Abstract
The utility model relates to a front axle bearing preload adjustment assembly for a large-scale mine dumper, belonging to the field of engineering machinery technology and comprising a bearing positioning plate, bolts, a knuckle spindle and a spacer shim and also comprising two depth measurement holes symmetrically distributed on the bearing positioning plate, wherein the spacer shim is arranged between the bearing positioning plate and the knuckle spindle; and the bearing positioning plate, the spacer shim and the knuckle spindle are fixedly connected through the bolts. The front axle bearing preload adjustment assembly for a large-scale mine dumper has the advantages that: the spacer shim is ring-shaped closing structure and has a thickness of 0.2mm and the ability for accurately determine the magnitude of the preload of the bolts; when the spacer shim is abraded, the bolts can be screwed out so as to separate the bearing positioning plate and the knuckle spindle and to help operators perform maintenance or cleaning work conveniently, thus improving the work efficiency, reducing the maintenance time for the large-scale mine dumper; and the structure has simple structure and is easy to produce and exchange, and is convenient for operation, and has high preload accuracy.
Description
Technical field
The utility model relates to a kind of bearing preload adjustment assembly, specifically is a kind of large-scale mine dumping car propons bearing preload adjustment assembly, belongs to technical field of engineering machinery.
Background technology
Female cone coro bearng preload is to realize through the combination thickness that changes bearing cap shim between two bearings, reduces the thickness of compound gasket, and predetermincd tension increases, otherwise reduces.Fewer when the thickness of compound gasket, perhaps wearing and tearing are relatively serious and cause gap ratio hour, can influence the positional parameter of vehicle front-wheel, promptly cause hard steering, hair fastener, influence the steering safety property of automobile.Common bearing preload method of adjustment; The afterbody of general steering swivel is a helicitic texture, uses the single nut of purpose made to be screwed on the steering swivel tailing screw flight, and nut compresses the bearing locating plate through pad; Reach the purpose of adjust a bearing preload; This method complicated operation, the preload pressure precision is low, is unfavorable for replacing and the maintenance of quarry tipper of the bearing shim of large-scale mine dumping car propons.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of large-scale mine dumping car propons bearing preload adjustment assembly, has simple to operate, characteristics such as replacing is easy, preload pressure precision height.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of large-scale mine dumping car propons bearing preload adjustment assembly; Comprise bearing locating plate, bolt, steering swivel main shaft and bearing cap shim, also comprise bolt, and the depth survey hole that is opened in two symmetrical distributions on the bearing locating plate; Bearing cap shim places between bearing locating plate and the steering swivel main shaft, and bearing locating plate, bearing cap shim and steering swivel main shaft are connected through the bolt that is uniformly distributed with at circumferencial direction;
Further, bearing cap shim is an annulus dress closing structure, and thickness is 0.2mm.
The beneficial effect of the utility model is: bearing cap shim is an annulus dress closing structure, and thickness is 0.2mm, can accurately confirm the size of bolt pretightening; Be opened in the depth survey hole on the bearing locating plate, be used for the measurement of bearing space, according to measuring the gap of coming out; Decide the usage quantity of bearing cap shim, avoided the error of range estimation, the maintainer can judge the usage quantity of bearing cap shim rapidly and accurately; Save time, increase work efficiency; After the pad wearing and tearing; Can screw out bolt come; The bearing locating plate is separated with the steering swivel main shaft, and operating personal just can keep in repair or cleaning work more easily, has improved work efficiency; Shortened the maintenance time of large-scale mine dumping car, this apparatus structure is simple, be easy to make, easy to operate, change easily, the preload pressure precision is high.
Description of drawings
Fig. 1 is the utility model integral structure scheme drawing;
Fig. 2 is the local enlarged diagram of the utility model;
Fig. 3 is the utility model bearing locating plate intention;
Fig. 4 is a bearing cap shim scheme drawing in the utility model.
Among the figure: 1, wheel hub, 2, the bearing locating plate, 21, the depth survey hole, 3, bolt, 4, bearing cap shim, 5, the steering swivel main shaft.
The specific embodiment
To combine accompanying drawing and embodiment that the utility model is described further below.
As depicted in figs. 1 and 2, a kind of large-scale mine dumping car propons bearing preload adjustment assembly is by bearing locating plate 2; Bolt 3; Steering swivel main shaft 5 and bearing cap shim 4, bolt 3, and depth survey hole 21 compositions that are opened in two symmetrical distributions on the bearing locating plate 2; Bearing cap shim 4 places between bearing locating plate 2 and the steering swivel main shaft 5, and bearing locating plate 2, bearing cap shim 4 and steering swivel main shaft 5 are captiveed joint through the bolt 3 that is uniformly distributed with at circumferencial direction;
Bearing cap shim 4 is annulus dress closing structure, and thickness has only 0.2mm, can accurately confirm the size of bolt 3 predetermincd tensions.
The depth survey hole 21 of two symmetrical distributions on the bearing locating plate is used for the measurement of bearing space, according to measuring the gap of coming out, decides the usage quantity of bearing cap shim 4.
At first, do not put bearing cap shim 4 bearing locating plate 2 is installed, make the gauge embossed marks outwardly, hold-down bolt 3 is screwed onto 136Nm with all bolts, and wheel hub 1 is rotated minimum 3 circles; Moment of torsion is increased to 339Nm, and wheel hub 1 is rotated minimum 3 circles;
Then, 8 bolts 3 are all unclamped, wheel hub 1 is rotated minimum 3 circles; Select 1 to paint sign with the contiguous bolt 3 in 1 depth survey hole wherein and with it; Confirm and lucky bolt 3 positions that become 180 ° of the bolt of japanning 3, and it is painted sign, two bolts 3 all are screwed to 149Nm;
Secondly, two same bolts 3 are screwed to 149Nm, wheel hub 1 is rotated minimum 3 circles; Again 4 same bolts 3 are screwed to 149Nm; Again through 2 depth survey holes, with micro-depth gauge measure and record from the surface of bearing locating plate 2 to the degree of depth of steering swivel main shaft 5 ends; With above-mentioned 2 measurement size additions that measure, and with sum divided by 2 to obtain the average depth size; Deduct bearing locating plate 2 surfaces in the average depth size and go up the size of impression, confirm bearing cap shim 4 assemblies that need; Bearing cap shim 4 assemblies after confirming are installed in the 0.025mm scope.
At last, demounting bolt 3 and bearing locating plate 2 pad 4 assemblies are installed, and installation shaft are held locating plate 2 again; When rotating wheel hub 1, several times increase continuously moment of torsion, alternately bolt 3 are screwed to about 500Nm, and use diameter to connect locking in twos as the steel wire of 6mm on bolt 3.
After bearing cap shim 4 wearing and tearing, can screw out bolt 3 come, bearing locating plate 2 is separated with steering swivel main shaft 5, operating personal just can keep in repair or cleaning work more easily, has improved work efficiency, has shortened the maintenance time of large-scale mine dumping car.
