The workers of Linyi Wanhua Chemical Equipment Manufacturing Co., Ltd. are currently debugging the fulcrum spiral bevel gear reducer, which will be sent to Shandong Kangqiao Biotechnology Co., Ltd. This new type reducer overcomes the shortcomings of conventional spiral bevel gear reducers and has the characteristics of large load capacity and no oil leakage.

Spiral bevel gear reducer is the first choice for high-power, but its defects such as easy oil leakage, large noise, bulky size, and difficult maintenance have not been effectively improved. Based on the characteristics of the current reducer, Wanhua Company has carried out the research and development of a new generation of spiral bevel reducer with the help of the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences. After repeated trials and experience accumulation, it has successfully developed a fulcrum type spiral bevel gear reducer.

According to Li Guangyou, general manager of Wanhua, the main gear of the reducer adopts Gleason''s quasi-hyperbolic tooth type, which is the first in China to have a large wheelbase bevel gear, which realizes the multi-bearing installation of this part, and the lever arm is slower than the traditional spiral cone. The machine is increased by more than 30%, and the fulcrum surface design further improves the centripetal force of the spiral tooth rotation. Under the rated power, the fulcrum type spiral bevel gear reducer has the largest output budget among similar reducers in China. In addition, Wanhua replaced the blind holes with the conventional spiral bevel gear bearing through holes and adopted a separate box design. At the same time, the sealing device adopts the TC fluorine rubber seal of FREUDENBERG, Germany, so that the output shaft will not leak oil for life.
