Abstract

The rapidly advancing technological development leads to designing and researching a new multi- output gear mechanism. The investigated new double-output gear mechanism has two output coaxial shafts located against the input shaft on the other side of the gearbox. The gear mechanism achieves high gear ratios. Its limiting structural node is the output stage, to which the gears belong. The problem is addressed through the analysis of the stress resistance of tooth flanks in contact and bending. The content of the paper is a comparison of analytical computations with the modal analysis on the model. We expect that new findings will be beneficial for further optimization of the gear mechanism.

Highlights

  • From continuing trends of current developments, it is believed that in the 21st century, there will be a rise in production to meet higher customer demands for products

  • The limiting output stage is a hollow shaft with an internal gearing at the end that needs an investigation from the strength and dynamics point of view

  • The output stage of the double-output gear mechanism shown in Figure 2 under number II was researched

Summary

Introduction

From continuing trends of current developments, it is believed that in the 21st century, there will be a rise in production to meet higher customer demands for products. It puts a strain on the flexible response to customer requirements, and on the construction machinery of the manufacturing technology that is related to the concept with the required technical parameters. The producer declared a high accuracy of the transfer of their characteristic precision. In this regard, it should be noted that this kind of reducers has a relatively short history of development and implementation. High-precision gears are predestined for applications in machinery and equipment, which require virtually zero clearance, high positioning accuracy and repeatability of accomplishing its high stiffness with the requirement of a higher gear ratio
