這里說的45#鋼指聯軸器材質，膜片為304不銹鋼，316不銹鋼等等。 膜片聯軸器遠銷國外贏得認可。其常見型號規格有JM型，JMJ型，另一種說法是JM單膜片型，JMJ雙膜片型等。每個地區對其認識叫法不同。

初步選定的膜片聯軸器聯接尺寸，即軸孔直徑d和軸孔長度L，應符合主、從動端軸徑的要求，否則還要根據軸徑d調整聯軸器的規格。 主、從動端軸徑不相同是普通現象，當轉矩、轉速相同，主、從動端軸徑不相同時，應按大軸徑選擇聯軸器型號。新設計的傳動系統中， 應選擇符合GBT3852中規定的七種軸孔型式，推薦采用J1型軸孔型式，以提高通用性和互換性，軸孔長度按膜片聯軸器產品標準的規定對于膜片聯軸器性能及應用這里就不過多贅述了，對于很多廠家幫助選型中，大部分選用膜片聯軸器也是因為如此： 膜片聯軸器采用很薄的金屬膜片作為彈性元件，角向和軸向剛度低，因而附加軸向力和附加彎矩很小。由于齒式聯軸器齒面可相對滑移，所以人們往往覺得齒式聯軸器能夠補償 大的角向和軸向不對中，而不會給機組附加影響。事實上，這種想法是錯誤的。 彈性膜片聯軸器在受載后由于摩擦和兩軸的不對中會對軸和軸承產生很大的附加軸向力和附加彎矩。
45 # steel elastic diaphragm coupling model specifications
Here refers to the coupling of 45 # steel material, diaphragm for 304 stainless steel,316 stainless steel and so on.
Diaphragm coupling exported to win recognition abroad. The common specifications areJM, JMJ, is another way of saying that JM single diaphragm type, JMJ doubleDiaphragm type, etc. Each region different understanding of the term.

Preliminary selected diaphragm coupling dimensions, namely the axle hole diameter d andlength of the shaft hole, L should conform to the requirements of the main, driven enddiameter of axle, otherwiseAlso according to the diameter of axle d adjustment of the specifications of thecoupling.
Master and slave side different diameter of axle is a normal phenomenon, when the sametorque and rotational speed, the main, driven end diameter of axle is not same, shouldchoose by large diameter of axle
Choose the coupling model. The new design of transmission system, should choose toconform to that stipulated in the GBT3852 seven shaft hole type, J1 is recommended forthe typeShaft hole pattern, in order to improve the versatility and interchangeability, therules of the shaft hole length by diaphragm coupling product standardPerformance and the application for diaphragm coupling here but many here,For many manufacturers to help in the selection, most choose diaphragm coupling is alsobecause of this:
Diaphragm coupling with thin metal film as the elastic element, angular and axialstiffness is low, additional axial force and the additional bending moment isconsequentlySmall. Relative slip due to the coupling tooth surface can be, so people tend to thinkof coupling can compensate large angular and axial don'tFor them, and not give additional effects unit. In fact, this idea is wrong.
Flexible diaphragm coupling after loading wrong because of friction and two axis willbe much on the shaft and bearing additional axial force and the additional bendingmoment.
