JS型蛇形彈簧聯(lián)軸器，是一種結(jié)構(gòu)先進(jìn)的金屬?gòu)椥?a target="_blank">聯(lián)軸器。它靠蛇形彈簧片來(lái)傳遞扭矩。其傳動(dòng)特性與優(yōu)點(diǎn)如下：
1、減振性好，使用壽命長(zhǎng)，聯(lián)軸器以蛇形彈簧片軸向嵌入兩半36％以上。梯形截面的蛇形彈簧片采用優(yōu)質(zhì)彈簧鋼，經(jīng)嚴(yán)格的熱處理，并特殊加工而成，具有良好的機(jī)械性能，從而使聯(lián)軸器的使用壽命遠(yuǎn)比非金屬?gòu)椥栽?a target="_blank">聯(lián)軸器（如彈性套 柱銷，尼龍棒銷聯(lián)軸器）大為增長(zhǎng)。
2、承受變動(dòng)載荷范圍大，起動(dòng)安全，兩個(gè)半聯(lián)軸器與簧片接觸的齒面是弧形的，當(dāng)傳遞扭矩增大時(shí)，彈簧片將沿齒弧面變形，使兩個(gè)半聯(lián)軸器作用在簧片上的力點(diǎn)靠近。簧片與齒面的接觸點(diǎn)即力矩的變化，是隨著傳遞扭矩的大小而變化的，它的傳動(dòng)特性是變剛度的。因而它具有比一般彈性聯(lián)軸器能承受更大的載荷變動(dòng)量。傳動(dòng)力使簧片沿齒弧變形時(shí)所產(chǎn)生的緩沖作用，尤其在機(jī)器起動(dòng)時(shí)或強(qiáng)力沖擊載荷時(shí)，于一定程度上有保護(hù)配套機(jī)件的安全性。
3、 傳動(dòng)效率高，運(yùn)行可靠，聯(lián)軸器的傳動(dòng)效率，經(jīng)測(cè)定達(dá)99.47％，其短時(shí)超載能力為額定扭矩的兩倍，運(yùn)行安全可靠。
4、 噪聲低，潤(rùn)滑好 鋁合金罩殼以保護(hù)彈簧避免運(yùn)轉(zhuǎn)時(shí)向外甩出，且殼體內(nèi)儲(chǔ)滿黃油，不僅使?jié)櫥己茫沂够善瑖Ш蠒r(shí)的噪聲被黃油阻尼吸收而消除。
5、 結(jié)構(gòu)簡(jiǎn)單，裝拆方便 整機(jī)零件少，體積小，重量輕，被設(shè)計(jì)成梯形截面的彈簧片與梯形齒槽的吻合尤為方便，緊密，從而使裝拆，維護(hù)比一般聯(lián)軸器簡(jiǎn)便。
6、 允許有較大的安裝偏差 由于彈簧片與齒弧面是點(diǎn)接觸的，所以使聯(lián)軸器能獲得較大的撓性。它能被安裝在同時(shí)有徑向，角向，軸向的偏差情況下正常工作。
The JS - type serpentine spring coupling is a kind of advanced metal elastic coupling. It delivers torque by a snake-shaped spring. Its transmission characteristics and advantages are as follows:
1. Good vibration resistance and long service life. The coupling is embedded more than two and a half 36 percent in the shaft of the snake-shaped spring. Trapezoidal cross-section of coil spring is made of high quality spring steel, the strict heat treatment, and special processing and become, has the good mechanical properties, which makes the service life of the coupling than non-metallic elastic element coupling (such as elastic dowel pin, nylon rods pin coupling) increase greatly.
2, large range of fluctuating load and under safe starting, two and a half coupling tooth surface is curved, in contact with the reed when the torque is increased, leaf spring deformation along the tooth surface, make two and a half point close to the coupling effect on the reed. The contact point of the reed and the tooth surface is the change of torque, which varies with the transmission torque, and its transmission property is variable stiffness. Therefore, it has more load variation than the general elastic coupling. The driving force makes the reeds have a cushioning effect during the deformation of the tooth arc, especially when the machine is starting or when the force impact load is strong, to some extent, the safety of the supporting equipment is protected.
3. High transmission efficiency and reliable operation, the transmission efficiency of the coupling is 99.47%, and its short-term overload capacity is twice as high as the rated torque, and the operation is safe and reliable.
4, low noise, good lubrication aluminum alloy cover to protect the spring to avoid running when thrown outwards, and casing filled with butter, not only make good lubrication, and make the reed meshing noise is butter damping absorption and elimination.
5, simple structure, convenient installation the machine parts, small volume, light weight, is designed to be trapezoidal section leaf spring with trapezoidal alveolar is particularly convenient, close together, so that the installation, maintenance easy coupling than normal.
6. It is permissible to have a larger installation bias because the spring and tooth arc are touched, so that the coupling can get a greater flexibility. It can be installed at the same time with radial, angular, axial deviation and normal work.
