Clutches and brakes as well as torque limiters continue to evolve as the requirements for new applications for holding, stopping, and indexing continue to multiply. The ongoing trend for these technologies towards application-specific variations continues unabated \u2014 especially as several industries have exceeded capabilities of legacy stock parts.<\/p>\n\n\n\n

\u201cMach III has experienced a strong increase in application inquiries for miniature clutches, brakes, and torque limiters. In 2019, we had 14 new projects requiring a miniature clutch, brake, or torque limiter \u2014 more than in the prior three years combined,\u201d explains president of Mach III Clutch Inc.<\/a> Lesli Riehemann.<\/p><\/blockquote>\n\n\n\n

\u201cSo far, we\u2019ve started two new miniature projects in 2020 \u2014 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\u2019s workshop to subcontract assembly of these miniature products to the elves.\u201d<\/p>\n\n\n\n

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.
\u2022 Torque rating of 15 lb-in. at 80 psi
\u2022 2.58 in. O.D. and 1.27 in. overall length
\u2022 0.50 in. shaft size with a 0.125 in. keyway

This is a custom Mach III friction torque limiter from the front and side and shown with quarter for perspective. This torque limiter was developed to protect a motor inside a vehicle \u2014 in turn housing a camera to inspect underground pipes.<\/strong>
\u2022 Max slip torque setting is 70 lb-in.<\/strong>
\u2022 1.275-in. O.D. and 0.58-in. overall length<\/strong><\/figcaption><\/figure><\/div>\n\n\n\n

This stainless-steel torque limiter from Mach III was developed for use on an autonomous sailing vessel employing a gearbox-fitted motor to operate the rudder. To prevent the shaft from breaking when something is caught on the rudder, this limiter will slip until the object is clear.<\/strong>
\u2022 Max slip torque setting of 190 lb-in.<\/strong>
\u2022 2.69-in. O.D. and 2.44-in. overall length<\/strong>
\u2022 Connections include two 10-mm shafts with 3-mm keyways<\/strong><\/figcaption><\/figure><\/div>\n\n\n\n

IoT coming to brakes and clutches<\/h3>\n\n\n\n

In an entirely different development, Andrew Lechner of R+W (who details his company\u2019s 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.<\/p>\n\n\n\n

Interestingly enough, we\u2019re 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\u2019s why we may soon incorporate sensors into torque limiters as well.<\/p>\n\n\n\n

In fact, design engineers often guess at the proper disconnect settings for the mechanical torque limiters on their machines\u2019 axes. Embedding sensors in these torque limiters could actually help machine builders fine-tune their safety breakaway settings \u2026 and better walk that line between acceptable axis torques and torques that necessitate machine shutdown. With such component, engineers would get torque monitoring and safety breakaway, which is about as robust as torque-overload protection can get.<\/p>\n\n\n\n
