The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model being done one specifies.
Like the rolling pressure-bearing device of Fig. 2, form by a positioning pedestal 4 and a scrolling series unit that in a row is positioned on this positioning pedestal 4 to a kind of bottle placer shown in Figure 5.
Positioning pedestal 4 has a U type groove 43 that runs through two ends, offers a series of grooves 61 and 62 that are used for the positioning and rolling unit on the both sides cell wall 41 and 42 of U type groove 43, and correspondence is in groups one by one for groove 61 and 62.
Each rolling unit comprises a limit shaft 1; Limit shaft 1 is a stepped shaft; Comprise thicker interlude 15 and both sides axle head 14 and 16, left axle head 14 forms the shaft shoulder 12 with the radial face that interlude 15 joins, and right axle head 16 forms the shaft shoulder 13 with the radial face that interlude 15 joins; Wherein the length of interlude 15 (being the distance of 13 of the shaft shoulder 12 and the shaft shoulders) just in time equals the groove width of U type groove 43, like this, left axle head 14 and right axle head 16 is being taken respectively when being placed in groove 61 and 62, and whole limit shaft is at the limited chucking of left and right directions (axially).Whole limit shaft 1 is an one with respect to U type groove 43 bridge joints, and the U type slot space of center forms one and cushions and dodge the space.
Be socketed with copper axle sleeve 3 on the limit shaft interlude 15; The external peripheral surface of interlude 15 has the arc-shaped slot 7 of annular; It specifically is opened in interposition; Offer on the axle sleeve 3 and corresponding 8 knock holees 31 that circularize arrangement in the position of arc-shaped slot 7, be seated in 8 balls 2 in the arc-shaped slot 7 through knock hole 31 circumferential spacing and rotatable being arranged between arc-shaped slot 7 and the said knock hole 31, limit shaft interlude 15 connects together with the form and the axle sleeve 3 of free-running fit.Wherein, the quantity of knock hole and ball also can be adjusted according to actual needs.
The outer cover of axle sleeve 3 is provided with steel bushing 5, both interference fit.The outer round surface of steel bushing 5 has just formed the rolling load bearing face of rolling unit.When fix shaft 1 was positioned a pair of groove 61 and 62 together with axle sleeve 3 and steel bushing 5 grades by bridge joint after, the formed rolling unit left and right sides was limited, and fix shaft 1 is fixed, and steel bushing 5 rotates after can acting on ball 2; And when rotating the groove structure of U type groove 43 just in time provide one be convenient to rotate dodge the space, formed each of certain a plurality of rotating units dodged the space and can be connected, also can be independent separately.
As shown in Figure 5; The width of both sides cell wall 612 and 613 from the notch to the bottom land that is arranged at the left groove 61 on the cell wall 41 is preferably consistent with the external diameter of left axle head 14; When left end shaft 14 when being cylindrical, the bottom land 611 of groove 61 can have a cambered surface that matches with its external diameter; Certainly, left end shaft 14 also can be square structure.Cell wall 612 and 613 parallels; The angle on the notch plane of living in (being the upper end of cell wall 41 among Fig. 5) of cell wall 612 and 613 trend and groove 61 is preferably acute angle; For example can be the angle of one 45 degree; Because the locating surface 45 of pedestal 4 is substantially parallel with this notch plane of living among the embodiment; Can remain on the stability of being convenient to keep each rolling unit when this rolling pressure-bearing device is endways to be used (purpose is for the gravity direction of whole fix shaft and appurtenances thereof in use is towards the bottom of groove 61 basically, and then helps whole fix shaft and appurtenances are stabilized in the groove 61) like this.Left-hand end 14 direction of arrow B in the figure is located in the groove 61 during use, and then helps through the location of whole limit shaft 1.In like manner, the location of fix shaft 1 opposite side also is similar with cooperating.
In addition, the both sides groove 61 and 62 that is used for positioning limit axle 1 also can be arranged to the form of knock hole.
Because groove 61 and 62 is inclined to set, in the course of the work, slide block on the bottle placer jaw and limit shaft 1 and steel bushing 5 relative motions extruding are sealed brick and are closed.4-5 antifriction-bearing box group arranged below each slide block, can carry the balance of axle pressure and slide block preferably, improve the service life of rolling pressure-bearing device.
Above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineering staff in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
