Size Inspection Instruments
The diametral dimension over balls/pins is an important characteristic for gears and splines.
The diametral size is measured with opposed measuring inserts. Masters are used to set the nominal size. FRENCO offers a wide range of instruments for the size inspection. Ultimately, your batch size and test frequency defines the suitability of one or the other device. From simple manual instruments, through to automatic, process-integrated test equipment, FRENCO offers a custom-made solution. Basically, there are three types:
Your Contact
Manual Instrument for Small Batches
Rocking Type IVA and AVA
- Available for internal and external gears and splines
- Quick and easy test with two opposed measuring inserts
- Setting master with toothed sections available
- Cost-efficient solution for small batches
Manual Instrument for Small and Medium Batches
Instruments with Guiding Profile AVM and IVM
- Available for internal and external splines
- The guiding profile is matched to that of the workpiece to be inspected
- Due to the guiding profile, the dimension over balls can be established quickly and reliably
- Robust, simple and independent of the operator
- Fully toothed setting master available
Desk Instrument for Medium and Large Batches
Instruments with Guiding Profile AVM nx2, IVM nx2 and Tripod IVM 3x1
- Available for internal and external splines
- The guiding profile is matched to that of the workpiece to be inspected
- The dimension over balls is inspected within seconds at multiple positions at the same time
- Instead of measuring balls, radius discs are used to minimise wear
- The measuring electronics allows the evaluation of the diametral size along the tooth width
- Crowning and conicity are recorded
- Evaluation via FRENCO Software LdynPro
Size over two balls measurement: AVM 3x2 with horizontal sliding bench
- Easier handling for long workpiece shafts
- Fixed measuring plane within the longitudinal course
- Method 1: Repeatability for MdK averaged ≤ 1,3 μm
- Method 2: Tmin for MdK averaged = 18 μm (R&R ≤ 20%)
