Description
Technical field
The utility model is related to mining machinery technical field, more particularly to a kind of vibrating feed eccentric drive shaft shaft end seal knot
Structure.
Background technology
Oscillating feeder is the device for continuously and uniformly providing material for disintegrating machine in sandstone production line, can avoid crushing
Machine receiving opening is blocked.Oscillating feeder utilizes the centrifugal force that vibrating device is produced, and material is with screen box on inclined compass screen surface
Make continuous sling movement, and continuously and uniformly deliver to material in receiving opening.Vibrating device conduct is used in oscillating feeder
Exciting source, usual vibrating device uses eccentric shaft, and eccentric shaft is arranged on the sieve nest of oscillating feeder, in the driving of motor
It is lower to be rotated, vibrate sieve nest.Eccentric shaft needs plus Huang in rotation process in the bearing that eccentric shaft two ends are connected
Oil is lubricated, but existing bearing seal structure sealing property is poor, causes butter can be from shaft end both sides to outward leakage, so
Not only it is difficult to play good lubricant effect, while be leaked to the butter of eccentric shaft side can also cause one to the work of eccentric shaft
Fixed influence.
Utility model content
The purpose of this utility model is to solve existing vibrating feed eccentric drive shaft sealing structure of shaft end in sealing property
The technical problem of presence can effectively solve shaft end butter leakage there is provided a kind of vibrating feed eccentric drive shaft sealing structure of shaft end
Problem.
In order to solve the above technical problems, the utility model employs following technical scheme：
Central tube is provided with vibrating feed eccentric drive shaft sealing structure of shaft end, oscillating feeder sieve nest, eccentric shaft is set
In central tube, eccentric shaft two ends are stretched out from central tube pipe end, and bearing and bearing are disposed between eccentric shaft and central tube
Seat, the bearing is set on eccentric shaft, and bearing block is fixedly mounted on central tube pipe end, and bearing is arranged in bearing block, bearing
Seat outside is provided with bearing cap；Oil scraper ring is provided with the inside of the bearing, oil scraper ring is fixedly installed in bearing block.
In above-mentioned technical proposal, further, the bearing block inner opposite end sets restraining position ring block, and oil scraper ring is arranged on axle
Hold between spacing ring, and be pressed abd fixed on by bearing on spacing ring.
In above-mentioned technical proposal, further, sealing gasket is provided between the oil scraper ring and spacing ring.
In above-mentioned technical proposal, further, oil scraper ring is provided between the bearing and bearing cap, oil scraper ring is arranged on
In bearing block, fixed and held out against in bearing face by bearing cap.
In above-mentioned technical proposal, further, sealing ring is provided between the bearing cap and eccentric shaft.
The utility model sets oil scraper ring respectively in bearing both sides, prevents the butter in bearing block from being leaked out from bearing both sides
Come, the lubrication of bearing and normal operation has not only been effectively ensured, exist while butter can be solved and entered after central tube to eccentric shaft
Influence.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1st, sieve nest, 2, central tube, 3, eccentric shaft, 4, bearing, 5, bearing block, 6, bearing cap, 7, oil scraper ring, 8, limit
Position ring, 9, sealing gasket, 10, sealing ring.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, being provided with central tube 2 in the present embodiment on oscillating feeder sieve nest 1, eccentric shaft 3 is centrally disposed
In pipe 2, the two ends of eccentric shaft 3 are stretched out from the pipe end of central tube 2, and bearing 4 and bearing are disposed between eccentric shaft 3 and central tube 2
Seat 5, bearing 4 is set on eccentric shaft 3, and bearing block 5 is fixedly mounted on the pipe end of central tube 2, and bearing block is bolted here
On sieve nest.Bearing 4 is arranged in bearing block 5, and the outside of bearing block 5 is provided with bearing cap 6, and bearing cap is bolted
On bearing block.The inner side of bearing 4 is provided with oil scraper ring 7, and oil scraper ring 7 is fixedly installed in bearing block 5；Such as Fig. 1, bearing block
5 inner opposite ends set restraining position ring block 8, and oil scraper ring 7 is arranged between bearing 4 and spacing ring 8.During installation, first oil scraper ring is installed
Into bearing block, then bearing is installed, compressing oil scraper ring by bearing is fixed.Preferably, in oil scraper ring 7 and spacing ring 8
Between be provided with sealing gasket 9, be easy to the installation of oil scraper ring, at the same increase oil scraper ring sealing property.
In the present embodiment, oil scraper ring 7 is set between bearing 4 and bearing cap 6, and oil scraper ring 7 is arranged in bearing block 5, led to
The fixation of bearing cap 6 is crossed to hold out against in the end face of bearing 4；Set oil scraper ring that butter can be prevented to outward leakage in outside.In bearing cap 6 and partially
Sealing ring 10 is set between heart axle 3, increases the sealing property of sealing structure.
Oil inlet passage is set on bearing block, butter is added into bearing by oil inlet passage, is that bearing is lubricated, this is close
Seal structure prevents the butter in bearing block from being leaked from bearing both sides, not only by setting oil scraper ring respectively in bearing both sides
The lubrication of bearing and normal operation is effectively ensured, while can solve butter enters the influence existed after central tube to eccentric shaft.
Specification and drawings of the present utility model are considered as illustrative and not restrictive, on the utility model basis
On, those skilled in the art are according to disclosed technology contents, it is not necessary to which performing creative labour just can be to some of technologies
Feature makes some and replaces and deform, in protection domain of the present utility model.
