Roller system leave unused, tend to the state of scrapping.In line with the principle repaired the old and utilized scraps, old roll bearing roller is now made into improvement, with up to
The purpose being used interchangeably to new and old roller system.
Utility model content
The defects of the utility model is in order to overcome existing roll to cannot be used for new roller system, there is provided one kind can be new
Roll in old roller system mutually.
The utility model in order to overcome drawbacks described above used by technical scheme be：One kind can mutually be used in new and old roller system
Roll, include the body of roll and roll neck of interconnection, be roller shoulder with the end face of roll neck connecting portion on the body of roll, the periphery set of roll neck
Provided with sealing shroud, sealing shroud is provided with boss, and boss has larger diameter end and smaller diameter end, wherein, the larger diameter end patch of boss
Lean against on roller shoulder, the smaller diameter end of boss is fixed on roll neck, on the side being be arranged in parallel in the larger diameter end of boss with roller shoulder
Provided with annular seal groove, the annular seal plate for substituting closed ring seal groove is arranged with the outer peripheral face of the smaller diameter end of boss.
Preferably, connected between the described body of roll and roll neck for arc transition.Wherein, the center of sealing shroud, which is provided with, is used for admittedly
Mounting hole of the Dingan County on roll neck, and the shape of the outer peripheral face of the shape of mounting hole and roll neck matches.
In the utility model, the central axis of sealing shroud overlaps setting with the central axis of roll neck.
In the utility model, the central axis upright of annular seal plate and sealing shroud is set, and the center of annular seal plate
Axis overlaps setting with the central axis of roll neck.
In the utility model, the external diameter of annular seal plate is more than the external diameter of the larger diameter end of boss, annular seal plate it is outer
Footpath is less than the external diameter of roller shoulder.
Further, the axial spacing of roller shoulder, the axial spacing of the larger diameter end of boss, the axial spacing of annular seal plate
The ratio of three is 85：110：115.
In the utility model, the end of the smaller diameter end of boss is provided with chamfering.
Beneficial effect：The utility model is arranged sealing shroud and ring packing by the roll neck outer peripheral face in existing roll
Plate, reach the purpose for the axial spacing for expanding roller shoulder, sealing shroud and ring can be adjusted according to the installation requirement of new roller system
The axial spacing of shape sealing plate, and then old roll is applied in new roller system；After annular seal plate is removed, roll
It can apply again in old roller system, reduce cost.Wherein, sealing shroud and annular seal plate can also disperse the radial direction and axle of roller system
To stress, the service life of roll is improved.

Embodiment
Technological means, creation characteristic and the purpose reached to realize the utility model readily appreciate, with reference to
Schematic diagram, the utility model is expanded on further, but the utility model scope claimed is not limited to specific embodiment party
Scope described in formula.
A kind of roll that can be in new and old roller system mutually, as shown in figure 1, the body of roll 1 and roll neck 2 including interconnection,
Wherein, the central axis of the body of roll 1 and roll neck 2 overlaps, and is connected between the body of roll 1 and roll neck 2 for arc transition.
With the end face of the connecting portion of roll neck 2 it is roller shoulder 3 on the body of roll 1, the periphery of roll neck 2 is arranged with sealing shroud 4, sealing shroud 4
Central axis overlap setting with the central axis of roll neck 2.The center of sealing shroud 4, which is provided with, to be used to be fixedly mounted on roll neck 2
