Flexible Coupling EVOLASTIC

Compact in the axial direction and available in a variety of designs, a flexible coupling widely suitable for motor and engine drive applications.

EVOLASTIC is a highly flexible, backlash-free flexible coupling that allows for the connection of shafts and flanges. The preloaded elastomer absorbs torsional vibrations and shock loads in the drive system. It also efficiently dampens solid-borne sound while simultaneously absorbing misalignments (axial displacement, parallel displacement, angular displacement) that occur between the driving and driven machines. The elastomer, an important component, is shaped into a ring by vulcanizing and bonding rubber and metal. The permissible temperature for natural rubber types (WN, SN, MN) is up to 90°C, while for EPDM types (WE, SE, ME) it is up to 110°C. It is possible to select different rubber hardnesses without changing the size of the coupling. The basic design is broadly categorized into bolt-connected types and plug-in types. Hubs and hubs, or hubs and flanges, can be combined according to the mounting dimensions of the driving and driven machines. This allows for flexible responses to various mounting dimension requirements. *For more details, please download the PDF or feel free to contact us.*

Vibration and shock mitigation using couplings made from rubber and resin.

Solving issues such as vibration, shock, and resonance in rotating machinery. A wide variety of coupling products are available, including those suitable for high temperatures, high-speed rotation, and compliant with ATEX directives.

Our group uses rubber and resin in couplings, which are power transmission components, and proposes solutions to address torque fluctuations, vibrations, and impacts. It has been over 50 years since we created the general-purpose coupling "ROTEX" using polyurethane rubber. Currently, our product range has expanded, and we offer couplings and related components with various functions using rubber and resin materials with different characteristics. 【Examples of Coupling Functions】 ■ Suppressing hunting while maintaining high control in servo drive systems ■ Responding to torque fluctuations in diesel engines and avoiding resonance ■ Absorbing impact torque while withstanding high temperatures of 120°C ■ Reducing noise in hydraulic motor and pump units 【Hydraulic-Related Components】 ■ Potential noise reduction of up to 8 dBA* by using damping rings and damping rods (based on our test results) ■ Contributing to compliance with noise regulation laws *For more details, please refer to the materials. Feel free to contact us with any inquiries.
