...Chunxing Gu; Jingyi Tu; Di Zhang Misalignment results in uneven force on the contact surface, which not only increases friction loss but also shortens the bearing's service life, especially for water-lubricated bearings. In this study, an advanced approach is investigated to optimize...

...Jiaojiao Ma; Chao Fu; Weidong Zhu; Kuan Lu; Yongfeng Yang Misalignment is common in hydrodynamic journal bearings and the causes of it can be diversified, making the lubrication performance exhibits stochasticity. Lubricant viscosity often heavily depends on temperature, which may vary during...

...Jiajia Lu; Xianying Feng; Zhe Su; Yandong Liu; Dechen Wang This paper proposes a novel dual-drive hydrostatic lead screw system (DDHLS). The design enables a lower feed speed and a better transmission performance than the conventional hydrostatic lead screw (HLS). Considering the nut-misalignment...

...Chunxing Gu; Xianghui Meng; Shuwen Wang; Xiaohong Ding Surface texturing is one effective means to improve bearing performance. Available studies are mainly focused on the perfectly aligned journal bearing with textures. The studies involving the effect of surface texturing on the misaligned...

... loads and life in engineering application. Considering the misalignment due to the deflection of the bearing spindle, the bearing internal loads and deformations under the action of the complicated external space loads are obtained. The bearing fatigue life including the lives of the rollers...

... investigating the effect of wear along with both aligned and misaligned conditions of journal on the performance of a capillary compensated three-lobe three-pocket hybrid journal bearing system for the various offset factors δ = 0.8,1.0, and 1.2. The wear caused on the bearing surface due to the transient...

...Satish C. Sharma; E. Rajasekhar Nicodemus; Nathi Ram The present work aims to analytically study the performance of misaligned four-pocket, membrane compensated, hybrid journal bearing system operating with micropolar lubricant. In the present study, the flow characteristic of the lubricating oil...

...Jun Sun; Mei Deng; Yonghong Fu; Changlin Gui Journal misalignment exists generally in journal bearings. When severe journal misalignment takes place, the minimum film thickness of journal bearings reduces greatly. In this condition, the surface roughness, the oil viscosity-pressure relationship...

...J. Y. Jang; M. M. Khonsari Misalignment affects nearly all the bearing performance parameters including the cavitation, thermal field, leakage flow-rate, and moments. The present paper provides a comprehensive analysis of misaligned journal bearings based on a three-dimensional mass-conservative...

... measurements carried out using an existing test rig and simulation results. In this study, the verified simulation model is employed studying the effect of misalignment of retainer bearings during the rotor drop-down on the retainer bearings. It is concluded in this study that the misalignment of the retainer...
