Abstract
The utility model discloses a circular vibrating screen's vibrator sealing mechanism, including eccentric shaft and stabilizer, be equipped with sealing mechanism between eccentric shaft and the stabilizer, the eccentric shaft overcoat has a barrel, and space between eccentric shaft and the barrel is the machine oil passageway, sealing mechanism including overcoat in proper order at epaxial bearing of off -centre and seal cover, the seal cover is close to the stabilizer, the bearing overcoat is equipped with the bearing box, and the seal cover overcoat is equipped with bearing cap, bearing box and bearing cap fixed connection. Has following advantage: because add seal cover and O type circle, increased sealed effect, effectively avoided the oil leak phenomenon, because of being provided with the labyrinth oil duct, the quality of lubricating oil has been guaranteed in the invasion of effectual control dust, and the extension is to the life of bearing, has further improved the production efficiency of shale shaker, has reduced manufacturing cost for the user.
Description
Technical field
This utility model relates to the vibrator sealing mechanism of a kind of circular shale shaker.
Background technology
Circular shale shaker is a kind of necessary equipment being widely used in and carrying out sieve classification operation in the industries such as mine, metallurgy, building materials, food.Eccentric shaft is contained in cylinder, and two ends, equipped with stabilizer, rotate under motor drives, form an inertia vibrator.The exciting force of vibrator makes screen box produce the circular or vibration of elliptic motion trace, and material is sized during screen cloth upthrow rises and falls.
The sealing means of existing circular shale shaker vibrator is undesirable, and outside framework oil seal rubs on the eccentric shaft run up, and causes outside framework oil seal to lose efficacy and produces oil leakage phenomenon.
Utility model content
Technical problem to be solved in the utility model is to provide the vibrator sealing mechanism of the circular shale shaker of a kind of good sealing effect.
For solving above-mentioned technical problem, the vibrator sealing mechanism of the circular shale shaker that this utility model provides, it includes eccentric shaft and stabilizer, is provided with sealing mechanism, is cased with cylinder outside described eccentric shaft between eccentric shaft and stabilizer, space between eccentric shaft and cylinder is oil passageway, sealing mechanism includes the outer bearing being enclosed within eccentric shaft and sealing shroud successively, and described sealing shroud is near stabilizer, and described bearing outside is provided with bearing box, being arranged with bearing cap outside sealing shroud, bearing box is fixing with bearing cap to be connected.Set up sealing shroud, improve the sealing property of mechanism.
As preferably, described bearing cap is provided with the axis parallel of the longitudinal groove and lateral trench being mutually perpendicular to interlock, described lateral trench and eccentric shaft.Longitudinal groove connects with oil passageway with lateral trench, forms labyrinth type oil duct, and the effective dust that controls enters in device.
As preferably, between described bearing cap and sealing shroud, it is provided with two outside framework oil seals.Improve sealing effectiveness further.
As preferably, between described sealing shroud and eccentric shaft, it is provided with O.Improve sealing further.
As preferably, described sealing shroud is pressed close to the end face of bearing cap and is provided with annular table of turning up, bearing cap be provided with turn up annular table with the use of annular slot.It is easily installed location.
After using above structure, the vibrator sealing mechanism of circular shale shaker of the present utility model compared with prior art, having the advantage that because being additionally arranged sealing shroud and O, adding sealing effectiveness, effectively prevent oil leakage phenomenon；Because being provided with labyrinth type oil duct, the effective invasion controlling dust, it is ensured that the quality of lubricating oil, extend the service life to bearing, further increase the production efficiency of vibrosieve, reduce production cost to user.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein: 1, eccentric shaft, 2, stabilizer, 3, cylinder, 4, machine oil, 5, bearing, 6, sealing shroud, 7, bearing box, 8, bearing cap, 9, longitudinal groove, 10, lateral trench, 11, outside framework oil seal, 12, O, 13, annular table of turning up.
Detailed description of the invention
The utility model will be further described to combine accompanying drawing below by embodiment.
nullAs shown in Figure 1，The vibrator sealing mechanism of the circular shale shaker that the present embodiment provides，It includes eccentric shaft 1 and stabilizer 2，It is provided with sealing mechanism between eccentric shaft 1 and stabilizer 2，It is cased with cylinder 3 outside described eccentric shaft 1，Space between eccentric shaft 1 and cylinder 3 is oil passageway，Flow for machine oil 4，Sealing mechanism includes the outer bearing 5 being enclosed within eccentric shaft 1 and sealing shroud 6 successively，Described sealing shroud 6 is near stabilizer 2，It is arranged with bearing box 7 outside described bearing 5，Bearing cap 8 it is arranged with outside sealing shroud 6，Bearing box 7 is fixing with bearing cap 8 to be connected，Described bearing cap 8 is provided with the longitudinal groove 9 and lateral trench 10 being mutually perpendicular to interlock，Described lateral trench 10 and the axis parallel of eccentric shaft，Longitudinal groove 9、Lateral trench 10 and oil passageway constitute labyrinth type oil duct，Effectively control the invasion of dust.
It is provided with two outside framework oil seals 11 between described bearing cap 8 and sealing shroud 6, between described sealing shroud 6 and eccentric shaft 1, is provided with O 12.
The end face that bearing cap 8 pressed close to by described sealing shroud 6 is provided with annular table 13 of turning up, bearing cap 8 be provided with turn up annular table 13 with the use of annular slot.
