Product Announcement from Mach III Clutch, Inc.
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.
In 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 excess force is applied to the chain wheel.
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.
