Abstract
The utility model discloses an improved vibrating screen bearing box, which belongs to the technical field of vibrating screen devices, and is used for guaranteeing that a vibrating screen runs stably and a bearing is easy to be mounted and dismounted. According to the technical scheme, the improved vibrating screen bearing box comprises a bearing seat, a bearing, an oil stop ring and a gland, wherein a semicircular key is additionally arranged on a contact surface of the inner wall of the bearing seat and each outer ring of a bearing; and the inner wall of the bearing seat and the outer ring of the bearing are in interference fit, wherein an interference magnitude is less than or equal to 0.02mm. According to the improved vibrating screen bearing box, the semicircular key is additionally arranged on the contact surface of the inner wall of the bearing seat and the outer ring of the bearing, and due to the semicircular key, a relative rotation displacement of the outer ring of the bearing relative to the inner wall of the bearing seat does not happen; and meanwhile, the interference magnitude of the inner wall of the bearing seat and the outer ring of the bearing are not large, thereby facilitating a bench worker to conveniently mount and dismount the bearing box. By virtue of the improved vibrating screen bearing box, under the frequently variable load action of a screening machine, the use reliability of the screening machine can be guaranteed, and the overall service life of the whole screening machine is prolonged; and the improved vibrating screen bearing box is convenient to mount and dismount while ensuring the overall reliability of the screening machine, so that the maintaining difficulty and work load of a worker are relieved and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of vibrating screen bearing case, belongs to the vibrating sieve equipment technical field.
Background technique
The vibrating screen bearing case mainly is made of bearing support, bearing, oil flinger ring and gland.Oil flinger ring is positioned at the neutral position of bearing support, two dish bearing outsides by with the both sides at oil flinger ring of being fixed of bearing support inwall, two glands are fixed on the both sides of bearing support, simultaneously bearing outer ring is carried out axial limiting, bearing support is fixed on the side plate of screen(ing) machine by its peripheral high-strength bolt.The problem that present vibrating screen bearing case exists mainly is: because the load that vibrating sieve bears in normal operation is changeable, the stiction holding position of the axial force of very difficult pressured lid and bearing support inwall and bearing itself is constant for bearing, and impact force is as long as the power of bearing greater than bearing itself will cause the relative bearing support of bearing outer ring that rotation displacement is arranged.In case rotation displacement appears in bearing, bearing generates heat rapidly, and the time has been grown and can cause bearing expansion locking, working speed can occur simultaneously and turn less, and Caused Vibration direction angle 360 degree non-directionals, material can not be got rid of compass screen surface.Usually the technician for increase the fastness of bearing at bearing support mainly be by bearing outer ring and bearing support inwall cooperate finish, but the matching allowance of bearing outer ring and bearing support inwall is difficult to hold, magnitude of interference is too large, assembling and dismounting are difficult to, magnitude of interference is too little, is difficult to then guarantee that screen(ing) machine runs well.The stability that therefore, how can guarantee screen(ing) machine considers that again the easness of pincers worker assembling is the difficult problem that the technician need to solve.
The model utility content
Technical problem to be solved in the utility model provides a kind of improved vibrating screen bearing case, this vibrating screen bearing case can guarantee that bearing outer ring is with respect to the bearing support displacement that can not rotate, guarantee that whole screen(ing) machine runs well, simultaneously assembly and disassembly are easy to again.
The technological scheme that solves the problems of the technologies described above is:
A kind of improved vibrating screen bearing case, it is comprised of bearing support, bearing, oil flinger ring and gland, bearing support is bolted on the side plate of vibrating sieve, gland is bolted on the bearing support, oil flinger ring is installed in bearing support bosom position, a bearing is installed respectively in the oil flinger ring both sides, and its improvements are, increases woodruff key at the surface of contact of bearing support inwall and each bearing outer ring.
Above-mentioned improved vibrating screen bearing case, described bearing support inwall and bearing outer ring are interference fit, magnitude of interference is≤0.02mm.
Above-mentioned improved vibrating screen bearing case, woodruff key on the surface of contact of described bearing support inwall and each bearing outer ring is 1-3, they are along bearing support inwall and bearing outer ring circumference uniform distribution, inwall at bearing support is processed with semicircle keyway, is processed with the plane that semicircle key is installed in the outer ring of bearing.
The beneficial effects of the utility model are:
The utility model increases woodruff key at the surface of contact of bearing support inwall and bearing outer ring, woodruff key can not make the relative bearing support inwall of bearing outer ring displacement occur relatively rotating, bearing support inwall and bearing outer ring is that value of interference fit is little simultaneously, pincers worker assembling and convenient disassembly.The utility model can guarantee the reliability used under the frequent changeable load of screen(ing) machine, improved the working life of screen(ing) machine integral body, when guaranteeing the screen(ing) machine global reliability, be convenient to again assembling and dismounting, alleviated workman's maintenance difficulty and workload, improved working efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Mark is as follows among the figure: bearing support 1, bolt 2, gland 3, axle 4, bearing 5, woodruff key 6, oil flinger ring 7.
Embodiment
The utility model is comprised of bearing support 1, bearing 5, oil flinger ring 7 and gland 3.
Show among the figure, bearing support 1 periphery is bolted on the side plate of vibrating sieve, gland 3 is fixed on the bearing support 1 by its periphery screw and bolt 2, oil flinger ring 7 is installed in bearing support 1 bosom position, a bearing 5 is installed respectively in oil flinger ring 7 both sides, bearing 5 is fixed on by interference fit on the inwall of bearing support 1, and axle 4 is installed in the inner ring of bearing 5, and oil flinger ring 7, the bearing 5 of bearing support 1 inside carry out axial limiting by the seam on the gland 3.
Show among the figure, bearing support 1 inwall and bearing 5 outer rings are interference fit, and the magnitude of interference between bearing support 1 inwall and bearing 5 outer rings is≤0.02mm that this magnitude of interference is little, easily dismounting.Simultaneously set up woodruff key 6 at the surface of contact of bearing support 1 inwall and each bearing 5 outer rings, woodruff key 6 is 1-3, they are along bearing support 1 inwall and bearing 5 outer ring circumference uniform distributions, inwall at bearing support 1 is processed with semicircle keyway, is processed with the plane that semicircle key is installed in the outer ring of bearing 5.
After adopting said structure, screen(ing) machine relies on the effect of woodruff key 6 relative bearing support 1 inwall in bearing 5 outer rings can not occur when load is changeable displacement to occur relatively rotating, simultaneously pincers worker assembling and dismounting are also very convenient, have guaranteed the operational safety of screen(ing) machine, the working life of improving screen(ing) machine integral body.
