Copy of TORQUE LIMITER APP

A positioning arm that held a panel in place as it was attached to the wing assembly of an aircraft was already in use when a problem was discovered. Overload placed on the panel was traveling through the drive train to the motor. Thinking outside the box, Mach III’s engineering team devised a solution that fit within the existing drive system.

Hand Adjustable Torque Limiter

clock May 20, 2018 07:30 by author Mach III Clutch

T4Q1R-001_highres_outlinedThis torque limiter is used as a tension brake. The operator uses the knurled adjustment knob to vary the tension on a roll of film as it is unwound and applied to an architectural panel. The unit is constructed on a solid drive hub that extends from the unit and has a half inch wide and deep slot output to accommodate the tang on the core chuck.

Other configurations of this design are possible so if on-the-fly adjustment would be a benefit in your application, contact our factory based engineering and design team. All Mach III products are made in the USA and lead times for custom designs average less than 4 weeks.

Torque Coupling with O-Ring/Retainer Pin Connections Enables Quick Socket Changeovers and Prevents Stripped Threads

clock February 1, 2017 02:45 by author Mach III Clutch

O-Ring_Connected_Torque CouplingUsed for installing switching mechanisms on railway lines, the drill press to which this torque limiting coupling is attached sinks large screws into railroad ties made of various materials such as steel, concrete, plastic and wood. Each material requires a different size of screw and a different amount of drive torque. The railroad workers are able to manually adjust the slip torque setting of the coupling to the value needed for each material by loosening or tightening the adjustment nut. The output shaft allows for the quick interchange of sockets to accommodate the various screw sizes.

Mach III provides rapid turn-around for application adapted designs. This torque limiter was designed and quoted within 24 hours of the initial discussion between the client and our engineers. The units were manufactured within 3 weeks.

Custom Design Solutions: Food Safe Torque Limiter

clock June 4, 2016 10:18 by author Mach III Clutch

T4B2H-003_1This slip clutch was developed for an application where a food product is pulled through processing machinery by a wheel. Since there is a possibility of the food becoming jammed in the wheel, a torque limiter was need to protect the drive train that would be wash down compatible and meet food safety standards.

Key Features of the Mach III custom design solution:

  • Torque Capacity: 2029 pound inches @ 50% spring compression
  • Totally enclosed, sealed, stainless steel construction 
  • Bore Size:  1.0 Inch with Standard Keyway

Slip Clutch Adapted For Diameter Restriction

clock September 16, 2015 06:14 by author Mach III Clutch

T4A4H-001_highres_outlinedThis mechanical friction torque limiter was created in response to a customer’s request for a slip clutch with a 3180 pound inch setting and a 44L100 pilot mounted pulley. The first challenge of this application was that the outside diameter of the torque limiter could not exceed the diameter of the pulley. Mach III designed this unit with eight friction surfaces to deliver the required torque within the diameter restriction. 

The second challenge was that the unit had to fit on a 1.25 Inch shaft.  The design could accommodate a 1.25 inch bore, but there was no room for a keyway.  Mach III extended the drive hub and fitted it with a locking collar to connect the torque limiter to the shaft.

Torque Limiter Coupling Connects Square Shafts

clock October 14, 2014 17:38 by author Mach III Clutch

T4Q2H-001 FrontUsed on to raise and lower an antena on a military vehicle, this torque limiter coupling is exposed to the elements. Stainless Steel contruction assures that it up under the harsh conditions. The torque limiter portion fits a 1.0 Inch Square, the coupling portion fits a 0.75 Inch Square. The torque limiter protects the driven shaft by slipping if the factory torque setting of 1,800 pound inches is exceeded while the antena is raised.

Torque Limiter with Bearing Supported Coupling

clock January 21, 2014 05:05 by author Mach III Clutch
 

Mach_III_V6G2G-001_Torque LimiterAt Mach III, we try to find balance between due diligence regarding new applications and driving our customers and prospects crazy with questions, but this is one example of where it prevented a costly mistake.  This design evolved from an order for the  V6G1G-STL torque limiter mechanism with coupling.  The catalog model was chosen by the end user after consulting Mach III’s website and the company tasked with building the equipment ordered what was specified. 

At the time of the order, however, there were several red flags that led to contact between Mach III’s engineering team and the project engineer.  Their discussions and a review of layout sketches revealed that V6G1G-STL was unsuitable as there was no support for the coupling shaft and the unit did not have the required torque capacity.  The unit which resulted, V6G2G-001 pictured above, includes a rigid coupling with internal bearing to pilot the 1.75 Inch drive shaft and support the 2.0 inch coupling shaft.  It has a torque capacity of 8,777 pound inches, almost 3 times more than the model originally chosen.

Taming the Gorilla

clock November 18, 2009 11:41 by author Mach III Clutch

Mach III was contacted by a facility which uses large manually operated control valves. The quarter-turn valves are driven through right angle worm reducers by hand operated chain wheels. Due to the unfortunate fact that human beings are not equipped with torque sensors in their muscles, costly downtime failures were occurring when excess force was applied to the worm reducer via the chain wheel. Working with the facility's engineer, Mach III designed a special, keyless, friction torque limiter to connect the chain wheel to the reducer shaft. 

T4B2H-001 with Chain Wheel AssemblyIn addition to designing and manufacturing the torque limiter, Mach III also provided the customer with a mounting diagram including suggested dimensions for machining their existing chain wheel to accept the new device. Although Mach III offers the service of machining existing mating components, in this case the customer's shop felt comfortable with the task. The torque limiter was successfully installed and adjusted to a setting where it would slip to protect the worm reducer when the shop gorilla swings on the chain.

Those accustomed to working with other clutch suppliers might assume that only an application promising considerable quantities would merit this level of attention. But this customer needed only three torque limiters, and spent just about one thousand dollars. So what is the motivation? A report from the customer that the new system "worked perfectly".

If  you've got a nagging issue needing a clutch, brake or torque limiter solution and are concerned that no one will think it's worth their while, give Mach III a call. We know you will be pleasantly surprised.
