Abstract

L'invention concerne une structure de support à paliers multiples dans une imprimante 3D. La structure de support à paliers multiples comprend un engrenage et de multiples paliers permettant de supporter l'engrenage. De multiples paliers sont répartis sur deux côtés de l'engrenage. L'un des multiples paliers est placé sur un côté de l'engrenage, un espace d'extrusion est formé entre le palier et l'engrenage et une première force d'actionnement est appliquée à l'engrenage. Les paliers restants sont répartis sur l'autre côté de l'engrenage, les paliers restants sont tangents par rapport à l'engrenage et des points de tangence sont formés entre ceux-ci, les paliers restants appliquent une seconde force d'actionnement à l'engrenage, les points de tangence sont des points de support de force entre les paliers correspondants et l'engrenage, et la première force d'actionnement et la seconde force d'actionnement sont équilibrées. La structure de support à paliers multiples dans l'imprimante 3D selon la présente invention fournit des forces d'actionnement équilibrées à l'engrenage, et par conséquent la structure de support à palier multiples peut supporter l'engrenage et aider l'engrenage à réaliser une action d'extrusion et peut également empêcher l'engrenage et un moteur correspondant d'être déplacés, ce qui permet d'empêcher un arbre de sortie du moteur d'être déformé et de prolonger la durée de vie du moteur.
