EAS®-smartic®

Product catalog summary
Overview: The document provides technical specifications and installation guidelines for EAS®-smartic® torque limiting clutches, designed for backlash-free torque transmission and overload protection in mechanical systems. It also covers the ROBA®-DS series and includes contact details for global representatives.
Functionality: EAS®-smartic® clutches transmit torque from a drive shaft to a drive element, with types 481, 484, and 486 offering different configurations for connecting shafts and compensating for misalignments. They disengage when the set torque limit is exceeded and automatically re-engage once the overload is resolved, maintaining the same angular position.
Key Features:
  • Backlash-free torque transmission for the clutch's lifetime.
  • Easy installation with a single screw clamping ring hub.
  • Simple torque adjustment using a graduation scale.
  • High transmission security with optional keyway and clamping ring hub.
  • Wide torque range adjustment from 6% to 100% of maximum torque.
Installation: Clutches are secured onto shafts using a clamping ring hub, with an optional keyway for enhanced safety. Drive elements are centered on the ball bearing and secured with a pressure flange. Proper screw quality and tightening torque are essential for secure torque transmission.
Torque Adjustment: Clutches are preset to 80% of maximum torque unless specified otherwise. Adjustments are made by loosening the locking screw, turning the adjusting nut to the desired torque value, and re-securing the locking screw.
Technical Specifications:
  • Various types (481, 484, 486) cater to different shaft configurations and misalignment compensations.
  • Torque ranges from 2.7 Nm to 500 Nm depending on the type and size.
  • Maximum speeds range from 2000 to 3000 rpm.
  • Permitted misalignments and mass moments of inertia are specified for each type.
Design Variants: The document details different design variants, including flange clutches, backlash-free clutches, and torsionally rigid clutches, each with specific applications and configurations.
Specifications: The document outlines different types of clutches and couplings, such as Type 486._25.0, 486._35.0, and 486._45.0, with specific bore sizes and torque capacities. It details the minimum and maximum bore diameters and the corresponding keyway standards according to DIN 6885.
Technical Data: Key technical data includes limit torques for overload, nominal and peak torques, maximum speed, and permitted misalignments for flexible torsionally rigid shaft couplings. The document also specifies mass moments of inertia and weights for different types and sizes.
Installation and Adjustment: Instructions for installing and adjusting contactless limit switches are provided, including technical data for different switch types. The document specifies the construction size, input voltage, and protection features of the switches.
Product Summary: A comprehensive list of products is provided, including safety clutches, shaft couplings, electromagnetic brakes, and DC drives. Each product type is briefly described, highlighting its key features and applications.
Global Representatives: Contact information for representatives in various countries is included, providing phone numbers, fax numbers, and email addresses for customer support and inquiries.
Conclusion: EAS®-smartic® clutches offer reliable and efficient torque transmission solutions with easy installation and adjustment features, suitable for various mechanical applications requiring precise torque control and overload protection.
