Abstract

Une boîte de palier pourvue de rebords comprend un boîtier (11), (12) ou (13) de forme courte cylindrique permettant d'engager et de maintenir un palier, une base (20), (22) ou (25) pourvue d'une ouverture (40), (42) ou (43) pour engager le boîtier, ou une rainure et un trou de boulon de serrage (5), de sorte que le boîtier s'engage ou est placé et soudé intégralement dans l'ouverture ou la rainure comme sur un coussin. Etant donné que cette boîte de palier peut être obtenue en découpant une ébauche telle qu'une conduite en acier ou analogue selon une taille prédéterminée pour obtenir le boîtier, la base peut être produite par un procédé simple tel que le poinçonnage ou l'emboutissage d'une plaque d'acier, et la section contenant le palier et la surface de fond peuvent être usinées mécaniquement selon les besoins après que le boîtier et la base sont soudés ensemble de manière solidaire, la pièce fixe d'engagement et la hauteur centrale du palier peuvent être maintenues avec précision, ce qui permet d'obtenir une excellente précision dimensionnelle du produit. En outre, étant donné que le boîtier et la base peuvent être reliés par soudage, ce palier peut présenter un degré de rigidité élevé équivalent à une boîte de boîtier conventionnelle en fonte, et présenter également une excellente résistance à l'impact.
