Industrial Gear Unit

We are offering NORDBLOC industrial gear units that are designed and developed according to the tried-and-tested UNICASE housing principle. All the bearings are integrated to one-piece housing and features highest levels of precision, rigidity and strength. These gear units allows the shaft axes to be staggered, resulting in a more compact design which allows the use of larger roller bearings to guarantee a long operating life.

Some of the advantages of unicase housings are as follows:

• Optimum sealing

• Quiet running

• High torque capacity

• Increased lubricant life

• Maximized operating life of bearings and gears

• High reliability

• Long operating life

• Symmetrical design

• B14 face as standard on output side

• 6 installation configurations

• Mirror-image installation possible

• Same housing size, installation dimensions for all ratios (2 and 3 stage)

Some of the specifications are as follows:

NORD industrial gear units have been developed according to the tried-and-tested unicase housing principle. The unicase is a one-piece housing, into which all the bearings are integrated. The finishing of this unicase is carried out with in unique jig, on state-of -the-art CNC machines. The unicase concept features highest levels of precision, rigidity and strength. There are no dividing seams between the drive and the gear unit housing which are subjected to transverse forces or torque. The unicase principle allows the shaft axes to be staggered, resulting in a more compact design which allows the use of larger roller bearings to guarantee a long operating life.

Advantages of unicase housings:

• Optimum sealing

• Quiet running

• HIgh torque capacity

• Increased lubricant life

• Maximized operating life of bearings and gears

• High reliability

• Long operating life

• Symmetrical design

• B14 face as standard on output side

Gear Unit Housing with Smooth Surface

• Series SK 1SM... worm gear units were developed according to the block housing principle.

• The SM – worm gear motor is encased in a single-piece aluminium housing with extremely smooth external contours, faciliating easy cleaning as dirt is not quickly deposited.

• All bearing points are integrated into the block housing. The housing is a single whole and not separated. This principle enables the highest degree of manufacturing accuracy, as all machining is completed in one chucking operation. Extreme rigidity and stability distinguish the block housing concept. There are no joints between the output end and the gear unit housing to be subject to lateral or torque force loading.

• The gear ratios are virtually identical to the NORD worm gear unit series SI,SIS,and SIS-D.

Worm Geared Motors

The universal worm gear unit si represents a homogeneous gear module. The single-piece aluminum die cast housing has no cover or sealing joints. The rigid housing block ensures the highest degree of operational safety even with the highest load capacity. This variable worm gear range features a modular design. The iec/nema motor mountings in connection with the helical pre-stage form completely mounted gear modules that can be easily assembled.

A variety of individual gear designs can be combined from few modules. The universal worm gear unit si features as standard foot mounting on three sides, b14 flanges on two sides and an output hollow shaft. Modules that enable various applications of the gear series are plug-in solid shafts, output-side bolt-on type flanges, torque arms or helical gear pre-stages.
