Bevel Gear Units
- These bevel gears are characterised by a sturdy, non-torsional
and space-saving housing. Their wheelsets of alloyed case hardening steel
have a Klingelnberg-Cyclo-Palloid gearing and are case hardened and lapped
in pairs.The arrangement of the screw fastening faces enables a wide choice
of fitting positions.On request, contact-less shaft sealing variants as good
as the connection for an oil circulating lubrication may be provided.
Reinforced shafts are also available.Every precision-application in the
sector of printing, paper, textile and tool-machines draw advantages in
using this kind of gears.
Torque (T2 nominal): 30 up to 8,500 Nm
Transmission Ratio: 0.5 up to 5 iN
Single Screw Extruders Drive
- This series of gearboxes with attached or integrated
thrust bearing can be supplied as bevel or helical gear. Quiet operation and
strong design are key features. Mounting position horizontal or vertical,
splash lubrication and cooling coil with or without injection lubrication
are possible options. Their modular design is based on the POSIRED range,
plus appropriate thrust bearing-parts which are readily available.
Torque (T2 nominal) Nm: 3,000 up to 160,000
Transmission Ratio: 4 up to 160 iN
Axial force: F = 50 up to 2,000 kN
Twin Screw Extruder Drives
- Double shaft extruder gears have been built by PIV Drives
since 1984 for a variety of applications in the plastics and food industries
and have been put into operation around the world to our customers' complete
satisfaction. This extremely compact and appealing design means that we are
able to provide a modern, high-power gear in small installation spaces.
The gears are case hardened and ground and optimised with a profile
correction according to the load, which consists of bending and torsion. A
very good noise behaviour is achieved through a high contact ratio.
The axial forces which occur during extrusion from the process part are
safely absorbed in the gear with tandem bearings and self-aligning roller
Screw centre distance: a = 15 up to 200 mm
Input speed up to 1,800 rpm
Torque factor: df = 35 N/mm2
Power: up to 5,500 kW
Injection Moulding Machine Drives
- PIV Drives has developed this range of rack-and-pinion
drives for closing the mould of injection moulding machines. This kind of
drives are quiet running spur gearboxes presenting a compact construction
with an integrated motor.
They have a double toothed rack as output.To achieve high performance it is
important to realise an almost perfect load distribution on the rack: case
hardened and grounded gear wheels are the base for these high performance
drives with highest accelerating and decelerating torque and as very good
Rack clamping force: up to 450 kN
Rack speed > 2,000 mm/s
Large Industrial Planetary Units
- This planetary gear series (5 sizes) is intended for
industrial application in the upper output torque range, up to 1,000,000 Nm.
They are backed by a long experience in the construction of planetary units
for variable speed drives.
Their most important features are:
- Compact design and high power density. The optimisation of the number of
planets for each planet stage leads to an excellent torque / weight ratio.
- The modular structural design of the gear case leads to a universal range
of uses. The majority of designs needed can be covered by standard models:
in line and right angle versions.
- The housings are designed for flange or shaft mounting or foot design
- The output shafts are supplied as male or hollow shafts.
Torque (T2 nominal): 245,000 up to 1,000,000 Nm
Transmission Ratio: 20 up to 2,240 iN
Ultra Compact Shaft-Mounted Gear Units
- POSIPLAN New range of ultra-compact planetary and bevel
helical gearboxes for industrial applications.
These new gear reducers, which are protected by a specific patent, feature a
combination of planetary and helical/bevel helical gears that takes
advantage of the strengths of each technology: compact size, reliability and
This new series of lighter, more compact gear reducers surpass traditional
solutions for planetary and bevel helical gear reducers and also ensure
shorter production times and lower production costs.
The design of these ultra-compact gear units is based upon precise analyses
using FEM (Finite Elements Method) techniques applied to 3D models, which
means that performance, in terms of duration and silence, was optimized
already in the virtual prototype phase.
Advanced engineering techniques, long experience and the use of high quality
parts from Brevini Riduttori and PIV Drives led to the creation of a product
that ensures high performance over time, a fact that has been confirmed by
tests that simulate real operating conditions.
Torque (T2 nominal): 5,000 up to 67,000
Transmission Ratio: up to 2,000 iN
Special Purpose Gear Units

special shifting gears for printing-machines, special drives for
The extensive part-assortment from the standard-program offers many
components, with which can be constructed each customer-specific solution.
Explanation of the illustrated application (picture):For coiling up and
decoiling of plate coils, sturdy special gearboxes are needed, in view to
retain the reaction forces of the coiling process. PIV Drives provides
customised solutions for lower and higher coiling power.
