Nord Drive Systems has its successful "Nordbloc.1 "series extended to single-stage gearboxes for high-speed and high-torque applications. The new helical gearboxes are very efficient and offer high torsional rigidity, low operating noise and a long service life. In addition, thanks to the wash-down design, they meet the highest standards of hygiene.
The gearboxes do not require any joints and caps. This increases product stability and at the same time creates a smoother surface on which neither liquids nor solids can collect.
The FEM-optimized block housing guarantees maximum strength and rigidity. The structure with internal reinforcements and the increase in stiffness of the gearbox housing ensure particularly quiet running. All bearing and seal seats are included in the casting. Dividing joints, which can weaken the housing and promote oil leakage, are eliminated. Holes and mounting surfaces are manufactured in one clamping; The resulting close tolerances ensure the exact arrangement of gears, bearings and seals and an increased life of all components safely. The housing is made of high-strength, corrosion-resistant aluminum and therefore very light and robust. Additional protection is provided by the optionally available surface finish "NSD Tuph". The smooth, easy-to-clean housing surface makes the Nordbloc.1 gearboxes particularly suitable for users in hygiene-critical sectors such as the food or pharmaceutical industry.
The bearings are generously dimensioned and can absorb high axial and radial forces. A side effect of the large bearings are the larger diameter of the internal shafts, which increases the strength of the bearings. The gears are made of case hardened steel and allow a high short term overload. Five motor power ratings from 0,12 to 7,5 kW for output torques up to 280 Nm are available. All variants are available both in a foot and in a flange (B5 or B14) or in a foot / flange version. Options for IEC and Nema motor attachment as well as numerous equipment variants for shafts, bearings and lubrication can be flexibly implemented.
Robust, efficient, quiet and compact: The single-stage Nordbloc.1 spur gears provide a reliable, robust and cost-effective drive solution for pumps, mixers and fans as well as applications in conveyor technology.
