Research on the load carrying capacity of inclined double-roller enveloping hourglass worm gears
摘要
Abstract
To evaluate the load carrying capacity of inclined double-roller enveloping hourglass worm gears,analytical models for solving the load sharing among teeth and the load distribution along the contact line were presented.According to the characteristic of the inclined double-roller enveloping hourglass worm gears,a load calculation model was established based on some reasonable assumptions.Based on the work mentioned above,the calculation formula for load sharing among the meshing pairs was given.The calculation model for load distribution of the contact line was established based on the Boussinesq' s formula and the finite-difference method.The influencing factors such as installed offset of roller,roller radius and inclined angle of load carrying capacity were analyzed based on the numerical simulation.The results show that the curve of the load sharing among the meshing pairs is a parabola from the starting point to the end point,and the load distribution along the contact line shows the tendency to decrease from root to top of the tooth.Finally,the installed offset of roller,the roller radius and the inclined angle should be controlled into the intervals of 5 to 8 cm,7 to 9 cm and 8° to 12°,respectively,in order to effectively maintain the load carrying capacity of the inclined double-roller enveloping hourglass worm gears.关键词
