Tektrend has been assembling and retrofitting ultrasonic scanning systems for more than a decade. The traditional approach used during many years for transducer rotational motion control has been called swivel-gimbal or gimbal-gimbal assembly.
The so-called “swivel-gimbal” (A-B axes) was typically implemented using motors installed outside the immersion bath mounted on top of the Z-axis. Having the A and B motors in that location was convenient because there was no need to submerse them. However, this traditional concept required long axial rods to provide transmission to the gears installed underwater.
Maintenance on the A and B axes typically requires the removal of the full Z-A-B assembly. Therefore, retrofit was only available by replacing the full Z-A-B assembly.
| The questions then became “How could we improve this situation”. How could we escape the traditional mind scheme?” |
Following 2 years of research and development, Tektrend proudly releases its new, original gimbal-gimbal component.
This motorized device has been designed to be fully immersed. The motor transmission is local to the encapsulation, which improves accuracy, rigidity and weight. Achieving this was quite a challenge for our engineering staff.
Finally, having
incorporated
position encoders,
integrated limit
switches and
standard UHF
connectors for the
UT transducer,
Tektrend has
achieved a truly
compact and tight
environment.
This new concept allows for high-speed rotational motion. It also allows for easier retrofitting. Tektrend has the capability of manufacturing the unit as Gimbal-Gimbal or Swivel-Gimbal. Each configuration is sold separately.
