谐波减速器 Harmonic Drive
工业机器人关节里实现高减速比、高精度、零回程间隙的核心精密零件，机器人产业链的隐形冠军环节。
别名： Harmonic Drive／ 谐波减速器／ 谐波
是什么
谐波减速器 是工业机器人和人形机器人的关节里的精密齿轮组件，能在很小的体积内实现 1:30 到 1:320 的减速比，同时保证：
- 高精度定位（角度误差 <1 弧分）
- 零回程间隙（关节反转无空转）
- 高扭矩密度
一台人形机器人通常有 20-40 个关节，每个关节都需要一颗谐波减速器或类似精密减速器。
全球供应格局
历史上由日本 Harmonic Drive Systems 垄断（绿的谐波这个译名就来自他们的中国名）。中国厂商绿的谐波（A 股 688017）正在快速追赶，国产替代叙事强烈。
| 公司 | 国家 | 地位 |
|---|---|---|
| Harmonic Drive Systems | 日本 | 创始厂，全球老大 |
| 绿的谐波 | 中国 | 国产替代代表 |
| 来福谐波 | 中国 | 新进玩家 |
为什么是机器人产业链关键
每台特斯拉 Optimus、Figure、Boston Dynamics 人形机器人量产 → 谐波减速器需求线性放大。而这环节产能极难快速扩张（精密齿轮加工 + 长达数月的良率爬坡），所以一旦量产开启会是结构性短缺。
Serenity 的视角
这是让”白毛股神”名号在中文社区出圈的标志性案例。2026 年 6 月他点名 绿的谐波 后，该股一路走高成为市场焦点，东方财富等中文媒体专题报道，“白毛股神”称号广泛传播。
他原话：
“I do like Harmonic Drive (6324) as the Western Lead, but I’d rather use my capital to support Western supply chains.”
中文社区进一步解读为他对中国国产化的机器人减速器供应链给出战略性认可。
他的二阶推论：
- $VPG Vishay Precision Group：特斯拉 Optimus 的应变片 (strain gauge) 供应商，“BOM 占比极高的隐形冠军”
- 关联 $TSLA Optimus 量产时间表

优必选IPO或提振机器人板块，哈默纳科长期受益于人形机器人规模化。
@Yangyftz 在我看来，这似乎是正常的市场波动。我认为优必选(Unitree)的成功IPO可能会在短期内提振整个机器人板块。无论如何，从长期来看，我认为哈默纳科(Harmonic Drive)将受益于人形机器人规模化至百万台级别，从而实现创纪录的营收。
英文原文
@Yangyftz Looks like normal market volatility to me. I think a successful IPO from Unitree might bring up the robotics sector as a whole near-term. Regardless, I see Harmonic Drive long-term to have record revenue numbers coming from humanoid ramp as robots scale up to the millions.

看好宇树和Agility，重仓后者，并持有哈默纳科。
对于机器人公司，我对宇树科技(Unitree)和Agility Robotics这两家人形机器人玩家持看好态度。我在Agility Robotics上的持仓集中度最高，因为我个人更偏好美国的人形机器人玩家。在上游组件敞口方面，我目前持有：- 哈默纳科(Harmonic Drive) https://t.co/YbMdym2gCQ
英文原文
For robotics companies, I have a favorable view on Unitree and Agility Robotics, two humanoid players. And I have largest concentration in Agility Robotics, since I personally prefer US humanoid players. For upstream component exposure, I currently own: - Harmonic Drive https://t.co/YbMdym2gCQ

博主复盘持仓：核心主题盈利丰厚，但CPO及韩国股短期亏损，强调中期视角。
我想强调的一点是，并非我所有的观点都是盈利的，尤其是在短期时间框架内！ 我的核心三大主题是：新云（能源）、存储和光子学。 我很高兴我从每个细分领域选择了字面意义上的顶级表现者，从 $NBIS 到 $EWY，再到 $SIVE。 然而，由于一份关于共封装光学(CPO)延迟的虚假分析师报告（$NVDA 已驳斥），我仍然承受着相当大的亏损： 这摧毁了我3个台湾CPO多头头寸，包括 Foci、Msscorp、Xintec 等（目前大幅亏损）。不过，Shunsin 和 Win Semi 的表现要好得多。 我之前提到的一些日本公司，如 Towa、Harmonic Drive、NCI 等，在短期波动后表现要好得多。 至于韩国，是的，我对 Auros 和现在的 Foosung 都有创伤后应激障碍(PTSD)，两者都亏损（我并没有持有 093370，只是看着价格走势感到 PTSD）。 我不知道是否还会再碰韩国，波动性太大了。但我仍然认为，随着 SK 海力士/三星的资格认证 + 大规模量产(HVM) 以及未来日本供应链的关闭，这些最终会转为盈利。 我也改变了一些之前的多头观点，比如 $XLU，因为伊朗战争将降息预期从3-4次降至0次，这并没有很好地兑现。我之前提到的三家软件公司 $TTD、$META 最终都亏损了。对于 $SNAP，我在注意到其无尽的基于股票的薪酬(SBC)会计方法后也改变了论点。$RDDT 的观点在很长一段时间内终于从 $130 涨到 $170 转为盈利。 但我想，我绝大多数的观点，如 $MRVL、$NBIS、$ARM、$INTC、$MU、$LITE、SK 海力士、三星（针对大盘股）。 一直到 $AXTI、$LITE、$AAOI、$RPI、$IQE 等（针对小盘股）的方向性表现都相当不错。 像 $SIMO、$HPS.A、$TSEM、$AEHR、$LPK、$SOI、$ALRIB 等随机标的也都表现尚可。 由于我大多数的多头观点今年至今(YTD)都是三位数的收益，混合平均收益可以说是压倒性的绿色（盈利）。 但我确实错过了一些。 入场点也很重要……我提到 $AAOI 在 $30 或 $AXTI 在 ~$13 时，但并非每个人都有相同的入场点。所以如果有人在 $220 买入 AOI 然后跌到 $160，我会感到抱歉。 但无论如何，我更倾向于在几个月的中期时间框架内，而不是几周的时间框架内，来评判观点的兑现情况。
