Summary of the invention:
Wear-resisting functions based on biological surface is not only relevant with biomaterial, and the relevant thought of geometry surface that in the abrasive wear process, forms with biological surface geometrical construction or biomaterial, the objective of the invention is to: start with from changing the wearout parts surface geometry, solution improves the wear resistance problem of bulk material and its motion surface of contact and a kind of rib type bionic abrasion-proof structure surface is provided.
Realize that the technological scheme accompanying drawings that above-mentioned purpose of the present invention adopted is as follows:
Realize that the technological scheme that above-mentioned purpose of the present invention adopted is: the scale surface based on soil burrowing animal pangolin has anti abrasive geometrical construction feature, analyze and dimensional measurement according to optimizing, finally extract a kind of lip-deep rib type bionic abrasion-proof structure surface of mechanical part that is arranged at the bulk material contact, its structure outline is the half period curve of sine function: y=asin (bx+c), wherein: the a-amplitude, the b-frequency, the c-initial phase, 0＜a≤12mm, 0≤bx-c≤π, 0≤x≤20mm, the rib structure at the distribute spacing of contact surface is: 0＜L＜30mm.
The contact surface at said rib and its place can be structure as a whole, and also can make monomer respectively and link together with contact surface.
The rib type structure need be carried out concrete assignment in the Sliding velocity on surface and the mechanism size of mechanism or parts according to material size and material, can obtain anti abrasive geometric profile.The a series of rib type structure pitch (0＜L＜30mm that determines according to the method described above that has is set up on the surface that existing equipment or member contact with material.) the ribbed shape structure, can obtain rib type bionic abrasion-proof structure surface.Rib spacing L value can be determined and adjusts at the relative sliding velocity on surface etc. according to concrete bulk material size and material.Producing this surface need be according to the material of machine or parts, and concrete characteristics such as structure and use are carried out determining of production technology.As: machining, molding and forming, technologies such as compression molding.The rib type structure is set from the teeth outwards, and rib can be structure as a whole with the surface, also can make monomer respectively and be connected to together.As utilize screw to connect, and can regularly replace like this, easy to maintenance.
The present invention has following technique effect:
Utilize the rib self structure to change the field of flow of bulk material, near wall region shear layer material density is reduced, reduced the touch opportunity of prose style free from parallelism particle at contact surface; Simultaneously, can make the partial material particle change into rolling condition, thereby alleviate the wearing and tearing of material contact surface by the sliding mode of original and surface of contact.Consult accompanying drawing 3: it is 35 when spending for the bulk material angle of attack, and bulk material contacts and the motion state schematic representation with bionical rib type body structure surface.It has the wear resistance that improves contact component, the effect that prolongs its working life.This structure wearability is compared with the wear resistance of smooth surface, can improve 20.71%～51.92%.
