LT聯(lián)軸器的性能及特點(diǎn)

●彈性套柱銷聯(lián)軸器是利用一端套有彈性套（橡膠材料）的柱銷，裝在兩半聯(lián)軸器凸緣孔中，以實(shí)現(xiàn)兩半聯(lián)軸器的聯(lián)接。彈性套柱銷聯(lián)軸器曾經(jīng)是我國應(yīng)用泛的聯(lián)軸器，早在 20 世紀(jì) 50 年代末期即已制訂為機(jī)械部標(biāo)準(zhǔn)， JB08 — 60 彈性圈柱銷聯(lián)軸器，是我國個(gè)部標(biāo)準(zhǔn)聯(lián)軸器。

●彈性套柱銷聯(lián)軸器結(jié)構(gòu)比較簡(jiǎn)單，制造容易，不用潤(rùn)滑，不需要與金屬硫化粘結(jié)，更換彈性套方便，不用移動(dòng)半聯(lián)軸器，具有一定補(bǔ)償兩軸相對(duì)偏移和減振緩沖性能。彈性套工作是受壓縮變形，由于彈性套的厚度較薄，體積小，彈性變形有限，所以，彈性套柱銷聯(lián)軸器雖可補(bǔ)償軸線位移和彈性，但軸線位移許用補(bǔ)償量較少，彈性較弱。彈性套柱銷聯(lián)軸器是依靠柱銷組的鎖緊力而產(chǎn)生于接觸面的摩擦力矩，并壓縮橡膠彈性套來傳遞轉(zhuǎn)矩。適用于安裝底座剛性好、對(duì)中精度較高、沖擊載荷不大、對(duì)減振要求不高的中小功率軸系傳動(dòng)。

The performance and characteristics of the LT coupler

The elastic sleeve pin coupler is a pin with a flexible sleeve (rubber material) on one end, which is installed in the flange hole of the two-part coupler to realize the coupling of the two-and-a-half coupling. Column elastic sleeve pin coupling coupling was once the most widely used in our country, as early as the late 1950 s, which is for the mechanical standards, JB08-60 elastic dowel pin coupling, is China's first standard coupling.

Low column elastic sleeve pin coupling structure is simple, manufacture easily, no lubrication, don't need and metal sulfide, change the elastic sleeve is convenient, need not move half coupling, two axis relative offset compensation and vibration damping buffer performance. Elastic sleeve work is subject to compression deformation, due to the thickness of the elastic sleeve thin, small size, elastic deformation is limited, so, although column elastic sleeve pin coupling can compensate the axis displacement and elastic, but axis allowable displacement compensation quantity is less, less elastic. The elastic sleeve pin coupling is based on the locking force of the column pin group to produce friction torque on the contact surface, and compressible rubber elastic sleeve to transfer torque. It is suitable for small and medium power shafts with high rigidity, high accuracy, low impact load and low demａnd for vibration reduction.