英文原文
I think something to highlight also is not all my ideas are green, especially on short term timeframes! My core three themes are Neoclouds (Energy), Memory, and Photonics. And I'm glad I chose the literal top performers for each segment from $NBIS to $EWY leaps to $SIVE. However, I still have pretty large losses following the false analyst report on CPO delays that $NVDA refuted: That nuked 3 of my TW CPO longs from Foci, Msscorp, Xintec and others. (which are heavily red). Shunsin / Win Semi are holding up much better though. Some of the other ones in Japan that I've mentioned like Towa, Harmonic Drive, NCI, etc. are performing much better following short-term volatility. As for Korea yes I have PTSD for from Auros and now Foosung that are both both red (I didn't own 093370 though, just got PTSD watching price action). Idk if I'll touch Korea again, just way too volatile. But I still think those will end up green eventually following Sk hynix/samsung qualifications + HVM, and the future japanese supply chain shutdown. I also did change some of my previous long ideas like $XLU following the Iran War nuking all chances of rate cuts from 3-4 down to 0, and that didn't play out too well. Three software names I mentioned previously like $TTD , $META ended up red. $SNAP , I also changed my thesis after noticing the endless SBC accounting methods. $RDDT idea was finally in the green from $130 -> $170 after a long time. But I think the vast majority of my ideas like $MRVL , $NBIS , $ARM , $INTC , $MU , $LITE , SK Hynix, Samsung, for larger cap. Down to $AXTI , $LITE , $AAOI , $RPI, $IQE, and others for smaller cap positions directionally play out pretty well. With random stuff like $SIMO , $HPS.A, $TSEM , $AEHR , $LPK, $SOI, $ALRIB, and so on all ended up turning out aight too. The blended average is kinda overwhelmingly green since majority of my long ideas are triple digit YTD. But I've definitely missed a few. Also entry point is really important too... I mentioned $AAOI at $30 or $AXTI at ~$13, but not everyone has the same entry point. So if someone bought AOI at $220 and it dropped to $160, I'd feel bad. But regardless, I'd prefer to judge how ideas play out on medium term timeframes over a few months rather than a few weeks.

