Dieter Rams, the father of German work design, once said: “Excellent design is concise.” The great Jobs is also a minimalist. Even when I wait for these products, Wang people are also pursuing minimalism in some of their products. What is this~~ “You exist, in my deep mind, in my dream, in my heart, in my…
Commenting on a product, everyone can dig out its performance in all aspects, such as whether the user experience is good, whether the function is perfect, whether it solves the user’s pain points, etc… But in this, which one determines the core of the product Competitiveness? Features The function directly affects the user’s operation and…
Many designers are used to using their own experience and subjective feelings to propose solutions, but experience and subjective feelings are likely to be wrong. User-centered design needs to be implemented based on objective facts related to user psychology and user behavior, rather than the designer’s “self-reference”. Don’t say “I think…” Many designers are used to…
Today, I was pissed off by 400 calls. Without warning and prior notice, the service was suspended due to insufficient balance.

It is said that the service is generally restored within 24 hours……
In order to attract the attention of capital, entrepreneurs and CEOs in the technology industry have spent a lot of attention on visual design, trying to create beautiful products and brands with very cool images.

Lasting creativity does not come from a flash of light or an afternoon of inspiration. We should regard innovation as a daily habit, just like laying a good foundation for everything. At 99U, we have summarized the common characteristics of innovators that are worth learning from many entrepreneurs, researchers, and creative workers, and help everyone cultivate: 1….
The essence of “simplicity” does not lie in what elements are used, but it reduces our cognitive burden. When we say that an advertisement is well done, it does not mean that it is brilliantly literary, beautiful in pictures, and outstanding in special effects, but that it can hit the hearts of target audiences in…
American psychologist Maslow once put forward the theory of human needs hierarchy. He divided human needs from low to high into five categories: physiological needs, safety needs, social needs, respect needs and self-actualization needs. Maslow’s hierarchy of needs has pointed out an effective way for us to analyze the needs behind the product. For any product…

