汽車離合器分離軸承及其單元
 
  FYB—汽車離合器分離軸承及單元,為汽車的重要零部件,其主要功能是通過軸承軸向移動,實現汽車發動機與傳動系統之間的結合或斷開,從而使汽車平穩起步、 換擋、停車,并對汽車傳動系統超載起保護作用。該類軸承具有自潤滑、低振動、離合平穩、使用壽命長等特點,為汽車離合器分離軸承最佳選擇。

△結構形式
  軸承具有內、外圈選轉,自動調心,軸承單元可推式、可拉式軸向位移,帶座與不帶座等多種結構供顧客選擇。

△產品精度

  尺寸公差和幾何精度按GB/T307。
  配套鋼球精度等級20級(國標GB/T308)。

△材料

  滾動體材料為GCr15軸承鋼,淬硬HRC60—65。
  內外圈材料為GCr15軸承鋼,淬硬HRC61—65。
  沖壓零件材料為優質低碳鋼。

△特殊說明
  裝配容易,軸向間隙可調整,需充分考慮使用中的軸向載荷。
  如對軸承噪聲、轉動力矩等有特殊要求需協商確定。

△標準
  GB/T5312—2001汽車離合器分離軸承及其單元(JB-12)
Auto Clutch Release Bearing and Its Unit

FYB---auto clutch release bearing and its unit are the important parts of autos. Its main function is to make axial movement with the aid of bearing so as to realize connection and release between auto motor and driving system, and as the result autos can smoothly start, shift gears and stop. Therefore it has a protection function for overload on auto driving system. This kind of bearings is characterized by self-lubrication, low vibration, smooth release and long service life. It is the best choice among auto clutch release bearings.

Types of Designs:
There are a lot of designs available for customers to choose, such as rotation type of inner & outer races, automatic adjusting center, pushing/drawing-type axial displacement of bearing unit, and structures with or without brackets.

Product Precision Accuracy:
Dimensional tolerance and geometrical accuracy is based on GB/T307.
Matched steel ball accuracy is grade 20 (ISO GB/T308).

Materials:
Material for rolling body is GCr15 bearing steel, quench-hardening HRC60---65.
Material for inner and outer races is GCr15 bearing steel, quench-hardening HRC61---65.
Material for punched parts is quality low-carbon steel.

Special Directions:
Easy to mount, axial clearance adjustable, axial load during operation is fully considered.
Special requirements for bearing noise, rotating moment and etc are to be defined through negotiation.
