Description
Technical field
The present invention relates to a kind of swelling pressure of the liner bonding solidification of bearing mnanufacture field, especially self-lubricating knuckle bearing
Label apparatus.
Background technology
Self-lubricating knuckle bearing is a kind of oscillating bearing of the specific form without the need for supplemental lubrication agent, and its structure is by bearing
Circle, bearing outer ring, three part of fabric liner composition.Textile type self-lubricating knuckle bearing is due to having a structure which simple, volume
Little, bearing capacity is big, coefficient of friction is little, impact resistance, corrosion-resistant, life-span length, reduce vibration, the advantages of Applicable temperature scope is wide, and
And with freedom from repairs and can need not add lubricant in the course of the work, it is widely used in engineering machinery, truck, water conservancy and sets
Apply, the aspect such as military project machinery.China carries out for the research work of self-lubricating knuckle bearing must be than later, external blockade on new techniques
Progress is allowed for secrecy more slow.In view of self-lubricating knuckle bearing modern industry especially Aero-Space etc. some
Indispensable status in leading-edge field, the research for self-lubricating knuckle bearing are extremely urgent.Textile type self-lubricating joint shaft
Holding lubrication principle is：Fabric liner is bonded in bearing outer ring Internal Spherical Surface, constitutes spherical pair with bearing inner race spherical outside surface.During work,
Fabric liner forms the transfer membrane of low shear strength between friction pair, plays self-lubricating function, and its performance directly decides certainly
The life-span of lubricating joint bearing.
The bonding of the selflubricating liner of self-lubricating knuckle bearing and curing process are one of key technologies of bearing mnanufacture.Work
Skill process is：Using certain bonding agent, the liner of dipping solidification is pasted into outer ring Internal Spherical Surface, keep serving as a contrast by sticker
Pad bears certain pressure, is then placed in hot environment, the control of Jing times and temperature, realizes solidification process.By above-mentioned mistake
In bonding with curing process, many factors can all have influence on liner bonding with solidification quality to Cheng Kezhi.Specific influence factor
Such as：The control of the technological parameters such as the selection of bonding agent, technique for sticking temperature, time, power, bonding action implementation method, bonding are solid
Makeup put and bonding action implementation method and device effectiveness and reliability etc..Bonding and the direct shadow of the quality of curing process
The performance to self-lubricating knuckle bearing is rung, so the research of solidification technique for sticking process is imperative.With regard to bonding agent, solidification work
The technical research of skill parameter is relatively more, but the equipment and technology that selflubricating liner is bonded in the outer ring Internal Spherical Surface of oscillating bearing is ground
Study carefully less, especially for the bearing of reduced size, the technology application that the action bonding with curing process of its bonding is realized with device
Research is even more and tends to blank, does not have disclosed patent to be related to the field with document.
The content of the invention
