充电式电钻静态堵转力矩测量分析与探讨

Analysis and Discussion on the Measurement of Static Locked-rotor Torque of Rechargeable Electric Drill

《手持式、可移式电动工具和园林工具的安全第2部分:电钻和冲击电钻的专用要求》是电动工具制造商参照并执行的国家推荐性安全标准之一。随着电动工具产品技术的不断更新,充电式电动工具占有的市场份额越来越多,对于充电式电钻的静态堵转力矩,尤其在力臂的界定等环节,业界的理解各不相同。通过对比三种实际应用方案,提出更有针对性的选择及参考依据。

Safety of motor-operated hand-held,transportable and garden tools-Part 2:Particular requirements for drills and impact drills is one of the national recommended safety standards that electric tool manufacturers refer to and implement.With the updating of the technology of electric tools,the market share of rechargeable electric tools is increasing.The industry has different understanding of the static locked-rotor torque of rechargeable electric drills,especially in the definition of the arm.By comparing the three practical application schemes,a more targeted selection and reference basis are proposed.
