Big modulus gear should not be used Hardened Hardened Hardened scraping scraping technology used widely in foreign countries, mainly for small-modulus, high-volume, high productivity, and economic characteristics, general modulus of 2.5 a 3.5 between, more used in automobile manufacturing. Big modulus gear shaving machine tool because it is difficult with such a high stiffness to ensure precision gear, so hard skiving process for selection should be cautious.

The bearings can be used in the housing structure to improve gear eccentric exposure eccentric structure, foreign-made equipment used more often, can be used to improve the meshing gears (the backlash, the contact spot), but the manufacturing complex. Can also be used at the individual bearings plus eccentric way to eliminate processing errors cabinet, to ensure good contact, because of the large volume of the box, once the holes of error exceeded, it is difficult to repair, using the method can also be eccentric as a remedy Measures C3.

Do load test run load test link is essential, and should be carried out under working conditions as close as possible, and should ensure adequate time to observe vibration, noise, bearing temperature rise and other technical indicators. If you live with the condition, we should try to load test. A better approach is to use the hydraulic load dynamometer. Load should progressively be, if conditions permit, do short-term overload test. There are several ways to load, can be determined according to the situation. In short, the load test can effectively test the gear contact strength, glued and wear and so much closer to the real work, the more reliable test results.
