Abstract
The utility model discloses a bridge shaft which comprises a limiting portion, a first main body portion extending from one end of the limiting portion, and a second main body portion extending from the other end of the limiting portion, wherein the first main body portion and the second main body portion are both provided with guiding portions. By arranging the guiding portions on the first main body portion and the second main body portion of the bridge shaft, the bridge shaft can be installed conveniently and located quickly and accurately, and installation efficiency can be improved.
Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of bridge shaft.
Background technique
Present common bearing can be divided into by its loading direction that can bear: radial bearing, claim again radial bearing, and bear radial load; Thrust bearing claims again thrust-bearing, conveniently thrust load; Radial-thrust bearing claims again radial thrust bearing, bears simultaneously radial load and thrust load.Although radial-thrust bearing can bear radial load and thrust load simultaneously, this kind bearing is comparatively complicated when mounted usually, can not be installed into quickly and accurately in the workpiece, and efficient is lower.
The model utility content
The bridge shaft that provides installation efficiency high is provided the purpose of this utility model.
For realizing above-mentioned model utility purpose, a kind of bridge shaft that the utility model provides, this bridge shaft comprises: limited part, the first main part from described limited part one end extension, the second main part from described limited part the other end extension, wherein, all be provided with guide portion on described the first main part and the second main part.
As further improvement of the utility model, described guide portion is cone table shape.
As further improvement of the utility model, comprise slug hole on described the first main part.
As further improvement of the utility model, described slug hole runs through described the first main part.
As further improvement of the utility model, described slug hole extends along described the first main part longitudinal direction.
As further improvement of the utility model, described slug hole is passed in the medial axis of described the first main part.
As further improvement of the utility model, comprise slug hole on described the second main part.
As further improvement of the utility model, described bridge shaft surface is through quenching with Subsequent tempering.
Compared with prior art, the utility model arranges guide portion by the first main part and the second main part at bridge shaft, locates fast and accurately in the time of can conveniently installing, and improves installation efficiency.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model bridge shaft one mode of execution.
Embodiment
Below with reference to embodiment shown in the drawings the utility model is described in detail.But these mode of executions do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these mode of executions, method or the function all is included in the protection domain of the present utility model.
Join Fig. 1, introduce an embodiment of the utility model bridge shaft 10.In the present embodiment, this bridge shaft 10 comprises limited part 11, the first main part 12 and the second main part 13.
The first main part 12 extends from an end of limited part 11, and the second main part 13 the other end relative with the first main part 12 on this limited part 11 extends.In the present embodiment, the section area of limited part 11 is greater than the section area of the first main part 12 and the second main part 13, so to play spacing effect.The first main part 12 and the second main part 13 can bear radial load and thrust load.
All be provided with guide portion 14 on the first limited part 11 and the second limited part 11, this guide portion 14 is used for this first main part 12 of guiding and the second main part 13 cooperates smoothly with mounting hole.As preferred embodiment, this guide section is cone table shape, and this is because the guide section of cone table shape has a smooth guiding face (not indicating), the effect of playing guiding that can be better.
Should be understood that in the mode of execution of other replacements, this guide portion 14 also can be set to the halfpace shape, triangular cone table shape etc., but these all should be considered as the bad technological scheme that changes of the present utility model, must belong within the protection domain of the present utility model.
As preferred embodiment, also include slug hole 15 on the first main part 12, this slug hole 15 can reduce raw-material use for bridge shaft 10 losss of weight, reduces production costs.
Distinguishingly, this slug hole 15 runs through the first main part 12, and this slug hole 15 is along the longitudinal direction extension of the first main part 12.The slug hole 15 of this " long and narrow " moulding can guarantee not reduce the workpiece strength of bridge shaft 10, ensures the quality of products.
Distinguishingly, in the present embodiment, slug hole 15 is passed in the medial axis of the first main part 12, so, and weight distribution that can balance bridge shaft 10.
Should be understood that, in other embodiments, also can include slug hole on the second main part 13 of this bridge shaft 10.In the present embodiment, only be provided with slug hole 15 as example on the first main part 12, set forth the utility model, this only is the convenience in order to describe.
Distinguishingly, the surface of bridge shaft 10 is through quenching with Subsequent tempering.So-called quenching with Subsequent tempering is namely quenched and the Thermal Synthetic treatment process of high-temperature tempering, its can so that the performance of the material of bridge shaft 10 adjusted significantly, so that its intensity, plasticity and toughness all is highly improved, and, do not need to increase extra cost.
The beneficial effects of the utility model are: by the first main part 12 and the second main part 13 at bridge shaft 10 guide portion 14 is set, locates fast and accurately in the time of can conveniently installing, improve installation efficiency.
Be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technological scheme in each mode of execution also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description only is specifying for feasibility mode of execution of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent mode of execution or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
