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

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.

Torque Limiter Coupling with Interchangeable Output

clock March 18, 2015 09:50 by author Mach III Clutch

Morse_Taper_Torque_Limiter_CouplingCommonly used to open and close gate valves in water treatment and irrigation systems, this friction torque limiter coupling connects to a power drill with a #3 Morse taper socket.  A variety of output options are available including different sized squares and keyed bores.   The coupling is pre-set at the factory to a torque value you specify and may be adjusted in the field if needed.  When the torque setting is exceeded, the coupling slips to prevent over tightening.

Torque Limiter Details

  • #3 Morse Taper Input
  • Weight:  7 pounds
  • 4.5 Inch Outside Diameter, Length Varies By Coupling
  • Torque Settings Between 10 and 233 Pound Feet Can Be Specified

Coupling Options Shown

  • Top:  1.0 Inch Bore with Standard Keyway and Set Screws
  • Left:  0.75 Inch Square
  • Center:  2.0 Inch Square (Fits 2 Inch Square AWWA Operating Nut)
  • Right:  0.75 Inch Bore with Standard Keyway & Set Screws
  • Coupling Weight:  1 – 2 pounds

Torque Limiter with Bearing Supported Coupling

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.
