The technical scheme that the utility model adopts to solve its technical problem is: a kind of miniature shield machine is with main driving input gear supporting structure, comprise for receiving the planetary reducer of electric motor acting to provide main driving source of torque, and the sun gear axle center being arranged at this planetary reducer for passing to the input gear of the gear ring of main driving by the moment of torsion of described planetary reducer, this input gear forms cantilever end away from one end of described step-down gear, the cantilever end of described input gear is provided with a semi-open type cantilever support, this semi-open type cantilever support one end is sheathed on the cantilever end of described input gear by socle girder pedestal bearing, this semi-open type cantilever support the other end is fixed on the casing of described planetary reducer.
As further improvement of the utility model, described semi-open type cantilever support has the scallop, semi-cylindrical portion and the semi-annular half that are in turn connected to form one, wherein the position, center of this scallop is sheathed on the cantilever end of described input gear, and the tail end of this semi-annular half is fixed on the casing of described planetary reducer.
As further improvement of the utility model, described scallop is formed centrally circular arc, and it is provided with installation circular hole.
As further improvement of the utility model, between the semi-cylindrical portion of described semi-open type cantilever support and the casing of described planetary reducer, it is provided with semi-open type supporting.
As further improvement of the utility model, described socle girder pedestal bearing and described input gear and semi-open type socle girder are respectively equipped with shaft end ring between supporting.
The beneficial effects of the utility model are: this miniature shield machine with main driving input gear supporting structure by arranging semi-open type cantilever support on the pedestal bearing of input gear, be equivalent to double supporting structure, have take install space little, the processing of this part is simple, and body structure is simple with processing, safeguards that maintenance is simple, reliable transmission height, improve the engagement carrying condition of gear, it is beneficial to the advantages such as work-ing life of improving main driving, is specially adapted to be installed on the main driving of miniature shield machine of limited space.
