選擇方法:

  1. 從負荷條件或機器之設計強度,決定所需之滑動扭力。如機器之負荷條件不詳,則將扭力限制器之滑動扭力設定為其安裝軸相關馬達所產生扭力之1.5~2倍
  2. 請選擇扭力範圍和內徑範圍足夠的扭力限制器。
  3. 由設於摩擦板間的中心構件厚度,決定正確的軸襯長度。軸襯之撰擇不可大於中心構件的寬度,中心構件之最大厚度見表中之『S〈最大〉』欄。   

中心構件:

  1. 中心構件之摩擦面必須研磨加工以得額定之扭力,共成為平坦,平行,與內徑相垂直,不含任何灰塵,鏽皮或油污,表面研磨度以3S~6S(63微吋加工)為宜。
  2. 如中心構件不符合本規範,則滑動扭力不穩定。中心構件內徑之加工尺寸見下表。可用最少鏈輪齒數和軸襯長度之撰擇見下表。

SELECTION

  1. Dtermine the required slip torque from the loading conditions or from the design strength of the machine.If the loading conditions of the machine are unknown,setthe required slip torque of the Torque Limiter to 1.5 to 2 timesthe torque that the motor produces on theshaft where the Torque Limiter is mounted.
  2. Select a Torque Limiter which has enough torque range and bore range.
  3. Determine the proper bushing length from the thickness of the center member to be inserted between the friction facings.Always choose the largest bushing which does not exceed the width of the center member. Maximum thickness of the center member is shown as "S max,"in the dimension table.

CENTER MEMBER

  1. The center member should be machined on its rubbing sur face to obtain the rated torque and be flat and parallel,and free from rust, scale and oil, Surface finish recom mended is 3S to 6S (63 micro-inches finish).if the center member is not in accordance with these speci fications, the slip torque will be erratic
  2. Bore of the center member to be machined is shown in the rable beloe. Also, minirmum number of sprocket teeth to be used and bush ing length to be chosen are listed in the table below.
