The invention discloses a hydraulic gear shifting main drive planetary speed reducer comprising a motor, a gear shifting system and a planetary speed reduction system. The gear shifting system comprises a gear shifting spline shaft. A gear shifting mechanism is connected to the gear shifting spline shaft in a sleeving manner. A gear shifting gear set is arranged on one side of the gear shifting mechanism. The gear shifting gear set is connected with the spline shaft in a coupling manner. One end of the spline shaft is connected with the gear shifting spline shaft through a bearing. The planetary speed reduction system comprises multiple stages of planetary speed reduction mechanisms. The hydraulic gear shifting main drive planetary speed reducer is reasonable in design and compact in structure, and the remote gear shifting operation is rapid, convenient, safe and reliable; by means of combined transmission of parallel stages, the gear shifting mechanism and the multiple stages of planetary speed reduction mechanisms, different torques are transmitted, and the application range of the device is widened; and reliability and efficiency of planetary speed reducer transmission are improved, and therefore the loading capacity, reliability and construction efficiency of a shield tunneling machine are greatly improved.
Description
technical field [0001] The invention relates to the field of shield machine reducers, in particular to a hydraulic shift main drive planetary reducer. Background technique [0002] The 21st century is the century of large-scale development of underground space. As an important construction equipment for underground engineering, the shield machine plays a pivotal role in the development of underground space. The domestic subway construction is in full swing, the international infrastructure is interconnected, and the potential of the world's shield machine market is being released rapidly. At present, the shield machine has become an indispensable special equipment for large-scale tunnel excavation, and has been widely used in tunnel projects such as subways, railways, highways, municipal pipe networks, river-crossing tunnels, and hydropower. [0003] As one of the core components of the shield machine, the main drive reducer of the cutter head is currently mainly imported i...