在伺服应用中选择最适合型号联轴器的可能是一件令人困惑的事情，因为伺服系统选配联轴器是一个复杂的过程。这个过程包含了很多不同的性能因素，包括力矩、轴的偏差、硬度、转速、空间要求等等， 联轴器需要满足所有这些以便使系统正常的运转。在选择联轴器之前，需要我们对这些联轴器的性能和其应用进行详尽的了解。不同类型的联轴器存在着其自身的优缺点。 本文旨在向伺服联轴器的终端用户介绍不同类型联轴器在各种伺服系统中的应用，同时帮助终端用户指出在设计制造过程中要考虑的因素及如何有效连接不同产品来正确选择合适的联轴器。
交叉滚子轴承用于高精度工业机器人手臂和精密机床领域，尖端设备对轴承精度要求极高，NSK轴承专注于P5级以上高精度交叉滚子轴承研制，在此类轴承加工中，除了零件尺寸精度需要达到要求外，轴承装配也很重要，交叉滚子轴承装配要点之轴承合套做下介绍。 精密较长自行车合套定义：将预先加工好的轴承套圈和滚动体以及隔离块组合配套并组装，达到设计游隙以及启动力矩的过程，此过程主要分为三个步骤： 一、.交叉滚子轴承磨加工配套：轴承终磨完成前对交叉滚子轴承进行内外圈配套，这是为轴承最后组装预先排号，减小装配测试游隙工作量，在轴承终磨时，磨工记录轴承滚道尺寸，并根据滚子尺寸计算游隙大小，达到或接近设计游隙即可对对应套圈编号记录，工后续装配查阅； 二、交叉滚子轴承组装测精度及力矩：游隙合适的轴承配套编号并测量旋转跳动值、装配高度以及启动力矩，并检查外观，各项指标合格后轴承装密封圈+注脂，确保轴承旋转灵活即为成品出货。 三、交叉滚子轴承装配试游隙：轴承套圈完成磨加工进入装配车间后，装配人员在恒温车间根据原始磨加工尺寸选择滚子进行试装，螺栓预紧后用仪器测量实际游隙，如果游隙合适进入下流程，否则更换滚子或者返修套圈。
5大件都有啥作用呢？ ①内圈通常与轴紧配合，并与轴一起旋转。 ②外圈通常与轴承座孔或机械部件壳体配合，起支承作用。但是在某些应用场合，也有外圈旋转，内圈固定，或者内、外圈都旋转的。 ③滚动体借助保持架均匀地排列在内圈和外圈之间。它的形状大小和数量直接影响轴承的承载能力和使用性能。 ④保持架将滚动体均匀隔开，引导滚动体在正确的轨道上运动，改善轴承内部载荷分配和润滑性能。 ⑤用于机械的摩擦部分，起润滑和密封作用。也用于金属表面，起填充空隙和防锈作用。 构成原理 一、轴承套圈 轴承套圈结构 1. 内圈( inner ring)：滚道在外表面的轴承套圈。 2. 外圈 (outer ring):滚道在内表面的轴承套圈。 3. 圆锥内圈( cone):圆锥滚子轴承的内圈。 4. 圆锥外圈( cup):圆锥滚子轴承的外圈。 5. 双滚道圆锥内圈 (double cone):有双滚道的圆锥滚子轴承内圈。 6. 双滚道圆锥外圈 (double cup):有双滚道的圆锥滚子轴承外圈。 7. 宽内圈( extended inner ring):在一端或两端加宽的轴承内圈，以便改善轴在其内孔的引导或安装紧固件或密封件提供补充位置。 8. 锁口内圈 (stepped inner ring):一个肩全部或部分被去掉的沟型球轴承内圈。 9. 锁口外圈 (counterbored outer ring):一个肩全部或部分被去掉的沟型球轴承外圈。 10. 冲压外圈 (drawn cup):由薄金属板冲压，一端封口（封口冲压外圈）或两端开口的套圈，一般指向心滚针轴承的外圈。 11. 凸缘外圈( flanged outer ring):有凸缘的轴承外圈。…
一、滚动轴承的主要类型、性能与特点按滚动体的形状，滚动轴承可分为球轴承和滚子轴承。 按接触角 的大小和所能承受载荷的方向，轴承可分为： 1、向心轴承： 公称接触角：0° 45°，向心轴承又可细分为： A、径向接触轴承： ＝0°，只能承受径向载荷(如圆柱滚子轴承)，或主要用于承受径向载荷，但也能承受少量的轴向载荷(如深沟球轴承)； B、向心角接触轴承：0°< 45°，能同时承受径向载荷和单向的轴向载荷(如角接触球轴承及圆锥滚子轴承)。 2、推力轴承： 公称接触角：45°< 90°，推力轴承又可细分为： A、轴向接触轴承： ＝90°，只用于承受轴向载荷； B、推力角接触轴承：45°< <90°主要承受大的轴向载荷，也能承受不大的径向载荷。 按自动调心性能，轴承可分为自动调心轴承和非自动调心轴承。 滚子轴承的类型很多，现将最常用的几种滚动轴承的性能和特点作一简要介绍。 1、圆锥滚子轴承 能承受较大的径向载荷和单向的轴向载荷，极限转速较低。 内外圈可分离，故轴承游隙可在安装时调整，通常成对使用，对称安装。适用于转速不太高、轴的刚性较好的场合。 2、深沟球轴承 主要承受径向载荷，也可同时承受少量双向轴向载荷，工作时内外圈轴线允许偏斜8′～16′。摩擦阻力小，极限转速高，结构简单，价格便宜，应用最广泛。但承受冲击载荷能力较差。适用于高速场合，在高速时，可能来代替推力球轴承。 3、推力球轴承 推力球轴承的套圈与滚动体多半是可分离的。有单向和双向之分。 单向推力球轴承只能承受单向轴向载荷，两个套圈的内孔不一样大，内径较小的是紧圈，与轴配合，内孔较大的是松圈，与机座固定在一起。极限转速较低，适用于轴向力大而转速较低的场合。 双向推力球轴承可承受双向轴向载荷，中间套圈为紧圈，与轴配合，另两套圈为松圈。高速时，由于离心力大，球与保持架因摩擦而发热严重，寿命较低。常用于轴向载荷大、转速不高处。 4、圆柱滚子轴承 只能承受径向载荷，不能承受轴向载荷。承受载荷能力比同尺寸的球轴承大，尤其是承受冲击载荷能力强，极限转速较高。 5、调心球轴承 用于承受径向载荷，也能承受少量的双向轴向载荷。外圈滚道为球面，具有调心性能，内外圈轴线相对偏斜允许0.5°～2°，适用于多支点轴、弯曲刚度小的轴以及难于精确对中的支承。 6、滚针轴承 这类轴承采用数量较多的滚针作滚动体，一般没有保持架。径向结构紧凑，且径向承载能力很强，价格低廉。缺点是不能承受轴向载荷，滚针间有摩擦，旋转精度及极限转速低，工作时不允许内、外圈轴线有偏斜。常用于转速较低而径向尺寸受限制的场合。 7、推力调心滚子轴承 可以承受很大的轴向载荷和一定的径向载荷。滚子为鼓形，外圈滚道为球面，能自动调心，允许轴线偏斜 2°～3°，转速可比推力球轴承高，常用于水轮机轴和起重机转盘等。 8、角接触球轴承 能同时承受径向载荷与单向的轴向载荷，公称接触角α有15°、25°、40°三种。α越大，轴向承载能力也越大。通常成对使用，对称安装。极限转速较高。适用于转速较高、 同时承受径向和轴向载荷的场合。
膜片联轴器的选用方法 1、 膜片联轴器至少由一个膜片和两个轴套组成。膜片被用销钉紧固在轴套上一般不会松动或引起膜片和轴套之间的反冲。有一些生产 商提供两个膜片的，也有提供三个膜片的，中间有一个或两个刚性元件，两边再连在轴套上。 2、 膜片联轴器这种特性有点像波纹管联轴器，实际上联轴器传递扭矩的方式都差不多。膜片本身很薄，所以当相对位移荷载产生时它 很容易弯曲，因此可以承受高达1.5度的偏差，同时在伺服系统中产生较低的轴承负荷。 3、 膜片联轴器常用于伺服系统中，膜片具有很好的扭矩刚性，但稍逊于波纹管联轴器。 4、 另一方面，膜片联轴器非常精巧，如果在使用中误用或没有正确安装则很容易损坏。所以保证偏差在联轴器的正常运转的承受范围之 内是非常必要的。 5、根据轴径调整型号： 初步选定的轴承联轴器联接尺寸，即轴孔直径d和轴孔长度L，应符合主、从动端轴径的要求，否则还要根据轴径d调整联轴器的规格。 主、从动端轴径不相同是普通现象，当转矩、转速相同，主、从动端轴径不相同时，应按大轴径选择联轴器型号。新设计的传动系统中， 应选择符合GBT3852中规定的七种轴孔型式，推荐采用J1型轴孔型式，以提高通用性和互换性，轴孔长度按i轴承联轴器产品标准的规定。
