Description

Sectionally supported roller core

Technical field

The utility model relates to a kind of sectionally supported roller core of using on a kind of backing roller core, particularly milling train, can realize the self-lubricating between roller core and the bearing, improves the operating efficiency of bundle machine roller system.

Background technology

In the manufacturing of band mill, using, usually adopt backing cloth bearing roller that middle backing roll is supported, existing backing cloth bearing roller is to adopt an axis, and segmentation thereon is fixed with bearing, the roller base direction of bearing is embedded in the groove of saddle seat of convex-concave, with saddle seat fixed support.

In the prior art, in addition an original axis branch is cut into multistage, one bearing is installed on every section axle, the roller base direction of this bearing is embedded in the groove of saddle seat of convex-concave, with saddle seat fixed support, this bearing roll with sectional back lining, have easy for installation, use flexibly, be convenient to change the characteristics of high efficiency.

Existing backing cloth bearing roller, no matter adopting whole axis still is the segmentation axle, because there is frictional force in the surface in roller core and the mutual rotation process of bearing, so reduced operating efficiency of pricking machine roller system and the service life that has reduced backing cloth bearing roller.

The utility model content

The purpose of this utility model is can't realize the defective that self-lubricating, operating efficiency are not high at there being friction between above-mentioned existing back lining bearing roller bearing and the roller core, a kind of sectionally supported roller core of band mill is provided.

To achieve these goals, the utility model provides a kind of sectionally supported roller core, and the roller core segmented connects, at described segmented roll mandrel to running through an oil leab.

Technique scheme central roll wicking surface can be provided with one or more oil outlets, oil outlet and oil leab connect, oil outlet is arranged on segmentation roller core and the bearing contact position, greasing substance in the oil leab is discharged to the position that roller core and bearing are in contact with one another by oil outlet, realizes lubricating of roller core and bearing.

In the technique scheme, also can oil gas separator be set at the oil outlet place, oil gas separator is provided with micropore, can feed mist of oil in the oil leab, be arranged on the micropore on the oil gas separator, mist of oil is separated, lubricating oil is retained at bearing and roller core surface, gas is then discharged from oil gas separator.

As shown from the above technical solution, the segmented roll in-core is established oil leab, and the surface sets out oilhole, by the lubricated friction that can reduce roller core and bearing, has prolonged the service life of backing roller.Oil gas separator separates mist of oil, and the utility model has been realized the self-lubricating between roller core and the bearing, reduces friction, and has improved the service life of operating efficiency and roller system.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment

Fig. 1 establishes the external structure schematic diagram of oil leab for the utility model sectionally supported roller in-core.Fig. 2 establishes vertical schematic diagram of an oil leab and an oil outlet in being, Fig. 3 is the radial section schematic diagram of Fig. 2.As shown in Figure 2, described segmentation roller core 1 axially runs through an oil leab 2, and roller core radially has an oil outlet 3 from the outside surface distributed of grease channel.The utility model is by establishing oil leab 2 with the segmented roll in-core, and the surface sets out oilhole 3, by the lubricated friction that can reduce roller core and bearing, has realized self-lubricating, has prolonged the service life of backing roller, has effectively improved operating efficiency.

Fig. 4 is the inner sectionally supported roller core longitudinal profile schematic diagram that is provided with 4 oil outlets, and Fig. 5 is the radial section schematic diagram of Fig. 4, and Fig. 6 is Fig. 4 external structure schematic diagram.As Fig. 4 and shown in Figure 5, described segmentation roller core 1 axially runs through an oil leab 2, and roller core radially has 3,4 oil outlets 3 of 4 oil outlets can angled even distribution from oil leab 2 outside surface distributed.4 oil outlets are arranged on and the contacted position of bearing, but oil leab injection lubricating oil, also but injection can be played lubricated material, such as mist of oil, the greasing substance that comes out from oil outlet flows to and the bearing contact position, plays the effect of lubricated roller core and bearing, when work, can reduce the friction between roller core and the bearing, improve operating efficiency.

Fig. 7 is the reeded outside schematic diagram of oil outlet.Can dig an oil outlet groove 4 at the circumference place that a plurality of oil outlets of sectionally supported roller core outer surface form, a plurality of oil outlet 3 isolated oil bodies are flowed in groove 4, do to make lubricating oil remain in groove like this, be unlikely to separate fast.During work, the relative rotation with roller core of bearing can make greasing substance disengage face very soon, and groove 4 can make greasing substance retain wherein, the effect of playing continuous lubrication and saving greasing substance.

Above-mentioned oil outlet can be a through hole and also can be an inner threaded hole.

Fig. 8 is the first example structure schematic diagram of the utility model oil gas separator.Oil gas separator 5 is located in the oil outlet 3.As shown in Figure 8, described oil gas separator 5 is a column, and between bottom surface, cylinder inside is axially arranged with one or more mist of oil sorting holes 51 on it, and the column surface is a smooth surface.

Fig. 9 is the second example structure schematic diagram of the utility model oil gas separator.Oil gas separator 5 is a column, and between bottom surface, cylinder is axially arranged with one or more mist of oil sorting holes 51 on it; Described oil gas separator 5 column surfaces are provided with screw thread 52, and column one end is provided with a groove, oil gas separator can be screwed onto with the oil outlet 3 that is provided with screw thread by groove.

Injection mist of oil in the oil leab 2, mist of oil flow in the oil gas separator 5 that is provided with micropore, and fog is discharged on mist of oil sorting hole 51 surfaces, and oil can hang on the mist of oil sorting hole 51, reaches the purpose that mist of oil separates.

It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the spirit and scope of technical solutions of the utility model.
