| Summary: | The load capacity of the rack and pinion mechanism is limited by the contact strength of the gear tooth surface.In order to improve its load capacity,multiple pairs of gears and single rack meshing were adopted.In order to simplify the structure of the transmission system,a single drive multi-point meshing gear rack and pinion transmission mechanism was proposed,which has the characteristics of strong load capacity,small size,light mass and low cost.However,the mechanism has the gear tooth interference problem,and the gear tooth interference amount was studied to solve the problem,and based on the characteristics that the center distance can be changed by gear tooth displacement,the gear tooth interference problem was solved by the modification coefficient compensation method.The rack and pinion mechanism after modification was analyzed by the gear tooth force.The results show that the gear teeth have no interference and the force is uniform.The solution of the gear tooth interference problem greatly improves the load capacity of rack and pinion transmission,so that rack and pinion transmission can be used for heavy-duty conditions. |
