Φ177mm PQF連軋管機組脫管機聯(lián)軸器系統(tǒng)改進

Modification of Coupling System of Extrac tor of Φ177 mm PQF Pipe Mill

摘要: 分析了Φ177mm PQF連軋管機組脫管機連桿聯(lián)軸器系統(tǒng)存在的3種設(shè)計缺陷，并據(jù)此提出改進措施：將原鼓形齒等結(jié)構(gòu)取消，將連接軸與內(nèi)齒套設(shè)計成一個整體結(jié)構(gòu)，將外齒軸與齒接手設(shè)計成一個整體的外齒套，取消聯(lián)軸器內(nèi)部的連接螺栓，改用通孔螺栓將兩個整體結(jié)構(gòu)連接在一起，從而提升了聯(lián)軸器的整體強度，提高了聯(lián)軸器的使用壽命。

Abstract: Analyzed in the paper are the three shortcomings of the extractor link rod coupling system of the Φ177mm PQF pipemill as originated from the design thereof.Accordingly，countermeasures as follows are proposed. Taking out the existing drum gear structure；getting the connecting axel and inner gear bush integrated into one structure，and getting the external gear axel and the gear coupling integrated into a one-piece type external gear bush；replacing the connecting bolt within the coupling with a through-hole bolt which links the above said two entirety structures.As a result，the strength of the coupling as a whole is increased，and so is the service span of it.
