Abstract

회전자 또는 구동축과 플렉시블 샤프트와의 죠인트부를 콤팩트하게 해서 이송시의 저항을 저감시키고, 종래의 금속제 플렉시블 샤프트에 비교해서 길이를 단축시키며, 내약품성에 우수하고, 제조 비용도 낮출 수 있는 일축 편심 나사 펌프를 제공한다.A joint portion between the rotor or the drive shaft and the flexible shaft is made compact so as to reduce the resistance at the time of transportation and shorten the length compared with the conventional metal flexible shaft, Pump.

일축 편심 나사 펌프(100)의 회전자(10)의 일단부(펌프 케이스(8)측)에는, 보스(10a)가 일체로 형성되고, 플렉시블 샤프트(9)의 일단부가 보스(10a) 내에 삽입되어, 접착제에 의하여 회전자(10)과 일체로 접속되고 있다. 이 플렉시블 샤프트(9)가, 엔지니어 플라스틱의 하나인 PEEK(폴리에테르에테르케톤)에 의하여 원주형태로 압출된 봉형부재로 형성되고 있다.A boss 10a is integrally formed at one end (the pump case 8 side) of the rotor 10 of the uniaxial eccentric screw pump 100 and one end of the flexible shaft 9 is inserted into the boss 10a And is integrally connected to the rotor 10 by an adhesive. The flexible shaft 9 is formed of a rod-like member extruded into a cylindrical shape by PEEK (polyetheretherketone), which is one of engineer plastics.
