Manufacturing high-quality & precision gears involves careful consideration of various factors. GPI ensure the quality of our products by employing advanced measurement techniques. We discuss the crucial factors of a gear in the previous article. This article highlights the importance of key factors and the advanced measurement methods employed.

• 1. Outer Diameter/Inner Diameter/Tooth Thickness/HUB Dimensions

  • A. Significance:
    • Stability:In high-precision applications, strict control of dimension tolerances is crucial to ensure the stability of gears during assembly and operation. Dimensional control is also a key factor in guaranteeing the correct and reliable operation of high-precision gears, especially in demanding applications.
    • Assembly and Fit:Precise dimension control contributes to ensuring the correct fit of gears with other components.
  • B. GPI Measurement Methods:
    • Infrared Laser Scanner:Utilizing an infrared laser scanner to measure the maximum and minimum values of the outer diameter, obtaining the most accurate average outer diameter to ensure the stable diameter of each production lot.
    • Pin Gauges:For inner diameter measurements, various sizes of pin gauges which can meet the requirement of grade JIS4 are employed to ensure the accuracy of the inner diameter.
    • Height Gauge:Measuring HUB height to ensure consistent HUB dimensions.
    • 2.5D Measuring Instrument:Adopting advanced 2.5D measuring instruments for precise scanning of gear surfaces. This technology rapidly and accurately captures every detail on the gear surface, providing data on each distance, ensuring compliance with customer precision requirements, and integrating data into the database.

• 2. Profile/Runout of Outer Diameter

  • A. Significance:
    • Noise and Vibration:Excessive runout can impact the smooth operation of gears, affecting the overall efficiency of mechanical systems.
    • Durability:Precise gear profile design helps reduce wear and extends the lifespan of gears.
    • Transmission Accuracy:Runout of the outer diameter affects the accuracy of gear transmission. Excessive runout may lead to incorrect speed ratios, consequently affecting the operational efficiency of mechanical systems.
  • B. GPI Measurement Methods:
    • Runout Tester:Measuring the runout of gears/gear profile surfaces and recording the values, positions, and trends of runout. Data collected can be analyzed to evaluate the runout conditions of the outer diameter.

• 3. Pitch Error

  • A. Significance:
    • Smooth Operation:A small pitch error contributes to the smooth operation of gears, ensuring proper engagement of neighboring teeth, reducing vibration and noise in mechanical systems, and enhancing operational stability.
    • High Efficiency:In high-precision applications, a small pitch error helps ensure the efficiency of transmission systems by reducing energy losses, thereby improving transmission efficiency.
  • B. GPI Measurement Methods:
    • Disk Micrometer:Using a high-precision disk micrometer for pitch measurements. This method accurately measures the distance between neighboring teeth on the gear, calculating the pitch error. This step ensures that the manufactured gears have precise pitch distances, meeting strict customer requirements for operational stability and efficiency.
