Experimental research is very important for the in-depth understanding of new tooth profile, and is also a necessary link in the research system of new tooth profile. Through the accumulation of experimental data, the design system can be continuously improved, and the maturity of new tooth profile design technology can be improved. According to the currently published literature, some performance tests and verifications have been carried out during the development of the point-line meshing gear. Among them, Qian Zuoqin and others have used the mechanical power closed test bench to carry out the tests on the bearing capacity and vibration and noise performance of the point-line meshing gear with medium and hard tooth surfaces, and compared with the conventional involute gear transmission. The test results show that its contact strength is 1.5 times of that of the involute gear, The bending strength is 1.1 times that of the involute gear. Under the same working conditions, the air noise is 7 dB lower than that of the involute gear. The experimental research shows that the point-line meshing gear has the advantages of strong bearing capacity, low noise and high transmission efficiency compared with the involute gear.
Li Haixiang and others carried out the transmission performance and strength test on the point-line meshing gear. The performance test mainly includes the efficiency and noise test. In terms of efficiency, the point-line meshing gear is equivalent to the involute gear, and the noise is slightly better than the involute gear; The strength test includes tooth surface contact and tooth root bending test. Under the same working condition, the contact strength of the point-line meshing gear is 1.93 times of that of the involute gear, and the bending strength is 1.15 times of that of the involute gear. The test proves that the point-line meshing gear is a new type of gear transmission with high efficiency, low noise and high load capacity.
To sum up, at present, the domestic experimental research on point-line meshing gear is relatively small, mainly focusing on the research of transmission performance and load capacity, and the experimental research on the dynamic meshing characteristics of point-line meshing gear has not been carried out. The above related tests are mainly concentrated between 2000 and 2010, while the foreign experimental research on point-line meshing gear has not been found. In the follow-up research process, in order to fully demonstrate the transmission characteristics of the point-line meshing gear, it is necessary to strengthen the experimental research on the transmission performance, dynamic characteristics and reliability of the point-line meshing gear, so as to escort the application of this type of gear.
