Gear Rolling Testers are used to evaluate the accuracy and performance of gears by actually meshing and rotating them.
Gears are used in a wide range of fields for power transmission, and their quality greatly affects the performance and durability of the entire product. Even if a gear is manufactured according to drawings, it is meaningless if it does not operate smoothly when actually used. Gear Rolling Testers are used to evaluate gears while reproducing actual meshing conditions.
The standard testing method is to mesh a high-precision master gear with the gear to be tested and measure its movement while rotating both gears. In this process, slight tooth profile errors, pitch errors, eccentricity, and other errors are manifested in the form of load fluctuations, vibration, noise, and so on. The tester records these phenomena as numerical values and graphs to determine quality.
The applications of Gear Rolling Testers can be broadly divided into the following categories. 1.
In the manufacturing industry, gear meshing testers are used for quality assurance of products. Gears are the heart of a machine, and the slightest deviation in accuracy can lead to a malfunction of the entire machine. By conducting meshing tests during the final inspection of the manufacturing process, we confirm that the gears to be shipped can guarantee stable operation.
Research and development is another area where Gear Rolling Testers are utilized. In the design and development of new gear shapes and materials, testing machines are used to understand actual meshing behavior that cannot be determined by theory or simulation alone. For example, when aiming for lower noise and higher efficiency, it is important to measure the effects of tooth profile modification and differences in lubrication conditions.
Gear Rolling Testers are also used for durability and reliability evaluation. Gears can be subject to wear and tear over long periods of operation, and understanding their behavior in advance is fundamental to reliability design. Gear Rolling Testers can be used to analyze endurance limits and failure modes by varying loading conditions and operating gears for extended periods of time.
