Abstract
The invention relates to a bearing restraining device outside a tube shell of a spiral conveyer. The gearing restraining device comprises a shell, a spiral shaft is arranged inside the shell and provided with a spiral blade, the shell is fractured, a bearing is arranged at the fractured position of the shell, an inner ring of the bearing is connected with the spiral blade, and an idler wheel arranged outside the inner ring of the bearing is arranged inside an idler wheel holder which is connected with a flange. By the adoption of the structure, compared with a bearing support arranged in a tube, the bearing restraining device has the advantages that no bearing or support is arranged inside the tube, the spiral blade is not fractured and has no notch, and impact, damage and vibration caused to the notch and the support by hard lumps of materials are avoided; the materials are conveyed smoothly, efficiency is improved, and energy consumption and maintenance cost are lowered; noise is reduced, and the working environment is improved; no lubricating oil leaks in the tube, and the materials cannot be polluted.
Description
Technical field
The present invention relates to a kind of conveyer in mechanical field, particularly relate to a kind of conveyor screw shell and retrain bearing arrangement outward.
Background technology
Conveyor screw (claiming again auger) has level, tilts, and vertical three kinds of throughput directions, conveyer is all long, need to screw-conveyer-shaft, bearing support and bearing be set in certain pitch, stablizes screw-conveyer-shaft.Supporting structure is mostly to adopt in auger shell, to add support and bearing is installed at present, as shown in Figure 4, flight 3 is cut off, placing rack 9, support 9 is vertically located on screw conveyor housing 1, screw shaft 2 outer rings are provided with bearing seat 10, but there is following problem in this method: one, this structure of setting up bracket bearing in delivery pipe, use in level, tilt, on the conveyor screw of vertical three kinds of directions, capital stops the convection generation of managing interior material, the degree of being obstructed, vertical maximum, tilt secondly, level is taken second place, transport efficiency reduces by the degree of being obstructed respectively, two, spiral strand sheet, at pipe neck bearing support place, must adopt disconnection strand sheet to dodge bearing support, and spiral twists the discontinuous of sheet, also can lower efficiency, when hard foreign material stream in material send, fall between strand sheet fracture and support and sometimes support or strand sheet are twisted and warped, impact is used, and conveyor screw also can produce vibrations and noisiness simultaneously, three,, because bearing is in delivery pipe, lubricating oil water clock can produce and pollute material, in reality scheme, retrain axle center in addition by the friction of flight and tube wall, thereby reach the object of stablizing twisted axis, this structural friction is large, and noisiness is large, fragile, and maintenance cost is also large.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of conveyor screw shell and retrain bearing arrangement outward, the frictional interface of screw shaft rotating fulcrum, in shell outside, makes flight non-notch; And without bearing and support, there is not the impact damage of material lump to flight breach and support in pipe.
The technical solution adopted for the present invention to solve the technical problems is: a kind of conveyor screw shell retrains bearing arrangement outward, comprise housing, in housing, be provided with screw shaft, screw shaft is provided with flight, and outside is provided with bearing, housing disconnects, bearing is located at housing gap, and the bearing inner ring of bearing connects flight, and bearing inner ring outside is provided with roller, roller is arranged in roller retainer, roller retainer butt flange.
In a preferred embodiment of the present invention, flight is welded on screw shaft by welding manner, and bearing inner ring is welded on flight, and bearing inner ring is followed screw shaft and rotated by same cireular frequency like this.
In a preferred embodiment of the present invention, between bearing inner ring and roller retainer, be provided with seal ring.
In a preferred embodiment of the present invention, seal ring is y-type seal ring, the wearing and tearing of energy automatic compensating, and in the time of seal ring two lateral wearing, seal ring is expanded to both sides from middle, automatic compensating, the service life of prolongation seal ring.
In a preferred embodiment of the present invention, in roller, be provided with high-speed bearing, can be regularly grease-added, because roller is arranged on outside housing, make enclosure interior non lubricant oil water clock, material is not contaminated.
The invention has the beneficial effects as follows: adopt after said structure, bearing support was installed in pipe to be compared, the pipe of the technical program is interior without bearing and support, flight non-notch, there is not impact damage, the vibration of material lump to blade breach and support, material is transported smooth and easy, raise the efficiency, reduce energy consumption and maintenance cost; Reduce noise, improve working environment; Non lubricant oil water clock in pipe, material is not contaminated.

The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
A kind of conveyor screw shell retrains bearing arrangement outward as shown in Figure 1 to Figure 3, comprise housing 1, in housing 1, be provided with screw shaft 2, screw shaft 2 is provided with flight 3, housing 1 outer ring is provided with bearing, housing 1 disconnects, bearing is located at housing 1 gap, bearing inner ring is equivalent to the housing of gap, bearing connects as one the housing of disconnection, coherent housing is before compared in such design, increase the thickness of gap housing, use as raceway, the bearing inner ring 4 of bearing connects flight 3, bearing inner ring 4 outsides are provided with roller 5, roller 5 is arranged in roller retainer 6, roller retainer 6 butt flanges 7, flight 3 is arranged on screw shaft 2 by welding manner, and bearing inner ring 4 is connected with flight 3 by welding manner, between bearing inner ring 4 and roller retainer 6, be provided with seal ring 7, seal ring 7 is y-type seal rings, in roller 5, be provided with high-speed bearing 8.
In the time that screw shaft 2 rotates, screw shaft 2 drives flight 3 to rotate together with bearing inner ring 4, the in-built high-speed bearing 8 of roller 5, roller 5 is fixed on roller retainer 6, be used for restriction and the center of rotation of stable screw shaft 2, the section flange 7 of roller retainer 6 and screw conveyor housing is connected, and completes the integrated connection of conveyer.Because bearing is arranged on outside housing, avoid like this support and bearing to be arranged on the situation in screw conveyor housing, avoid flight to cut off, make flight non-notch, when material transports in pipe, no longer be subject to twisting the obstruction of sheet fracture and internal bearings support, do not have the impact damage of material lump to blade breach and support; And it is unimpeded to make material transport, and raises the efficiency, reduce energy consumption and maintenance cost, reduce noise, improve working environment; , the built-in high-speed bearing of roller can be regularly grease-added, avoided lubricating oil water clock in pipe, makes material not contaminated; Between bearing inner ring 4 and roller retainer 6, sealing member is housed, three forms the roller chamber of sealing, and roller 5 is arranged in roller chamber, has guaranteed the clean of roller, extends the service life of roller.
It is emphasized that: the foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification sheets of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
