Abstract

The invention relates to a diaphragm disc coupling for connecting a BPRT speed changing clutch, and relates to the technical field of mechanical transmission. The diaphragm disc coupling aims to solvethe problems that the axial size of an existing diaphragm disc coupling is large, the mass is large, consequently the unit dynamic balance precision is low, and the unit operation stability is affected. The diaphragm disc coupling comprises an input flange, an intermediate shaft, an output flange and two diaphragm discs, the shape of the intermediate shaft is a hollow shell with openings in the two ends, the two ends of the intermediate shaft are each provided with one diaphragm disc, the diaphragm discs and the intermediate shaft are positioned through a plurality of positioning pins, the middle portions of the outer side ends of the diaphragm discs are provided with positioning plates, the end surfaces of the outer sides of the positioning plates are uniformly provided with a pluralityof connecting bolts in the circumferential direction, the tail ends of the connecting bolts penetrate through the diaphragm discs, the connecting bolts rotate on the end face of the intermediate shaft, and flange plates of the input flange and the output flange are fixedly connected to the outer circumference of the outer side end of one diaphragm disc through the multiple connecting bolts. The diaphragm disc coupling is used for connecting the BPRT speed changing clutch.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a diaphragm coupling for connecting a BPRT transmission clutch. Background technique [0002] The BPRT unit is a complete set of blast furnace blast energy recovery unit driven by the gas turbine and the motor coaxially. By installing the BPRT unit, it can not only recover the pressure energy and heat energy of the blast furnace top gas, reduce the flow noise of the gas transmission pipeline network, but also Highly intelligent control of blast furnace top pressure, axial fans, and gas turbines improves the smelting intensity and output of blast furnaces. The variable speed clutch is the core equipment in the BPRT unit, and it is connected with the gas turbine and the blower through a coupling. The traditional unit adopts diaphragm coupling, which has the advantages of low manufacturing cost and reliable operation. With the continuous improvement of the power an...
