Analysis of Gear Inspection Content and Standards

Gears refer to mechanical parts with teeth that can mesh with each other, and their transmission can complete functions such as acceleration, deceleration, and direction change. They are widely used in mechanical transmission and the entire mechanical field. Gear inspection is a key link in ensuring the performance and quality of gear products, an important acceptance basis in the acceptance process of finished products, and also a technical guarantee for quality control in the gear manufacturing process. Regarding gear inspection knowledge, JEENOCE will briefly introduce it to you today.

What data is required for gear inspection:

1. Tooth profile: tooth shape error, tooth slope error, and total tooth shape error;

2. Helix: tooth shape error, tooth slope error, and total tooth error;

3. Other parameters: individual pitch error, cumulative pitch error, tooth thickness, runout, tilt angle, etc.

4. System functions: automatic positioning and clamping, automatic establishment of coordinate system, automatic generation of measurement path, one click detection, automatic identification of qualified parts, and customized report output.
