Couplings for PT and motion designs: Technical Summary
Updated May 2015 by Mike Santora || Couplings are devices that connect two shafts for transmission of torque from one to another, usually on rotating equipment such as motors. They should be designed to allow for some end movement. Two types are available — rigid and flexible. Flexible couplings compensate for misalignment, while rigid couplings work […]
Roller chain: Basics and sizing for power-transmission and conveying
Updated February 2018. || Engineers have used chains in motion systems for more than a century. They are versatile and reliable components to drive machinery and convey products. Now, advances in precision and technology let designers use chains in more applications than ever. Remote installations benefit from long-life chain that requires no lubrication, for example. […]
