Problems solved by technology

[0005] To sum up, most scholars have devoted themselves to the study of TCA models and algorithms with installation misalignment and the influence of installation misalignment on meshing performance, but they have not paid attention to the reverse calculation of the optimal installation misalignment based on the preset tooth surface contact imprint position and transmission error curve. worth the question
The installation position of the gear pair is very important, the theoretical installation adjustment value is determined by the position of the initial contact point on the tooth surface, but the meshing performance of the gear is not optimal when installed under the theoretical installation adjustment value

Embodiment 1

[0052] Get the theoretical installation adjustment value:

[0053] The ideal gear pair installation is to assemble the processed large and small wheels according to the designed shaft angle α and the theoretical installation adjustment values ​​E, P, and G. Among them, E is the adjustment amount of the offset distance of the large wheel, P is the adjustment amount of the installation distance of the small wheel, and G is the adjustment amount of the installation adjustment distance of the large wheel. However, there are installation misalignments Δα, ΔE, ΔP, ΔG in actual assembly, so that the gears are installed under the misaligned installation values ​​of α+Δα, E+ΔE, P+ΔP, G+ΔG.

[0054] In the installation and adjustment of spiral bevel gears, G is usually set to 0, and the gear pair is in a proper installation position by changing the two values ​​of E and P. Under the proper installation position, the large and small wheels rotate around their own axes respectively φ 1 ...

Abstract

The invention discloses a spiral bevel gear contact track and transmission error optimization method based on installation dislocation, and the method comprises the steps: building an equation set through a constraint assembly condition and an initial point transmission ratio, and solving a theoretical installation adjustment value; and introducing gear pair installation dislocation, and establishing a TCA algorithm containing installation dislocation. An objective function is established by taking installation dislocation as a design variable and presetting characteristic parameters of a contact track and a transmission error, and solving is carried out through a nonlinear optimization algorithm. The result shows that the optimized contact track moves towards the small end of the tooth surface, the loaded contact area expands towards the middle of the tooth surface, and the bearing contact performance is improved; the droop deviation value and the fluctuation amplitude of a transmission error curve are reduced, edge contact is avoided, and the dynamic performance is improved.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a method and method for optimizing the contact track and transmission error of a spiral bevel gear based on installation misalignment. Background technique [0002] Spiral bevel gears have large coincidence, strong bearing capacity, and stable transmission, and are widely used in the transmission systems of large ships, precision machinery, and aerospace equipment. Through Tooth Contact Analysis (TCA), key indicators reflecting its meshing performance can be obtained: tooth surface contact impression and transmission error curve. Due to the manufacturing error and thermal error of the tooth surface and bearing, the actual installation position of the spiral bevel gear will deviate from the theoretical installation position, resulting in installation misalignment. The misalignment of the installation will shift the position of the contact imprint and change the symmetry and f...
