“…Ding et al 12 combined the nonlinear dynamic model with the wear model considering tooth backlash and time varying meshing stiffness, put forward the dynamic wear prediction method of gear, and clarified the two-way coupling relationship between tooth surface wear and dynamic response. Considering the influence of wear process on gear meshing stiffness, Chen et al 13 proposed a modified meshing stiffness model and found that gear wear can significantly reduce meshing stiffness. Liu et al 14 proposed a gear dynamic wear prediction method by combining nonlinear dynamic model with quasi-static wear model, and studied the coupling effect between surface wear and dynamic behavior in spur gear system.…”

The centering error is a unique error in the manufacturing process of herringbone gear. The relationship between centering error and tooth wear and the influence of centering error on the service performance of herringbone gear are rarely reported. In this paper, a wear prediction method of herringbone gear with centering error is proposed by comprehensively considering the coupling relationship between tooth wear evolution and centering error. Based on the mixed elastohydrodynamic lubrication theory and Hertz contact theory, the calculation equation of asperity contact pressure of tooth surface after tooth wear is derived and the influence of centering error on load shared by both sides of herringbone gear is analyzed, then the coupling relationship between tooth wear depth and contact pressure is studied. The distribution of contact temperature, asperity contact pressure and wear depth on tooth surface is obtained, and the effect of centering error on them is discussed, then the effects of roughness, input torque and rotation speed on wear of herringbone gear with centering error is analyzed. The results show that the contact temperature, asperity contact pressure, sliding distance and tooth surface wear depth on the advanced contact side of herringbone gear is greater than those of the delayed contact side due to the influence of centering error. And the wear depth of both sides is not uniformly distributed along the tooth width direction and the maximum wear depth is located in the initial meshing area and decreases nonlinearly along the line of action. Besides, the greater the roughness and input torque, the greater the difference between the wear depth on both sides, and with the increase of rotation speed, the wear depth decreases. The results also show that the wear depth can change the centering error, which changed the contact characteristics and load shared by both sides of the herringbone gear. The wear depth and centering error have a significant impact on the meshing and contact performance of herringbone gears, and their influence cannot be ignored in the study of herringbone gears. The results of this paper can provide theoretical support for wear resistance design of herringbone gear.

Gearbox is commonly regarded as the most important power section of wind turbines which has been widely valued for its high malfunction rate. Gear fault researches mainly include wearing, pitting, spalling, breakage, falling off, etc, while little attention was paid to tooth Flank Pitch Error(FPE). Taking a single-stage parallel shaft spur gear as the research object, an 8-DOF gear transmission model and the FPE model were established in this paper and the gear’s time-varying meshing stiffness (TVMS) models with & without tooth FPE were obtained respectively, which the dynamic models with various tooth FPE values under different rotating speeds were simulated after. The simulation results showed that the TVMS mathematical model proposed in the paper under tooth FPE is practical at both low and high rotating speeds. Under the FPE model, side-bands are formed around each multiple of meshing frequency whose peaks are distributed by a fixed fault characteristic frequency ffp interval. The gearbox vibrates severely as the tooth FPE values and rotational speed grow. The peak value of the vibration signal is about 3 times that in case of fault-free state when the FPE value reaches 0.001rad, thus the impact of FPE on gearboxes cannot be neglected.

“…Plenty of wear methodologies and theories are introduced into TFW study, in which the most popular is Archard wear theory. Chen W [8]and Zhang J [9] proposed a modified analytical time-varying mesh stiffness (TVMS) model considering the worn tooth profile and Feng K [10] represented the deviation of the profile from an ideal involute curve and obtained the wear coefficient by comparing experimental and simulation data. Wu S [11] applied the cantilever beam theory to study gear's time varying meshing stiffness by consideration of bending, shearing, compressing and contacting deformation and Feng S [12] developed it by introducing the Timoshenko beam theory which additionally takes fillet-foundation deformation into account, but the results of the theories mentioned are similar.…”

“…At the same time, the fixed volume of the surface material will be exposed to repeated action of alternating stress, resulting in fatigue cracks in the microscopic volume, and finally cracks evolve into wear debris and fall off. The wear capacity Q is proportional to the normal load, inversely proportional to the hardness of the material, and proportional to the sliding distance according to Archard wear theory [8,20]. Although wear will lead to increased flank clearance, it is distinct from excessive flank clearance fault where a constant normal clearance value exists along the whole meshing surface.…”

Tooth surface wear is one of the most common faults of gearboxes which increases the fatigue load on the gearbox and endangers its stable output characteristics and service life. Gear meshing characteristics vary significantly with the wear location and severity. Thus, the wear fault model considering tooth profile deviation, friction and time varying mesh stiffness (TVMS) was established in order to quantitatively study the vibration characteristics of tooth fatigue wear (TFW). Tooth profile modification and friction coefficient coupling were applied to characterize TFW, and the maximum wear depth was introduced to characterize TFW severity. The gear-pair simulation models under multiple wear severities were established and imported to a single-stage parallel gearbox whose dynamic differential equation was established under multiple torque conditions. The dynamic simulation results showed good agreement with the experimental data, which validated the method’s effectiveness. The vibration characteristics under different wear severities and simulation conditions were then obtained and compared.
