Siemens Energy is located in southern China Nuozhadu - Guangdong and Xiluodu - Guangdong HVDC project two key components. Nuozhadu - Guangdong HVDC project is ± 800 kV transmission voltage, transmission capacity of 5,000 megawatts; Xiluodu - Guangdong HVDC project is ± 500 kV transmission voltage, transmission capacity of 6400 MW gear maintenance, These two projects will be built for the metropolitan area of ??Guangdong to provide electricity. The main disadvantage is that they spur gear vibration occurs. Whether it is due to the design, manufacture or deformation, etc., at the same time along the entire tooth surface may occur some changes involute shape. This will lead to a regular, once per tooth incentive imported reducer repair, it is often very strong. The resulting vibration caused both large load on the gear, and cause noise. Another negative point is that the contact time, and sometimes additional strength by two pairs of meshing obtained and can not be used, because the stress is circulating in the situation of a single tooth meshing defined. flender gear maintenance, repair gear, Sichuan, identify Zhunsipurui provided by Jinan Electrical Equipment Co., Springfield.
