Description
Technical field
The utility model belongs to coal gas axial flow fan technical field, is specifically related to a kind of coal gas axial flow fan disc couplin that can block motor leakage current.
Background technique
Can coal gas axial flow fan plays a very important role in iron and steel is produced, because guarantee the manufacturing efficiency that it is long-term, stable operation is being related to iron and steel enterprise.In actual production process, coal gas axial flow fan interruption of service happens occasionally, and has had a strong impact on safety in production and the environment protection standard work of Iron And Steel Plant.Wherein, because the unreasonable accident causing of coupling pattern is also occupied certain ratio.According to the needs of the Environmental Conditions of coal gas axial flow fan and fed sheet of a media, except coal gas axial flow fan self being had to requirement of explosion proof, to coupling, need to have requirement of explosion proof equally, the leakage current that must completely cut off motor imports blower fan into by coupling, to prevent electrical spark; Secondly, according to each smelting stage of converter, as preparation, preheating/fall cover, blow, re-blow, tap, clear up fire door, add the difference that steel scrap is converted the iron stage, the operating conditions frequent changes of blower fan, also needs to make coupling can meet requirement low in 30～38min, at a high speed frequent speed governing operation; The 3rd, convenient, install, overhaul, reduce maintenance technique and require and maintenance cost aspect, the user of iron and steel enterprise has also proposed requirement to coupling.
The coupling that in currently available technology, coal gas axial flow fan is used does not all possess the function that simultaneously meets above-mentioned three requirements.As the notification number patent " insulating coupling " that is CN201714853U, it is at the connection part installing insulating dish of coupling, installing insulating sleeve pipe in the bolt through-hole of coupling, be assemblied in the bolt in spaghetti and be all equipped with insulation spacer with the nut that bolt matches, this patent is not obviously handed over connection part and is referred to what position, dismounting trouble; And its elastic strength is low, can not meet requirement low, at a high speed frequent speed governing operation.
Summary of the invention
For coupling of the prior art, can not adapt to requirement low, at a high speed frequent speed governing operation, the problems such as dismounting trouble, maintenance cost height, invented a kind of good insulating, explosion-proof, be applicable to low, at a high speed frequent speed governing operation, it is convenient to dismantle, overhaul, a kind of coal gas axial flow fan disc couplin that can block motor leakage current with low cost.
Above-mentioned goal of the invention is achieved through the following technical solutions: a kind of coal gas axial flow fan disc couplin that can block motor leakage current, the disc couplin that its main points are to be contained on motor output shaft, coal gas axial flow fan axle comprises the drive end half-coupling being contained on motor output shaft, be contained in the transfer panel on drive end half-coupling, be contained in the cast aluminium gear ring on transfer panel, be contained in the driven end half-coupling on coal gas axial flow fan axle, be contained in the elasticity assembly parts on driven end half-coupling; Described cast aluminium gear ring is shaped with double wedge or the recessed tooth that points to the cast aluminium gear ring center of circle, and by being shaped with the recessed tooth that coordinates with double wedge or the recessed tooth of cast aluminium gear ring or the elastic caoutchouc gear ring of double wedge and the wheel hub of steel, the two is composited described elasticity assembly parts.
As preferably, described cast aluminium gear ring is shaped with 24～36 double wedges or the recessed tooth that points to the cast aluminium gear ring center of circle, and elastic caoutchouc gear ring is corresponding 24～36 recessed teeth or the double wedge coordinating with 24～36 double wedges of cast aluminium gear ring or recessed tooth that be shaped with also.
The beneficial effects of the utility model are: be contained in the disc couplin on motor output shaft, coal gas axial flow fan axle, because the elastic caoutchouc gear ring above it has non-conductive, so its leakage current that can completely cut off motor imports blower fan body into by motor output shaft, coal gas axial flow fan axle and produces electrical spark, and disc couplin can make motor output shaft, the mutual transmission of coal gas axial flow fan axle; In addition, elastic caoutchouc gear ring has high strength elastic, so can adapt to the frequent starting of high-power coal gas axial flow fan, frequent speed governing; Again because be reserved with larger axial distance between motor output shaft, coal gas axial flow fan axle, so dismounting and that disc couplin, maintenance, replacing standby redundancy etc. are installed is all very convenient, this also effectively reduces the maintenance cost of coal gas axial flow fan.
