  • AGMA Quality Rating
    The American Gear Manufacturers Association (AGMA) publishes quality-level standards for gears based on pitch variation, profile error, and tooth alignment accuracy. Quality levels are defined in the AGMA 2000-A88 Gear Classification and Inspection Hand Book. In general, higher quality levels
  • Reconditioning Large Gears
    for material integrity the rim thickness, tooth thickness, tooth size, and wear to the teeth are measured to estimate whether or not the gear blank is a candidate for reconditioning. Essentially, is there is material enough for generating a new tooth?. Calculations derived from AGMA Standards

    undercutting. Shortest distance between the noncontacting surfaces of the adjacent teeth. Gears are commonly specified according to AGMA Class Number, a code which denotes important quality characteristics. Quality numbers denote tooth-elements tolerances. The higher the number, the tighter the tolerance

  • Applying Open Gear Lubricants
    inspections must be made to ensure that a sufficient amount of open gear lubricant is being applied to provide proper protection. Two hours is the maximum interval time permitted between applications per the AGMA 9005-D94 guidelines. The amount of open gear lubricant to use is dependent upon
