Technical field
The utility model relates to a kind of vibrating sieve lubricating fitting, especially for the lubrication sealing structure of the box vibration exciter of vibrating sieve, belongs to the solid separation equipment technical field.
Background technique
Linear vibrating screen directly produces excitation force driving sieve nest by vibration exciter and pumps, and causes material periodically loose, realizes the operations such as dehydration, de-mediated, desliming and classification of material, is a kind of ideal equipment that is widely used in material screening.Box vibration exciter divides two kinds of left and right sides branch mailbox subsumption architecture and eccentric mass external overall structures, regular, the compact structure of left and right sides branch mailbox subsumption architecture outward appearance, but eccentric mass turns round in case and causes vibration exciter heating, and box weight and external dimension are bigger, make inconvenient maintenance, the manufacture cost height.That present widely used eccentric mass external overall structure has is in light weight, lubricated concentrated, easy to maintenance, the characteristics that manufacture cost is lower of compact structure, driving component, more popular with users.But the bearing of this structure adopts grease lubrication at present, bearing can not get lubricated fully, the bearing limit speed is restricted, screen(ing) machine vibration exciter casing bearing heating can occur after the running regular hour, the phenomenon that bearing temperature rise is higher, thus make the limit speed of bearing and be subjected to certain influence working life; In addition, the housing plate sealing part has the oil spout of generation interruption or the phenomenon of continuous oil impregnate behind the running certain hour, and this needing can cause irregular toward the interior interpolation of vibration exciter casing lubricant oil.The problems referred to above all be since lubricating structure that vibration exciter adopts and seal designs not ideal enough due to, thereby be necessary to make improvements.
Summary of the invention
The utility model is used to overcome the defective of prior art and a kind of lubrication sealing structure that is used for the box vibration exciter of vibrating sieve that bearing is carried out reliable thin oil lubricant with special lubricating oil path is provided.
The alleged problem of the utility model is solved by following technological scheme:
A kind of lubrication sealing structure that is used for the box vibration exciter of vibrating sieve, comprise housing bearing seat, bearing, end cap, gear, axle and Sealing in the formation, end cap is positioned at the housing bearing seat end, specialization is: oily pocket 2 and filler opening 3 are set up in described housing bearing seat 1 inner chamber top, and filler opening is positioned at oily pocket bottom, straight-through bearing; Two oil outlets that are obliquely installed 8 are set up in described housing bearing seat bottom, and oil outlet connects housing bearing seat, described filler opening diameter d

2=1.1～1.4.
The above-mentioned lubrication sealing structure that is used for the box vibration exciter of vibrating sieve, described two oil outlets, 8 relative filler openings 3 are symmetrical arranged, angle δ=100 between two oil outlets °～130 °, the inclination angle of oil outlet and axis is 5 °～15 °.
The above-mentioned lubrication sealing structure that is used for the box vibration exciter of vibrating sieve, described Sealing 6 is between end cap 7 and axle 5, and Sealing is the skeleton seal rings of the lips of two series connection.
The utility model improves at the problem that leakage of oil easily takes place the lubricated insufficient and sealing part of common box vibration exciter bearing, its main feature is as follows: 1. set up oily pocket and filler opening on housing bearing seat inner chamber top, set up two return openings in the housing bearing seat bottom, lubricating system forms splashing of lubricant oil by the high speed rotating of gear, come the oil-collecting oil-feed by oily pocket, filler opening, return opening has at an angle guaranteed to concentrate in the bearing enough lubricant oil that it is lubricated, it is lubricated fully that this structure can make bearing obtain, and bearing life can significantly improve; 2. adopt the skeleton black box of dual tandem lips, can effectively prevent the splash of lubricant oil, the sealing structure can be used on that pressure oscillation is big, the higher place of Sliding velocity, and has resistant to elevated temperatures effect.Based on above-mentioned advantage, the utlity model has characteristics simple in structure, easy to make, that using effect is good, be used for all having a good application prospect on box vibration exciter of vibrating sieve or the Other related equipment.
Description of drawings
Fig. 1 is structural representation of the present utility model (the B-B revolved sectional view of Fig. 3);
Fig. 2 is the C portion partial enlarged view of Fig. 1;
Fig. 3 is the A-A cross section partial sectional view of Fig. 1.
Number in the figure is expressed as follows: 1. housing bearing seat; 2. oily pocket; 3. filler opening; 4. bearing; The axle; 6. Sealing; 7. end cap; 8. oil outlet; 9. lubricant oil; 10. gear.
Embodiment
Referring to Fig. 1, Fig. 3, during constituting, the utility model comprises housing bearing seat 1, bearing 4, end cap 7, gear 10, axle 5 and Sealing 6, and end cap is positioned at the housing bearing seat end, and the bearing after the improvement, gear all adopt gear splashing thin oil lubricant mode.Set up oily pocket 2 and filler opening 3 on casing bearing 1 inner chamber top, filler opening is positioned at oily pocket bottom, straight-through bearing, and the perforate of oil duct flows into its inside on the process bearing.Set up two oil outlets that are obliquely installed 8 in the housing bearing seat bottom, oil outlet connects housing bearing seat, two oil outlets, 8 relative filler openings 3 are symmetrical arranged, angle δ=100 between two oil outlets °～130 °, and the inclination angle of each oil outlet and axis is 5 °～15 °.For guaranteeing the good lubricating status of bearing, filler opening diameter d
