Abstract: A theoretical method is proposed in this paper to calculate the unit curve of gear integrated error (GIE). The calculated GIE unit curve includes the quasistatic transmission error (TE) curves of the approach stage, the ...

Abstract: The gear drive is theoretically a normal-order meshing process to transmit movement and power. When temperature variation, misalignment, manufacture error, or deformation occurs, the normal-order meshing will be destroyed. ...

Abstract: Global warming is expected to enhance the global hydrological cycle, leading dry regions to become drier and wet regions to become wetter (the DDWW paradigm). However, this hypothesis has been challenged by both observational ...

Abstract: Preload, which is widely applied in linear motion ball guide (LMBG) to eliminate clearance and increase stiffness, gradually decreases owing to wear, resulting in the degradation of the load-bearing capability and dynamic ...
