Abstract
The utility model discloses a kind of combination sealing arrangement be applied in vibratory sieve, belong to vibratory sieve technical field, mainly solve existing vibrating screen bearing sealing place leakage of oil and enter the technical problem of dust, its technical scheme is that the bearing block of this device is connected with bearing cap, bearing cap is designed with sealed groove, bearing cap by sealed groove and the flange on gland mutually nested become labyrinth seal structure, on gland, cover has y-type seal ring, y-type seal ring is with secondary lip, mutually nested with bearing cap, form contact seal; It is bushing mutually that the utility model bearing cap and gland pass through sealed groove, and composition labyrinth seal, can effectively prevent dust from entering bearing, y-type seal ring with secondary lip is enclosed within gland, simultaneously mutually nested with bearing cap again, form contact seal, effectively prevent lubricating oil to leak.
Description
Technical field
The utility model relates to vibratory sieve, is specially a kind of combination sealing arrangement be applied in vibratory sieve.
Background technology
Vibratory sieve is a kind of screening plant being applied to the industries such as coal, metallurgy, water power, mine, building materials, chemical industry, electric power, traffic, harbour of reciprocating vibration utilizing oscillator exciting to produce, thin oil vibratory sieve is the one in vibratory sieve, due to it, to have exciting force large, features such as bearing load is little, temperature is low, and noise is little and be able to extensive use; Because the vibrator of this vibratory sieve all adopts bearing thin oil to lubricate in prior art, after long-time use, there is oil leakage phenomenon in various degree in bearing seal place, particularly in mine, coal, metallurgy industry, because in working environment, dust is large, in the lubricating oil that poor sealing causes dust to invade in bearing, and then cause bearing lubrication bad, greatly shorten the service life of vibratory sieve.
Utility model content
The utility model, for above-mentioned technical problem, proposes a kind of combination sealing arrangement be applied in vibratory sieve, and this device can effectively stop lubricating oil to leak outside, and can prevent again dust from invading.
In order to realize final purpose described in the utility model, intend adopting following technology:
A kind of combination sealing arrangement be applied in vibratory sieve, comprise eccentric shaft (1), seamless steel pipe (3), double-row self-aligning roller bearing (4), described double-row self-aligning roller bearing (4) inner ring arranges and is fixed on the predetermined installation site of eccentric shaft (1), double-row self-aligning roller bearing (4) outer ring is fixed in bearing block (5), described bearing block (5) has bearing cap (8) by bolt-connection, bearing cap (8) is designed with sealed groove, bearing cap (8) by sealed groove and the flange on gland (9) mutually nested become labyrinth seal structure, the upper cover of described gland (9) has y-type seal ring (10), y-type seal ring (10) is with secondary lip, mutually nested with bearing cap (8), form contact seal.
The utility model bottom bracket (5) is fixed on screen box by high-strength bolt, and bearing cap (8) is connected with bearing block (5) by bolt, and double-row self-aligning roller bearing (4) is fixed on the predetermined installation site of eccentric shaft (1).Y-shaped ring (10) with secondary lip is enclosed within gland (9), by flywheel (6), gland (9) is fixed on installation site, and bearing cap (8) is designed with groove, and gland (9) is designed with flange, and the two nests together composition labyrinth seal structure.
The beneficial effects of the utility model are: it is bushing mutually that bearing cap and gland pass through sealed groove, and composition labyrinth seal, can effectively prevent dust from entering bearing; Y-type seal ring with secondary lip is enclosed within gland, simultaneously mutually bushing with bearing cap again, forms contact seal, effectively prevents lubricating oil to leak.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model hermetically-sealed construction enlarged drawing.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of combination sealing arrangement be applied in vibratory sieve, comprise eccentric shaft 1, seamless steel pipe 3, double-row self-aligning roller bearing 4, described double-row self-aligning roller bearing 4 inner ring arranges and is fixed on the predetermined installation site of eccentric shaft 1, double-row self-aligning roller bearing 4 outer ring is fixed in bearing block 5, described bearing block 5 has bearing cap 8 by bolt-connection, bearing cap 8 is designed with sealed groove, bearing cap 8 by sealed groove and the flange on gland 9 mutually nested become labyrinth seal structure, on described gland 9, cover has y-type seal ring 10, y-type seal ring 10 is with secondary lip, mutually nested with bearing cap 8, form contact seal.
Operation principle of the present utility model is: vibratory sieve before activation, unclamp oil level and check rod 2, appropriate thin oil is injected as lubricating oil in seamless steel pipe 3, when oil level inspection rod 2 just has lubricating oil to overflow, illustrate that lubricating oil has just in time flooded 1/3 of double-row self-aligning roller bearing 4 bottom roller, stop refueling.After Vibration on Start-up sieve, by the power transmission of belt pulley 7, when eccentric shaft 1 operates, have a small amount of lubricating oil to be got rid of in cavity I, the y-shaped ring 10 with secondary lip can effectively stop lubricating oil to leak.
Claims (1)
1. one kind is applied to the combination sealing arrangement in vibratory sieve, comprise eccentric shaft (1), seamless steel pipe (3), double-row self-aligning roller bearing (4), described double-row self-aligning roller bearing (4) inner ring arranges and is fixed on the predetermined installation site of eccentric shaft (1), double-row self-aligning roller bearing (4) outer ring is fixed in bearing block (5), it is characterized in that: described bearing block (5) has bearing cap (8) by bolt-connection, bearing cap (8) is designed with sealed groove, bearing cap (8) by sealed groove and the flange on gland (9) mutually nested become labyrinth seal structure, the upper cover of described gland (9) has y-type seal ring (10), y-type seal ring (10) is with secondary lip, mutually nested with bearing cap (8), form contact seal.
