Abstract
The invention discloses an aviation knuckle bearing design method. The aviation knuckle bearing design method comprises the steps that firstly, a stainless steel material is selected for manufacturing a knuckle bearing according to the use environment requirement of the knuckle bearing; secondly, the matching size of an inner ring and an outer ring of the knuckle bearing is designed to be in clearance fit according to the use load requirement of the knuckle bearing; and thirdly, the outer surface of the inner ring of the knuckle bearing is coated according to the lubricity requirement when the knuckle bearing is used. According to the aviation knuckle bearing design method, the knuckle bearing is made of stainless steel 9Cr18 so that the requirement of the salt-spray environment test of the knuckle bearing can be met, and the bearing corrosion problem is solved; the matching clearance of the inner ring and the outer ring of the bearing is one third of a clearance specified by a design handbook, and the bearing capacity of the bearing can be improved; the outer surface of the inner ring is coated with silver, so that flexibility is improved when the bearing is used, and the bearing plays a role in assisting in lubrication on the conditions of high intensity and poor lubrication.
Description
Technical field

Background technique
Bearing is a kind of critical function part, at all kinds of engineering goods, as very general in application in the equipment (equipment) such as the traffic tool such as lathe, train, motor, aircraft, it is as the function component of transmitted load and motion in engineering goods, equipment or equipment, be described as in " joint of industry ", have very important effect.Aircraft bearing is typical precision optical machinery product, and its technical merit is the reflection of National Industrial comprehensive technical level.In national defence, aircraft bearing is the important auxiliary equipment of all weaponrys such as Aeronautics and Astronautics, weapons, naval vessel, nuclear industry; In civilian industry field, bearing is the moving element that generally needs of the national important equipment manufacturing industry such as boats and ships, machinery, automobile, bullet train, wind-powered electricity generation especially.
Certain aircraft proposes following usage requirement to joint shaft bearing: size is standard external dimensions bearing, requires that the maximum load in the unit area of bearing when repeating loading 3000 times is 150MPa; Corrosion-resistant, in the 96h salt mist environment meeting GJB150.11A, the defect such as non-corroding point, hole exists, aviation body joint shaft bearing that is that market is sold or that generally apply, its material is generally manufactured by GCr15 Bearing Steel, and bearing capacity and corrosion resistance all do not meet usage requirement; Require that bearing is lightweight, in the longevity same with aircraft, rubbing surface hardness is high, wear-resistant simultaneously, rotates flexible etc.
Summary of the invention
Problems such as the object of this invention is to provide a kind of For The Spherical Plain Bearing design method, current joint shaft bearing bearing load is little, Environmental Conditions is harsh in order to solve, lubrication is not smooth.
For achieving the above object, the technical solution used in the present invention is: a kind of For The Spherical Plain Bearing design method, is characterized in that: comprise
Step one: according to the requirement of joint shaft bearing Environmental Conditions, select stainless steel material manufacture;
Step 2: according to the requirement of joint shaft bearing maneuvering load, design joint shaft bearing Internal and external cycle fit dimension is Spielpassung;
Step 3: lubricity requirement when using according to joint shaft bearing, carries out coating at the rubbing surface of joint shaft bearing.
Further, that stainless steel material described in step 1 is selected is 9Cr18.
Further, gap described in step 2 is 1/3 of the gap size that design bearing handbook specifies.
Further, what coating described in step 3 was selected is silver-plated mode.
A kind of For The Spherical Plain Bearing design method of the present invention, adopts stainless steel 9Cr18 to manufacture and can meet joint shaft bearing salt mist environmental test, solve bearing corrosion problem; Bearing enclose matching gap adopts 1/3 of design handbook specified gap, can improve the bearing capacity of bearing; Adopt silver-plated mode at inner ring outer surface, improve flexibility when bearing uses, bearing can also be made when high strength, insufficient lubrication to play the effect of lubrication assistant.
Accompanying drawing explanation
Accompanying drawing to be herein merged in specification and to form the part of this specification, shows embodiment according to the invention, and is used from specification one and explains principle of the present invention.
Fig. 1 is the flow chart of For The Spherical Plain Bearing design method according to an embodiment of the invention.
Embodiment
For making object of the invention process, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is further described in more detail.In the accompanying drawings, same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Described embodiment is the present invention's part embodiment, instead of whole embodiments.Be exemplary type below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creation type work prerequisite, belong to the scope of protection of the invention.Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
In describing the invention; it will be appreciated that; term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear", "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " etc. instruction orientation or position relationship be based on orientation shown in the drawings or position relationship; be only the present invention for convenience of description and simplified characterization; instead of instruction or imply indication device or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limiting the scope of the invention.
As shown in Figure 1, a kind of For The Spherical Plain Bearing design method, comprising:
The first, select stainless steel material manufacture:
This stainless steel body bearing is corrosion resistant products, can apply under corrosive environment, there is not corrosion hole point: general, the material of bearing adopts Bearing Steel, the static strength under general application can be met, fatigue resistance and life requirements, but this material corrosion resistance is poor, namely red rust is there is less than 10h salt spray test, and the For The Spherical Plain Bearing of this Project design and application has selected stainless steel 9Cr18 material, both ensure that bearing static strength, dynamic load and life-span, study through design and processes, solve again bearing corrosion problem, verify that corrosion point does not appear in this material bearing after 96h through salt spray test, corrosion hole etc.,
The second, this bearing enclose adopts small―gap suture to coordinate, and matching gap is about 1/3 of design handbook specified gap, improves surface of contact by small―gap suture, significantly can improve bearing load carrying capacity, and the load that small―gap suture bears is 1.25 times of the civilian bearing of same dimension.During experiment, the maximum load in the unit area of bearing is 150MPa, and repeats loading No. 3000 bearings and can't harm bad;
