Recently, the “2024 Mechanical Industry Transmission Industry Integration and Innovation Forum” hosted by the China Machinery Industry Enterprise Management Association was successfully held in Hangzhou. At this innovation forum, more than 200 experts and representatives at the meeting focused on in-depth discussions on digital empowerment, intellectual property rights, operating costs, and industrial chain collaboration in the industrial transmission industry, and formed advocacy to promote the high-quality development of the mechanical industry transmission industry.
Returning to the field of planetary reducers, this industry forum undoubtedly clearly pointed out the development direction for domestic planetary gear reducer companies, namely: focusing on the high-quality development of planetary gear reducers.
The famous Japanese entrepreneur Kazuo Inamori once said: “If you want your product to be liked by consumers, firstly, you must be satisfied with it.” The importance of product quality is even more evident.
In the field of planetary reducers, there is a “dark horse” enterprise – Shanghai SGR Heavy Industry Machinery Co.,Ltd. which has been paying close attention to the quality of its planetary gear reducer series products and focusing on the technological innovation of planetary gear reducers for many years, and is highly recognized by customers in the industry.
How does SGR ensure the quality of worm gear reducers?
(1) About SGR
Shanghai SGR Heavy Industry Machinery Co.,Ltd. is a Shanghai high-tech enterprise and has been selected into the list of Shanghai’s “specialized, sophisticated, unique and innovative” enterprises. Many of its planetary gear reducers and worm gear reducer series products have been recognized as high-tech achievement transformation projects.
SGR aims at the development direction of gear transmission devices along the lines of compactness, modularization, standardization, low vibration, and low noise. After more than 10 years of intensive cultivation, SGR group has formed a research and development team mainly composed of doctoral students and senior engineers, and has developed planetary gear reducers, toroidal worm gear pair optimization design system, four-axis linkage complex surface CNC grinder, toroidal worm and hob measuring instrument (the first in China), etc.
（2）SGR’s high-load turntable
SGR is rock-solid in its original commitment to technology and has never stopped its pace of product iteration and technological innovation. It has released its new product-the high-load turntable.
The high-load turntable of SGR adopts a plane double enveloping toroidal worm pair, which has a load capacity 2-3 times greater than that of a double-lead cylindrical worm pair of the same specification, a transmission efficiency 5%-10% higher, and has the following obvious advantages.
a.The macro contact area and micro meshing performance of the worm pair are designed through parameter optimization and modified based on the working conditions.
b.The worm is precisely ground by a four-axis linkage machine and tested by a special measuring instrument. The main technical indicators are higher than the 6th grade accuracy requirements in GB/T16445-1996.
c.The worm gear is formed by rolling or milling, with high tooth surface finish and no running-in is required.
d.The contact spots of the worm pair are excellent, and the transmission efficiency of the whole machine is higher than the requirements of GB/T16444-2008.
e.The center distance of the turntable is 100-800, the table diameter is 200-1300, the transmission ratio is 10-120, and the side clearance of the worm gear pair is 1 minute.
（3）SGR’s commitment to gear products
“A slight error can lead to a huge mistake.” Shanghai SGR Heavy Industry Machinery Co.,Ltd. is well aware that the product precision of planetary gear reducers is of vital importance. The planetary gear reducer company is equipped with the first toroidal worm measuring instrument in China, as well as three-coordinate measuring instruments, microhardness testers, reducer power performance test benches and other experimental equipment to meet the technical testing and service needs of planetary gear reducer products and ensure product quality.
As early as 2009, SGR won the “First Prize for Scientific and Technological Progress in the Gear Industry in 2009” evaluated by the China Gear Industry Association, was recognized as a “Shanghai High-tech Achievement Transformation Project”, and obtained an invention patent.
It is foreseeable that in the future, Shanghai SGR Heavy Industry Machinery Co.,Ltd. will surely promote the high-quality development of the mechanical industrial transmission industry by relying on its product strength of “high quality + hard technology”.
