Abstract
The utility model relates to a combined-type transmission chain which comprises a pin shaft and multiple chain links sequentially arranged along the running direction of the transmission chain. Each chain link is formed by splicing a long chain plate and a short chain plate along the width direction of the corresponding chain link, the pin shaft penetrates pin shaft holes of the long chain plates and the short chain plates to hinge a front chain link and a rear chain link together, the length of each long chain plate is twice that of each short chain plate, and the long chain plates and the short chain plates of adjacent chain links are arranged in a mutually staggered manner. A transmission chain formed only by sequentially connecting short chain plates is small in transmission power, the transmission power of a transmission chain formed only by sequentially connecting long chain plates is twice that of the transmission chain formed only by sequentially connecting the short chain plates, but the combined-type transmission chain is formed by mutually combining the long chain plates and the short chain plates, so that the transmission power of the combined-type transmission chain is triple that of the transmission chain formed by the short chain plates and one and half times that of the transmission chain formed by the long short chain plates; the transmission chains in three specifications can be formed by combining only by stocking up chain link units in two specifications, so that stock quantity is reduced, and die cost of the chain link units is lowered.
Description
Technical field
The utility model relates to a kind of transmission device, particularly a kind of combined driving chain.
Background technique
The advantages such as linked transmission has the transmission distance, and transmission efficiency is high and operate steadily, widely apply in industry manufacture field, according to different demands, linked transmission is divided into again polytype, and according to the requirement of different delivering powers, the size of every kind of Transmitted chains is different again again.Transmitted chains comprises a plurality of carrier bars that connect successively by chain pin, and its chain link fabric width of Transmitted chains that delivering power is large is wider, and its chain link fabric width of Transmitted chains that delivering power is little is narrow.According to the demand of different transmission powers, need to process the link units of multiple fabric width, in the situation that Market competition, multiple link units all will be produced certain stock, with the demand of rapid satisfying the market, has caused manufacture cost high, most of the products are overstocked.
The model utility content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of combined driving chain is provided, and link units that can be less by transmission power splices the Transmitted chains that transmission power is larger, has reduced the stock kind.
For solving above technical problem, a kind of combined driving chain of the present utility model, a plurality of chain links that comprise bearing pin and be arranged in order along the Transmitted chains traffic direction, the described chain link of every joint is spliced along chain link fabric width direction by long-chain plate and short chain plate respectively, described bearing pin is hinged by front and back two chain links through the pin shaft hole of long-chain plate and short chain plate, the length of each described long-chain plate is the twice of each described short chain plate length, and long-chain plate and the short chain plate of adjacent link are mutually staggered.
With respect to prior art, the utility model has been obtained following beneficial effect: its transmission power of Transmitted chains that adopts separately the short chain plate to be connected in sequence is less, its transmission power of Transmitted chains that adopts the long-chain plate to be connected in sequence separately doubles than short chain plate, the utility model adopts long-chain plate and short chain plate mutually to be combined into the wider Transmitted chains of fabric width, its transmission power is three times of short chain plate, is the half as much again of long-chain plate; So need only the link units of two kinds of specifications of stock, just can be combined into the Transmitted chains of three kinds of specifications, reduced the stock amount, also reduced the die cost of link units; The long-chain plate of adjacent link and short chain plate are mutually staggered can make the connection of Transmitted chains more reliable, moves more steady.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, accompanying drawing only provides reference and explanation use, non-in order to limit the utility model.
The structural representation that Fig. 1 is the utility model combined driving chain.
In figure: 1. bearing pin; 2. long-chain plate; 3. short chain plate.
Embodiment
As shown in Figure 1, combined driving chain of the present utility model, a plurality of chain links that comprise bearing pin 1 and be arranged in order along the Transmitted chains traffic direction, every pitch chain joint is spliced along chain link fabric width direction by long-chain plate 2 and short chain plate 3 respectively, bearing pin 1 is hinged by front and back two chain links through the pin shaft hole of long-chain plate 2 and short chain plate 3, the length of each long-chain plate 2 is the twice of each short chain plate 3 length, and long-chain plate 2 and the short chain plate 3 of adjacent link are mutually staggered.
Its transmission power of Transmitted chains that adopts short chain plate 3 to be connected in sequence separately is less, its transmission power of Transmitted chains that adopts long-chain plate 2 to be connected in sequence separately doubles than short chain plate 3, the utility model adopts long-chain plate 2 and short chain plate 3 mutually to be combined into the wider Transmitted chains of fabric width, its transmission power is three times of short chain plate 3, is the half as much again of long-chain plate 2; So need only the link units of two kinds of specifications of stock, just can be combined into the Transmitted chains of three kinds of specifications, reduced the stock amount, also reduced the die cost of link units.
The foregoing is only the better possible embodiments of the utility model, non-so limit to scope of patent protection of the present utility model.In addition to the implementation, the utility model can also have other mode of executions, for example can also arrange more long-chain plate and short chain plate further to enlarge transmission power at each chain link.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.The utility model can pass through or adopt existing techniques in realizing without the technical characteristics of describing, and does not repeat them here.
Claims (1)
1. a combined driving chain, a plurality of chain links that comprise bearing pin and be arranged in order along the Transmitted chains traffic direction, it is characterized in that: the described chain link of every joint is spliced along chain link fabric width direction by long-chain plate and short chain plate respectively, described bearing pin is hinged by front and back two chain links through the pin shaft hole of long-chain plate and short chain plate, the length of each described long-chain plate is the twice of each described short chain plate length, and long-chain plate and the short chain plate of adjacent link are mutually staggered.
