Italian gearboxes boast 50% longer life
Italian gearbox manufacturer Varvel has developed a new range of inline helical gearboxes.
Although the application was somewhat different from those provided by NBC Group's normal customer base, the company was the ideal partner for the project because it acts as OEM agent for many of the worlds leading bearing and power transmission product manufacturers, and was able to design and provide the necessary items from its existing product portfolio.
The drive uses a Neri electric motor fitted with a permanent extra cooling fan and brake.
This is then fitted to a Varvel inline helical gearbox.
NBC Group then designed and manufactured a pinion for the output shaft of the gearbox to drive an externally geared 1m-diameter BRB slewing ring.
The design also incorporates a further 600mm-diameter BRB slewing ring to seat the structure on.
The ball rotates at 4rev/min, controlled by an Eexico inverter, and can be subject to winds reaching 46m/s (50kt for traditionalists).
The structure runs 24 hours per day, with a noise level of only 56dB.
NBC Group is now involved in a further innovative project for Blackpool seafront based on similar principles.
However, the end product has a far different use.
