By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Current study results on Robotics have been published. According to news reporting from Chongqing, People's Republic o f China, by NewsRx journalists, research stated, "As a critical component of the joint gearbox, spur gear pairs play a crucial role in energy conversion, limiti ng the performance of a collaborative robot. Accurately assessing their instanta neous efficiency and torque fluctuation is essential for developing high-precisi on robot joint control models." Financial support for this research came from National Natural Science Foundatio n of China (NSFC). The news correspondents obtained a quote from the research from Chongqing Univer sity, "This study proposes a computational model to predict the instantaneous ef ficiency and torque fluctuation of spur gears under typical operating conditions . The model incorporates a torque balance model, a load distribution model, and a friction model to reflect the relationship between gear meshing position and e fficiency. The instantaneous efficiency and torque fluctuation of gear pairs wer e compared with the Coulomb friction model with an average friction coefficient and the elastohydrodynamic lubrication model with a time-varying friction coeffi cient. The effect of gear contact ratio on efficiency is analysed, while the ins tantaneous efficiency and torque fluctuation of gears are studied under varying operating conditions. The results indicate a maximum efficiency difference of 1. 86 % between the two friction coefficient models. Under specific o perating conditions, the instantaneous efficiency variation of the gear pair can reach 3.34 %, and the torque fluctuation can reach 5.19 Nm."
