Gauging Line for Gear Inspection

M62

M62 line of products includes a large variety of measuring instruments for dimensional and functional inspection of multiple types of gears. Utilizing highly precise tools and robust technology, Marposs solutions for gear verification offer the appropriate method of measurement to control the manufacturing process  in a shop floor environment.  All measuring systems are predisposed for the use of the Gear AddOn, a dedicated software for gear analysis compatible with Microsoft Windows®.

BENEFITS

RANGE OF APPLICABILITY

Marposs products for gear inspection offer the possibility to check different types of individual or assembled gears:

  • cylindrical gears
  • spur gears
  • helical gears
  • shafts gears
  • internal ring gears

VARIETY OF SOLUTIONS

The leading edge technology in design and engineering methods is applicable to manual gauges and  fully automated systems using dedicated or retoolable solutions depending on the specific demands of the gear production process.

ACCURACY and CAPABILITY

Based on years of experience, Marposs has defined accurate standards for the metrological quality of their gear measuring instruments that today represent the state of the art for evaluation of gear components.

DESCRIPTION

The M62 gear inspection line includes manual gauging instruments as well as automatic machines to match all the inspection requirements of the production process of a gear.

According to the specific operation along the process, Marposs can offer solutions to inspect:

  • Dimensional parameters: OBD, Pitch Diameter, Root Diameter, OBR, ID, Distances, Parallelism and Perpendicularity between surfaces and shape errors
  • Functional parameters: gear roller checks (Fi”, fi”, Fr”, Aa”, FTT, Nicks)

Depending on the gauge function, the measuring instrument is calibrated with artifacts (masters) that are of similar geometry to the production  gears inspected, or full part like artifacts in the case of functional gauging.

Marposs can offer a complete series of masters manufactured in standard gauge steel (62-64 HRC) or high speed tool steel (HSS) and with surface treatment like TiN coating.

All master gears are provided with certification as per DIN 3961-3962 specifications.

All the M62 gauging systems can be connected to a wide range of Marposs innovative electronic interfaces and industrial computers. Through the dedicated Gear AddOn software, compatible with Microsoft Windows® and Marposs QuickSPC™, it is possible to perform accurate gear analysis with the support of Cartesian and Polar graphic elaborations.
