Abstract

The invention discloses a double-drive planetary transmission driving system of a shield machine. The system follows a driving law of double-input, the conflux output of input planet carriers, the diversion of an output planetary system I and an output planetary system II and the conflux to a twin ring gear, has the double-input and single-output characteristics, achieves the purpose of increasing torque and widening speed adjustable range, realizes the low speed high torque output by changing an output torque and a rotating speed, changes the driving means of a motor, can obtain many different output working conditions and can be suitable for many types of shield machines. The asynchronous problem existing in a structure of multipath speed changes and a plurality of power input utilized by a traditional driving system is fundamentally solved. A sealed planet wheel train load is commonly shared by two output planetary systems and twin gear rings and the function of power diversion and conflux is realized, thereby the bearing capacity is increased. The system has larger transmission ratio, can adapt to the high powerful output and can bear heavier construction load.

Description

technical field

[0001] The invention relates to a shield machine drive assembly, in particular to a shield machine double-drive planetary variable speed transmission system. Background technique

[0002] The shield machine is a special construction machine for the construction of the shield method. Because the shield construction has the advantages of high mechanization, fast construction speed, quality assurance, high safety, wide practicability, less impact on ground buildings and environmental protection, etc., it has been It is widely used in large-scale projects such as subways, highways, railways, gas transmission, water transmission, municipal administration, and hydropower tunnels.

[0003] Since shield machines are mostly used in more complex working environments, the requirements for the drive and transmission system of shield machines are relatively high, requiring them to be able to adapt to harsh working environments, to withstand heavy loads and high impacts, a...
