About This Product

■Features of Durimitec's couplings

・Dulimaitec's couplings are used to connect the driven and driving shafts and transmit power. ・You can choose from a variety of shaft fixing methods for Durimaitec's couplings. Durimaitec's coupling material is made of corrosion-resistant, lightweight, and highly rigid aluminum alloy (duralumin), making it possible to construct a rotating system that is lighter and has lower inertia. *DRB, DRBS, DOH, DOHS, DJC, DJCS, DRG, DRGL, etc. However, excluding DRN, DRJ, DRP - Regarding the method of fixing to the shaft: We offer a set screw type and two types of clamp types, so you can choose the most suitable type. Depending on the model, we also offer different types for the input and output shafts, and types that allow you to select and combine different shaft diameters.

■Zero backlash. High response. High damping. Vibration absorption.

・High-gain rubber anti-vibration coupling is a new rubber type coupling that suppresses the resonance that occurs in motors, etc. and shortens stabilization time. ・Productivity due to high gain due to excellent damping performance and rigidity. Contribute to improvement and quality improvement.

■Summary

・The normal/maximum torque of the DHRA type is reduced by applying the following correction coefficient depending on the ambient operating temperature. ・Select based on shaft diameter and common torque. (You can select the model number based on the shaft diameter and common torque.) ・Improved productivity due to high gain and stabilization time

■ Anti-vibration coupling damping performance

Anti-vibration couplings have better damping performance than disc types and have a higher ability to absorb vibrations.

■Phase of Bode diagram

When comparing the gain width (gain margin) with 0db on the same line at the -180° point in the phase of the Bode diagram, anti-vibration coupling can be larger. In other words, by increasing the gain, a larger gain width is obtained.
