Description
Technical field
The utility model relates to a kind of screening plant, particularly a kind of rectangle vibrating screen spindle gearing.The utility model belongs to plant equipment and makes processing technique field.
Background technology
The wood chip screening is one of key equipment in wood-based plate, the paper production line.The rectangle vibrating screen is the common equipment that chip screen is chosen, its operation principle is that motor drives the eccentric shaft rotation by belt, the eccentric throw of eccentric shaft is amplitude of fluctuation, and amplitude of fluctuation can be regulated by bolt, and eccentric shaft top drives screen frame by self-aligning bearing and makes eccentric swing, when wood chip falls into sieve nest from top, angle because sieve nest tilts, along with sieve nest swings, wood chip glides, carry out sorting by screen cloth, the wood chip of different size is by different discharging opening output.Be mainly used in that the wood chip to the specification that varies in size carries out sorting in the Chip Production process, its sorting specification can realize by the screen cloth of changing different mesh sizes.
In the prior art, the spindle gearing of rectangle vibrating screen adopts self-aligning roller bearing.It is mainly not enough: owing to the vertical installation of self-aligning roller bearing, roller is monolateral stressed, causes the roller uneven wear serious (1), increases maintenance cost; (2) owing to adopting self-aligning roller bearing, bearing load carrying capacity reduces, and makes auxiliary support arm bear most of axial force, causes the screen frame irregular movement, and greatly shortened service life, and the reciprocating gird utilization ratio is low.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of rectangle vibrating screen spindle gearing of long service life is provided.
For realizing above-mentioned technical purpose, the utility model by the following technical solutions: a kind of rectangle vibrating screen spindle gearing, comprise axle sleeve, be positioned at axle sleeve main shaft, be fixed in the mounting disc on the main shaft and be fixed in balancing weight in the mounting disc, wherein:
---also be provided with the first cylinder roller bearing, locating ring, the second cylinder roller bearing, supporting seat, the first sealing ring, the second sealing ring, the 3rd sealing ring and end cap;
---the first cylinder roller bearing and the second cylinder roller bearing all are socketed on the described main shaft, locating ring is between the first cylinder roller bearing and the second cylinder roller bearing, supporting seat is between the second cylinder roller bearing and described axle sleeve, and end cap is encapsulated in the first cylinder roller bearing and the second cylinder roller bearing in the described axle sleeve;
---the first sealing ring is positioned at the zone that locating ring, the first cylinder roller bearing and described axle sleeve surround, the second sealing ring is located at described main shaft downside, and be positioned at the zone that described main shaft, supporting seat and described axle sleeve surround, the 3rd sealing ring is located at described main shaft upside, and between described main shaft and end cap.
Further, described the second cylinder roller bearing is cylindrical roller thrust bearing.
After adopting technique scheme, the utlity model has following beneficial effect:
(1) adopts two cylinder roller bearings, prevent the monolateral force phenomenon that is subjected to of the self-aligning roller bearing that exists in the prior art, prevent the roller uneven wear, its simple in structure, long service life.
(2) adopt cylindrical roller thrust bearing, offset the axial force that screen frame and material produce, the load when bearing the sieve nest motion, the pressure of the auxiliary support arm of minimizing reciprocating gird, the beat when adapting to better the sieve nest revolution.
The utility model is simple in structure, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1, main shaft, the 2, first cylinder roller bearing, 3, locating ring, the 4, second cylinder roller bearing, 5, supporting seat, the 6, first sealing ring, the 7, second sealing ring, 8, balancing weight, 9, mounting disc, 10, axle sleeve, the 11, the 3rd sealing ring, 12, end cap.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Embodiment
Shown in Fig. 1～2, a kind of rectangle vibrating screen spindle gearing, comprise axle sleeve 10, be positioned at axle sleeve main shaft 1, be fixed in the mounting disc 9 on the main shaft and be fixed in balancing weight 8 in the mounting disc, it also is provided with the first cylinder roller bearing 2, locating ring 3, the second cylinder roller bearing 4, supporting seat 5, the first sealing ring 6, the second sealing ring 7, the 3rd sealing ring 11 and end cap 12.Wherein:
---the first cylinder roller bearing 2 and the second cylinder roller bearing 4 all are socketed on the above-mentioned main shaft 1, locating ring 3 is between the first cylinder roller bearing 2 and the second cylinder roller bearing 4, supporting seat 5 is between the second cylinder roller bearing 4 and above-mentioned axle sleeve 10, and end cap 12 is encapsulated in the first cylinder roller bearing 2 and the second cylinder roller bearing 4 in the above-mentioned axle sleeve 10;
---the first sealing ring 6 is positioned at the zone that locating ring 3, the first cylinder roller bearing 2 and above-mentioned axle sleeve 10 surround.The second sealing ring 7 is located at above-mentioned main shaft 1 downside, and is positioned at the zone that above-mentioned main shaft 1, supporting seat 5 and above-mentioned axle sleeve 10 surround.The 3rd sealing ring 11 is located at above-mentioned main shaft 1 upside, and between above-mentioned main shaft 1 and end cap 12.
