扭力限制器又名扭矩限制器、力矩限制器、BMOOM限制器等，其價格便宜、結構簡單、方便拆裝維護、過載后反應速度快、設定扭矩精確度高、使用壽命更長，配一個微型開關過載后能輸出電信號以方便報警或自動停掉電機。扭力聯軸器廣泛應用于(yu)電(dian)子裝備行(xing)業(ye)、自動(dong)化生產線(xian)、輸(shu)送機(ji)行(xing)業(ye)等。

扭矩聯軸器是聯接主動機與工作機的一種部件，主要功能為過載保護，力矩聯軸器是當超載(zai)或(huo)機械故障(zhang)而(er)導(dao)致所需扭矩超過設定值時，它以打(da)滑(hua)形式限(xian)制傳動(dong)系統(tong)所傳動(dong)的(de)扭力，打(da)滑(hua)的(de)同時也能一個信(xin)號輸出停掉(diao)電機和減速(su)機，當過載(zai)情形消失后自(zi)行恢復(fu)聯結。

扭矩安全聯軸器螺帽或螺栓調整彈簧力，預設其滑動扭矩。按工作原理可分為摩擦式扭矩限制器和鋼球式扭矩限制器(滾珠式扭矩限制器)，安全離合器應(ying)用范圍(wei):電(dian)子裝備行業、自動化生產線、輸送機(ji)行業等。

柱(zhu)銷聯軸(zhou)器(qi)是利用一端套(tao)有彈(dan)性套(tao)（橡膠材料）的柱(zhu)銷，裝在兩半聯軸(zhou)器(qi)凸緣孔(kong)中，以實現兩半聯軸(zhou)器(qi)的聯接。

彈性(xing)柱(zhu)銷(xiao)聯軸器是一種結(jie)構簡(jian)單制(zhi)造容易，無需潤滑(hua)，裝拆彈性(xing)柱(zhu)銷(xiao)便(bian)捷的傳動(dong)基礎(chu)件，利用(yong)兩個帶法蘭(lan)孔的半(ban)聯和(he)置于(yu)起重的非金屬彈性(xing)柱(zhu)銷(xiao)來(lai)傳遞扭矩，適用(yong)于(yu)中(zhong)低速和(he)中(zhong)低扭矩場合(he)。

彈(dan)性(xing)柱(zhu)銷(xiao)齒(chi)(chi)式聯(lian)軸器采用(yong)非金(jin)屬(shu)彈(dan)性(xing)柱(zhu)銷(xiao)和兩個(ge)(ge)帶(dai)齒(chi)(chi)形半(ban)聯(lian)以及一個(ge)(ge)外圈(quan)的(de)齒(chi)(chi)形套環設計，利用(yong)非金(jin)屬(shu)彈(dan)性(xing)的(de)變形來傳遞扭矩同時緩沖減震(zhen)，補償角(jiao)向(xiang)位(wei)移(yi)。

彈性套(tao)柱(zhu)銷聯(lian)軸(zhou)器設計簡(jian)單巧妙，適用性較(jiao)廣的(de)聯(lian)軸(zhou)器，利用帶彈性套(tao)的(de)柱(zhu)銷聯(lian)接兩個帶銷孔的(de)半聯(lian)，實現扭矩傳遞的(de)同(tong)時兼(jian)具較(jiao)大的(de)角向(xiang)補償，同(tong)時減震緩沖性能(neng)良好，可以用在速度較(jiao)快(kuai)的(de)場(chang)合(he)，無(wu)需(xu)潤滑，銷套(tao)更換便(bian)捷。

The pin gear coupling is designed with non-metallic flexible pin, two toothed semi-couplings and a toothed sleeve ring with an outer ring. It uses non-metallic flexible deformation to transfer torque and cushion shock and compensate angular displacement. The flexible pin coupling is a basic transmission parts that has simple structure, needs no lubrication, and is easy to manufacture, install and disassemble the flexible pin. It uses two semi-couplings with flange holes and a non-metallic flexible pin for crane to transmit torque, suitable for low-to-medium speed and low-to-medium torque occasions. The design of the elastic sleeve pin coupling is simple and clever in design and has wide applicability. It uses the pin with elastic sleeve to connect two semi-couplings with pin holes to realize torque transmission and larger angular compensation. At the same time, Pin and bush couplings has good shock absorption and buffering performance, which can be used in high-speed occasions without lubrication and requiring easy pin sleeve replacement.
