Abstract

The utility model discloses a slewing bearing for small packaging machinery. The slewing bearing for small packaging machinery comprises an outer ring and an inner ring, wherein the outer ring and the inner ring are respectively provided with a circular roller path; the centers of the circular roller paths of the outer ring and the inner ring do not coincide to form a contact point and a contact angle; steel balls are positioned inside the circular roller paths between the outer ring and the inner ring; the steel balls are in point contact with the two circular roller paths; the inner ring is connected with a plug; and an oil hole communicated with the circular roller paths is formed in the plug transversely. The slewing bearing is low in cost, compact in structure and light in weight, the steel balls are in point contact with the circular roller paths, and certain axial force, radial force and overturning moment can be endured. When the axial force and the overturning moment act simultaneously, the steel balls transfer axial loading through the contact angle, and the oil hole is processed on the plug for facilitating processing and use, so that the problem that the inner circle surface of the inner ring is incapable of oil injection is solved, and the problem that the oil hole cannot be processed on the small slewing bearing is prevented. The small slewing bearing is particularly suitable for slewing devices of small packaging equipment machinery.

Description

Miniature Packing-machine tool pivoting support
Technical field
The utility model relates to the pivoting support that a kind of package packing machine is used.
Background technique
The pivoting support of known mechanical use, complex structure, requiring has enough radial rigidities, and boundary dimension is larger, and metal wastage and manufacture are large, and the manufacturability of structure is complicated, and the inner ring inner headed face can't oiling.Therefore, be not suitable for the Miniature Packing-machine tool.
Summary of the invention
In order to overcome the pivoting support complex structure of known mechanical use, boundary dimension is larger, manufacturability is complicated, and the outer ring periphery can't oiling defective, the utility model provides a kind of Miniature Packing-machine tool pivoting support, and this Miniature Packing-machine tool is simple in structure with pivoting support, and boundary dimension is little, processing technology is simple, and the inner ring inner headed face is easy to oiling.
The technical solution of the utility model is: this Miniature Packing-machine tool comprises outer ring and inner ring with pivoting support, outer ring and inner ring circumference offer vertical mounting hole, outer ring and inner ring are respectively equipped with arc raceway, the arc raceway center of outer ring and inner ring does not overlap, consist of point of contact and wrapping angle, in the arc raceway of steel ball between outer ring and inner ring, steel ball contacts with two sections arc raceway points, inner ring is connected with obstruction, laterally offers the oilhole that communicates with arc raceway on stopping up.
Advantage of the present utility model: cost is low, and compact structure, lightweight, steel ball contact with arc raceway point, can bear certain axial force, radial force and tilting moment.Do simultaneously the used time in axial force and tilting moment, steel ball transmits thrust load by wrapping angle, this product center raceway diameter is little, simultaneously with oil hole processing convenient processing and use on stopping up, solved the problem that the inner ring inner headed face can't oiling, the problem of having avoided to process oil hole on small-sized pivoting support.Be specially adapted to the swivel gear of small package dress plant machinery.
Description of drawings
Fig. 1 is an embodiment's of the present utility model structural representation.
Fig. 2 is obstruction and the oil hole structure schematic diagram in Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 2.
In figure: 1. outer ring, 2. steel ball, 3. inner ring, 4. oilhole, 5. obstruction.
Embodiment
In Fig. 1, Fig. 2 and Fig. 3, this Miniature Packing-machine tool comprises outer ring 1 and inner ring 3 with pivoting support, and outer ring 1 and inner ring 3 circumference offer vertical mounting hole.Outer ring 1 and inner ring 3 are respectively equipped with arc raceway, and the arc raceway center of outer ring 1 and inner ring 3 does not overlap, and consist of point of contact and wrapping angle.In the arc raceway of steel ball 2 between outer ring 1 and inner ring 3, steel ball 2 contacts with two sections arc raceway points.Inner ring 3 is connected with and stops up 5, laterally offers the oilhole 4 that communicates with arc raceway in obstruction 5.
Outer ring 1 and inner ring 3 circumference are offered vertical mounting hole, conveniently are connected with main frame.Steel ball 2 contacts with two sections raceway points, has avoided larger frictional loss.Between steel ball 2 and raceway, wrapping angle 45 0To bear thrust load in order improving, also can to increase wrapping angle.
Oilhole 4 is installed lubricating cup at the inner headed face that stops up 5, and oilhole 4 is to raceway charging-up lubricant oil fat, to keep the lubricated of raceway and roller.The raceway of this kind mode is lubricated solved inner ring inner headed face and end face can't oiling, the problem that can't process of endoporus oilhole.
This pivoting support is without seal arrangement, outer ring 1 and the same height of inner ring 3, and the upper lower plane of outer ring 1 and inner ring 3 keeps same position height simultaneously.
During assembling, integrated type is made in outer ring 1 and inner ring 3, by the filling hole steel ball 2 of packing into.

Claims (1)

1. Miniature Packing-machine tool pivoting support, this Miniature Packing-machine tool comprises outer ring and inner ring with pivoting support, outer ring and inner ring circumference offer vertical mounting hole, outer ring and inner ring are respectively equipped with arc raceway, it is characterized in that: the arc raceway center of outer ring and inner ring does not overlap, consist of point of contact and wrapping angle, in the arc raceway of steel ball between outer ring and inner ring, steel ball contacts with two sections arc raceway points, inner ring is connected with obstruction, laterally offers the oilhole that communicates with arc raceway on stopping up.
