Description

The novel roller assembly that a kind of reducing mechanism is used

One, technical field: the utility model relates to a kind of disintegrating apparatus, the novel roller assembly that particularly a kind of reducing mechanism is used.

Two, background technology: in the prior art, roll the roller assembly that disintegrating apparatus uses and adopt roller sleeve to add the form of bearing pin mostly, simple in structure, cost is low, but its rotation resistance is big thereby working (machining) efficiency is low.

Three, summary of the invention: technical problem to be solved in the utility model provides the roller assembly that a kind of rotation resistance is little, working (machining) efficiency is high.

Technical solution adopted in the utility model is: by roll roller 4 and Roller Shaft 10, roller lining 5, go up

labyrinth sealing member

22 and 20, down labyrinth sealing member 7 and 8 and metal (upper 19 and 13 constitute; Roller Shaft 10 is two-way multidiameter; Rolling roller 4 is a sleeve, and its endoporus has inverted step; Roller lining 5 is shorter than and rolls roller 4, and its outer cylinder has the step that matches with the endoporus that rolls roller 4, and its endoporus above-below direction also all has step; Last labyrinth sealing member 22 is a stationary member, be sleeved on the upper end of Roller Shaft 10, its dynamic component 20 is inverted plate-like, its rim is fixed on the upper surface of roller lining 5 by securing member 18, the dish chamber puts in the upper step endoporus of roller lining 5, the upper bearing (metal) 19 that the upward middle part of dress and Roller Shaft 10 matches in the dish chamber; The lower bearing 13 that the lower step hole dress of roller lining 5 and the middle and lower part of Roller Shaft 10 match; Following labyrinth sealing member 7 is a dynamic component, slightly is plate-like, and its dish chamber puts in the lower step endoporus of roller lining 5, and the rim is fixed on the lower surface of roller lining 5 by securing member 6, and its stationary member 8 is sleeved on the lower end of Roller Shaft 10.

At the place, middle bench hole of roller lining 5, meta bearing 17 and the meta bearing insert 16 that is sleeved on the shoulder place, middle part of Roller Shaft 10 are housed also.

Both ends of the surface in Roller Shaft 10 all have screwed hole of centre, and what link to each other with this screwed hole of centre has upper and lower screw bearing pin 25 and 9.

Roller assembly of the present utility model owing to installed upper and lower bearing additional on Roller Shaft, has improved the stability when the roller rotation rolls, simultaneously, the two ends in Roller Shaft have installed labyrinth-type excluder additional, reduce the resistance of roller rotation, improved the efficient of its processing.Particularly installed the meta bearing of push type additional, improved the axial shock-resistant ability of roller assembly at the middle part of Roller Shaft.

Four, description of drawings:

Accompanying drawing 1 is a main cutaway view of the present utility model;

Accompanying drawing 2 is zoomed-in views of the present utility model.

Five, the specific embodiment:

Below in conjunction with accompanying drawing, describe an embodiment of the present utility model in detail.

Present embodiment be by roll roller 4 and Roller Shaft 10, roller lining 5, go up

labyrinth sealing member

22 and 20, down labyrinth sealing member 7 and 8 and metal (upper 19 and 13, meta bearing 17 and meta bearing insert 16, upper and lower screw bearing pin 25 and 9 constitute.

Roller Shaft 10 is two-way multidiameter, each three grades of step of above-below direction, respectively there is a screw at the center, upper and lower end face, upper and lower screw bearing pin 25 with 9 by screw thread be connected.

Rolling roller 4 is a round buss, and its endoporus has inverted step, and aperture is partly with big end down tapering.

Roller lining 5 is shorter than and rolls roller 4, and its outer cylinder has step and the tapering that matches with the endoporus that rolls roller 4, and both ends of the surface are evenly equipped with several screws.Its endoporus above-below direction also all has step, and one-level is swung in top two-stage, bottom; Last departmental level step matches with member 22, two stage steps dress meta bearing 17 and meta bearing insert 16, and meta bearing insert 16 is sleeved on the third level shoulder place at Roller Shaft 10 middle parts; The bottom is swung to stepped hole and is adorned the lower bearing 13 that matches with the second level, Roller Shaft 10 bottom shoulder.

Last labyrinth sealing member 22 is a stationary member, is the scalariform of falling from power, and mesopore is sleeved on the upper end of Roller Shaft 10, and radially-arranged maze trough is arranged on the step surface.Dynamic component 20 is inverted plate-like, and its rim is fixed on the upper surface of roller lining 5 by securing member 18, the inboard of rim, have with stationary member 22 on the labyrinth ring that matches of maze trough; The dish chamber of its underpart puts in the upper step endoporus of roller lining 5, the dish chamber has inverted stepped hole, behind the dress sealing ring 21 of upper part, be sleeved on the stationary member 22 bottom outer cylinders upper bearing (metal) 19 that the second level, the top step of dress and Roller Shaft 10 matches in the bottom.

Following labyrinth sealing member 8 is a stationary member, and is similar when being inverted to member 22, is sleeved on Roller Shaft 10 lower end first order steps.Dynamic component 7 slightly is plate-like, and its dish chamber puts in the lower step endoporus of roller lining 5; Behind the suit sealing ring 12, overlap the member 8 top cylinder steps of packing in its mesopore; The labyrinth ring of its inboard, lower surface matches with maze trough on member 8 step surfaces; The edge of dish is fixed on the lower surface of roller lining 5 by securing member 6.

Roller assembly of the present utility model with the supporting use of the rotating disk of broken tup, have better effect, common six to eight groups is a cover, be installed in the double-deck clip slot of rotating disk 1, the chute that upper and lower screw bearing pin 25 and 9 passes respectively on the upper and lower laminated plank of rotating disk 1 is connected with the upper and lower side of Roller Shaft 10, between bearing pin and chute inwall,

gap adjustment cover

23 and 11 is housed.Broken tup 26 be contained in rotating disk 1 above, fixing by pressing plate 24 and bolt 3.During use, main shaft 2 drives rotating disk 1 and rotates, at this moment, roller assembly is under centrifugal action, along the chute direction on the upper and lower laminated plank of rotating disk 1 to external pressure, make that roll roller 4 presses to tightly to be contained in and roll liner plate 15 on complete machine cylindrical shell 14 inwalls, under the frictional force effect, rolls roller 4 and does and main shaft 2 rightabout rotations together with roller lining 5.In the middle of in the charging aperture 27 buffer 28 is housed, treats that comminuting matter enters from charging aperture 27, the broken tup 26 that at first is rotated smashes; Tentatively Po Sui material is kicked up again and by tup 26, collides each other again, greatly reduces the granularity of material.At this moment, enter the edge of rotating disk 1 and roll between the liner plate 15, grind material thinner, enter next stage superfine grinding by rolling roller 4 than the material of small grain size.Roller assembly of the present utility model makes that the bearing lubrication in it is fine owing to adopted labyrinth-type excluder at the upper and lower side of Roller Shaft 10, so it is good to roll the rotation of roller 4, rolls the efficient height.
