Detailed Description
The invention is described in detail below with reference to the attached drawing figures:
As shown in fig. 1 to 5, the bearing for a jacquard machine of the present embodiment includes: the outer support, a plurality of balls 1, dabber 2, first apron 3 and second apron 4, wherein, each ball 1 inlays and locates between outer support and the dabber 2, and each ball 1 rotationally sets up between outer support and dabber 2, and first apron 3 and second apron 4 cooperation centre gripping outer support and dabber 2, and first apron 3 and second apron 4 cooperation carry out the axial spacing to the outer support, and the outer support uses dabber 2 as the rotatable setting of axle.
The outer bracket comprises an outer ring 5 and a retainer 6, wherein the outer ring 5 is a first circular ring, and the retainer 6 is embedded in the inner circle of the first circular ring. The outer circumference of first ring set up first recess 7, first recess 7 can hold the line of jacquard machine, the interior circle of first ring sets up second recess 8, second recess 8 can hold holder 6, the both ends face of first ring sets up the plane respectively, two planes of first apron 3 and second apron 4 centre gripping. The two end faces of the first circular ring are respectively provided with a concave 15, and the first cover plate 3 and the second cover plate 4 are respectively and radially extended to the two concave 15 positions, so that the axial limiting of the first circular ring is realized.
As shown in fig. 6, the retainer 6 is a second ring, a portion of the second ring is embedded in the outer ring 5, and a plurality of first arc-shaped grooves 9 are uniformly formed in an inner circle of the second ring, and each first arc-shaped groove 9 can accommodate one ball 1. The outer circumference of the second circular ring is provided with a plurality of second arc-shaped grooves 10, the second arc-shaped grooves 10 are used for clamping the retainer 6 and the outer ring 5, relative rotation between the retainer 6 and the outer ring 5 is limited, and the retainer 6 can be provided with protrusions suitable for the second arc-shaped grooves 10. The retainer 6 and the outer ring 5 are manufactured by insert injection molding.
