A kind of mounting structure of duplex-chain roller, comprise roller tube, drum shaft, be installed on bearing between roller tube and drum shaft and the support at back-up roller axle two ends, described drum shaft is through the center of roller tube, described drum shaft one end is the round structure, the other end is the D physique structure, and the D body end of described drum shaft has pin-and-hole; The circular port that matches that has on two side stands and D shape hole are inserted respectively in the two ends of described drum shaft, inserting bearing pin in the pin-and-hole that D body end has locates, be respectively arranged with duplex chain wheel between described drum shaft two end supports and roller tube end face, described duplex chain wheel is fixed on drum shaft by bearing.

As further improvement in the technical proposal:

Sleeve is installed in the sprocket hole of duplex chain wheel, and is connected to the inner ring of bearing;

Duplex chain wheel one end periphery is by being fixedly welded on roller tube;

Described bearing pin is the R font.

The beneficial effects of the utility model are as follows:

(1) the utility model arranges respectively duplex chain wheel between cylinder and two end supports, thereby can be applied to easily in duplex chain wheel drive transfer machine system, and use flexibly, can be according to the different operating needs choice for uses duplex chain wheel of an end wherein, or requiring to carry high occasion, the duplex chain wheel at two ends uses simultaneously, and its load-carrying capacity is high, stable drive.

(2) drum shaft of the present utility model need to only not need to become the D physique structure at end processing one shaft shoulder of drum shaft in the two ends of axle machining screw, and the other end is processed into the round structure, has simplified processing technology; Install more easyly, saved the set-up time, improved installation effectiveness.

(3) to adopt an end be the D physique structure to drum shaft, and an end is the round structure, and drum shaft D physique structure end is connected with support only to be needed can to reach the left and right by an end bearing pin positioning instant and hold reliably and locate, thereby more guaranteed quality and the service life of product.
