Limitations of conventional gear measurement techniques

Traditional gear inspection mainly relies on two-dimensional image measuring instruments, micrometers and other contact measurement tools. Although the image measuring instrument can realize non-contact detection, but limited by the two-dimensional imaging principle, the helix angle of the gear, tooth deviation and other three-dimensional parameters of the measurement of the blind spot. Micrometer measurement requires point-by-point contact measurement, single-parameter measurement takes as long as 20-30 minutes, and requires high operator skills.

POMEAS Multi-Sensor Measurement System redefines the industrial inspection standard with a revolutionary technology architecture in the era of “micron-level” precision manufacturing. The system deeply integrates the intelligent sensing capability of machine vision and the millimeter-level spatial resolution of 3D laser scanning to build a holographic inspection matrix covering “macro-appearance and micro-features”.

Relying on the self-developed heterogeneous sensor fusion algorithm, the system can synchronously capture 12 core parameters such as gear tooth profile, helix angle, tooth pitch deviation, etc., and complete the closed-loop inspection of full-size gears with modulus spanning 0.5-20mm in 180 seconds, with the measurement repeatability breaking through to ±1.5μm, which is an increase of 400% in the efficiency of the traditional inspection program and a jump of three orders of magnitude in the accuracy.
