Problems solved by technology

One of the main contents of the design of the involute cylindrical helical gear is the mechanical strength check calculation. The traditional check calculation can only grasp the safety factor of the gear macroscopically, and it is difficult to grasp the stress distribution characteristics and changing laws of the gear teeth, and the check workload is extremely high. Large, often repetitive work, time-consuming and labor-intensive, resulting in a great waste of labor costs

Abstract

The invention discloses an involute cylindrical spiral gear mechanism parameterization analysis method and relates to the technical field of gear drive design and analysis. The method is characterized by comprising the following steps that 1, parameters are extracted, wherein all the parameters influencing work of an involute cylindrical spiral gear mechanism are analyzed comprehensively, integrated and classified, gear geometry parameters, material characteristic parameters, load features and finite element model parameters are extracted according to the classes, and the parameters are compiled according to a list form; 2, a parameterized gear three-dimensional model is set up in UG software; 3, preprocessing is carried out in ANSYS software; 4, solving and calculating are carried out in the ANSYS software, wherein the ANSYS software enters a solving module for assigning an analysis type to be static analysis, total solving time is set to be one, the number of solving steps is set to be 100, a PCG is adopted as a solver, and after solving is completed, the ANSYS software quits the solving module; 5, the calculation result is analyzed to judge whether new analysis and calculation need to be carried out or not after the parameters are modified.

Description

technical field [0001] The invention relates to the technical field of gear transmission design analysis, in particular to a parametric analysis method for an involute cylindrical helical gear mechanism. Background technique [0002] Involute cylindrical helical gear transmission is one of the most common forms of mechanical transmission. It can transmit motion and power between two parallel shafts. It has the advantages of good meshing, stable transmission, large coincidence and large transmission torque. One of the main contents of the design of the involute cylindrical helical gear is the mechanical strength check calculation. The traditional check calculation can only grasp the safety factor of the gear macroscopically, and it is difficult to grasp the stress distribution characteristics and changing laws of the gear teeth, and the check workload is extremely high. Large, often repetitive work is time-consuming and labor-intensive, causing a great waste of labor costs. ...
