Abstract
The utility model relates to a bearing spacer is used in installation of passenger train transaxle wheel hub bearing, including spacer body and dismantlement step, the spacer body be the thin cylinder structure, the one end of spacer body inwards is provided with the dismantlement step. The utility model relates to an opening structure of present bearing spacer has been cancelled to new bearing spacer, with the one end of bearing spacer to the internal upsetting, at its inside step that forms, realize the dismantlement of bearing spacer through the step, simultaneously, when processing bearing spacer, lathe centre gripping thickening position increases the intensity of bearing spacer, the difficult centre gripping that takes place is out of shape to carrying high yield, reducing the production of waste product, it is extravagant to reduce the unnecessary raw and other materials, reduction in production cost.
Description
technical field:
The utility model relates to passenger vehicle parts technical field, is specifically related to a kind of passenger vehicle drive axle hub bearing installation bearing spacer.
background technology:
As shown in Figure 1, the scheme of installation of existing passenger vehicle drive axle hub bearing, as seen from Figure 1, fixedly realizing by arranging bearing spacer 103 between hub bearing outer ring 101 and semiaxis 102 end face of hub bearing outer ring 101, existing bearing spacer 103 as shown in Figure 2, existing bearing spacer 103 is thin-walled cylindrical workpiece, and the side of the close hub bearing of thin circular cylinder is provided with the gap 104 of dismounting, and gap 104 is arranged along bearing spacer 103 circumference.Bearing spacer 103 first need process the surfaces externally and internally of thin circular cylinder adding man-hour, and requirement on machining accuracy is high, and because of thin-wall construction, easily cause thin-walled to be out of shape when adding holding workpiece in man-hour, reject rate is high; After thin circular cylinder machines, also to process the gap 104 of four dismountings in addition, cause reject rate to raise further.
utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of passenger vehicle drive axle hub bearing installation bearing spacer, it is a kind of new bearing spacer of design, eliminate the gap structure of existing bearing spacer, one end of bearing spacer is inwardly thickeied, form step therein, the dismounting of bearing spacer is realized by step, simultaneously, when machining bearing spacer, lathe clamping thickeies position, increase the intensity of bearing spacer, not easily there is clamping distortion, thus raising yield rate, the generation of reducing the number of rejects and seconds, reduce unnecessary waste of raw materials, reduce productive costs.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of passenger vehicle drive axle hub bearing is installed and is used bearing spacer, wherein: comprise spacer body and dismounting step, described spacer body is thin-wall tubular structure, and one end of spacer body is inwardly provided with dismounting step.
Further, the thickness being provided with one end of dismounting step of described spacer body is more than or equal to the twice of its other end thickness.
Further, the width of described dismounting step is more than or equal to 1/5 of spacer body width.
The beneficial effects of the utility model are:
1, the utility model is a kind of new bearing spacer of design, eliminates the gap structure of existing bearing spacer, is inwardly thickeied one end of bearing spacer, form step therein, realized the dismounting of bearing spacer by step, simultaneously, when machining bearing spacer, lathe clamping thickeies position, increases the intensity of bearing spacer, and clamping distortion not easily occurs, thus raising yield rate, the generation of reducing the number of rejects and seconds, reduces unnecessary waste of raw materials, reduces productive costs.
2, the utility model structure simple, easy to use, conceive novel, with low cost, simple and reliable, processing and fabricating is easy, significantly can reduce the difficulty of processing of bearing spacer, improve product design, makes again the dismounting of bearing spacer become simpler simultaneously.
accompanying drawing illustrates:
Fig. 1 is the mounting structure schematic diagram of existing passenger vehicle drive axle hub bearing;
Fig. 2 is the structural representation of existing bearing spacer;
Fig. 3 is structural representation of the present utility model.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 3, a kind of passenger vehicle drive axle hub bearing installation bearing spacer, comprise spacer body 1 and dismounting step 2, described spacer body 1 is thin-wall tubular structure, and one end of spacer body 1 is inwardly provided with dismounting step 2.The thickness being provided with one end of dismounting step 2 of described spacer body 1 is the twice of its other end thickness.The width of described dismounting step 2 is 1/5 of spacer body 1 width.
During processing the utility model, jig clamps one end being provided with dismounting step 2 of the present utility model, because the thickness of the one end being provided with dismounting step 2 obviously thickeies, improves intensity of the present utility model, clamping distortion can be avoided by actv., improve yield rate.
When needing to dismantle the utility model from drive axle hub, after being goed deep into from the endoporus of bearing spacer by withdrawing device, hook dismounting step 2 from inside, then the utility model pulls out by reinforcing.
Be noted that, above-described embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendment made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
