近日有专家对我们提到,杭州一家公司通过冷镦(也可称为冷精锻)技术,将人形机器人丝杠的运行寿命提升 到了真正可用级别,成本公摊也有望降到可用范围。 目前,人形 机器人有两个 部位主要 用 到 丝杠 ,分别是 腿部线性执行器 和 灵巧手 ,前者多采用 反向行 星滚柱丝杠, 后者则多 用微型滚珠丝杠, 两者 精度要求 都 不 算 低, 在原先,市场上大多 灵巧手用的微 型滚珠丝杠, 多是由磨床制造,设备要求较高, 精密加工和装配的要求也高 ,大多企业单位生产时间达数 十分钟,能保证余量、精度、效率都能满足的企业少之又少,大多最终生产的丝杠产品运行 寿命普遍就 仅 20 万次 ,对于落地而言成本过高,因为这意味着如果人形 机器人每天在工厂干 12 小时,每分钟抓放 10 次工件,一天 约拉升约 7200 次, 20 万次 最晚 1 个月 就会报废更换 。 反向行星滚珠丝杠运行架构是螺母带丝杠运行,因此设计上难度在于需要紧凑适配机器人关节、制造公差小、 可传大载荷扭矩,而且球轴承随着磨损精度衰减问题较为明显,动态响应滞后,加之加工慢、产量低,行星滚 柱丝杠的精度等级从 P0 到 P7 , P0 最高,人形机器人大多得需 ...
