FIELD: agriculture; machine building.
SUBSTANCE: group of inventions relates to agricultural machine building. Set comprises flexible bus (5) having hollow chamber (25) and inner surface (51) around this hollow chamber (25). Flexible tire (5) also has a round hole in hollow chamber (25) and a pair of beads (35, 37), which are adjacent to this round hole and by means of which flexible tire (5) is installed around main part (3) of the wheel or support (102) of roller. Set also contains spacer (56), which is at least partially tubular (57) with two end surfaces opposite relative to axis. On at least one part corresponding to at least one of beads (35, 37), inner surface (51) passes as a whole in the form of a truncated cone, expanding in the radial direction towards the outer part of flexible tire (5), and at least one of the end surfaces of the spacer comprises at least one surface projecting in the axial direction. Spacer (56) has a suitable shape for its installation across the opening of flexible bus (5) so that protruding surface (63) is capable of engaging with inner surface (51) in the area of said part corresponding to (35, 37). Agricultural implement (1, 100) comprises main part (3) of wheel or roller support (102), flexible tire (5) having hollow chamber (25) and inner surface (51) around this hollow chamber (25). Flexible tire (5) also has a round hole in hollow chamber (25) and a pair of beads (35, 37), which are adjacent to this round hole and by means of which flexible tire (5) is installed around main part (3) of the wheel or support (102) of roller. Tool also comprises spacer (56), which is at least partially tubular with two end surfaces opposite relative to axis. On at least one part corresponding to at least one of beads (35, 37), inner surface (51) passes as a whole in the form of a truncated cone, expanding in the radial direction towards the outer part of flexible tire (5), and at least one of the end surfaces of the spacer comprises at least one surface projecting in the axial direction. Spacer (56) is installed across the opening of flexible bus (5) so that protruding surface (63) engages with inner surface (51) in the area of said part corresponding to bead (35, 37).
EFFECT: easy installation of the tire on the main part of the wheel or tubular support.
