transmission has outer (5) and inner (9) fixed and rotatable (16,10) hollow cylinder sections, in pairs, form a first rotary transmission lead-through step. The slide surfaces (3,3') of the outer (16) and inner (9) hollow cylinder sections of the fixed part (2) are in contact with a slide surface (3',4') of the outer and inner (10) hollow cylinder section of the rotatable part (1). The slide surfaces have horizontal parallel annular ducts (6) connecting first (7) and second (12) inlets of the rotatable part with the first (8) and second (13) ducts of the fixed part. All the annular ducts (6,11) of two rotary transmission lead-through step surfaces have a top and bottom insulation (14,15) on the slide surface (3,4).</p> |
