Hangzhou Gear’s new Transmission Technology Products Debut at the Science and Technology Festival

From May 16 to 17, 2024, at the Engineering Machinery Industry Science and Technology Festival (hereinafter referred to as the Science and Technology Festival) jointly sponsored by the China Engineering Machinery Industry Association and the Institute of High-end Equipment of Zhejiang University, the exchange area of ​​Hangzhou Qianjin Gearbox Group Co., Ltd. (hereinafter referred to as Hangzhou Gear) attracted the attention of many participants, and industry professionals showed great interest in the gear transmission technology and powder metallurgy products on display. As a large enterprise in my country that specializes in the design and manufacture of gear transmission devices and powder metallurgy products, Hangzhou Gear has attracted much attention at this exhibition.

At this Science and Technology Festival, Hangzhou Gear demonstrated its deep technical innovation capabilities and brought a series of high-end products. Among them, the EDB24 dual-input high-speed drive assembly is particularly eye-catching. The assembly adopts dual-motor direct input and uniquely integrates the hydraulic power take-off system and the transmission travel system. This innovative design is a major technological breakthrough of Hangzhou Gear in the field of electric drive loaders. Under the current trend of advocating environmentally friendly and efficient engineering machinery development, this dual-motor drive mode can effectively improve energy utilization efficiency, reduce dependence on traditional fuels, and provide strong support for the green development of engineering machinery.

And the WG180 hydraulic transmission, its “W” represents the first letter of the German torque converter, “G” represents the first letter of the German transmission, and “18” represents the transmission capacity of about 180kw. With its efficient transmission performance, this product can accurately transmit the power of the engine to each working part of the engineering machinery to ensure the stable operation of the equipment. In addition, its excellent control technology can adjust the transmission parameters in real time according to different working conditions to meet the complex and changeable power transmission needs of different engineering vehicles. For example, when the loader is performing heavy-load operations, it can provide powerful and stable power output to ensure efficient operation. ​

The YD130 hydraulic transmission, which has also attracted much attention, “Y” represents the hydraulic torque converter, “D” represents the fixed-shaft structure, “13” represents the transmission capacity of about 130KW, and “0” represents the long center distance of 500mm. It consists of a hydraulic torque converter, an intermediate shaft speed change structure and a hydraulically controlled multi-plate friction clutch, with a variety of forward and reverse gear models to choose from. Its torque converter adopts a three-element structure, that is, the pump wheel, turbine, and guide wheel form a closed circulation circle system, in which the working medium flows in an orderly manner, efficiently converts the mechanical energy of the engine and increases the output torque. The gearbox part is a multi-speed fixed-shaft structure, which can achieve smooth up and down gear operations through a clutch with wet friction plates without cutting off the power, greatly improving the convenience and consistency of engineering machinery operation. ​

At the Science and Technology Festival, Hangzhou Gear’s technicians enthusiastically introduced the product features and application scenarios to visitors in detail. They not only explained the basic performance parameters of the products, but also deeply analyzed the excellent performance of the products under various extreme working conditions. For example, in the harsh environment of mining, how can Hangchi’s transmissions rely on their rugged design and stable and reliable performance to ensure long-term and high-intensity operation of mechanical equipment. The atmosphere of on-site communication was warm and extraordinary, and visitors actively exchanged views with technicians on the development trend of transmission system technology. It is generally believed that with the continuous advancement of science and technology, the transmission system will develop in a more efficient, smarter and more environmentally friendly direction, and Hangchi has been at the forefront of the industry in these aspects. Its latest progress in gearbox research and development and manufacturing has provided new ideas and directions for the future development of the industry.

As a key high-tech enterprise of the National Torch Program, Hangzhou Gear has always been based on the main business of transmission devices since its establishment in 1960, and has continued to rely on scientific and technological progress to enhance its core competitiveness. Through continuous and high-starting point technological transformation, the company has introduced world-class high-precision equipment and established a complete quality management system and marketing service network. The wonderful appearance at the Science and Technology Festival not only reflects Hangzhou Gear’s important role in promoting technological progress in the industry, but also once again demonstrates the strong influence of its “Qianjin” brand. The “Qianjin” brand has long been recognized as a “well-known trademark in China”, and its marine gearbox has won the first batch of “Chinese famous brand products” in the industry. In the future, Hangzhou Gear will continue to uphold the corporate spirit of “loyalty, dedication, unity, and first”, seize opportunities, accelerate development, and make unremitting efforts to build a first-class Asian and internationally renowned transmission device enterprise group, and will also inject a steady stream of power into the technological innovation and development of the construction machinery industry. ​
