However, in this case the suspension element comprises two sets of elastic arms 28 spaced in the axial direction to improve the guiding function of the magnet assemblies 5, 6, 7 relative to the motor coil assembly 34. 9 shows the magnet assembly disassembled from the suspension element, although only the electrode piece 6 is visible. The suspension element is also shown partially disassembled to the right side for clarity.
서스펜션요소나 조립체는 캐리어(9), 커플링부재(12) 및 탄성아암세트(28)을 성형할 단일 플라스틱재도 포함한다. 커플링부재(12)는 하기에서 더욱 상세히 기술한 상하부품으로 구성된다.The suspension element or assembly also includes a single plastic material to form the carrier 9, the coupling member 12 and the elastic arm set 28. Coupling member 12 is composed of the upper and lower parts described in more detail below.
이 점에 근거하여, 서스펜션요소는 코일형성기(4)의 단부를 수용 및 위치시킬 환형홈(18)을 가진 환형캐리어(9)를 포함한다. 연결바아(35) 배열은 캐리어로부터 외향연장되며 이들의 외측단부는 탄성부재(2) (도면에 없음)에 대해 지지되는 피트(36)에 연결된다. 피트(36)은 하부 탄성아암(28)세트의 외측단부(29)를 지지한다.Based on this, the suspension element comprises an annular carrier 9 having an annular groove 18 for receiving and positioning the end of the coil former 4. The arrangement of the connection bars 35 extends outwardly from the carrier and their outer ends are connected to the pit 36 supported against the elastic member 2 (not shown). The pit 36 supports the outer ends 29 of the set of lower elastic arms 28.
하부 탄성아암세트의 내측단부(30)는 도 1 및 2에서 보는 바와 같은 일반형 마그네트조립체의 전극편(6)의 플랜지(8)하단을 수용 및 지지할 수 있도록 정확히 구성된 직립형 플랜지(37)를 갖춘 하부 환형커플링부재(12)를 수용한다.The inner end 30 of the lower elastic arm set has an upright flange 37 that is correctly configured to receive and support the lower end of the flange 8 of the electrode piece 6 of the general magnet assembly as shown in FIGS. 1 and 2. The lower annular coupling member 12 is accommodated.
피트(36)는 전극편(6)의 플랜지(8)를 둘러싸는 형태로된 상부 환형커플링부재(12)를 수용할 상부 탄성아암세트(28)로 구성된 상부 서스펜션부재를 지지할 상향연장 포스트(38)를 받쳐준다. 상부 서스펜션부재는 받침포스트의 상단이 아암세트(28)의 외측단부를 수용하고, 한편 아암의 내측단부는 상부 환형커플링부재를 수용하는 형태로 배치된다. 상부 환형커플링부재는 사고로 결합이 해제되는 위험을 막기위해 스냅작용으로 전극편(6)을 연결하는 고정자(도면에 없음)도 포함할 수 있다. 이와 별도로, 전극편과 서스펜션은 접착수단으로 함께 고정시킬 수 있다.The pit 36 is an upwardly extending post for supporting an upper suspension member composed of an upper elastic arm set 28 for receiving an upper annular coupling member 12 in a form surrounding the flange 8 of the electrode piece 6. Support (38). The upper suspension member is arranged such that the upper end of the support post receives the outer end of the arm set 28, while the inner end of the arm receives the upper annular coupling member. The upper annular coupling member may also include a stator (not shown) that connects the electrode pieces 6 in a snap action to prevent the risk of accidental release of the coupling. Separately, the electrode piece and the suspension can be fixed together by means of adhesion.
본 발명은 플라스틱 성형 혹은 공동성형 등으로 제조한 일체형 서스펜션 조립체를 포함하여 관성진동 여자기를 제조하는 편리한 방법을 제공한다.The present invention provides a convenient method of manufacturing an inertial vibration exciter including an integral suspension assembly made by plastic molding or cavity molding.
