The forest logging chain special-shape bushing is characterized in that the body comprises an arched part; the two sides of the axial direction of the arched part are connected through an arc part; and the through hole is formed between the arc part and the arched part. Compared with the prior art, the forest logging chain special-shape bushing provided by the utility model has the advantages of good wear resistance, high strength, high toughness, corrosion resistance, high temperature resistance and the like; and meanwhile, the forest logging chain special-shape bushing meets the needs of related industries of the country, has more reasonable design, high structural strength and long service life, and conforms to the technological development trend of the current society.
Description
Technical field
The utility model belongs to the lining technical field, especially relates to a kind of forest lumbering chain abnormity lining.
Background technique
Lining: play the ring set of liner effect, be enclosed within on the axle, when liner wear, can change, reduced to a certain extent user cost.If without lining, after the wearing and tearing, replacing be part.So change into when being the replacing bushing design, just with the lining lower hardness, it become in friction pair hold mill spare.Easy to process because of it, replacement cost is low, also easily changes, so be widely used.Certainly, it has the effect of guiding etc. in addition.At present, on forest lumbering chain, generally how can use lining, it is enclosed within on the bearing pin, and volume prevents the bearing pin wearing and tearing, and all there is such defective in existing these forest lumbering chain linings: the structure that is mostly tubulose, it can satisfy usage requirement to a certain extent, but the bush structure intensity of this structure is lower, has so just virtually shortened the working life of lining, has also shortened simultaneously the working life of lumbering chain, need regular inspection and maintenance, increased user cost.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of bush of rear wheel hub [application number: 200520109377.7], this lining integral body only has one deck and utilizes the heat-resisting of nylon, oil resistant, wear-resisting, impact resistance is strong, the low characteristic of the good cost of pliability, be installed in when being used for the moment transmission on the locomotive rear-wheel hub, locomotive can be made in starting and buffering moment between the gear teeth and wheel hub can be slowed down to greatest extent when accelerating suddenly, make moment balancedly pass to rear-wheel hub, can effectively slow down the moment transmission, simultaneously can avoid separating, delamination, draw phenomenon bad and that damage, long service life, need not often change, can greatly reduce cost.Above-mentioned scheme is the working life that prolongs lining by the improvement of material, but this scheme can not be applicable to the utility model, in addition, just can be used for the utility model at last, and its working life is still shorter, affects to a certain extent workman's normal operation.
The model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of design more reasonable, and structural strength is high, the forest lumbering chain abnormity lining of long service life.
For achieving the above object, the utility model has adopted following technical proposal: Ben Senlin lumbering chain abnormity lining comprises body, has through hole at body along its axial direction, it is characterized in that, described body comprises arch portion, the axial dual-side of described arch portion links to each other by curved portions, and forms described through hole between this curved portions and the arch portion.Obviously, the utlity model has that wear resistance is good, high strength, high tenacity, the advantage such as corrosion-resistant and high temperature resistant, satisfy simultaneously national relevant industries required, it is more reasonable to design, and bush structure intensity is high, and long service life meets the trend of current social technical development.
In above-mentioned forest lumbering chain abnormity lining, described curved portions comprises the arc body of setting placed in the middle, and the axial dual-side of described arc body is connected by the axial dual-side of the first connecting body and the second connecting body and arch portion respectively.
In above-mentioned forest lumbering chain abnormity lining, the lateral cross section of described arc body is circular arc, and the protrusion direction of this arc body is opposite with the protrusion direction of arch portion.
In above-mentioned forest lumbering chain abnormity lining, the lateral cross section of described the first connecting body and the second connecting body is shape linearly all.
In above-mentioned forest lumbering chain abnormity lining, described arc body radius is greater than the radius of described arch portion.
In above-mentioned forest lumbering chain abnormity lining, described body surface hardness is greater than its core hardness.
In above-mentioned forest lumbering chain abnormity lining, described body is made by metallic material.Metallic material comprises high-intensity alloyed steel etc. material.
Compared with prior art, the advantage of this forest lumbering chain abnormity lining is: have that wear resistance is good, high strength, high tenacity, an advantage such as corrosion-resistant and high temperature resistant, satisfy simultaneously national relevant industries required, it is more reasonable to design, bush structure intensity is high, long service life meets the trend of current social technical development.
