A company that produces “Vibration Monitoring Instrumentation for Rotating Machines” asked Helical to help them devise a unit that would act similar to an encoder. They wished to incorporate an incremental counting method into this unit. The customer was using a rubber type coupling and modifying it to use in measuring phase position and shaft speed.
The Solution
By using a standard WAC25 coupling as a base, the 20 cogs (18° steps) and the .25-in. wide slot for an absolute point were all combined into a homogeneous piece of material. This is another example of the versatility of integrating multiple pieces and operations into a HELI-CAL Flexure. This was accomplished in a relatively short period of time, only 3 months. The coordination between the salesman, customer’s engineer, and our application engineer helped move this project along. There were four various samples provided to the customer before they decided on a final configuration.
