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.

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.
