Shimming, assembling

NOVEXA is becoming, year after year, a major player in the management of the wear of rotating tubes.
By now managing the supply, assembly and wedging, we are becoming a key player in the industry.

Replacement of wedges under bandages

As a specialist in machining and alignment control, our skills are also at your disposal to take up play under tires.
During our interventions, and transmitted in our report, we note :

  • Games under bandages before / after
  • Le voile faux rond
  • Shell deformation
  • Bandage thickness (regularity check).

Supply and assembly

Our skills revolve around:

  • Ability to supply wedges, cradles, hoops
  • Capacity to supply sprockets, crowns, tires (up to 3700 mm)
  • Reducer maintenance
  • Supervision of crown assembly and new tires provided by NOVEXA (based on validated plans)
  • Transmission of a technical report including plans and assembly dimensions

Correct adjustment is necessary

Correct adjustment is essential to avoid premature wear of equipment. We have noticed that in almost 90% of cases, precise adjustment would have avoided the development of damage.
The conditions for correct adjustment are :

  • Perfectly Cylindrical Bandages
  • Perfectly cylindrical pebbles parallel to the tires
  • Generators less than 0.04 mm flatness
  • Steering of 1 or 2 groups of rollers, on the ascent or descent, so as to obtain the minimum pressure on the thrust rollers

Roller adjustment

NOVEXA today offers the combined advantage of a know-how on gears, tires and alignment checks. Following the supply and/or replacement of shims, an alignment and setting check are necessary.

We thus define:

  • The levels of the massifs and the settings corresponding to the differences
  • The diameters of rollers and the values of shims necessary to compensate for the differences in axis levels
  • The deflections of the rollers intended to balance the tube and thus avoid excessive pressure on the stops
    The necessary modifications to be made to the gear settings if necessary (beat game et tooth bottom game)

We provide:

  • Shims calculated according to theodolite measurements
  • Hydraulic cylinders for lifting
  • The specifically trained workforce
  • The cradle

An adjustment and setting operation is entirely carried out by qualified NOVEXA personnel.
