Abstract
The invention discloses a second motion shaft, comprising a limiting part, a first main body part and a second main body part, wherein the first main body part extends from one end of the limiting part, the second main body part extends from another end of the limiting part, and each of the first main body part and the second main body part is provided with a guide part. The guide parts are arranged on the first and second main body parts of the second motion shaft, so that when mounted, the second motion shaft can be positioned fast and exactly, and the mounting efficiency is improved.
Description
Technical field
The invention belongs to field of mechanical technique, be specifically related to a kind of gap bridge axle.
Background technique
Present common bearing can be divided into by its loading direction that can bear: radial bearing, claim radial bearing again, and bear radial load; Thrust bearing is claimed thrust-bearing again, conveniently thrust load; Radial-thrust bearing is claimed radial thrust bearing again, bears radial load and thrust load simultaneously.Though 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.
Summary of the invention
The object of the present invention is to provide the high gap bridge axle of installation efficiency.
For realizing the foregoing invention purpose; A kind of gap bridge axle provided by the invention; This gap bridge axle comprises: limited part, from first main part of said limited part one end extension, from second main part of said limited part the other end extension; Wherein, all be provided with guide portion on said first main part and second main part.
As further improvement of the present invention, said guide portion is cone table shape.
As further improvement of the present invention, comprise slug hole on said first main part.
As further improvement of the present invention, said slug hole runs through said first main part.
As further improvement of the present invention, said slug hole extends along the said first main part longitudinal direction.
As further improvement of the present invention, said slug hole is passed in the medial axis of said first main part.
As further improvement of the present invention, comprise slug hole on said second main part.
As further improvement of the present invention, said gap bridge axle surface is through quenching with Subsequent tempering.
Compared with prior art, the present invention locatees in the time of can conveniently installing through on first main part of the axle of passing a bridge and second main part, guide portion being set fast and accurately, improves installation efficiency.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing relevant of the present invention in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 be the present invention pass a bridge the axle one mode of execution structural representation.
Embodiment
Below will combine embodiment shown in the drawings to describe the present invention.But these mode of executions do not limit the present invention, 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 protection scope of the present invention.
Ginseng Fig. 1 introduces the present invention's axle embodiment of 10 of passing a bridge.In this mode of execution, this gap bridge axle 10 comprises limited part 11, first main part 12 and second main part 13.
First main part 12 extends from an end of limited part 11, and second main part 13 extends with first main part, the 12 relative the other ends on this limited part 11.In this mode of execution, the section area of limited part 11 is greater than the section area of first main part 12 and second main part 13, so to play spacing effect.First main part 12 and second main part 13 can bear radial load and thrust load.
All be provided with guide portion 14 on first limited part 11 and second limited part 11, this guide portion 14 is used to guide this first main part 12 and second main part 13 to cooperate smoothly with mounting hole.As preferred embodiment, this guide portion is cone table shape, and this is because the guide portion of cone table shape has a smooth guiding face (indicating), the effect of playing guiding that can be preferable.
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 regarded as the bad technological scheme that changes of the present invention, must belong within protection scope of the present invention.
As preferred embodiment, also include slug hole 15 on first main part 12, this slug hole 15 can reduce raw-material use for axle 10 losss of weight of passing a bridge, and reduces production costs.
Distinguishingly, this slug hole 15 runs through first main part 12, and this slug hole 15 is along the longitudinal direction extension of first main part 12.The slug hole 15 of this " long and narrow " moulding can guarantee not reduce the workpiece strength of gap bridge axle 10, ensures the quality of products.
Distinguishingly, in this mode of execution, slug hole 15 is passed in the medial axis of first main part 12, so, and the weight distribution of the axle 10 of can balance passing a bridge.
Should be understood that, in other embodiments, also can include slug hole on second main part 13 of this gap bridge axle 10.In this mode of execution, only being provided with slug hole 15 with first main part 12 is example, sets forth the present invention, and this only is the convenience in order to describe.
Distinguishingly, the surface of gap bridge axle 10 is through quenching with Subsequent tempering.So-called quenching with Subsequent tempering is promptly quenched and the comprehensive heat treatment process of high-temperature tempering; It can so that the performance of the material of the axle 10 of passing a bridge adjusted significantly; Make its intensity, plasticity and toughness all be highly improved, and, need not increase extra cost.
The invention has the beneficial effects as follows:, locate the raising installation efficiency in the time of can conveniently installing fast and accurately through on first main part 12 of the axle 10 of passing a bridge and second main part 13, guide portion 14 being set.
Be to be understood that; Though 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, and those skilled in the art should make specification as a whole; Technological scheme in each mode of execution also can form other mode of executions that it will be appreciated by those skilled in the art that through appropriate combination.
The listed a series of detailed description of preceding text only is specifying to feasibility mode of execution of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent mode of execution or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
