“…Comparing to complicated method [7]- [11], this method could avoid complex calculation and exceptional solution, and could almost design any gear or rack. However, this method is also limited in precision, if the image is very small, the size error will arise due to lack of pixels [12]. So, the image must be zoomed in enough.…”

A novel CAD method for tooth profile based on the gearing feature has been proposed in this paper, and this method could be applied to the variable transmission ratio and three-dimension situation. The two pitch curves of the two gears can be generated due to the given transmission ratio. The tooth profile curves are formed in each coordinate system of its pitch curve by the gearing process. Finally, the tooth profile could be extracted and translated into a real dimension by CAD method. It is provided a simply thought for tooth profile design to avoid so much complicated mathematical reasoning.

“…Zhu and Song have a lot of valuable research on geometry design and tooth contact properties of marine crossed-axis beveloid gears [16][17][18]. Meanwhile, Song et al analyzed the meshing characteristics and dynamic response of loaded beveloid gears with small shaft angle by parametric method [19,20], and further on, they investigated the sliding friction effect on the gear dynamics and transmission error (TE) [21]. Trong Phu Do [22] established the elastic models for different types of beveloid gear and simulated contact force and TE in the process of tooth meshing.…”

Beveloid gears are usually employed to transfer motion of small shaft angle, but the assembly errors or misalignment can affect the gear tooth contact and dynamic performance. A dynamic model and tooth contact analysis model of the intersecting beveloid gear pair are established, the defects of the theoretical tooth surface in the meshing are analyzed, and a microgeometry modification method to improve the meshing performance is proposed. At the same time, the effects of system misalignment and manufacturing errors on its meshing characteristics are considered. By studying the sensitivity of the static and dynamic characteristics of beveloid gear on different misalignment components, the influence laws of misalignment on the contact pattern, transmission error, mesh stiffness, and dynamic excitation force are obtained, which give suggestions for tooth surface modification and support structural stiffness design of beveloid gear with a good NVH performance.

“…Marine gearboxes are commonly recognized as the critical subsystems for transmitting power from main engines to terminal drive systems in large ships and vessels (Cooper et al, 1981). In general, the failures of bearings in such gearboxes have significant influences on the gearbox reliability and life span, as bearings are one of the most common and important components in these gearboxes (Song et al, 2015). Therefore, it is of great significance to identify these bearing failures and analyze the intrinsic causes to such failures, particularly for high-power large-scale marine gearboxes.…”

“…In recent years, relatively little literature has addressed the problems of bearing failures within the context of large-scale marine gearboxes, whereas more investigations have focused on the static or dynamic characteristics of the gearboxes, such as shock responses (Wang and Yuan, 2011), modal analysis (Liu et al, 2014), systematic dynamic modeling (Song et al, 2015), topology and structural optimization (Wei et al, 2012).…”

Purpose This paper aims to analyze fatigue failures of a typical marine gearbox under harsh ocean conditions, and these failures are reasonably attributed to the bearing fretting fatigue damages. Design/methodology/approach Two typical FAG cylindrical roller bearings mounted on this marine gearbox are particularly used for analysis, as they are most vulnerable to these failures. A series of simulations have also been conducted to verify the analysis results and failure reasons by reproducing the fretting fatigue damages for the same shaft-bearing system under the same manufacturing error conditions. Findings The analysis results indicate that manufacturing errors are the most possible reasons for the bearing failures, and these errors have more effects on the FAG cylindrical roller bearing as compared to other bearings mounted on the same shaft system. The simulations results are in good agreement with the theoretical analysis results and test results and hence validate that manufacturing errors are the dominant reasons for bearing fretting fatigue damages in this typical marine gearbox. Originality/value Fatigue failures of a typical marine gearbox. Manufacturing errors are the most possible reasons for the bearing failures. A series of simulations have been conducted to verify the analysis results and failure reasons. The simulations results are in good agreement with the theoretical analysis results and test results.
