Flexible power transmission couplings usually accommodate a specific distance between the shaft ends of the machines they connect. But an expandable coupling lets the distance ...

The spider determines the coupling’s torque rating. It also affects the coupling’s response to vibration, temperature, chemicals, misalignment, and high speed, as well as its ease of installation.

The Ringfeder-Henfel-Henflex HDFB split elastic couplings, available from leading supplier Bearings International (BI), are ideal for the most demanding applications and aggressive environments in ...

Now, MIT researchers have built a new superconducting circuit that could dramatically speed up this process.

The reliable manipulation of the speed at which light travels through objects could have valuable implications for the development of various advanced technologies, including high-speed ...

The flexible pricing mechanism will reportedly be extended to more trains next year, which will better serve the public and improve the efficiency of the high-speed railways nationwide.
