Door closer gear shaft and machining method thereof
The invention relates to the technical field of gear shafts, in particular to a door closer gear shaft. The door closer gear shaft comprises a gear shaft body, the gear shaft body is integrally formed and comprises a shaft tooth part, a cylindrical part and connecting parts, the shaft tooth part is arranged in the middle of the gear shaft body, the connecting parts are arranged at the two ends of the gear shaft body, and the cylindrical part is arranged between the shaft tooth part and the connecting parts; and the outer diameter of the shaft tooth part is larger than that of the cylindrical part, the outer diameter of the cylindrical part is larger than that of the connecting parts, eight connecting teeth which are annularly arranged are evenly arranged on the periphery of each connecting part, a tooth groove is formed between every two adjacent connecting teeth, and a connecting threaded hole is formed in the end of each connecting part. According to the door closer gear shaft, the structural design is reasonable, the meshing area of the connecting portion of the gear shaft body and a rocker arm can be effectively increased, the attaching effect is good, damage is not likely to happen, the twisting effect between the rocker arm and the gear shaft body can be enhanced, and the service life of a product can be prolonged.
本发明涉及齿轴技术领域，具体涉及一种闭门器齿轴，包括齿轴本体，所述齿轴本体一体成型，其包括轴齿部、圆柱部和连接部，齿轴本体的中部设有所述轴齿部，齿轴本体的两端均设有所述连接部，所述轴齿部与连接部之间设有所述圆柱部，所述轴齿部的外径大于所述圆柱部的外径，所述圆柱部的外径大于所述连接部的外径，所述连接部的外周均匀地设有八个呈环形排列的连接齿，相邻连接齿之间形成齿槽，连接部的端部设有连接螺纹孔。本发明提供一种闭门器齿轴，结构设计合理，能有效增加齿轴本体与摇臂连接部位的咬合面积，贴合效果好不易损坏，不仅能增强摇臂与齿轴本体之间的扭动效果，还有利于延长产品的使用寿命。
