Title
(EN) SWING BARREL TYPE POSITIVE DISPLACEMENT PUMP USING CROSS SHAFT JOINT BEARING

Abstract
(EN)
A swing barrel type positive displacement pump using a cross shaft joint bearing includes a main shaft (1) for connecting with a motor. The upper part of the main shaft (1) is slantwise provided with a rotating barrel (2) which swings along with the rotation of the main shaft (1). The periphery of the rotating barrel (2) is evenly provided with more than three pin shafts (3). Each pin shaft (3) is sleeved with a cross shaft joint bearing (4). Each cross shaft joint bearing (4) includes a bearing (41) sleeved on the pin shaft (3). The outer ring of each bearing (41) is fixedly connected with a swing sleeve (42). Fixed shafts (421, 421')with the same axis extend along the left and right sides of the swing sleeve (42), respectively. The fixed shafts (421,421') are sleeved with a left and right bearing (43, 43'), respectively. The outer rings of the left and right bearings are fixedly connected with left and right cross shaft swing sleeves (44,44'), respectively. The top ends of the left and right cross shaft swing sleeves (44,44') are fixedly connected with each other. The bottom ends of the left and right cross shaft swing sleeves (44,44') are fixedly connected with a connecting bar (5) which is hinged with a piston in a displacement chamber. The positive displacement pump has low wear, low energy consumption, sensitive rotation, high rotation speed, and long service life
(FR)
L'invention concerne une pompe volumétrique dotée d'un palier à rotule transversal, comprenant un arbre principal (1) relié à un moteur. La partie supérieure de l'arbre principal (1) est pourvue d'un cylindre rotatif (2) placé en biais, qui oscille avec la rotation de l'arbre principal (1). La périphérie du cylindre rotatif (2) comporte plus de trois axes de montage (3) répartis régulièrement. Chaque axe de montage (3) est entouré d'un palier à rotule transversal. Chaque palier à rotule transversal (4) comprend un palier (41) enfilé sur l'axe de montage (3). La bague extérieure de chaque palier (41) est assemblée de manière fixe à un manchon oscillant (42). Des axes fixes (421, 421') de même axe s'étendent respectivement sur la gauche et la droite du manchon oscillant (42). Les axes fixes (421,421') sont entourés respectivement d'un palier droit et d'un palier gauche (43, 43'). Les bagues externes du palier droit et du palier gauche sont reliées de manière fixe aux manchons oscillants (44, 44') transversaux gauche et droit, respectivement. Les extrémités supérieures des manchons oscillants (44, 44') transversaux sont reliées de manière fixe l'une à l'autre. Les extrémités inférieures des manchons oscillants transversaux (44, 44') sont reliées de manière fixe à une barre de liaison (5) reliée de manière articulée à un piston dans une chambre de refoulement. Cette pompe volumétrique présente une usure réduite, une faible consommation d'énergie, une rotation sensible, une vitesse de rotation élevée et une longue durée de vie utile.
