NORD helical bevel gearboxes for residue-free cleaning

NORD Drivesystems has developed a family of two-stage, helical bevel gearboxes designed for easy and residue-free cleaning. The company says the washdown gear units have no indentations or dead spaces where dirt or liquids could accumulate.

The gearboxes’ smooth surfaces enable cleaning liquids to be easily washed off in all installation positions. The systems can withstand frequent, intense, aggressive cleaning with acid and alkaline solutions. Manufactured from die-cast aluminium, they resist corrosion better than steel models, NORD claims.

The family comprises five sizes with torques from 90 to 600 Nm, all of which are available as closed or lightweight open versions. NSD tupH, a sealed surface conversion system, makes the aluminium drives as robust as their stainless steel counterparts and many times more durable than anti-corrosion paints, says NORD.

The product range includes hygienic, reliable, wet cell versions of geared motors. Modifications available include extended temperature operation, protective finishes and special lubricants.

A line of SK 200E frequency inverters for distributed installation are available in four sizes, from 0.25 to 22 kW. The devices can adapt to a range of requirements, with options including AS-interface and the safety function ‘safe torque off’. Two analog inputs, that allow for variable speed adjustment and can actively and autonomously control process values, are available.
