Description
Technical field
The utility model relates to technical field of aircraft structure design, in particular to a kind of outer shroud fluting joint shaft bearing.
Background technique
As everyone knows, bearing is a kind of important spare part in contemporary machinery.Its major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into rolling bearing and the large class of sliding bearing two.Wherein rolling bearing standardization, seriation, but its radial dimension, vibration & noise is comparatively large compared with sliding bearing, and price is also higher.Sliding bearing is the bearing worked under sliding friction.Sliding bearing stable working, reliable, noiseless.Under liquid lubrication condition, the undeveloped life of the lubricated oil content of slidingsurface directly contacts, and can also greatly reduce frictional loss and surface abrasion, oil film also has certain vibration absorption ability.But starting friction resistance is larger.Axle is called axle journal by the part that bearing supports, and the part matched with axle journal is called bearing shell.In order to improve the frictional property on bearing shell surface and the friction reducing material of casting on the surface is called bearing bush within it.The material of bearing shell and bearing bush is referred to as material for sliding bearing.Sliding bearing application is generally under low-speed heave-load working condition.It is domestic that what generally adopt for sliding bearing abrasion is repair welding, the edge method such as axle sleeve, scutching point, but when the material of axle is No. 45 steel (quenching with Subsequent tempering), if only adopt built-up welding process, then can produce welding interior stress, at heavy load or when running up, the phenomenon of crackle and even fracture may be occurred at shaft shoulder place, if employing stress relief annealing, then be difficult to operation, and the process-cycle is long, recondition expense is high; When the material of axle is HT200, adopt cast iron weldering also undesirable.The enterprise that some maintenance techniques are higher can adopt Brush Plating, laser beam welding, the differential of the arc to weld even cold welding etc., and these maintenance techniques often need higher requirement and high expense.Joint shaft bearing is sliding bearing, joint shaft bearing many employings extrusion pressing type structure in the middle of prior art, and its technique is simple, but outer race is softer, and bearing capacity is low, is easy to wearing and tearing, and not easily changes.
The technical problem needing now solution badly how to design a kind of bearing, and this bearing can overcome the adverse effect that sliding bearing in above-mentioned prior art is manufactured and produced in using process.
