Embodiment
To the bearing involved by the utility model, closing-up device is installed below in conjunction with accompanying drawing to be described in further details.
As shown in Fig. 1,2,3,4,5,6, bearing of the present utility model is installed closing-up device and is comprised the body of rod 1, Cock screw 2, plus screw 4, apotting spindle 5, cover plate 6 and steel ball 7.
The body of rod 1 adopts common Morse taper shank, and material is tool carbon steel, Quenching Treatment.The body of rod 1 one end end face offers cylindrical recesses, and cylindrical recesses internal fixtion is provided with apotting spindle 5.The length of usual apotting spindle 5 is greater than the cylindrical recesses degree of depth, and the segment outer radius that apotting spindle 5 stretches out matches, for the body of rod 1 is fixedly mounted on bearing inner race with needing the internal diameter of the bearing closed up.
One end that the body of rod 1 has cylindrical recesses also offers radial screw, is communicated with cylindrical recesses, is provided with Cock screw 2 in screw, can be undertaken fastening by the apotting spindle 5 in cylindrical recesses, prevent from coming off by Cock screw 2.
Cover plate 6 is rounded, is fixedly installed on offering on one end end face of cylindrical recesses of the body of rod 1.Cover plate 6 offers multiple through hole 8, multiple through hole 8 is along circular distribution, wherein, forms the unequal donut of at least diameter, is symmetrically arranged with at least two through holes 8 within the scope of each annulus.
Preferably, in the present embodiment, above-mentioned annulus is 3, and is evenly provided with 3 through holes 8 within the scope of the ring-type of each annulus.The size of annulus external diameter is usually relevant with needing the annular groove size of the part attachment face installed.Further, the excircle dimension of the apotting spindle 5 of three kinds of specifications also can be processed according to the brearing bore of different size.
Bearing of the present utility model installs closing-up device by selecting 3 through holes 8 on different-diameter and changing corresponding apotting spindle 5, may be used for the bearing assemble of at least three kinds of specifications.
On cover plate 6 and the body of rod 1, corresponding position offers screw, and the plus screw 4 by matching with screw between cover plate 6 and the body of rod 1 is fixed.
The cross section of through hole 8 is tapered, and bigger diameter end is towards the described body of rod 1.Steel ball 7 is provided with in through hole 8.The diameter of steel ball 7 is greater than the thickness of cover plate 6, and steel ball 7 can roll in through hole 8, for roll extrusion part annular groove, makes it produce distortion, reaches bearings mounted object.Namely closing-up device coordinates three corresponding positions steel ball 7 by the apotting spindle 5 of three kinds of specifications installed by bearing of the present utility model, adapts to the bearing assemble of at least three kinds of specifications.
In addition, bearing installation closing-up device of the present utility model can also comprise planchet plate 3.The material of planchet plate 3 can adopt high tensile steel, has very high hardness and wear resistance after Quenching Treatment.The one side of planchet plate 3 is fixedly connected with one end end face of the body of rod 1, and cover plate 6 is fixedly installed on the another side of planchet plate 3.Planchet plate 3 is mainly used in padding steel ball 7, steel ball 7 and the body of rod 1 end face is separated, and reduces the wearing and tearing of the body of rod 1.
Further, on cover plate 6, planchet plate 3 and the body of rod 1, corresponding position offers screw, cover plate 6, is fixed by the plus screw 4 matched with screw between planchet plate 3 and the body of rod 1.
Closing-up device installed by bearing of the present utility model, by the method for integrated combination, the kind of closing-up device is simplified, reach the bearing that a frock can assemble plurality of specifications, effectively reduce the use of large quantities of steel ball closing-up device, make applicability strong, applied range, and improve efficiency and the assembly quality thereof of bearing installation.In addition, by increasing planchet 3, effectively extending the working life of such closing-up device, such closing-up device can be repeatedly used.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the original prerequisite of the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
