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電子裝(zhuang)備行業、自(zi)動化(hua)生產線、輸送機行業等。

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(dang)超載(zai)(zai)或機(ji)(ji)械(xie)故(gu)障而導致所需扭矩超過(guo)設定值(zhi)時，它以打滑(hua)形式(shi)限制傳動系統(tong)所傳動的扭力(li)，打滑(hua)的同時也能一個信號輸出停掉電機(ji)(ji)和減速機(ji)(ji)，當(dang)過(guo)載(zai)(zai)情形消失后自行(xing)恢復聯結。

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)，安全離合器應用范圍:電子裝備行(xing)(xing)業(ye)、自(zi)動(dong)化生產線、輸送(song)機行(xing)(xing)業(ye)等。

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.
