PIV® Twin Screw Extruder Drives Positwin Series

Product catalog summary

Product Overview: The document is a product catalog for Postwin gearboxes, specifically designed for continuous operation in the plastic and rubber industries. These modular gearboxes offer a wide range of center distances, ensuring high performance in demanding applications.

PIV® Twin Screw Extruder Drives - Positwin Series: The Positwin series provides torques ranging from 40 Nm to 35,000 Nm. It includes two types of gear units for dual-shaft co-rotating extruders: gear units for lateral feeding (side feeder) and heavy-duty extruders (compounders). Detailed data for side feeder gear units are available upon request.

Design and Construction: Since 1984, PIV Drives has been manufacturing twin-shaft extruder drives for various industries. The gear units are designed for high reliability, featuring case-hardened and ground gear teeth optimized for bending and torsional loads. The robust design includes a thick-walled grey cast iron housing with a ribbed interior.

Performance and Adaptability: The gear units feature an integrated lubrication and cooling system. They accommodate extruder screw axle bases from 15 mm to 200 mm, with screw speeds up to 1200 min-1 and a torque factor over df = 35. Adaptability to motor speeds is achieved with single- or two-stage gear units from PIV's standard reducer program.

Quality Assurance: All POSITWIN GL extruder drive parts undergo rigorous testing to ensure high quality standards. Gear units for lateral dosing are simpler and do not contain integrated gear transmission steps, with various flanged reduction gears and drive motors available.

Specifications: The document outlines specifications of gear reducers for extruders, emphasizing high-quality standards through rigorous testing. The reducers handle axial forces safely using tandem and self-aligning bearings. The casing is robust, made of reinforced cast iron with internal ribs to prevent deformation. A compact design allows for high mechanical capacity in a small space, with integrated lubrication and cooling systems.

Procedures: Each reducer undergoes bench testing to ensure consistent quality. The reducers are adaptable to motor rotation through standardized stages, integrated into the extruder reducers.

Standards and Recommendations: The reducers are available with worm screw center distances ranging from 15 to 200 mm, with torque and rotation specifications adjustable to process needs. High-performance extruder reducers and simpler lateral dosing reducers are distinguished, with various pre-switchable reducers available.

Key Data from Tables: The tables provide detailed technical data, including dimensions, torque, speed, and axial force specifications for various reducer models. The data highlights the adaptability of the reducers to different operational requirements.

Critical Information: Key parameters include the torque factor, axial force capacity, and bearing life duration. The document emphasizes the importance of customized dimensioning for precise application needs.

Additional Notes: PIV Drives has been supplying these reducers since 1984, focusing on operational safety and optimized gear profiles. The document includes a disclaimer about the proprietary nature of the content and the possibility of technical modifications without notice.
