Abstract
The utility model provides a protector of a vibrating screen bearing, which relates to the field of coal chemical industrial equipment. The protector comprises a rotating shaft, a joint, side plates, a coupler, a motor, vibration exciters, a protective cover, felt, a flange and screw bolts, wherein a motor of a vibrating screen drives two vibration exciters to rotate, the vibration exciters are respectively fixed on the side plates of the vibrating screen, the vibrating screen vibrates through the eccentricity of the vibration exciters, the two vibration exciters are connected through a universal joint, the outwards exposed part of the inner side of each vibration exciter of the vibrating screen is additionally provided with the protective cover, and the protective cover and the rotating shaft of the vibrating screen are sealed through the felt, and are fixed on the side plates through the screw bolts. The utility model is suitable for being used in severe environment with high density of small granular matters such as fine dust, dust and the like in the air, prolongs the service life of the bearing by more than 10 times, saves the overhauling cost, and reduces the production cost.
Description
Technical field
The utility model relates to the Coal Chemical Industry apparatus field, particularly a kind of protective device of vibrating screen bearing.
Background technology
At present, be the thermoelectric field of raw material with the coal, mostly based on coal-powder boiler, fragmentation is sieved after belt conveyer is delivered to the boiler for producing system with raw coal with circular shale shaker by its coal fortune system.The circular shale shaker model of using in this system is: YK2042, because environment is abominable, its bearing length time service is in coal dust, because poor sealing, coal dust enters bearing along turning cylinder, and the mixture of a large amount of coal dusts and lubricating oil is piled up in the bearing slideway, cause bearing wear, bite, regular burning out, even locking have been shortened service life of bearing greatly.Therefore, need the periodic replacement bearing; Not only increase working strength, consumed a large amount of financial resources manpowers, simultaneously regularly stopped overhaul of the equipments, needed load shedding production or stopping production, had a strong impact on output, caused the performance of enterprises to descend.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of protective device of vibrating screen bearing.
The technical solution of the utility model is:
A kind of protective device of vibrating screen bearing; comprise turning cylinder; joint; side plate; shaft coupling; motor; vibrator; also comprise protective cover; felt; ring flange and bolt; the motor of vibratory sieve drives two vibrator rotations by yielding coupling; described two vibrators are separately fixed on the biside plate of vibratory sieve; off-centre by vibrator makes shaker vibration; connect with universal joint between described two vibrators; inboard exposed parts at the vibrator of described vibratory sieve installs described protective cover additional, and the turning cylinder of described protective cover and vibratory sieve is with described felt sealing and by being bolted on the described side plate.
The beneficial effects of the utility model are:
1, the utility model is applicable under the big adverse circumstances of air small particles material densities such as dust, dust and uses, and saved recondition expense more than ten times the service life that prolongs bearing, reduced production cost.
2, protective cover can prevent that a large amount of coal dust alluvials is on turning cylinder, in a single day coal dust drops on and exposes on the turning cylinder, and felt can be wiped it, has prevented that effectively the gap that coal dust drops on turning cylinder upper edge turning cylinder and bearing from entering bearing, cause oil deterioration in the bearing, bearing is regular to be burnt out or locking.
Therefore 3, device connects with bolt and is divided into several, thus change time saving and energy saving.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model A place partial enlarged drawing.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
As Fig. 1, shown in 2, the utility model comprises turning cylinder 1, joint 2, protective cover 3, side plate 4, shaft coupling 5, motor 6, vibrator 7, felt 8, pressing plate 9, bolt 10, the turning cylinder 1 of vibratory sieve is connected with the turning cylinder 1 of motor 6 by shaft coupling 5, shaft coupling 5 is connected with vibrator 7 by joint 2, vibrator 7 is fixed by bolts on the side plate 4, both sides exposed parts at the turning cylinder 1 of vibratory sieve installs protective cover 3 additional, turning cylinder 1 outer end of protective cover 3 and vibratory sieve closely links to each other and by being bolted on the side plate 4, at protective cover 3 with the fixing 8mm felt 8 of the handing-over position usefulness opening flange of the turning cylinder 1 of vibratory sieve.
Outside the utility model can be isolated in a large amount of coal dusts, thereby improve the working environment of bearing, reduced wearing and tearing, regularly bearing is lubricated simultaneously, thoroughly solve the long-term work and frequent fault has reduced loss under adverse circumstances of general bearing, saved cost.
