Split elastic couplings for low speed, high torque applications
Fourth Quarter 2019
Shaft power components
The Ringfeder-Henfel-Henflex HDFB split elastic couplings, available from Bearings International (BI), are ideal for the most demanding applications and aggressive environments in mining, ports and steel factories, among others. They are suitable for all low speed, high torque applications where minimal equipment downtime is essential.
Developed under the most modern concepts of application engineering and advanced 3D project and Finite Element Analysis (FEA) techniques, the HDFB split elastic couplings allow efficient torque transmission through the compression of its flexible elements, which also absorb shocks and vibrations from the drive and driven machine, besides compensating angular, radial and axial misalignments.
They can operate within a broad temperature range of -30 to 85°C. Advantages include a long lifespan and simple, fast, low cost maintenance. Due to the simple construction, installation is both fast and safe. The couplings are available in many sizes for applications up to 600 mm, and a torque capacity from 96,7 to 1147,6 Nm. Features include radial mounting and dismounting; on- site maintenance; reduced operating costs; no need for special tools, drive or driven machine displacement; alignment preservation; lubrication-free operation; and interchangeability. This makes it easier for customers already using buffer roller couplings to change over to the new split coupling design with ease. They are interchangeable with most of the traditional elastic couplings on the market. With minor changes, these can replace grid and gear couplings.
