The influence of the lateral vibration of the planetary gear on the gear portion of the reducer, between the input shaft and the center wheel, and between the carrier and the output shaft, uses a gear coupling. The use of these measures on the planetary reducer not only greatly increases the load carrying capacity of the reducer, but also extends the service life of the reducer. The circular tooth shape is used to further increase the bearing capacity of the single tooth of the gear.
Using the arc-toothed frequency converter test, on the one hand, the number of teeth of the gear can be reduced to a minimum (6-8 teeth) to increase the modulus of the gear and further improve the single-tooth bearing capacity; on the other hand, due to the arc gear The tooth profile is inclined in the axial direction, so that the meshing coefficient of the gear can be increased, the bearing capacity of each pair of meshing teeth can be increased, and the axial force on the center double gear shaft can be eliminated. The special load sharing mechanism is adopted, which can eliminate the uneven distribution of load between the planetary gears, and eliminate the uneven distribution of the load along the axial direction of each of the planet gears participating in the meshing.
In order to reduce the turbine section and the drill section. The overall structural characteristics of the turbo-rigs with planetary reducers developed and produced by the All-Russian Institute of Drilling Technology in Russia are analyzed, and the internal structure of the planetary reducers and the load-carrying capacity of the reducers are carefully analyzed. Effective measures.
Shantui Construction Machinery Co., Ltd., founded in 1980, was a national category I key enterprise integrating research & development, production and sales of main engine products and key components of earth moving machinery, pavement construction & compaction machinery, building machinery, hoisting machinery and other construction machinery series products; and it is also a state-owned joint-stock listed company. It is one of the top 50 manufacturers of construction machinery in the world, and one of China`s top 500 manufacturers. On January 1, 1997, [Shantui" listed on the Shenzhen Stock Exchange (stock code: 000680). In June 2009, Shandong Heavy Industry Group was established, and Shantui became one of its Subsidiaries. As the backbone of construction machinery industry in China, Shantui always ranks as No.1 in the industry.
