Abstract
The utility model relates to oil chain transmission components of engineering machines, in particular to a chain joint of an oil chain. The chain joint of the oil chain comprises a cylindrical chain joint body, and a through hole is formed in the chain joint body. The chain joint of the oil chain is characterized in that connecting portions contracted inwards are formed at the two ends of the chain joint body, one end, corresponding to the connecting portions, of the two ends of the through hole of the chain joint body forms a flaring end, and the diameter of the flaring end of the through hole is 0.04-0.07mm larger than that of the middle section of the through hole. The chain joint of the oil chain is simple in structure and convenient to produce, the chain joint is in interference fit with chain links through the connecting portions formed at the two ends of the chain joint body, the abrasion between the chain joint and the chain links is greatly reduced, shock resisting performance is good, and therefore the service life of the oil chain is prolonged, and the chain joint of the oil chain can be widely applied to the oil chains of excavators, bulldozers and other engineering machines.
Description
Technical field
The utility model relates to engineering machinery oil chain transmission part, is specifically related to a kind of oily chain chain and leads to.
Background technique
Existing, engineering mechanical device is as all needed to use oily chain on excavator, loader, and oily chain is connected to form by a plurality of chain links, and chain link is provided with that chain is logical, and when stressed, the easy long-living be full of cracks of chain go side section is even ruptured, and while using noise large, easily damage.For addressing the above problem, notice of authorization number is: it is logical that the utility model patent of CN2769144Y discloses a kind of chain, and it is characterized in that: there is packing ring at the two ends that chain is logical.This kind of chain all crossed packing ring and eliminated chain go side section crack performance, reduces wearing and tearing, improves anti-seismic performance, but this kind of chain leads to complex structure, is not easy to install, and wear washer easily weares and teares, after the wear washer wearing and tearing, also need more, as not timely replacing also may cause occurring contingency, there is potential safety hazard.
The model utility content
For overcoming deficiency of the prior art, the utility model provides that a kind of anti-seismic performance is good, the little oily chain chain that weares and teares is logical, comprise that a cylindricality chain leads to body, be provided with a through hole in the logical body of this chain, it is characterized in that: the logical body of described chain two ends form the through hole two ends one section formation flared end corresponding with joint of joint and the logical body of chain of inside contraction, and this through hole flared end diameter is than the large 0.04-0.07mm of intermediate section diameter.
Further, the diameter of the logical body of chain is 68-70mm, and the diameter of the logical body of chain two ends joint is 65-67mm, and in the logical body of chain, the diameter of through hole is 43-45mm.
Further, the joint outer of the logical body of chain is provided with chamfering.
From above-mentioned to description of the present utility model, it is simple in structure, convenient for production that the oily chain chain that the utility model provides leads to, by being formed at the logical body of chain two ends joint, with the chain link interference, be connected, it is good to greatly reduce with wearing and tearing, the anti-seismic performance of chain internode, thereby extended the working life of oily chain, be widely used on the oily chain of the engineering machinery such as excavator, bulldozer.
The accompanying drawing explanation
Fig. 1 is the logical structural representation of the utility model oil chain chain.
Embodiment
Below by embodiment, the utility model will be further described.
Shown in Fig. 1, a kind of oily chain chain is logical, comprises that a cylindricality chain leads to body 1, in the logical body 1 of chain, is provided with a through hole 2.The logical body of chain 1 two ends form the joint 11 of inside contraction, and joint 11 outers are provided with chamfering 111; One section formation flared end that through hole 2 two ends of the logical body 1 of chain are corresponding with joint 11, this through hole flared end diameter is than the large 0.04-0.07mm of intermediate section diameter.The diameter of the logical body 1 of this specific embodiment medium chain is 68-70mm, and the diameter of the logical body of chain two ends joint is 65-67mm, and in the logical body of chain, the diameter of through hole is 43-45mm; The diameter of the logical body 1 of chain of the present utility model is 69mm, and the diameter of the logical body of chain two ends joint is 67mm, and in the logical body of chain, the diameter of through hole is 45mm.The flared end diameter is than the large 0.05mm of intermediate section diameter.
Above are only embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
Claims (3)
