Description
Technical field
The utility model is related to a kind of transmission systems, particularly a kind of chain system of achievable automatic tension function.
Background technology
The conveyer belt of chain-type is a kind of common transmission system, when driving wheel rotates, can drive be supported on driving wheel and
Chain on follower is moved to some direction to realize the transmission of movement, since chain in use can be unavoidable
There is situation about being stretched, the entire length for causing chain is elongated, and such chain is just present with loose during operation
Phenomenon, if elongated amount is excessive, it is also possible to the phenomenon that chain is caused to can not operate normally.To solve the above-mentioned problems, in chain
Can all configure swelling device in system, and traditional swelling device for Manual push-pull block form, it is necessary to periodically carry out artificial
It adjusts, to ensure the tensioner degree of chain, thus needs operating personnel's routine observation and operation, add the cost and labor of maintenance
Momentum.Therefore need one kind being capable of solution to the problems described above or device now.
The content of the invention
The utility model is to solve the above-mentioned deficiency present in the prior art, proposes that one kind is simple in structure, design is skilful
It is wonderful, it, can be in real time according to the chain system of the degree of chain elongation automatic adjustment tensioner degree without manual operation.
The technical solution of the utility model is：A kind of chain system of achievable automatic tension function, feature exist
In：The system comprises motors 1 and fixed pulley 2, and chain 4 is supported by jointly between the output shaft 3 of motor 1 and fixed pulley 2, with
4 phase of chain is furnished with tension mechanism, and the tension mechanism includes tensioner frame 5, genesis analysis is offered in tensioner frame 5
Slideway 6, slidably connect sliding block 7 in slideway 6, have expansion tightening wheel 8 by support shaft rotational support on the sliding block 7, in cunning
Be additionally provided with tensioner spring 9 in the slideway 6 of the top of block 7, and the both ends of the tensioner spring 9 respectively in the top of tensioner frame 5
Wall is contacted with the upper surface of sliding block 7.
Simultaneously wound on the output shaft 3 to have multiple chains 4, each chain 4 is mutually furnished with tension mechanism.
The utility model compared with the existing technology, has the following advantages that：
The chain system of this kind of structure type, for traditional tension mechanism periodically manually adjusted institute in use
Existing variety of problems designs a kind of mechanism that can be compensated chain elongation amount automatically, chain is allowed to keep tensioner state always,
It carries out real-time compensation, even if so chain will not be sent out because of the elongation of certain reason using mechanisms such as spring, sliding blocks to chain
The phenomenon that raw relaxation, and then ensure that the stability and reliability of chain drive, and the structure of this chain system is simple, if
Count it is ingenious, it is rationally distributed, it can be said that it possesses a variety of advantages, particularly suitable for promoting and applying in the art, city
Field prospect is very wide.
Description of the drawings
Fig. 1 is the structure diagram of the utility model embodiment.
Fig. 2 is the structure diagram of tension mechanism in the utility model embodiment.
Specific embodiment
Below in conjunction with description of the drawings specific embodiment of the present utility model.As shown in Figure 1 and Figure 2：One kind can be achieved certainly
The chain system of dynamic tensioner function, including motor 1 and fixed pulley 2, supports jointly between the output shaft 3 of motor 1 and fixed pulley 2
There is chain 4, with 4 phase of chain equipped with tension mechanism, tension mechanism includes a tensioner frame 5, slideway is offered inside tensioner frame 5
6, and 6 genesis analysis of slideway, sliding block 7 is slidably connected in slideway 6, support shaft is provided on sliding block 7, is rotated in support shaft
Expansion tightening wheel 8 is supported by, tensioner spring 9, and the top of tensioner spring 9 and tensioner are additionally provided in the slideway 6 above sliding block 7
The inner wall contact at 5 top of frame, and upper surface of the bottom of tensioner spring 9 then with sliding block 7 is in contact；It can on above-mentioned output shaft 3
To set more chains 4, with every chain 4 all mutually equipped with a set of tension mechanism, automatic tension is carried out to chain 4；
The course of work of the chain system of the achievable automatic tension function of the utility model embodiment is as follows：The present apparatus is pacified
After the completion of dress, motor 1 works, and output shaft 3 is driven to rotate, and then drive chain 4 moves, since expansion tightening wheel 8 is contacted with chain 4,
And tensioner spring 9 is always sliding block 7 and the one direction down thrust of offer of expansion tightening wheel 8, expansion tightening wheel 8 allows chain 4 to keep tensioner
State；
It working after a period of time, chain 4 extends for various reasons to be caused to relax, while chain 4 extends, chain
4 strength for giving sliding block 7 become smaller, and sliding block 7 is pushed down on a distance by tensioner spring 9, and chain 4 is allowed to remain tensioner shape
State, the system can ensure that chain 4 is in tensioner state at any time.
Claims (2)
