The invention discloses a gear coupling. The gear coupling comprises a coupling male end, the coupling male end comprises a connecting rod, the connecting rod consists of a back half shaft and a front half shaft which are coaxially arranged by means of sleeving, and the back half shaft is fixedly connected with the front half shaft through cylindrical pins. The gear coupling has the advantages that the connecting rod consists of the back half shaft and the front half shaft which are connected with each other through three cylindrical pins in specific specification, so that normal torque transmission is ensured, and under the excessive load, the cylindrical pins break to cut off torque transmission to protect a power machine and a working machine. 本发明公开了齿式联轴器，包括联轴器公端，所述联轴器公端包括连接杆，连接杆包括套装在起的后半轴及前半轴，后半轴与前半轴同轴设置，后半轴与前半轴之间通过圆柱销固定连接。本发明采用技术方案具有以下技术效果：连接杆分为前半轴和后半轴两部分，前半轴和后半轴之间用三个特定规格的圆柱销连接，确保扭矩的正常传递，同时在过大载荷时，圆柱销断裂，切断扭矩传递，保护动力机与工作机。
