Pitch gap at the junction (gear)

It always causes a clicking at the passage of the pinions; this difference is due to a defect of clamping or improper calibration. 2 cases are possible:

  • Negative pitch. The pitch between two teeth is smaller than the theoretical pitch of the girth gear.
  • Positive pitch. The pitch between two teeth is not greater than the theoretical pitch of the girth gear. This may be due either to excessive hold at the assembly or incorrect tightening.

Treatment of this type of fault can be done on site without dismantling, by on-site machining Novexa.
