About this document
Gearbox Torque Calculation with Inertia by atesarik is a document available to read on EtoBox.
This document summarizes methods for calculating different torque components in sucker-rod pumping units, with an emphasis on accounting for inertial effects. There are three main types of torques: 1) rod torque from polished rod loads, 2) counterbalance torque to move counterweights, and 3) inertial torques from accelerating/decelerating unit parts. Counterbalance torque opposes rod torque and varies sinusoidally with crank angle. Inertial torques are difficult to calculate but important for high-slip moto
