Efficiency gains are achieved through multi-start, while using the latest Gearbox Backstop patent to allow the gearbox to be locked.
The overall efficiency of the gearbox is increased by 200% to 300% while optimising costs.
Conventional worgears need to take into account the self-locking characteristics and must maintain an inherent machining angle. STARD AUTOMATION utilizes a patented locking device called Backstop to make high efficiency wormgears self-locking.
Electric applications can be optimised with STARD high efficiency worm gears for faster shutdown times. Manual applications can also be optimised for fewer operating turns, larger manually operated valve pass diameters and lower installation and maintenance costs.
