With measurement technology to a closed loop

Gears are frequently used and important mechanical parts whose quality has a direct impact on the durability and safety performance of the machines in which they are installed.

Sinergy Gearing Technology Co., LTD from Nanjing, China, specializes in the processing and sale of high-precision gears. These are mostly used in wind power, steel industry, metallurgy, building materials industry and petrochemicals, etc.

As these markets have grown rapidly in recent years, quality testing of large transmissions has become increasingly important. Sinergy's customers are mainly located in Europe, where there are very strict requirements for the quality of the products. In response, Sinergy has consistently maintained high standards. After detailed communication and comparisons with other measuring machine manufacturers and experts in the industry, Sinergy opted for a large, high-precision coordinate measuring machine with portal design LHF 3020 by WENZEL.

“We use the WENZEL LHF not only to measure the gears, but also to measure the “pin hole” and many positions as well as geometric features to achieve a closed-loop process”

Sinergy's high-precision gearboxes are widely used in large wind turbines in China and other countries. It goes without saying that the quality of the transmission is of great importance for wind turbines. That is why Zhu Baojun, managing director of Sinergy, has high expectations and many requirements for the measurement device: “As a manufacturer of large-format wind power transmissions, we not only have to measure the geometric dimensions of the product, but also the technical indicators associated with the transmission, such as the diameter pitch, the profile angle and the modification in the product measurement process. We need combined measuring devices that can perform gear inspection and professional coordinate measurement and provide reports and data that are compatible with major international technical standards. After preliminary investigations and extensive, thorough technical exchange, we have learned that WENZEL is the best manufacturer of professional coordinate measuring machines and professional gear measuring devices in the industry. After careful consideration, Sinergy chose the WENZEL LHF 3020 because it meets our product measurement requirements. The measurement covers all important technical indicators of 6 MW wind power transmissions and provides measurement reports that our customers recognize. ”

Before Sinergy introduced the WENZEL LHF 3020, one of its products had to be measured on two different devices. For example, the position of the “pin hole” was measured on the traditional coordinate measuring machine and the gearing accuracy of the internal gearing was measured on the gear measuring machine. In comparison, with WENZEL CMG, Sinergy can create a pin hole report, a position report and a gearing report (including gear pitch, diameter pitch, profile slope) on the same processing standard and the same measurement standard and also generate two measurement reports on the same processing benchmark, which had to be done on two different devices in the past.

The WENZEL LHF 3020 combines coordinate measurement and gearing measurement in one device and uses the measurement module WM | GEAR in the new measurement software World Cup | Quartis, which carries out professional gear measurement as well as the analysis and evaluation of the measurement results. Equipped with WENZEL's unique measurement compatibility, the LHF can not only carry out the professional measurement of gears, but also the coordinate measurement of geometric parts. By integrating the functions of a gear measuring machine and coordinate measuring machine in one device, WENZEL KMG Sinergy helps to minimize labor, time and capital costs, adopt the same measurement standard and reproduce the gear design on this device.

Closed-loop regulations to improve efficiency

Sinergy's industrial layout focuses on regulation, which plays a crucial role in ensuring the stability and reliability of mass production. “With WENZEL LHF, we can carry out offline measurements in the same production cycle at a specific frequency and achieve maximum product stability. We can use it not only to measure gear processing, but also to process the “pin hole” and many positions as well as for geometric precision processing to achieve closed-loop control. This is very helpful for us to win new orders from customers as we continue to work together,” explains Zhu Baojun.
