离合器和刹车除了扭矩限制器随着对持有，停止和索引的新应用程序的要求继续发展。这些技术针对特定应用的趋势的持续趋势持续不断，尤其是随着多个行业超越了旧股票零件的能力。
“马赫三世经历了强烈的应用lication inquiries for miniature clutches, brakes, and torque limiters. In 2019, we had 14 new projects requiring a miniature clutch, brake, or torque limiter — more than in the prior three years combined,” explains president of Mach III Clutch Inc. Lesli Riehemann.
“So far, we’ve started two new miniature projects in 2020 — one of which is a brake that is only 0.78 O.D. x 1.75 in. long. Mach III defines miniature as requiring a 2-in. or smaller friction diameter, and a bore or shaft size of a half inch or less. Our assembly technicians joke that may need to get in touch with Santa’s workshop to subcontract assembly of these miniature products to the elves.”
Shown here is a custom design from Mach III with quarter for perspective. This brake provides tension on the filaments used to make false eyelashes.
• Torque rating of 15 lb-in. at 80 psi
•2.58英寸O.D.和1.27英寸。总长度
•0.50英寸的轴尺寸为0.125英寸。
该自定义的C面摩擦制动器为持有应用程序开发，连接到Allen Bradley Servomotor和Apex行星变速箱。它的低背部设计操作至5,000 rpm。
• Torque rating of 90 lb-in.
•3.94英寸。O.D.和3.78英寸。外壳长度
•连接包括12毫米的输入孔，带夹具项圈和12毫米输出轴
这是从正面和侧面的定制马赫III摩擦扭矩限制器，并以四分之一的视角显示。开发了该扭矩限制器以保护车辆内部的电动机 - 进而容纳相机以检查地下管道。
• Max slip torque setting is 70 lb-in.
• 1.275-in. O.D. and 0.58-in. overall length
Mach III的这种不锈钢扭矩限制器是用于使用齿轮箱装有电动机操作舵的自动帆船上的。为了防止在舵上捕获某些东西时，轴破裂了，该限制器将滑落直到对象清除。
• Max slip torque setting of 190 lb-in.
• 2.69-in. O.D. and 2.44-in. overall length
• Connections include two 10-mm shafts with 3-mm keyways
物联网即将刹车和离合器
In an entirely different development, Andrew Lechner of R+W (who details his company’s new informative coupling in the couplings section of this Design World Trend issue) mentioned a similar IoT functionality that may soon come to a new line of torque limiters from the component manufacturer.
Interestingly enough, we’re also known for ball-detent torque limiters. These are mechanical-overload release devices that (like couplings) install close to the business end of motion axes. Sensors here would be better at monitoring the machine performance than systems tracking amp draw at the motor. That’s why we may soon incorporate sensors into torque limiters as well.
实际上，设计工程师通常会猜测机器轴上机械扭矩限制器的适当断开设置。将传感器嵌入这些扭矩限制器中实际上可以帮助机器构建器对其安全性分离设置进行微调……更好地在需要机器关闭的可接受轴扭矩和扭矩之间行走。借助这样的组件，工程师将获得扭矩监控和安全性突破，这与扭矩超载保护一样强大。
