Abstract
The utility model discloses a bush roller chain. The bush roller chain comprises two rows of outer links which are arranged in parallel, wherein middle links parallel to the two rows of outer links are arranged between the two rows of outer links, inner links are arranged at the both sides of each middle link and the inner sides of the outer links, the outer links, the middle links and the inner links are 8-shaped and connected together in a penetrating manner by pin shafts, a bush is arranged between the inner links and the pin shafts, a roller is sleeved to the outer surface of the bush, the pin shafts, the inner links and the outer links are arranged in a mutually staggered manner, a lock pin is arranged between every two adjacent pin shafts, and the lock pins are arranged on the outer surfaces of the outer links; and the pin shafts on the end part of the bush roller chain are connected with connection links, and connection pin shafts are connected to the outer ends of the connection links in a penetrating manner. The bush roller chain has the characteristics of being high in strength, high in accuracy, high in wear resistance and the like, as well as is high in tensile strength, long in service life, and capable of being widely used in standard chain transmission equipment.
Description
Technical field
The utility model relates to a kind of chain, is specially a kind of bush roller chain.
Background technique
Roller chain is the basic part in mechanical parts, and roller chain is normally used in the transfer (Conveying chains) of mechanical transmission of power (Transmitted chains), object, occasions such as the lifting (dragging chain) of weight and other specific uses (extraordinary chain).
Existing roller chain is all standardized products, they all meet the physical dimension of standard GB/T/T1243-2006 " short pitch precision roller chain, bushing chain, annex and sprocket wheel for transmission " regulation, in this standard, stipulated that Transmitted chains divides two series, i.e. A series and B series.In real mechanical transmission, often be subject to spatial position or speed, the restriction of speed ratio, can only select the chain of a certain specification, for example certain equipment adopts 32A model or the 32B model of same pitch, the roller chain intensity of 32A model is 222.4kN, the roller chain intensity of 32B model is 250kN, in use, no matter be the roller chain of 32A model or 32B model, its intensity is all inadequate, in use, very fast (as a week) will rupture, life-span is short, but, due to the restriction of mechanical space or oneself, through the product of design typification and batch production, in the use at chain, oneself cannot select the roller chain (intensity is large) of high one grade of standard size again, can only frequently change this chain, affect the use of equipment, and poor reliability, user cost is high.
Model utility content
The technical problem that the utility model solves is to provide a kind of bush roller chain, the problem proposing to solve background technique.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of bush roller chain, comprise the outer link that two rows be arranged in parallel, between two exclusive chain links, be provided with middle shot in parallel, the both sides of middle shot and the inner side of outer link are all provided with inner link, outer link, middle shot and inner link are " 8 " font and pass through together with bearing pin cross-under, between inner link and bearing pin, be provided with sleeve, the outer surface of sleeve is socketed with roller, bearing pin inner link and outer link are interwoven, between every two adjacent bearing pins, be provided with only lock pin, only lock pin is located at the outer surface of outer link; The bearing pin of sleeve-barrel roollr link ends is connected with connecting link, and the outer end cross-under of connecting link has connection bearing pin.
The material of described outer link, middle shot, inner link, bearing pin, sleeve, roller, connecting link, connection bearing pin is that alloy is firm.Described sleeve adopts surperficial carbonitriding part.Described roller adopts low-carbon martensite roller.
Compared with prior art, the beneficial effects of the utility model are: this bush roller chain has the features such as high strength, highi degree of accuracy, high wear resistance, and its tensile strength is high, long service life, can be widely used on standard chain transmission device.
