Uqhagamshelo lwerabha oludityanisiweyo oludityanisiweyo, olukwabizwa ngokuba yimeko yomoya ithumbu elibhetyebhetye, luhlobo lwamalungu erabha abhetyebhetye, yeyezihlanganisi ezibhetyebhetye zemibhobho yentsimbi.Uqhagamshelo oludityanisiweyo lwerabha oludityanisiweyo ludityaniswe ngumaleko werabha wangaphakathi, umaleko wokuphucula amalaphu ethaya le-chinlon kunye nomaleko werabha wangaphandle, emva koko ngokubumba i-vulcanization kwaye idibanise ne-screw thread.
Amalungu okwandiswa kwerabha yoqhagamshelo olunemisonto asetyenziselwa ukufunxa ukungcangcazela kunye neentshukumo zobushushu kwiinkqubo zemibhobho.Banikezela ngokubambisana okuguquguqukayo okunceda ukunciphisa uxinzelelo kwizixhobo ezixhunyiwe ngelixa zinciphisa ingxolo kunye nokulahlekelwa kwengcinezelo.Izinto zerubha zivumela ukuba zivumelane nokungahambi kakuhle, ukuchithwa kwe-angular, ukunyanzeliswa kwe-axial kunye nokwandiswa, i-lateral offset kunye ne-torsional movement.

Iinzuzo zokusebenzisa i-rubber ene-threaded joints expansion joints zibandakanya: ukuphuculwa kwenkqubo yokusebenza, ukunyuka kokuguquguquka kwentshukumo kunye nokulawulwa kwe-vibration, ukunciphisa uxinzelelo lokunciphisa, ukuthembeka kwenkqubo ephuculweyo, ukuphucuka kweempawu zokuhamba, kunye nokuxhathisa ukubola.
