Abstract
The utility model discloses a kind of lower bearing component of launder washer, comprise bearing support and bearing shell.Bearing support is diamond type seat, bearing shell is the annulus of teflon, and its overcoat has round steel pipe, is connected with the diamond type framework of coupling between the outer wall of round steel pipe and bearing support, clog rubber mat plate between the bottom side of diamond type framework and bearing support, the inside and outside wall of annulus all offers circular groove.The screw axis bottom of launder washer is inserted in annulus, when screw axis rotates, the pressure that in annulus, water lubrication produces makes screw axis and annulus depart from, the longitudinal center line of screw axis and annulus is overlapped, a circle moisture film is had to be held up by screw axis between the outer wall of screw axis and circle ring inner wall, make screw axis steady motion, and the kinetic friction between itself and annulus is reduced greatly, the material of annulus is made to adopt teflon to meet usage requirement, greatly reduce cost of material and improve sealability, reduce the probability that silt enters bearing shell inside, extend the working life of bearing shell.
Description
Technical field
The utility model relates to a kind of for launder washer, is specifically related to a kind of launder washer lower bearing component structure.
Background technique
Launder washer is mainly used in bauxite washup operation, also can carry out desliming operation by the ore many to other clay content.Extensive use be double-screw shaft launder washer, its working principle is that two rotatingshafts rotate in opposite directions simultaneously, and the stator blade on band moving axis inserts in ore pulp, scrubbing action is carried out to ore, the mud that ore is stained with is removed, to reach the object that ore and mud carry out being separated, obtains clean ore.
The bearing shell of current launder washer lower bearing is split-type structural, because bearing support is diamond type seat, so the outer wall shape of upper and lower two pieces of bearing shells is polygonal, in use there is following unfavorable factor in this bearing bush structure: one, the overload of bearing shell, every root axle add leaf quality have six tons multiple, be singly that the dead load of afterbody just has more than 3 tons; They are two years old; Bearing shell suffers greater impact power, and because spiral shaft vane is to the shampooing active force of ore, ore also produces opposed impact power to screw axis, and its impact force action is on the bearing shell of lower bearing; Its three, bearing shell working condition is severe, and because long period of soaking is in ore pulp, silt particle easily enters in lower bearing in equipment operation.
Above-mentioned unfavorable factor directly causes the working life of lower bearing bearing shell short, shows to run under normal circumstances just to change this bearing shell the 2-3 month.And its material is made up of teflon interpolation tin lead bronze metallics, the bush material weight of a pair subdivision 15 kilograms, its expense is about 3,000 yuan.The lower bearing bearing shell of two screw axis is exactly 6,000 yuan.The trough washer quantity that usual bargh comes into operation is up to up to a hundred, and the consumption of its lower bearing bearing shell is also very huge, and cost is very high.
Model utility content
The purpose of this utility model is to provide that a kind of cost is low, the step bearing shell of long service life.
The utility model discloses a kind of lower bearing component of launder washer, comprise bearing support and bearing shell, the relative position of bearing shell and bearing support offers high-pressure water seal interface.Described bearing shell is the annulus of teflon, and its overcoat has round steel pipe.
Described bearing support is diamond type seat.The inside and outside wall of described high-pressure water seal jointing all offers circular groove.The circular groove of outer wall plays connection effect, outside press water is made to enter in bearing shell along circular groove, the outer ring making on the other hand to be equivalent between bearing shell and round steel pipe general bearing with have relative slip between inner ring, make the wearing and tearing of bearing shell evenly, be conducive to the stability improving screw axis motion, reduce the impact force to bearing support.
The diamond type framework of coupling is connected with between the outer wall of described round steel pipe and described bearing support.
The upside of described diamond type framework is opening side.
Clog rubber mat plate between the bottom side of described diamond type framework and described bearing support, to reduce the impact force of screw axis to bearing support, improve the pliability of screw axis.Improve screw axis workmanship and extend axle its working life simultaneously.
Working principle of the present utility model is as follows: the annulus being equipped with teflon in the inside of one section of round steel pipe, and the screw axis bottom of launder washer is inserted in annulus, and the inside and outside wall of the corresponding high-pressure water seal jointing of annulus all offers circular groove.When screw axis rotates, the pressure that in annulus, water lubrication produces makes screw axis and annulus depart from, the longitudinal center line of screw axis and annulus is overlapped, a circle moisture film is had to be held up by screw axis between the outer wall of screw axis and circle ring inner wall, make screw axis steady motion, and the kinetic friction between screw axis and annulus is reduced greatly, make the material of annulus adopt teflon to meet usage requirement.Bearing shell adopts one section of annulus, and its material only has 1/4th of prior art on the one hand, also need not add metallics, greatly reduce cost of material; Also substantially increase sealability on the other hand, decrease the probability that silt enters bearing shell inside, extend the working life of bearing shell.
In a word, circular unitary bearing bush structure of the present utility model improves and material improvement is after teflon, compares have that cost is low, sealability is high and the advantage of long service life with prior art.

Embodiment
As shown in Figure 1, the utility model discloses a kind of lower bearing component of launder washer, comprise bearing support 1, bearing shell 2, round steel pipe 3 and diamond type framework 4.Bearing shell 2 is the annulus of polyfluortetraethylene pipe, is placed in round steel pipe 3, and the inwall of diamond type framework 4 is external in the inwall being connected to bearing support 1 in the outer wall of round steel pipe 3, outer wall.The upside of diamond type framework 4 is opening side, has rubber mat plate 5 between its bottom side and bearing support 1.The corresponding position of bearing support 1, bearing shell 2 and round steel pipe 3 offers high-pressure water seal interface, the outer termination high-pressure water pipe of this interface.
As shown in Figure 3, the inside and outside wall of the corresponding high-pressure water seal jointing of bearing shell 2 all offers circular groove
.
As shown in Figure 4, Figure 5, the bearing shell of prior art lower bearing is split-type structural, is surrounded form by top bearing shell and lower bearing, and such silt is easy to enter in bearing shell from splicing seams, affects its working life.
Working principle of the present utility model is as follows: the annulus being equipped with teflon in the inside of one section of round steel pipe, and screw axis 6 bottom of launder washer is inserted in annulus, and the inside and outside wall of annulus all offers circular groove.When screw axis rotates, the pressure that in annulus, water lubrication produces makes screw axis and annulus depart from, the longitudinal center line of screw axis and annulus is overlapped, a circle moisture film is had to be held up by screw axis between the outer wall of screw axis and circle ring inner wall, make screw axis steady motion, and the kinetic friction between screw axis and annulus is reduced greatly, make the material of annulus adopt teflon to meet usage requirement.Bearing shell adopts one section of annulus, and its material only has 1/4th of prior art on the one hand, also need not add metallics, greatly reduce cost of material; Also substantially increase sealability on the other hand, decrease the probability that silt enters bearing shell inside, extend the working life of bearing shell.
