Which Drive System is Best for Your Application - It Depends
A common question that arises when designing an application involving power transmission is, “how will this system transfer motion?” Two of the most popular answers to this question are: a Gear Drive System or a Belt and Pulley Drive System. Here at SDP/SI our application engineers are asked “which is better?” And just as with everything else in engineering, It Depends. In this whitepaper we explore both options, the advantages, disadvantages, and circumstances that are better for one over the other. Get the information you need and start designing!
