Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

Fig. 2 is a front view of the three-pin special chain of the present invention.

As shown in fig. 1 and 2, the utility model provides a three-pin special chain, which comprises a chain plate 1, a bearing roller 2, a first pin 3, a sleeve 4 and a second pin 5;

the bearing rollers 2 are longitudinally arranged, and the chain plates 1 are positioned at two ends of the bearing rollers 2; a plurality of groups of first pin shafts 3 are transversely arranged, sleeves 4 are arranged corresponding to the first pin shafts 3, and the two chain plates 1 are connected through the first pin shafts 3 and the sleeves 4; the second pin shafts 5 are positioned between two adjacent first pin shafts 3, and the second pin shafts 5 are connected with the bearing idler wheels 2 and the chain plates 1;

The diameter of the first pin shaft 3 is smaller than that of the second pin shaft 5, and the diameter of the bearing roller 2 is larger than the height of the chain plate 1.

In an alternative embodiment, the first pin 3 is interference-fitted with the link plate 1.

In an alternative embodiment, the sleeve 4 is an interference fit with the link plate 1.

In an alternative embodiment, the first pin 3 is a clearance fit with the sleeve 4.

In an alternative embodiment, the second pin 5 is in interference fit with the link plate 1.

in an alternative embodiment, the second pin 5 is a clearance fit with the carrier roller 2.

The utility model discloses in, through increasing second round pin axle 5 and bearing roller 2, and with first round pin axle 3 suitable attenuate, cancel the gyro wheel that original chain both ends need be joined in marriage the area, the cost of manufacture of chain reduces, the cost greatly reduced of corresponding equipment also, bearing roller 2 is greater than the diameter of link joint 1, it is bigger than the gyro wheel on the original chain to bear gyro wheel 2 promptly, it is more steady to operate on the track, make the stability of equipment use and its life-span greatly increased, it is also more convenient to operate maintenance and later stage spare part change to it.
