Klingelnberg P 65

Tooth contact analysis is a computational simulation that predicts how the measured gear tooth surfaces will contact under load, based on the actual measured geometry of both the ring gear and pinion. TCA outputs include the contact pattern shape and location at different load levels, transmission error (a primary driver of gear noise), and load distribution across the tooth surface. On the P 65, TCA is performed automatically from the measured geometry, providing a prediction of the assembled gear set's noise and load performance without requiring physical assembly and testing.

The P 65 can physically measure the geometry of any bevel gear within its size envelope, including Gleason-format gears. However, the interpretation of results and the closed-loop correction workflow are optimized for Klingelnberg's own gear geometry definitions and KIMOS software format. Gleason-format gears measured on the P 65 can be reported in standard parameters, but the automated correction workflow with Gleason cutting machines is not natively supported.

Both are purpose-built bevel gear measuring machines. The P 65 integrates with Klingelnberg's KIMOS ecosystem and C-series cutting machines; the 350GMS integrates with Gleason's GEMS ecosystem and Phoenix cutting machines. The P 65's TCA and ease-off analysis capabilities are more advanced for engineering analysis; the 350GMS emphasizes production-line measurement throughput. Shops standardized on Klingelnberg cutting should specify the P 65; Gleason cutting shops should specify the 350GMS.

Klingelnberg specifies measurement uncertainty for the P 65 in compliance with VDI/VDE 2612 and 2613 standards for gear measuring instruments. At the P 65's size class, single-pitch deviation measurement uncertainty is typically in the range of 0.5-1.0 micrometers (0.0002-0.0004 in). Contact Klingelnberg or their calibration service for the specific measurement uncertainty values for the P 65 configuration and the gear geometry being measured.

The P 65 provides best accuracy in a temperature-controlled environment at 20°C ±1°C (68°F ±2°F) with vibration isolation. The integrated thermal compensation system extends the usable temperature range somewhat, but for highest accuracy (DIN 3-4 gear evaluation), a dedicated measurement space with climate control is recommended. Production floor installation is possible with reduced accuracy expectations and thermal compensation active.