我确实认为绿的谐波(688017)是中国机器人行业里突出的零部件龙头。 我研究过很多其他机器人标的和 $TSLA Optimus 供应商，但绿的谐波非常独特。 和那些做低利润率组装、低价值零部件、或更容易被设计替换的公司相比，它不一样。 高盛研究等西方机构多次提到绿的谐波： -> 它是一家具有高技术壁垒的公司，例如谐波减速器。 -> 并且很可能在每台人形机器人里捕获高价值零部件成本，比如行星滚柱丝杠。 简单说，绿的谐波覆盖了： 1. 多种不同零部件，且进入壁垒高 2. 如果把这些部件合在一起，占每台人形机器人较高的物料清单(BOM)价值 3. 低成本大规模量产能力 这些都对应每一台被制造出来的人形机器人。 请在做决定前自己研究这个主题；但从长期看，如果你相信人形机器人行业会增长，我认为绿的谐波(688017)非常有吸引力。 主要风险来自其他新兴中国公司在不同单项零部件上抢占市场份额。 另一个风险是量产后利润率随时间下降，就像 $VPG 的传感器从早期预生产阶段的750美元降到150美元。 但总体而言，我不认为中国以外的公司，比如 Harmonic Drive(6324)，能在大规模生产上实现同样成本。这也是为什么 $TSLA Optimus 正在中国建立广泛供应链。 所以我们很可能看到供应链分化：一边是来自中国供应链、成本约1.5万到2万美元的低成本量产人形机器人；另一边是来自西方供应链、成本更高的人形机器人。 如果你只看当前市盈率并说它很高，我认为很大一部分误解来自没有看未来增长。 目前还没有真正大规模量产。智元机器人(AGIbot)最近在3月实现了1万台产量。 但未来3-5年，如果按照埃隆·马斯克和其他人的预测，每年会生产数百万台人形机器人，那么人形/机器人行业的总可寻址市场(TAM)会非常大。 所以我的预期是，回头看绿的谐波当前106.5亿美元市值，相对于它在整体机器人市场里可能捕获的份额，会显得非常小。 因此我不认为这样的投资论点应该用短期时间框架来衡量，也不认为人们应该主动交易这类名字。 它更像是一个长期投资想法：这家公司可能在未来几年指数级增长的整体人形机器人市场中，捕获相当重要的一部分。
英文原文
I do think LeaderDrive (688017) is China's standout component leader in the robotics sector. I've done a lot of research on other robotics picks / $TSLA Optimus suppliers, but LeaderDrive is extremely unique. Compared to others doing lower margin assembly, or lower value components, with higher design out risk. Western institutions like Goldman Sachs Research flags LeaderDrive many times: -> As a company with high technology barriers (eg. harmonic reduction gear). -> and likely capturing high component value costs like planetary roller screws of each humanoid produced. In simpler terms with LeaderDrive, you cover: 1. Many different components, with high barrier to entry 2. High BOM of each humanoid made, if you combine them together 3. Mass production capability at low cost. For each humanoid made. Please do your research on this topic before making your own decision; but long-term if you believe in humanoid sector growth: I think LeaderDrive (688017) is very compelling. Risk is mainly coming from other emerging Chinese companies taking over market share of different individual components. As well as mass-production margins decreasing over time; as seen with $VPG going from $750 (for early stage pre-production) -> $150 for sensors. But in general, I don't believe companies outside China like Harmonic Drive (6324) can achieve the same costs for mass production, which is why $TSLA Optimus is creating extensive supply chains from China. So we'll likely see supply chains be bifurcated with cheap mass production $15k-20K humanoids from Chinese supply chains. And higher cost humanoids from Western supply chains. Again if you look at current P/E ratios and say it's high; a lot of it is misunderstanding comes from not looking at forward growth: Nothing has been mass produced yet. AGIbot has recently achieved 10k units produced back in March. But in the next 3-5 years, the TAM of the humanoid/robotics sector forecasted by Elon Musk and others very large, if he's expecting millions of humanoids to be produced a year. So my expectation is the current $10.65B MC would look very tiny in hindsight of LeaderDrive's market capture of the overall robotics market. So I don't believe thesis like this should be measured in short term timeframes (or that people should actively trade names like these). Moreso a long term investment idea about how this company could capture a material part of the overall humanoid market that exponentially grows over the next few years.

