How Lead on Shafts Becomes Measurable with 3D Sensor Technology
Lead on shaft surfaces is a common cause of leaking in radial shaft sealing systems that is barely visible to the naked eye. The Surface/Lead Inspector from TGU Sealing Technology in Stuttgart measures it with the heliInspect H8 in just a few minutes, structure-based and according to FVA Guideline 975 I.
One method to measure this lead requires a sensor that delivers 3D topographies with micrometer resolution fast enough to capture an entire shaft in a reasonable amount of time.
This is where the Surface/Lead Inspector comes in. The shaft is mounted in the device and non-contact scanned under the sensor. The heliInspect H8 sensor from Heliotis is used. This is a white light interferometer that provides a complete 3D topography with micrometer resolution per scan.
The system covers all methods of the FVA Guideline 975 I. Because the heliInspect H8 captures height information across an area and in a single pass, the device can scan a dense measurement grid in axial and circumferential directions around the entire shaft, instead of scanning profile by profile. For manufacturing, this means: lead measurement no longer just as a random sample in the lab, but cycle-time-relevant in quality assurance.
The device accommodates shafts up to 200 mm in diameter, 380 mm in length, and 20 kg in weight, and at 600 × 700 × 900 mm and 70 kg, it is compact enough for use close to production. Easy-to-use measurement software guides through the measurement and creates the measurement report with the lead characteristics and a 3D visualization of the surface.
