New gear online measuring machine available

The 3501 gear fast online measuring machine jointly developed by Beijing University of Technology and Haliang Group was recently launched. It is said that this is the first online measuring instrument for gears that has been independently developed to achieve practical level.
According to Shi Zhaoyao, a professor at Beijing University of Technology who participated in the research, gear quality is one of the key factors affecting the performance of the whole machine. Therefore, 100% of the finished gears should be measured according to the quality standards of the US vehicle gear industry. According to reports, almost all vehicle gear manufacturers in the United States are equipped with fast online measuring machines. With the rapid development of China's automobile and other host industries, the output value of China's gear industry in 2005 was close to 60 billion yuan. In order to improve product quality and production efficiency, it is urgent to solve the problem of on-site inspection of high-volume finished gears.
However, the on-site detection of gears must take into account various factors such as speed, environment and precision, which is a very difficult technical problem. The 3501 gear fast on-line measuring machine adopts the multi-dimensional measurement principle of gear double-sided meshing. While maintaining the advantages of traditional double-bit measurement, it can quickly obtain the tooth-to-ear error information of the gear, which not only solves the requirement of tooth-to-tooth measurement during rapid measurement of gear production site. It also opened a new direction for the traditional double-bit measurement technology. The instrument not only measures 8 items more than the traditional gear online measuring machine, but also measures a gear for 4 seconds and the measuring speed reaches the international level.
