MAXXDRIVE industrial gear units from NORD DRIVESYSTEMS are designed to handle heavy-duty applications such as bucket elevators, agitators, conveyor belt drives, mixers, mills, drums, crushers, and more. The product family is available in a parallel shaft design as well as a right-angle design.

Constructed according to the UNICASE housing principle in which all bearings and seals are contained within a single casting, the robust gear units are optimized to ensure excellent load capacity, long service life, long bearing life, quiet operation, and are lower in weight than jointed housing gear units. The industrial gear units additionally offer many modules, input options, and output options for high versatility and adaptability to a wide range of applications.

MAXXDRIVE industrial gear units offer a combination of flexibility and durability. They feature mounting surfaces on six sides of the drive for versatile mounting configurations and flexible integration into installation spaces. As a standard, the gear units are equipped with an efficient NBR or FKM sealing system that is suitable for many environments. For specific ambient conditions, optimized sealing systems incorporating gamma-ring, labyrinth, and Taconite seals are also available.

Standard compact MAXXDRIVE industrial gear units include MAXXDRIVE parallel industrial gear units and MAXXDRIVE right-angle industrial gear units. MAXXDRIVE parallel industrial gear units have 11 case sizes to choose from and offer a torque range up to 2,495,900 lb.-in, performance up to 8,075 hp, and 2-stage or 3- stage gearing options. MAXXDRIVE right-angle industrial gear units also have 11 case sizes available but in 3-stage and 4-stage gear reductions with output torque up to 2,301,200 lb.-in and performance up to 2,850 hp.

UNICASE housings and high precision bevel gearing

Both designs are durable thanks to UNICASE housings and high precision bevel gearing. High quality, low friction bearings and large center distances ensure significant load capacity and reliable automation. Reinforced output bearings with a spread bearing design and dry cavity are also available for applications requiring increased bearing load capacities and additional oil leak protective measures such as agitators or mixers.

MAXXDRIVE XD parallel gear units have 10 case sizes available in 3-stage or 4-stage reductions and like the MAXXDRIVE parallel gear units, deliver output torque up to 2,495,900 lb-in and performance up to 8,075 hp. These industrial gear units are engineered to meet the special requirements of crane and hoist applications, featuring a center distance increased by 35% compared to the compact MAXXDRIVE series. This extended distance enables maximum space for the motor and rope drum to be on the same side of the gearbox in a unique U-shaped arrangement ideal for lifting gear drives.

The housings are FEA-optimized for overhung load, especially downwards forces, and include an inspection cover on top of the unit for easy 1/3 maintenance and service access. Both 3-stage and 4-stage versions feature the same overall unit dimensions and center distances for a standardized design that reduces system variants and lowers the total cost of ownership.

Built for high speed and high power

MAXXDRIVE XT industrial gear units have been designed especially for applications requiring high speed ratios in combination with high powers. They offer a 2-stage, right-angle gear unit with a unique housing geometry optimized to achieve maximum thermal capacity. An efficient cooling fin design helps dissipate heat faster while an axial fan and air guide covers enhance airflow to prevent the unit from overheating at maximum power.

Thanks to their effective cooling abilities, these drives provide a robust solution in environments with demanding ambient conditions and large temperature fluctuations. The right-angle design additionally enables a symmetrical configuration for mirror image installations where space is limited and can also be mounted on a swing base depending on the application.

In addition to standard MAXXDRIVE options, NORD also offers an Endurance Package combining several protective measures that ensure drives will withstand challenging environments, such as those within the Grain industry. The five main components of the package include a drying agent filter, oil sampling point, quick fit filter trolley connection, oil inspection glass, and an additional quick fit filter trolley connection with an oil drain cock.
