“…Liu et al [26] introduced the elastic deformation of the rotor into the multi-DOF dynamic model of ACBBs and studied the influence of rotor deformation on bearing vibration. Ma et al [27] developed a multi-DOF model to study the dynamic contact behavior of four-point contact ball bearings. Based on a multi-DOF tribo-dynamic model, Wen et al [28] revealed the influencing mechanism of starved lubrication on the tribological characteristics of ACBBs.…”

The traction behavior in cryogenic solid-lubricated ball bearings (CSLBBs) of liquid rocket engines (LREs) has a significant effect on the dynamic response of the bearing–rotor system. To reveal the fault mechanism of CSLBBs, a tribo-dynamic model is proposed in this paper that considers the solid-lubricated traction, six-DOF motion of the ball and contact collisions between the ball and the cage. The modified traction model uses fan-shaped and arched sections to discretize the contact area to eliminate the meshing error. The newly developed fault model, called ‘geometrical-frictional defects’, can more realistically represent solid-lubrication coating defects. The results show that the frictional excitation can significantly increase bearing vibration by increasing the traction force on the raceway. The change in the amplitude of the bearing vibration and its derivative can be used as a reference to determine the depth of defects. The width of the defect can be diagnosed by monitoring the double-pulse time interval and spectrum of the bearing vibration signal. This research may provide some theoretical guidance for the design and condition monitoring of CSLBBs.

“…Tsai [14] focused on designing the machine-tool settings for a four-axis milling machine tool for spiral bevel gears to improve contact performances using a predesigned motion curve. Ma [15] developed a nonlinear dynamic model to optimize operation performances of four-point contact ball bearings in a three-point contact state considering lubrication traction and dynamic characteristics of the bearing assemblies. Xiang [16] conducted an analysis of geometric errors of a spiral bevel gear pair in motion axes and their impacts on gear meshing performances.…”

This paper presents an ultimate motion methodology of a face-milling spiral bevel gear pair to synthesize the mating tooth surfaces with a predesigned fourth-order motion curve. The methodology is to control some contact points along the contact path in the process of tooth contact analysis via application of an extended local synthesis which permits some transmission errors rather than zero at the concerned contact point. The modified offset motion correction is selected to demonstrate the proposed methodology. Applied torque corresponding to an elastic approach of 0.00635 mm at the mean contact point is calculated and the loaded tooth contact analysis is performed. Numerical results show that the extended local synthesis can effectively control the transmission errors on the predesigned fourth-order motion curve at arbitrarily predesigned contact points along the contact path of the spiral bevel gear pair. The tooth contact pattern for the actual tooth pair is scattered into three segments since the rotational motion of the driven gear at any instant angular position is dependent on the tooth pair with the least transmission error among the three adjacent tooth pairs. The actual tooth contact patterns of the spiral bevel gear pair become continuous when meshing tooth surfaces are elastically deformed.
