聯軸器偏差說明
1、彈性聯軸器可傳遞扭矩和回轉角度,同時吸收軸的安全偏差,當安裝偏差超過容許值時,可能會產生振動或導致聯軸器的壽命縮短,因此要確保偏差的調整適當。 2、軸的偏差有三種,分別是徑向偏差、角向偏差和軸向偏差。請調整偏差,使其低于各產品規格表中列出的容許值。 3、各產品所列之最大偏差容許值是指只有一種偏差存在的情況下,當兩種或更多種偏差同時存在時,容許值應低于各規格表中最大偏差的1/2。 4、偏差并不只有發生在設備裝配,工作過程中的振動、熱膨脹、軸承磨損等都會引起偏差。因此,建議將軸向偏差調整至低于最大值1/3。 Allgnment Adjustment 1,Flexible couplings transmit torque and rotational angle while absorbing misalignment.When the misalignment exceeds allowable values,vibration may result or the life of the coupling may become shortened.Make sure to adjust the alignment accordingly. 2,There are three types of shaft misalignment,namely in terms of parallel misalignment,angular misalignment and shaft end-play.Adjust the alignment to be below allowable values listed in the specification table of each product provided in this catalog. 3,The maximum misalignment listed in this catalog is the allowable value when only one of the misalignments exists.In case two or more misalignments exist at the same time,the allowable values will be less than 1/2 of the maximum misalignment listed in the specification tables. 4,Misalignments are sometimes caused not only by equipment assembly,but also by vibration,heat expansion,wear of bearings,ect.during operation.Therefore,it is recommended to adjust the shaft misalignment to be below 1/3 of maximum values. 軸與軸聯接過程出現的偏差說明 1 徑向偏差 parallel offset Misallgnment 安裝時,兩軸平行但中心不在同一直線上,這時產生的偏差稱為徑向偏差。 如左圖:
2 角向偏差 Symmetrical Angular Misalignment 安裝時,兩軸中心線互成一個角度,這時產生的偏差稱為角向偏差。 如左圖:
3 軸向偏差 End-play 由于機械原因產生的軸間往復微動的偏差稱為軸向偏差。 如左圖:
4 復合偏差 Combined Misalignment 由1、2、3產生的偏差組合稱為復合偏差。 |
