For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of centre revolving joint for shield machine, and it includes center steering joint mounting flange, rear axle, the gyroaxis being sequentially connected with；The revolution body being sheathed on described gyroaxis；The diaphragm rings being sheathed on described rear axle and be fixedly connected by anti-pivoted frame with described revolution body, is also associated with the bolster that cutterhead can be made to work in an inclined state between described diaphragm rings and described rear axle.
Optimizing, described diaphragm rings is set in described rear axle by being opened in perforate thereon, described bolster be fixed on the perforate of described diaphragm rings in and be sheathed on the buffer gasket on described rear axle.
Optimize, described bolster is expansion joint, described expansion joint includes the front outer shroud being fixedly connected with described diaphragm rings and being sheathed on described rear axle, it is fixed on inside described front outer shroud and is pressed in the seal stopper ring on described rear axle, it is sheathed on described rear axle and rear ring outside one end that described rear axle is connected with described gyroaxis, it is fixed between described rear ring and described front outer shroud and is sheathed on the telescopic on described rear axle, connect the sealing gasket in the rear between ring and described rear axle, inside described telescopic with described rear axle outside formed oiling space, the grease for buffering it is filled with in oiling space.
Further, described rear ring offers for the oil filler point of oiling in oiling space.
Further, between described rear ring and described rear axle, it is provided with assemblage gap, in described assemblage gap and be positioned at described sealing gasket both sides and be provided with additional encryption seal ring.
Further, the volume side that described front outer shroud is relative with described rear axle is provided with two annular mounting groove, is respectively equipped with two seal stopper rings in two described annular mounting groove, and the seal stopper ring internal diameter being positioned at front end is little compared with the internal diameter of the seal stopper ring being positioned at rear end.
Further, the outside of described rear axle and be positioned at described seal stopper ring and be provided with stepped front inner ring relative to position, two described seal stopper rings are pressed on an end face periphery of described front inner ring respectively.
Owing to technique scheme is used, the utility model compared with prior art has the advantage that the utility model sets up bolster between diaphragm rings and rear axle, ensure that cutterhead, in run-off the straight, does not interferes with diaphragm rings when causing rear axle to tilt, and can normally work.
