Abstract

The utility model discloses a crown roller. The utility model is characterized in that reinforcement rings are arranged at the both ends of the outer casing, the outer casing is sleeved on the roller body, an empty abdominal cavity is arranged between the outer casing and the roller body, a through hole is arranged on the axle head at one end and on the corresponding axle body, and the through hole is connected with the empty abdominal cavity. The utility model can be utilized on various paper manufacturing machines and paper product processing machines, the desired optimal crown degree can be willfully adjusted under the condition that the machine is not stopped, the service life of the selected anti-corrosion and anti-abrasion high intensity metal material or non-metal material is long, and the closedown time and the maintenance cost of the user are greatly reduced.

Description

A kind of crowned roll

(1) technical field: the utility model mainly is applicable to the vitals on paper machine and the paper product processing machine, and a kind of crowned roll of new ideas is provided to paper mill and paper product source mill specifically.

(2) background technology: existing common crowned roll mainly is made up of spindle nose 1, roll body 2, peripheral bag one deck non-metal shell 3 shown in 1.This structure is extremely inconvenient in processing with in using.Because highly must could process in shell dolioform by the extraordinary lathe of special use, this special lathe whole nation is few for number, and skewness, the remote districts that some industry fall behind do not have this lathe, therefore many users are in order to keep in repair or change the middle height of shell, often to transport far special manufacturer and go to require assistance, pretty troublesome and expense is big, have a strong impact on ordinary production.

(3) summary of the invention: the purpose of this utility model is to provide a kind of new ideas crowned roll, and it can regulate the middle height of crowned roll easily arbitrarily.

The technical solution of the utility model is achieved in that a kind of crowned roll, it mainly comprises the spindle nose that is contained in roll body, be provided with thin-wall shell in the roll body periphery, at outer surface of outer cover one deck corrosion-proof wear circle can be set also, it is characterized in that: the two ends at shell are provided with reinforcing ring, outer cover suit leaves chamber on an empty stomach between shell and roll body on roll body.Spindle nose at one end and corresponding roll body are provided with through hole, and this through hole is communicated with the empty stomach chamber.

The utility model compared with prior art has the following advantages:

1, releases one and need not calculate and verify medium-altitude new ideas; by the time when start is formally put into production; by different products; different technological requirements; regulate the pressure size of input media at the scene arbitrarily; just can obtain easily satisfactory in height, make manufactory and user factory cancel the single medium-altitude history of the extraordinary machine tooling of necessary employing, thereby greatly reduce downtime and maintenance cost for user factory.

2, middle height of the present utility model can be regulated under non-stop-machine situation as required, promptly regulates D shown in Fig. 2 and D arbitrarily ₀The difference of diameter.

3, corrosion resistance is strong, and shock-absorbing is good, and the intensity height has prolonged the life-span, has reduced the product cost of user factory, has simplified equipment control.

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the A portion enlarged detail among Fig. 2;

Fig. 4 and Fig. 5 are the B portion enlarged detail among Fig. 2;

Fig. 6 and Fig. 7 are the partial schematic diagram of another embodiment of shell in the utility model;

Fig. 8 is the partial schematic diagram of the another embodiment of shell in the utility model;

(5) specific embodiment: the utility model mainly comprises spindle nose 1 and roll body 2, be provided with shell 3a in roll body 2 peripheries, shell 3a outer surface also can be provided with one deck corrosion-proof wear circle 3b, between shell 3a and roll body 2, leave chamber 9 on an empty stomach, spindle nose 1 at one end and corresponding roll body 2 are provided with through hole 10, and this through hole 10 is communicated with empty stomach chamber 9.In reinforcing ring 5, be provided with some bearing pins 6, connect pressing board 7 and fixedly connected with reinforcing ring 5, at the place, two ends of roll body 2 sealing ring 4 is housed, to prevent the seepage of pressure medium by bearing pin 6.Shell is made for the thin-wall metal material, and outer surface of outer cover also can be provided with one deck corrosion-proof wear circle, and the external cylindrical surface of shell is level and smooth shape, rill shape, blind hole shape.Two ends at shell are provided with reinforcing ring, the sliding fit that slight clearance is arranged between this reinforcing ring and the roll body, guarantee thin-wall metal case regulate in height size expand or can axially freely stretch when shrinking, shell and roll body rotation are to realize by the some bearing pins and the connecting plate that are provided with in the reinforcing ring of shell two ends, the middle height of shell is that the pressure by the pressure medium of the through hole from spindle nose and roll body input forces thin-wall metal case to produce strain to form, and medium-altitude change is to reach by the pressure size of regulating the input pressure medium.

The utility model has all been done improvement on structure and material; can on various paper machines and paper product processing machine, use; and can under non-stop-machine situation, regulate height in required the best arbitrarily; the characteristics that corrosion-proof wear high-strength metal material of selecting for use or nonmetallic materials have long service life can significantly reduce the downtime and the maintenance cost of user factory.
