“…Although the transmission error is a parameter related to the gearing, it is also affected by adjacent components such as particular shafts, bearings, and housing. In addition, it is influenced by load [1], [2], [3], misalignments [4], [5], different types of tooth damage [6], [7], [8], and micro-geometry in the form of intended modifications [4], [9], [10] and unwanted machining errors [4], [11].…”

“…Fraňová et al [13] used the same approach to obtain STE of spiral bevel gears with various parameters of the tip relief modification. In addition to the modifications, Zhao et al [5] explored the effect of angular and axial misalignments and changes in the center distance on STE and TVMS, and noted a significant effect, especially of axial misalignment, on these characteristics. Liu et al [4] proposed a method to determine the TVMS based on the accuracy grade or measured coordinates of the real surface of the tooth flank (spur and helical gear).…”

Transmission error (TE) is a significant parameter related to gears vibration widely investigated by many authors using different approaches. However, in previous studies, spur and helical gears were mainly examined. There is a lack of studies addressed to double helical and herringbone gears and a comparison among several types of gearing with parallel axes. In this paper, spur, helical, double helical, and herringbone gears are analyzed in terms of static transmission error (STE), contact pressure and tooth root stress. Static contact analyses were conducted using the finite element method (FEM) which is often considered a tool for validating other methods and approaches. Moreover, three variants of boundary conditions of each gear type are introduced, including flexible shafts and the effect of a tip relief modification at sole gears, without shafts, was analyzed. In addition, a concept of a compact test rig intended for STE measurements at low loads was presented. The results have shown, among other things, significant influence of the shaft stiffness and boundary conditions on meshing characteristics.
