Rack-and-pinion drive for injection molding machine - max. 400 kN

The POSIRACK line of rack-and-pinion drives has been built by PIV Drives since 15 years for the mold locking in many electrical injection molding machines. These drives with highest accelerating and decelerating torques are quiet running spur gearboxes featuring a compact construction with an integrated motor.
POSIRACK is a quiet running helical gear drive combined with spur gears and a dou-ble-toothed rack. Case hardened and profile-correction ground gears and rack ensure that high acceleration and brake torques will be safely transmitted. Performance opimized gear tooth forms handle bending and torsional loads while achieving optimal noise behavior through a high contact ratio factor. The sophisticated design ensures proper guidance of the rack within the gear unit. Optimized load sharing permits rack speeds up to 2000 mm/s.
These high efficiency rack and pinion drives allow to reduce your cycle times and create higher output volumes.

Parallel-shaft gear reducer / with extended center distance - i= 500:1 | POSIRED N

Lifting gears in which the cable drum and driving motor are arranged in parallel require a step-down gear with a correspondingly large axle base. The lifting gear gears in the POSIRED N series are designed for this application and ideally bridge the given distance between the motor and cable drum.
The development of this series was based on widespread experience in crane engineering. The demands of this branch were largely taken into account in this gear concept.
The accessories needed for this application such as elastic clutches, barrel clutches, brakes, substructures, etc. are available and can be supplied with the gear

Industrial gear reducer - 25.000 - 242.000 Nm, 2.2 kW - 1.000 kW

In accordance to the well-tested unicase housing principle, the NORD industrial gear units have been improved in which the unicase is carried out from a unique jig and the futuristic machines. It offers high amount of accuracy, stiffness and strength.

The unicase housing principle lets the shaft to be lurched due to its compactly-built features that allows the larger roller bearings that ensures a long life of operation.

These unique housings have advantages such as they run quietly with a high torque capacity along with their optimum sealing. They also have additional lubricant life that broadened the operating life of gears and bearings.

Mechanical speed variator - 0.25 - 110 kW, 6:1

The Unicase Belt Variator Geared Motors by Nord utilize constant axial pressure and a symmetrical pulley design to allow for optimal power transmission. It features an easy-to-use hand wheel that controls the motors speed.

The motor is housed in corrosion resistant, light-weight aluminum-alloy, with static conducting belts for added operational safety. The motor also has low inertia, energy-efficient pulleys made from special wear-resistant alloy.
The belt case may be opened without any special tooling for simple maintenance.

The Unicase Belt Variator Geared Motors is available in U-flow and Z-flow configurations, with motors using either analog and digital speed indicators available. An electric remote speed control is optional.

Mechanical speed variator - 0.12 - 4 kW, 7:1

These Helical Bevel-Geared Motors are available in a broad selection of motors and brake motors. These have analog or digital speed indicators with an easily-operated handwheel speed control as standard; electronic remote speed control is optional.

These motors encased in a rugged cast iron body use a corrosion-resistant, stainless steel lead screw and brass guides. Wear is minimized by their ground and polished driving discs and a special mechanism that transmits only the required torque. Disc material is non-hygroscopic and asbestos-free for safe and prolonged operation. Opening the case does not require special tooling thus enabling fast and easy maintenance.
