The full-scale worm gear oil evaluation test bench established by Zhengzhou Machinery Research Institute tests the mechanical efficiency, gluing load capacity and temperature rise of lubricating oil of worm gear oil. This test bench is for the performance test of worm gear oil. Effective means. However, the establishment of a full-scale worm gear oil evaluation test bench, the investment is large and the construction period is long, it is difficult to synchronize with the oil product development. Moreover, the evaluation cost of the worm gear oil rig is high, and the test time is long. From the installation of the worm gear to the end of the test, the cumulative test time is more than 200 hours. Therefore, in the actual work, the HQ-1 friction and wear test machine is used to simulate the worm gear oil platform evaluation test, which not only satisfies the needs of scientific research, accelerates the research progress, and saves the test cost.
Test equipment and materials, test equipment HQ-1 friction and wear tester has a variety of contact forms of friction pairs, its relative sliding speed, test load, test temperature adjustment range is wide, friction and its record display is sensitive, easy to operate, It can meet the test requirements for simulating the evaluation of worm gear oil. In the worm gear transmission, the worm is made of alloy steel or carbon steel, and the worm wheel copper is used as the ring gear. According to the requirements of the test machine for the shape of the test piece and the requirements for the material of the worm gear, the specifications of the self-made test piece.
From the sliding friction pair composed of the HQ-1 test machine test piece, it can be known that the HQ-1 friction and wear tester can simulate the lubricity, extreme pressure wear resistance and temperature rise of the worm gear oil, that is, record with friction The instrument records the friction force, calculates the friction coefficient, and determines the lubricity and extreme pressure wear resistance of the oil by the magnitude of the friction coefficient. According to the relative sliding speed and load carrying capacity of the worm gear, the worm gear oil of different viscosity grades can be selected, and the L-CKE320 worm gear oil is used in the worm gear transmission with a relative sliding speed of 3.5 to 10 m/s.
