The track roller and the guide wheel comprise a roller shaft (1) and two half roller bodies (2 and 3) sleeved on the roller shaft (1), wherein a shaft sleeve component (4) is arranged inside the inner holes of the half roller bodies; and the track roller and the guide wheel are characterized in that the shaft sleeve component (4) is tightly fixed with one of the two half roller bodies on the outer side in a matched manner, the other half roller body is in interference fit with the shaft sleeve component (4), and a check ring (5) axially limiting the roller shaft is arranged on the outer side of the shaft sleeve component. The track roller and the guide wheel simplify the roller structure of a tracked mechanical chassis component, greatly improve the assembly quality and efficiency of the roller and the production efficiency of processing and manufacturing roller parts, reduce the manufacturing cost, improve the quality of roller products, and can be applicable for the chassis components of engineering machinery, construction machinery, small and medium agricultural machinery and small and medium special machinery.
Description
Technical field
The invention belongs to the caterpillar machinery chassis member design field in the technical field of engineering machinery, be specifically related to caterpillar wheel and guide wheel in a kind of caterpillar mechanical travelling mechanism.
Background technology
The tracked construction equipment running gear is divided into the track unit of track unit that caterpillar wheel is arranged and no caterpillar wheel according to having or not of caterpillar wheel.Because be mainly cliding friction during the walking of the track unit of no caterpillar wheel, it is comparatively serious to wear and tear, field of application is less.There is the track unit of caterpillar wheel mainly to form, i.e. crawler belt, drive wheel, guide wheel, track carrying wheel, caterpillar wheel and tightening device, track frame etc. by " four-wheel one band ".Drive wheel produces relay in pilled-in selvedge, driving section and the ground connection section of crawler belt during operation, owing between crawler belt under the caterpillar wheel and ground enough adhesive ability is arranged, stop pulling out of crawler belt, force drive wheel scrolling crawler belt, track adjusting wheel is routed to crawler belt on the ground again, thereby makes tracked construction equipment borrow the load-bearing of caterpillar wheel along crawler belt rail ahead running.Article two, crawler belt is driven by different actuating device (as fluid pressure drive device) respectively, realizes turning on the spot when the actuating device driving direction is opposite; When only a side drive device drives, realize turning to around a side crawler belt.Guide wheel, caterpillar wheel can abbreviate roller as.
The tracked construction equipment running gear is because bearing surface area is big, ground connection is littler than the Asia, the traction adhesion value is good, and being difficult for skidding is that other running gears can not be compared; In a lot of industries application is arranged all.Because its friction force is a friction of rolling when having the track unit of caterpillar wheel to walk, friction force is little, so its duty ratio is bigger, can apply to the walking of big machinery and equipment.Caterpillar wheel is the weight that is used for supporting caterpillar machinery, and rolls on the chain rail of crawler belt, and machinery is travelled along the chain rail, and it also is used for the clamping crawler belt, makes it not along laterally slippage, and forces crawler belt slippage on the ground when turning.Caterpillar wheel is everlasting and is worked in the muddy water dust, and bears intense impact, and service conditions is very poor, requires therefore that its sealing is reliable, the caterpillar wheel body is wear-resisting.
The keystone configuration of roller comprises that associated components such as roller body, roller shaft, sleeve assembly, first seal ring, second seal ring, roller shaft exterior and interior cover constitute.Materials such as the general 40Mn2 of roller body material, main technique casting or forging, machine up is heat-treated then, and the hardness after wheel surface is quenched will reach about HRC52, to increase the resistance to abrasion of wheel surface.The requirement on machining accuracy of roller shaft generally is to need numerically-controlled machine tool to process just can reach requirement than higher.Material is more with 45 steel, also will carry out quenching heat treatment after the processing, and hardness reaches about HRC54.Roller can be divided into monolateral roller and bilateral roller; Excavating machine is with roller and bulldozer roller.
Fig. 1 is common monolateral roller, the sheathed two roller body halfbodies 2,3 in roller shaft 1 outside of this roller, in the described roller body endoporus sleeve assembly 4 is set, thereby described sleeve assembly 4 is by fixing axial limiting roller body and sleeve assemblies with the roller body bolt 8 in the outside.In order to lock roller body and sleeve assembly, when bolt connected, pad was established pad 9 on the bolt.The inside and outside lid 6,7 of the sheathed roller of captiveing joint with sleeve assembly 4 in described roller shaft both sides, inside and outside lid 6,7 of described roller and 4 of sleeve assemblies are provided with float grease seal 81 sealings.Described roller shaft 1 two ends are provided with side grain, and trapezoidal groove is set on one of them, are provided with in the described trapezoidal groove and prevent the axially movable flat key of roller shaft.Inside and outside lid 6,7 of roller and 1 of roller shaft are provided with 82 sealings of first O-ring seals; 4 of roller body and sleeve assemblies are provided with 83 sealings of second O-ring seals.Wherein sleeve assembly comprises the iron cover and is arranged on the interior lining of iron cover, for fastening with roller body, usually is connected with iron cover flange in the iron cover outside.Common roller adopts the iron cover with roller body endoporus close-fitting and by bolt in caterpillar machinery chassis member, can limit the axial string momentum of roller shaft like this, yet such structure packaging efficiency is low, and it is many to take up room, and cost is than higher.The present invention comes therefrom.
Summary of the invention
Problems such as the object of the invention is to provide the roller in a kind of caterpillar mechanical travelling mechanism, and it is low to have solved roller packaging efficiency of the prior art, and it is many to take up room, and cost is higher.
In order to solve these problems of the prior art, technical scheme provided by the invention is:
Caterpillar wheel in a kind of caterpillar mechanical travelling mechanism, comprise roller shaft and the two roller body halfbodies that are set on the roller shaft, be provided with in the described roller body halfbody endoporus and the fixing sleeve assembly of roller body, one of the two roller body halfbodies close-fitting that it is characterized in that the described sleeve assembly and the outside is fixed, another roller body halfbody and sleeve assembly interference fit, and the back-up ring of described sleeve assembly arranged outside axial limiting roller shaft.
