YDK Series
Gear Coupling
The YDK Series Gear Couplings, developed for maximum performance in heavy-duty applications, provide a reliable solution for power transmission systems with their high torque capacity, compact design, and superior durability characteristics.
Specifications and Advantages
- Compensates for angular misalignments by maintaining optimal tooth contact due to the crowned tooth profile.
- Minimizes stress concentrations, resulting in longer tooth and service life.
- Provides superior wear resistance through high-strength quenched and tempered (Q&T) alloy steel and nitriding heat treatment.
- Offers reliable lubrication performance under high torque conditions with high-performance synthetic grease (down to -40°C).
- Ensures safe and stable power transmission under shock loads, impact operations, and harsh working conditions.
- Features a durable structure specially designed for heavy-duty and high-load applications.
- Provides high power density and space savings thanks to its compact design.
- Offers higher torque transmission capacity compared to elastic couplings.
