The research on the influence of shaft intersection angle error on gear hobbing processing is now realized in combination with the specific gear hob and the basic parameters of gear. Basic parameters of gear hob and gear, pressure angle of gear α= 25 °, because the standard pressure angle...
When no external error is considered in gear hobbing, that is, the center distance installation error of gear hob is zero. If the installation error of gear hob center distance is considered, at this time, the center distance α Installation error e α Not zero. Given the basic parameters...
Based on Mathematica software, draw the right tooth surface of one tooth of spur cylindrical gear, and combine the right tooth surface models of two spur cylindrical gear teeth obtained by simulation, as shown in Figure 1. In Figure 1, the light cyan involute tooth surface is the theoretical...
The new digital simulation method of cylindrical gear hobbing process is proposed, which provides a new way for cylindrical gear hobbing model simulation. It provides a new method for the digital simulation of cylindrical gear hobbing, but due to the author’s limited level and time, this subject still needs...
The new digital simulation method of cylindrical gear hobbing process is proposed. By analyzing the position relationship between the hob and the workpiece, the three-dimensional spatial meshing simulation model of the hob and the cylindrical gear is established, and the angular relationship between the hob and the gear in...
The error caused by the change of radial distance between the gear hob and the axis of the processed cylindrical gear is called radial machining error. The possible factors causing the error are: the radial positioning error of gear blank in gear hobbing, the periodic change of gear blank...
Gear as the core mechanical foundation. Despite the high requirements for the manufacturing and installation accuracy of gears, with the development of industrial modernization and the rapid maturity of gear manufacturing technology, the product quality and machining accuracy of gears are constantly improving. The high requirement of gear manufacturing...
During gear hobbing, the hob axis and gear axis must meet a certain axis intersection angle. The installation axis intersection angle of gear hob refers to the minimum staggered angle between hob axis and gear axis, and the axis intersection angle is recorded as Σ: Where: β 1 –...
