|Instruments for size inspection, face stop VP|
The diametrical dimension over balls of a specific measuring plane can easily and quickly be determined with a VPO measuring instrument. The instrument can be converted within minutes to a different diameter or from external to internal gearing.
|Technical data ||VPO 1 ||VPO 2 |
|External teeth up to ||100 mm pitch circle-Ø||200 mm pitch circle-Ø|
|Internal teeth up to||120 mm pitch circle-Ø||220 mm pitch circle-Ø|
|Measuring force progressively adjustable || up to 10 N |
|Dimensions (without stilts) ||185 x 58 x 180 mm ||340 x 118 x 210 mm|
The diametrical dimension over balls in as many measuring planes as required can quickly be determined with a VPE instrument. The instrument can be converted within minutes to a different diameter and from external to internal gearing.
|Technical data ||VPE |
|External teeth up to ||200 mm pitch circle-Ø|
|Internal teeth up to||220 mm pitch circle-Ø|
|Longitudinal travel||30 mm |
|Dimensions (without stilts)||340 x 118 x 210 mm|
We recommend using our software package LDYN to evaluate and increase the informational value of the measurement results.
The VPS instrument, the latest development in this product line, is a further development of the successful inspection instrument line VPO/VPE and is especially suitable for big and heavy test items. Great importance was given to functionality, optical characteristic, an ingenious design and optimum ergonomics to make sure that besides precision and accuracy, a comprehensive objective was achieved. The VPS is easy to operate and a stable tabletop instrument to be used on the shop floor.
Just like VPO and VPE instruments, the VPS is used for size inspections of gearing and is suitable for both internal and external gearing as well as for spur and helical gearing.
| Technical data ||VPS |
| Workpiece with external teeth ||0 - 350 mm pitch circle-Ø|
|Workpiece with internal teeth|| 55 - 350 mm pitch circle-Ø |
|Max. vertical travel||75 mm |
| Max. workpiece weight ||20 kg |
| Max. measurement error ||±3µ |
| Repeatability ||±3µ|
The VPS has, unlike the VPE, a fixed workpiece support on which both measuring stilts are vertically movable. The vertical travel is 75mm. In order to position heavy workpieces easily for inspection with double flank contact, workpieces can be supported on air cushions.
We also recommend the software package LDYN for evaluation of VPS measuring results.
Longitudinal dynamic evaluation LDYN:
VPE and VPS measuring instruments can be upgraded for dynamic inspections. The vertical travel of the table (VPE) or of the measuring stilts (VPS) are assigned to a measured value and saved. Several hundred vertical sections are possible and can be evaluated with this longitudinal scanning method. The upgrade requires both mechanical and electronic components, plus the software.
