Description
Technical field
The utility model relates to a kind of comminutor, specifically the pressure roller of comminutor.
Background technology
Comminutor is the extruding and the discharging that are realized material by extrusion device.Extrusion device comprises press-roller device and ring mould, by the acting in conjunction of press-roller device and environmental protection, is exported by express material from the discharge opening of ring mould.The pressure roller of press-roller device is rotating to be connected on roller seat.
Pressure roller is made up of two large divisions, and one is roller skin, and a roll shaft, roller skin is predefined on roll shaft by bearing.Bearing is positioned at the inside of roller skin, so the lubrication of bearing has just become an insoluble problem.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and provides the pressure roller with lubricating bearings.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of comminutor pressure roller; comprise roll shaft and be fixed on the roller skin on described roll shaft by bearing; it is characterized in that: on described roll shaft, be processed with the passage for lubricating described bearing; described passage comprises along the first passage of described roll shaft axis and the second channel along described roll shaft radial direction; described first passage is communicated with second channel, is connected with oil nozzle at the entrance of described first passage.
Described roll shaft is also provided with a labyrinth oil ring, this labyrinth oil ring is provided with another oil nozzle, described labyrinth oil ring is made up of retainer ring and swivel becket, described retainer ring is fixedly connected with described roll shaft, described swivel becket is fixedly connected with described roller skin, described swivel becket is provided with cannelure, and described retainer ring is positioned at described cannelure.
Described cannelure is multiple tracks.
Compared with prior art, the utility model offers the passage of lubricating bearings on roll shaft, and on roll shaft, increase labyrinth oil ring, while lubricating bearings, also serves sealing function, can not cause the leakage of oil situation of lubricating oil.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, roll shaft, 2, roller skin, 3, bearing, 4, swivel becket, 5, fixing ring flat-plate, 6, passage, 7, oil nozzle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model elaborates:
As shown in Figure 1, a kind of comminutor pressure roller of the utility model, comprises roll shaft 1, roller skin 2 and bearing 3.Roller skin 2 is fixed on roll shaft 1 by bearing 3.Roll shaft 1 is processed with the passage 6 for lubricating bearings 3, passage 6 l-shaped, comprise along the first passage of roll shaft axis and the second channel along roll shaft radial direction, first passage is communicated with second channel, is connected with oil nozzle 7 at the entrance of passage 6 and the entrance of first passage.
In order to prevent leakage of oil and improve sealing, roll shaft 1 is also provided with a labyrinth oil ring, labyrinth oil ring is provided with another oil nozzle, labyrinth oil ring is made up of retainer ring 5 and swivel becket 4, swivel becket 4 is provided with multiple tracks cannelure, and retainer ring 5 is positioned at cannelure.Wherein, retainer ring 5 be fixed on roll shaft 1, swivel becket 4 is fixed on roller skin 2.
