PORTABLE CMM GEAR INSPECTION

On-Site & Incoming Gear Measurement and Inspection for Large and Critical Gears

Inspect Gear provides advanced portable CMM gear inspection software for accurate on-site and incoming inspection of spur, helical and spline gears. Using articulated arm portable CMM systems combined with a guided inspection workflow, large gears can be inspected either in situ or during incoming quality inspection, eliminating the need for full disassembly or transport to a metrology laboratory in many cases.

This approach significantly reduces downtime, lowers inspection cost, and enables faster engineering decisions during shutdowns, overhauls and component receipt inspections.

Suitable for Large, Installed and Incoming Gears

Portable CMM inspection is ideal for gears that are:

  • Too large or heavy to transport
  • Installed in gearboxes, mills or drives
  • Part of critical production equipment
  • Received as new or refurbished components requiring incoming inspection
  • Required to be inspected during shutdowns

Typical applications include:

  • Mining gearbox gears
  • Mill and crusher gears
  • Power generation gearbox gears
  • Heavy industrial transmission systems
  • Incoming inspection

Guided Gear Inspection Workflow

Inspect Gear software integrates with PolyWorks and portable CMM systems to provide a guided inspection process:

  • Structured measurement sequences for consistent results
  • Controlled alignment and datum strategies
  • Real-time deviation review
  • Calculation of key gear parameters
  • Standardised inspection reporting

This reduces operator variation and improves repeatability and confidence in inspection results.

Measurement Methods

The software supports two proven measurement approaches:

Probe-Based Measurement

Direct probing of gear tooth flanks using the correct stylus configuration for high accuracy. This method is recommended where maximum precision is required and appropriate probe sizes are available.

Measurement Pin Method

Use of calibrated measuring pins to access gear geometry where direct probing is not available.

Both methods are fully supported within the software workflow.

Reverse Engineering

In addition to inspection, the system supports gear reverse engineering, enabling:

  • Capture of gear geometry for legacy or undocumented gears
  • Creation of manufacturing reference data
  • Validation of replacement gear designs

Benefits for Mining & Heavy Industry

Using portable CMM gear inspection with Inspect Gear software delivers:

  • Reduced equipment downtime
  • Improved incoming inspection confidence
  • Reduced risk of installing non-conforming gears
  • Faster inspection turnaround
  • Improved maintenance and overhaul planning
  • Increased confidence in gear condition assessment

Designed for Field and Workshop Use

The solution is designed for both field and workshop environments:

  • Supports large and heavy gears
  • Works in confined and industrial environments
  • Suitable for shutdown and overhaul projects
  • Suitable for incoming inspection in workshops and stores
  • Optimised for maintenance, reliability and quality teams
