L'invention se rapporte à une rotule lisse à charge axiale, en particulier à une crapaudine, comprenant un coussinet sphérique supérieur et un coussinet sphérique  The invention relates to a smooth axially loaded ball joint, in particular to a thrust bearing, comprising an upper spherical bearing and a spherical bearing

La surface d'appui pour le coussinet sphérique supérieur est relativement petite, et la capacité de charge du palier est faible. L'objet de l'invention est de mettre au point une rotule lisse à charge axiale ayant une capacité de charge relativement élevée et convenant en particulier pour les  a sliding gland slit on its periphery and having an opening in the polar zone. The bearing surface for the upper spherical bearing is relatively small, and the bearing capacity of the bearing is small. The object of the invention is to develop a smooth axially loaded ball joint having a relatively high load capacity and particularly suitable for

paliers de grande dimension.large bearings.

Ce résultat est atteint selon la présente inven-  This result is achieved according to the present invention.

tion par le fait que la garniture de glissement se compose d'un ou de plusieurs segments sphériques et d'unepastille de glissement prévue dans le plan polaire et sur la face de joint de laquelle viennent s'appliquer les segments sphériques. Grâce à cette conception de la garniture de glissement, les efforts principaux agissent sur la pastille de glissement si bien que les différents segments sont moins chargés et qu'on évite efficacement un risque de rupture. Selon une autre caractéristique de l'invention, la garniture de glissement se compose de plusieurs segments à surfacesde séparation radialesqui sont munis de chanfreins  in that the sliding lining consists of one or more spherical segments and a sliding disk provided in the polar plane and on the seal face of which the spherical segments are applied. With this design of the slip liner, the main forces act on the sliding pad so that the different segments are less loaded and that effectively avoids a risk of rupture. According to another characteristic of the invention, the sliding lining consists of a plurality of segments with radial separation surfaces which are provided with chamfers

La garniture de glissement 2 est constituée par quatre segments sphériques 6 et une pastille 7 qui viennent s'abouter par leurs surfaces de joint 8, 9, 9a. La pastille 7 forme la surface polaire de la garniture de glissement 2 et est fixée par une cheville 10 qui pénètre dans un perçage 11 du coussinet sphérique inférieur 1. La surface de joint 9 de la pastille 7 et les  The clapper-shown in Figures 1 and 2 comprises the lower spherical bearing 1, a sliding lining 2 of a self-lubricating material and the upper spherical bearing 3 which, by a convex surface 4, is applied to the corresponding surfaces 5 of the sliding lining 2. The sliding lining 2 consists of four spherical segments 6 and a pellet 7 which are abutted by their joint surfaces 8, 9, 9a. The pellet 7 forms the polar surface of the slip liner 2 and is fixed by an anchor 10 which penetrates into a bore 11 of the lower spherical bearing 1. The joint surface 9 of the pellet 7 and the

surfaces de joint 9a des segments 6 sont réalisées coniques.  joint surfaces 9a of the segments 6 are made conical.

Les arêtes, tournées du côté du coussinet sphérique supérieur 3, des surfaces de joint 8, 9, 9a, comportent des chanfreins et forment des canaux en forme de rainures 12. La fixation des segments 6 dans l'alésage sphérique 13 du coussinet inférieur 1 s'effectue par collage et par un bord 14 retenu d'une seule pièce (moitié gauche de la figure 1) ou par un  The edges, turned on the side of the upper spherical bearing 3, the joint surfaces 8, 9, 9a, comprise chamfers and form channels in the form of grooves 12.
