彈性柱銷聯軸器的特點
●本聯軸器已列為國家標準GB5014-85，適用于各種機械聯接兩同軸線的傳動軸，通常用于動頻繁的高低速運動。工作溫度為-20 ～+80℃；傳遞公稱扭矩為40～20000N.m。
●彈性柱銷聯軸器具有較大結構簡單、合理，維修方便、兩面對稱可互換，壽命長，允許較大的軸向竄動，具有緩沖、減震、耐磨等性能。
●軸孔型式有圓柱形(Y)、圓錐形(Z)和短圓柱形(J)。軸孔和鍵槽按國家標準GB3852-83《聯軸器軸柱和鍵槽形式及尺寸》的規定加工。半聯軸器采用精密鑄造，鑄鐵HT20-40、鑄鋼ZG35Ⅱ，軸孔和鍵槽采用拉制成型，柱銷采用MC尼龍b制成。
●彈性柱銷聯軸器是利用若干非金屬彈性材料制成的柱銷，置于兩半聯軸器凸緣孔中，通過柱銷實現兩半聯軸器聯接，該聯軸器結構簡單，容易制造，裝拆更換彈性元件比較方便，不用移動兩半聯軸器。彈性元件（柱銷）的材料一般選用尼龍，有微量補償兩軸線偏移能力，彈性件工作時受剪切，工作可靠性極差，僅適用于要求很低的中速傳動軸系，不適用于工作可靠性要求較高的工況。
The characteristics of the elastic pin coupling
The coupling has been listed as the national standard gb5014-85, which is suitable for the transmission shaft of two coaxial lines of mechanical connection, usually used for high and low speed movement. Working temperature is 20 ~ + 80 ℃; The transfer torque is 40 ~ 20000n. m.
Low elastic dowel pin shaft coupling with bigger has simple and reasonable structure, convenient maintenance, bilateral symmetry, interchangeable, long life, allows larger axial channeling, buffer, shock absorption, wear-resisting performance, etc.
The axial hole type has cylindrical (Y), conical (Z) and short cylindrical (J). The shaft hole and keyway are machined according to the national standard gb3852-83 "coupling shaft and keyway form and dimension". Half coupling with precision casting, cast iron HT20-40, cast steel ZG35 Ⅱ, axle hole and the keyway USES the drawing forming, dowel pin with MC nylon made from b.
Low elastic dowel pin shaft coupling is the use of a number of non-metallic elastic material dowel pin, put in two and a half coupling flange hole, achieved by column pin half coupling, the coupling structure is simple, easy to manufacture, replace the elastic element installation is more convenient, need not move two half couplings. Elastic element (dowel pin) nylon material selection in general, there are two axis offset trace compensation ability, flexible work under shear, work reliability is poor and is only applicable to medium speed transmission shafting with low requirements, the operation condition of the high reliability requirement does not apply to work.
