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

The new series of helical gear units has been studied and designed specifically for use on systems for the SINGLE-SCREW EXTRUSION of various materials, such plastic, rubber, etc.
Our range includes two-stage reduction units, PBE series, with a nominal reduction ratio ranging between 6.3 and 28, and three-stage reduction units, PCE series, with a nominal ratio ranging between 8 and 125.
By being able to have the same reduction ratios 8÷28 on both series either solution can be chosen for the same application, depending on the dimensions and version required.
For all sizes, the housings of the gear units are built in G25 grey cast iron, suitably dimensioned for heavy duty work. They are suitable for mounting both horizontally and vertically.
The output flange, housing the thrust bearing and used for mounting the extrusion screw, is integrated in the housing cast.
The thrust bearing fitted on the low-speed shaft is the 294__E type and dimensioned for heavy duty working conditions.
In the standard version, screw keying is done with a feather key but it may also be done with a grooved profile, according to the most common standards in force.

Brevini's range of mixer drives are planetary gear units modified to meet the operating requirements of water conditioners and of mixers in chemical, ceramic and paper producing industries. The mixer drives combine the traditional advantages of Brevini's planetary technology - compactness and high efficiency - with the characteristics of strength and reliability.
The flexibility of the mixer drive design provides users with a number of construction options, including in-line and right-angle configurations, and the facility to directly mount a motor to the gearbox via a flange. Alternatively, a male input shaft configuration may be used with connection effected by a flexible coupling or pulley. |
|
| Gearboxes complete with reinforced output supports, integral pinion, static negative disc brake and input coupling for hydraulic motors; nominal output torques range from 4.100 Nm to 60.000 Nm. |

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 easy maintenance.
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. |

| The new range of Track drives developped by Dinamic Oil is called EH and has a range starting form 50.000 Nm up to 330.000 Nm |
