NTB高度定制的消隙螺母

Kerk NTB Highly Customizable Anti-Backlash Nut and Lead Screw

Kerk®NTB系列消隙螺桿組件可承受比ZBX或KHD系列組件更高的負載。它采用專利收緊機構,可在整個使用壽命期間提供較高的軸向剛度,同時將系統的阻力矩保持在最小值。NTB系列螺母組件消除了對螺母預加載荷以補償負載的需要。該螺母采用自潤滑聚縮醛制造而成,可在軋制的精密梯形螺桿上高效運行。Kerkite®復合聚合物也可作為標準配置。螺桿由303不銹鋼制成,可選配我們專有的長壽命Kerkote®TFE涂層。NTB簡單緊湊的設計易于針對特定應用進行更改。NTB組件在整個負載和速度范圍內都有低阻力矩、高系統剛度、平穩性和長使用壽命等優點。

  • 潤滑選項 +


    Haydon Kerk Motion Solutions™提供多種潤滑選擇。所有Kerk®螺桿螺母都包含自潤滑聚合物。在高要求應用中,Kerkote®和Black Ice™ TFE涂層可提供優異的性能。 

    Kerkote® TFE涂層 

    Kerkote TFE是一種軟涂層和長期干性潤滑劑,適用于較軟的塑料,如有/無機械加固的乙縮醛和尼龍。通過螺母從涂層上拾取Kerkote TFE顆粒以及塑料螺母內部潤滑劑的遷移,實現對螺母/螺桿接口的潤滑。潤滑劑雖是固體,但在流體潤滑劑中也具有一定的“擴散”能力。Kerkote TFE涂層螺桿有最高水平的自潤滑性能,不應在可能出現油或其他潤滑劑污染的環境中進行潤滑或使用。 

    Black Ice™ TFE涂層 


    Black Ice TFE涂層具有許多Kerkote TFE涂層的優點,與之不同的是,它是一種硬涂層,在大多數環境中都有卓越的耐用性,幾乎可用于所有類型的聚合物絲桿螺母。Black Ice TFE不是干性潤滑劑,而是一種抗摩擦涂層,它可完全屏蔽被涂敷的金屬表面特性。雖然它不適用于金屬或玻璃纖維增強螺母,但Black Ice TFE可牢固地粘合到螺桿表面,并且能夠承受來自污染、剛性系統摩擦、流體沖擊和沖洗應用的磨損。

  • 設計和工程數據 +


    螺桿精度
    Haydon Kerk Motion Solutions, Inc采用獨特的精密軋制工藝來制造螺桿。Kerk螺桿的標準導程精度為0.0006英寸/英寸(mm/mm)。導程精度可達0.0001英寸/英寸(mm/mm)。如需更高的導程精度,請咨詢廠家。組件具有50微英寸(1.25微米)的極高重復定位精度。
     
    端部加工
    Haydon Kerk Motion Solutions可根據要求為您定制設計螺桿,以便您自己加工。  

    臨界速度
    這是螺桿可能經受振動或其他動態問題的旋轉速度。請參閱臨界速度表以確定應用參數是否會導致速度接近臨界值。減少臨界速度問題的方法有:使用更長的導程、選擇更大的直徑或增加軸承座的支撐力度。

    Critical Speed

    長度
    最長有12英尺(4米)的長度,(具體取決于直徑和導程)。對于可定尺寸的螺桿,其長度以6英寸遞增(6英寸、12英寸、18英寸……)+1.0英寸/-0英寸

    導程
    每轉的行程。所有螺桿均按導程而非螺距排列。導程 = 螺距 x 線數

    螺距
    波峰到波峰的距離或一除以每英寸的螺紋數。(在一個多線螺紋中,螺距等于導程除以線數。)

    移動速度
    我們使用的螺母材料在各種條件下都有很長的耐磨壽命。但是,高負載和或高速度會加快螺母的磨損。這些情況可能需要特殊的材料。我們針對連續工作的直線移動速度給出了以下建議,以實現最佳的使用壽命:
    導程 移動速度 導程 移動速度
    1/10 - 1/2英寸 4-英寸/秒 1 - 12 mm 100毫米/秒
    1/2 - 1英寸 10-英寸/秒 12 - 25 mm 250毫米/秒
    1 - 2 1/2英寸 30-英寸/秒 25 - 60 mm 760毫米/秒

    最大負載
    盡管Kerk®消隙組件能夠承受相對較高的載荷,且不會發生嚴重故障,但這些單元被設計為應在尺寸圖中所示的載荷下運行。

    效率
    效率是工作投入與工作產出的關系。它不應該與機械優勢混淆。列出的效率是基于Kerkote®TFE涂層螺桿的理論值。

    轉矩
    螺桿組件所需的電機轉矩由三個部分構成:慣性轉矩、阻力矩和移動負載的轉矩。請注意
    這是單獨驅動螺桿組件所需的轉矩。還必須考慮與驅動摩擦軸承和電機軸、運動部件以及由于組件錯位而導致的與阻力相關的其他轉矩。

    慣性轉矩:

    T = I α  其中I = 螺桿慣性
     j                   α = 角加速度

    阻力矩:
    Kerk消隙組件通常具有1到7盎司英寸的阻力矩。阻力矩的大小取決于標準出廠設置或客戶指定的設置。一般來說,預設力越高,消隙特性就越好。

    移動轉矩

    T=        負載 x 導程
      L    2 π x 效率

    反向移動:
    有時也稱為可逆性,反向移動是指螺桿通過施加在螺母上的推力負載轉動的能力。一般情況下,當螺桿導程小于無涂層螺桿直徑的1/3或Kerkote®TFE涂層螺釘直徑的1/4時,不會發生反向移動。對于可能出現反向移動的較高導程,保持負載所需的扭矩為:

    T =         負載 x 導程 x 反向移動的效率     
     b                                   2π

    螺桿直線度:
    測得的螺桿直線度為總指示偏差(TIR)。螺桿的標準直線度為0.003英寸/英尺。Haydon Kerk Motion Solutions可根據客戶要求提供更高的規格。  

    在發貨前,所有螺桿都經手工較直。

    除Kerk®標準螺母類型外,定制的產品也占公司產品的很大一部分。修改可能是簡單的變化,例如不同的安裝孔形狀或安裝螺紋、微小的尺寸變化或特殊材料。Haydon Kerk Motion Solutions生產的梯形螺母具有巨大的價值。通過使用定制模具和特殊加工,螺母還可以用于導軌襯套、滑架、同步皮帶輪、齒輪、注射器組件、傳感器支架、編碼器、夾具和許多其他附加元件。此外,定制設計的螺母可以提供快拆安裝座、部分螺紋嚙合、半螺母結構或特殊形狀??商峁┨厥獠牧弦蕴岣呓M件的性能。材料可以根據極端溫度、化學相容性、熱處理、機構規定、特殊載荷和許多其他特定要求進行選擇。