Sivers通过Aeva成为Boston Dynamics的激光供应商，CPO技术是物理AI开发核心
有趣的事实：同一家公司经常出现在不同的供应链中。一个可能的例子是：$SIVE 作为上游激光供应商，通过以下路径供应给 Boston Dynamics：Sivers -> $AEVA FMCW（CW DFB 激光器）-> LG Innotek -> Boston Dynamics。我个人最初其实是因为4D AI而看好Aeva的。偶然发现Sivers是他们4D FMCW激光雷达的高置信度激光供应商。所以你实际上可以在光子学领域获得机器人曝光，而用于超大规模数据中心AI的同款CW激光器也在使用。虽然近期收入增长可能是$SIVE通过Aeva为$NVDA自动驾驶汽车相关架构供应激光器批量增长。人形机器人可能要到2028年？你总能得到更多间接曝光，比如MU的内存或$INTC的边缘CPU，但当然也有更直接的曝光方式。我觉得之前已经覆盖过很多名字了，比如$VPG或Harmonic Drive。但可笑的是，CPO玩家如$SIVE其实是前沿物理AI开发的核心部分。
英文原文
Fun fact: Lot of the same companies are often used across different supply chains. One likely example is: $SIVE as the upstream laser supplier to Boston Dynamics via: Sivers -> $AEVA FMCW (CW DFB lasers) -> LG Innotek -> Boston Dynamics. I actually personally liked Aeva for 4D AI first. Just so happened to find out Sivers was their high confidence laser supplier for 4D FMCW lidar. So you actually get robotics exposure with photonics while the same CW lasers used for hyperscaler AI DCs. Near term revenue ramp though it's probably $SIVE supplying laser volume ramp for $NVDA self-driving car related architectures though Aeva. Humanoids are probably later in 2028? You can always get more indirect exposure like MU with memory or $INTC with edge CPUs, but of course there's more direct exposure out there. Think I've already covered a lot of names in the past like $VPG or Harmonic Drive. But hilariously enough CPO players like $SIVE are a core part of frontier physical AI development.

看好Harmonic Drive，但更倾向用资本支持西方供应链而非中国。
我确实看好 Harmonic Drive (6324) 作为西方谐波减速器领域的领导者，估值约 42 亿美元。在机器人/人形机器人的物料清单价值中占非常大比重。我实际上更看好 Leader Drive（因为大规模生产更便宜，覆盖更多零件）。也许三花(Sanhua)会是 $TSLA Optimus 的供应商。但用我的资本，我更偏好支持西方供应链而非中国供应链。这不仅仅是赚市场的钱，还关乎你想达成什么目标（帮助推进美国供应链和机器人行业领导者）。
英文原文
I do like Harmonic Drive (6324) as the Western Leader (eg. harmonic reduction gear) at ~$4.2B MC. Very large part of robotics/humanoid BOM value. I actually like Leader Drive more (since it's cheaper for mass production, covers more parts). And maybe Sanhua for $TSLA Optimus. But prefer to advance Western supply chains with my capital over ones in China. It's not just profiting off markets, but what you want to get accomplished as well (helping advance US supply chains and Robotics leaders).

