Study on the Drive Characteristic of Roller Chain of the Large Stroke Manipulator System by Hu Yan

“…In order to solve the current problem of the transmission manipulator design of high manufacturing costs and general easy occasions limitations,a new manipulator based on roller chain drive system is presented,and aiming at the roller chain drive system,through the use of multi-body dynamics theory and Lagrangian methods,the transverse vibration modal characteristics and stability of manipulator system roller chain drive is analyzed and got.The results show that,by comparing the operation characteristics of the large stroke with roller chain drive and non-roller chain drive manipulator system,the proposed model has lower manufacturing costs,and the new manipulator system solutions can better solve the limitations of using traditional manipulator problems are generally easy to use the occasion.The manipulator with roller chain drive and non-roller chain drive in the ideal trajectory operating characteristics of small differences,it is meet the general requirements for operation of the manipulator with using less precision.The chain drive transverse vibration natural frequency increase with the decreasing chain length,the drive speed has less affected on transverse vibration,the chain tension on the chain drive transverse vibration shows that the linear relationship between the natural frequency increases as the tension gradually increases.…”

Discussion on Main Influencing Factor of Wear Resistance of Pre-lubricating Roller Chain by Zhaohua Shang, Wenjun Tao, Chengfeng Liu, Hongju Fu, Anlong Zhang

“…The lubrication state has a great influence on the wear resistance of the ordinary industrial roller chain. The main factors affecting the wear resistance of the ordinary pre-lubricating roller chain are summarized starting with the movement characteristics，wear principle and lubrication condition of the roller chain，combining with the wear resistance bench test，customer feedback and personal experience of the chain，and concludes that the meshing impact，vibration，force condition and rotation speed of the chain will affect the storage of grease in the chain，thus affecting the wear resistance of the chain，while the machining precision，surface state and heat treatment process of the chain parts will also affect the wear resistance of the chain.…”

Analysis on Mixed Lubrication Performance of Pin-bush Pairs in Large-sized Marine Chain by Liu Yi, Liu Xiaoling, Liu Guoliang, Li Qun

“…A model of thermal mixed lubrication of the pin-bush pair was established to study the effects of the equivalent curvature radius, the entrainment velocity, the surface roughness, etc. on the mixed lubrication performance of the roller-chain. The results show that when the large-sized roller-chain assembly operates under low-speed and light-load conditions, the pin-bush pair is essentially in a hydrodynamic lubrication state, and thermal effects can be neglected. …”
