Background
The chain basically belongs to labor-intensive products, and many developed countries have turned to the development of Chinese production, which brings new opportunities for the chain to expand export in China. Chain manufacturing capability is a determining factor in the chain manufacturing industry, and the center of chain manufacturing strength is the process level of chain manufacturing. The extent of the chain manufacturing process depends to a large extent on the extent of chain consumption expertise. The degree of the strength of the process device directly influences the consumption efficiency of chain manufacturing companies and the economic benefit of the quality degree of products.
Chain transmission is a transmission mode for transmitting the motion and power of a driving sprocket with a special tooth form to a driven sprocket with a special tooth form through a chain. The chain transmission has many advantages, compared with the belt transmission, the chain transmission has no elastic sliding and slipping phenomena, the average transmission ratio is accurate, the work is reliable, and the efficiency is high; the transmission power is large, the overload capacity is strong, and the transmission size under the same working condition is small; the required tension is small, and the pressure acting on the shaft is small; the chain transmission can work in severe environments such as high temperature, humidity, dustiness, pollution and the like, so that chain transmission is an essential important part of a transmission part on some modern mechanical equipment and some special equipment.
In recent years, the chain industry in China pays great attention to the investment of hardware equipment, chain enterprises invest a large amount of funds, manpower and material resources, a technical improvement project of electromechanical integration of chain using equipment is implemented, a batch of chain manufacturing exclusive using equipment with higher strength is successfully developed and put into use, the professional consumption efficiency is improved, the process progress is more reasonable, the functions are more complete, and the manufacturing strength of medium and small-specification chains in China is greatly improved.
The common chain in the market usually comprises outer chain piece, interior chain piece, chain roll and round pin axle, and if this chain was applied to small-size actuating mechanism, mechanical strength such as its tensile strength and fatigue strength were far greater than actuating mechanism needs, but, when the intensity that the application needs was far less than the intensity that the chain can bear, relatively speaking, the cost of the chain of this design just has improved, therefore, need how to maintain the condition of the holistic structural strength of chain, further simplify the structure of chain again, become the problem that chain manufacturer needed to overcome now urgently.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to solve the defects of the prior art, the utility model provides an ultralight chain, which overcomes the defects of more material consumption and heavy weight and is suitable for a transmission system needing small load bearing.
The technical scheme is as follows: in order to achieve the above object, the present invention provides an ultra light chain, which is a ring body formed by connecting a plurality of chain links in series, wherein the front end of one of the adjacent chain links is connected in a freely rotatable manner with respect to the rear end of the other chain link, and the chain links include: the chain piece, the lug fixed together with the chain piece, the pin shaft fixing the chain piece and the lug together, the lug is provided with a lug hole, and the chain piece is provided with a chain piece hole;
as a further preferred aspect of the present invention, the pin shaft sequentially passes through the chain piece hole on the chain piece and the projection hole on the projection to fix the two chain pieces together.
As a further preferred aspect of the present invention, the chain piece hole and the projection hole have the same size.
As a further preferred aspect of the present invention, when the pin shaft passes through the chain piece, the positions of the chain piece hole and the protrusion hole are offset.
As a further preferred aspect of the present invention, the chain piece and the protruding block are fixed together by integral molding, thereby increasing the reliability of the chain link in use and the strength of the inner link plate bearing load.
As a further preferred aspect of the present invention, the pin shaft is movably riveted to the link plate and the projection by the assembling machine.
As a further preferred feature of the present invention, the chain piece and the projection are rotatable relative to each other.
Has the advantages that: an ultralight chain, compare with prior art, have following advantage:
1. the chain roller and the outer chain sheet are not needed, the structure is simple, the installation is convenient, the time required by assembly is shortened, and the working efficiency is improved;
2. the chain pieces are connected together end to end through the pin shafts, so that the working reliability and stability of the chain links are ensured;
3. the lug and the chain sheet are processed in an integrated forming mode, the reliability and the stability of the work of the chain link are guaranteed, the condition that a roller is broken or falls off or the condition that a chain is poor due to the abrasion of one part in the prior art is reduced, the quality yield of the whole chain is improved, and the carbon discharge generated in the whole manufacturing process is reduced.