看好 Harmonic Drive 的人形机器人敞口
我觉得 Harmonic Drive（6324）是 GS research report 里列出来的人形机器人敞口里比较好的一个，估值大约 40 亿美元。 我个人也买了一些，作为敞口。 中国竞争对手也许会被用于大规模生产。 但我个人更偏好投资西方供应链，并把它们扶起来。

梳理机器人供应链瓶颈，看好TKR、SYSS等美国本土替代标的。
波士顿动力/Optimus/机器人供应链摘要(TLDR)： - $ALGM ($65亿) 电机/传感 (Optimus) - $NOVT ($47亿) 反馈 (Atlas, Figure) - $VICR ($65亿) 电源 (Atlas) - $OUST ($16.4亿) 激光雷达(LiDAR) (Spot, Atlas) - $AMBA ($27亿) - 芯片 (Atlas, Figure) - $AEHR ($8.12亿) - 碳化硅(SiC)测试 (t2) - $RRX ($105亿) - 关节 (Agility, Apollo) - $TKR ($65.3亿) - 谐波应变 (t2) - $MP ($118.2亿) - 钕镨磁铁 (t3) - $LSCC ($116亿) - 传感器融合FPGA (t3) 我个人的持仓： - $SYSS ($9.98亿) - 骨架 (Optimus, Atlas, Figure) - $LPTH ($7.01亿) - 视觉 (T2) 在OpenAI昨日推进机器人业务后，我研究了这些公司，并想以摘要格式分享发现。 再次强调，机器人原始设备制造商(OEM)通常不公布物料清单(BOM)，因此大多数已确认，部分未确认但通过交叉引用公开资料极可能属实。 但我们应看到机器人行业在2026-2027年迎来拐点。 思考： - 哈默纳科(Harmonic Drive Systems, 6324.T)。我此前将其视为领导者，但他们刚被中国Leaderdrive以40%更低成本复制技术所颠覆。 - 基于此，$TKR (美国)可能是最具“超额收益(alpha)”的标的，因为通过收购Cone Drive，他们成为相对于哈默纳科/Leaderdrive的主要美国谐波齿轮供应商。 - $AMBA和$VICR可能是我在美国供应链中发现的除$SYSS外最有趣的标的。 - 我选择$SYSS作为机器人瓶颈敞口的首选，因为他们是每个量产人形机器人的骨架/材料（例如已知用户包括波士顿动力Atlas），且拥有有效的美国认证垄断地位。 - $LPTH碰巧也是机器人瓶颈敞口，因为我购买它也是出于对国防部/军事瓶颈敞口的考虑。 这些只是美国大规模量产中“雷达下”的标的。除了两个持仓外，我不持有其他任何标的，但我仍在研究它们。 不幸的是，许多供应链如$TSLA的执行器（与三花智控的6.85亿美元订单）仍在中国。但我预计许多将回流美国，因此仍在寻找供应链BOM方面的超额收益。 如果我遗漏了任何标的，欢迎补充。
英文原文
Boston Dynamics/Optimus/Robotic supply chains TLDR: - $ALGM ($6.5B) motor/sensing (Optimus) - $NOVT ($4.7B) feedback (Atlas, Figure) - $VICR ($6.5B) power (Atlas) - $OUST ($1.64B) LiDAR (Spot, Atlas) - $AMBA ($2.7B) - Chips (Atlas, Figure) - $AEHR ($812m) - SiC Test (t2) - $RRX ($10.5B) - Joints (Agility, Apollo) - $TKR ($6.53B) - Harmonic Strain (t2) - $MP ($11.82B) - NdPr magnets (t3) - $LSCC ($11.6B) - Sensor Fusion FPGAs (t3) I'm personally in: - $SYSS ($998M) - Skeleton (Optimus, Atlas, Figure) - $LPTH ($701M) - Vision (T2) Was researching these companies after OpenAI's push into robotics yesterday and wanted to do a TLDR format of findings. Again, robotics OEMs generally don't publish BOMs, so most of these are confirmed but some are unconfirmed but very likely from cross-referencing public findings. But we should see an inflection point for robotics going into 2026-2027. Thoughts: - Harmonic Drive Systems (6324.T). Was tracking this as the leader but they just got disrupted by China's Leaderdrive that copied their technology and at 40% lower cost. - Based on this, $TKR (US) is probably the most "alpha" up there since through Cone Drive acqusition, they're the primary US-based provider of harmonic gearing vs. Harmonic Drive / Leaderdrive. - $AMBA and $VICR are probably the most interesting ones outside of $SYSS that I've found in the US supply chains. - I picked $SYSS as my choice for robotics bottleneck exposure since they're the skeletons/materials for each humanoid on scale up (eg. with Boston Dynamics Atlas as known users) and effective US certification monopoly. - $LPTH happened to be a coincidental Robotics bottleneck exposure since I bought this for DoD/military bottleneck exposure too . These are just the "under the radar ones" in the US for the mass production scale-up. Don't own any of them aside from two, but I'm still looking into them. Unfortunately many supply chains like $TSLA's actuators ($685M order with Sanhua) are still in China. But I expect many of them to flow back to the US, so still looking for alpha in terms of supply chain BOM. If I missed any feel free to mention others.
