PIV Drives has developed this range of rack and pinion drives for closing the mould of injection molding machines. This type of drive features quiet running spur gear reduction and presents a compact construction with an integrated motor. The POSIRACK design has a double-toothed rack output. Case hardened and ground gear wheels are the base for this high performance drive, with the industry’s best accelerating and decelerating torque and an extremely quiet package.
Technical Data:
Rack clamping force: up to 450 kN
Rack speed: > 2,000 mm/s

The advantages of our slew drives are:
-Handle simultaneously occurring radial, axial and moment loads
-Compact packages for space saving installations
-Maximum load capacity in compact design
-Extended life
-Reduced maintenance costs
-Easy to integrate into existing applications
-Modular construction allows very quick modifications

Drive systems for solar power systems: Due to their fixed south orientation, the solar irradiation angle of common solar systems is rather unfavourable in the mornings and the evenings: More than 35 % of the daily energy from solar power is lost.
To solve this problem, the solar module is automatically adjusted to the position of the sun in direction of both movement axes.
GFC AntriebsSysteme GmbH has developed special slewing gear units which provide the required high torque range.
From the development of application-specific drives and gear units to the serial production of the latter – with GFC, you can get everything from a single source. Before being shipped to the customer, the drives and gear units are measured and tested on our own test benches.

CVT
This steel-made high performance chain variator works with a constant power output while changing speed and torque. Variation of torque with constant power output, high efficiency with torque sensor, excellent perfor-mance from the utilization of high tech chains, independent speed control of driving and driven unit, and drive management with several driven units are key features of CVT applications.
POSICHAIN - Chain variable drives
The “classic” positive infinitely variable drives from PIV. Essential Features:
• Minimal maintenance expenses and high efficiency
• High control precision
• The qualities of the “torque-transformer” permit increasing torque with low speeds
• Extensive accessories

POSIDISC - Ball-discs variable speed drive
Easy maintenance and dependability under extreme operating conditions make this gear reducer the best choice for many applications. Speed adjustment is possible during operation as well as at idle. The mechanism is compatible with extreme operating conditions, including speed adjustment while the output shaft is locked. It is not necessary to use a starting clutch or a safety coupling.

The new HFUC Series component sets are a result of the continuous development of Harmonic Drive precision reduction gearing. In comparison with standard gears, the new HFUC series features a shortened Flexspline, which results in an important reduction of the axial length. The high performance IH tooth profile provides significantly increased torque capacity compared to gears incorporating the traditional involute gear tooth profile.
Advantages:
- High torque capacity
- Excellent positioning accuracy and repeatability
- Compact design
- High single stage ratios
- High torsional stiffness
- Zero backlash
- High efficiency
- Easy installation and assembly

This series of gear reducers with attached or integrated thrust bearing can be supplied in a helical or bevel helical gear arrangement. Quiet operation and strong design are key features. Horizontal or vertical mounting position, splash lubrication and cooling coil or injection lubrication are possible options. The modular design of the POSIREX is based on the POSIRED 2 range, plus a selection of available thrust-bearing parts.
Technical Data:
Torque (T2 nominal): 3,000 up to 800,000 Nm
Transmission Ratio: 4 up to 160 iN
Axial force: F = 50 up to 2,000 kN

Double shaft extruder gears have been built by PIV Drives since 1984 for a variety of applications in the plastics and food industries. This product is in operation around the world to the complete satisfaction of our customer base. The gearing is case hardened and ground with a profile correction for optimal load-bearing performance and noise reduction. An extremely quiet gear-train is achieved through a high contact ratio. The axial forces which occur during the extrusion process are safely absorbed through a system of tandem bearings and self-aligning roller thrust bearings.
Technical Data:
Screw centre distance: a = 15 up to 200 mm
Input speed: up to 1,800 rpm
Torque factor: df = 35 Nm/cm3
Power: up to 5,500 kW

Torque range: 2,600 to 552,000 Nm divided in 26 sizes
Ratios: 6.3:1 to 500:1 standard
A wide selection of ratios is possible through modular Paramax wheel set stages and combination with Cyclo drives
Housing: Standard = grey cast iron, nodular cast iron or steel (optional)
Attachment: Horizontal, vertical or wall fitment
Direct motor mount: Standard (for bevel gear), no coupling alignment required, compact design
Output shaft: Solid or hollow shaft (with shrink disc or key)
Thermal performance: In line with the ambient conditions, the thermal performance can be adapted to the requirement by means of fans and external cooling systems.
Product description
Paramax® helical and bevel gears of the standard Paramax range and the various special Paramax versions are the outcome of six decades of experience in drive engineering. By virtue of the modular design, they permit use under difficult and severe conditions even in the most diverse applications.
The Paramax® product range consists of the standardized 9000 series as well as the special SFC designs for cooling tower drives and compressors and SEC for extruder drives.
With 26 sizes in the Paramax® 9000 series, an application can be precisely designed according to the performance, torque and velocities, thus ensuring a long service life and cost effective, powerful operation.
