The invention relates to an installation structure of a dual-row-chain drum. The installation structure of the dual-row-chain drum comprises an drum body, an drum shaft, a bearing and supports, wherein the bearing is installed between the drum body and the drum shaft; the supports support two ends of the drum shaft; the drum shaft penetrates through the center of the drum body; one end of the drum shaft is of a round body structure, and the other end of the drum shaft is of a D-shaped body structure; a pin hole is formed in the D-shaped body end of the drum shaft; two ends of the drum shaft are respectively inserted into a round hole and a D-shaped hole which are formed in the supports at two sides and are matched with other; a pin shaft is inserted into the pin hole formed in the D-shaped end for positioning; and a dual-row chain wheel is arranged between each of the supports at two ends of the drum shaft and the end surface of the drum body, and the dual-row chain wheel are fixed on the drum shaft through the bearing. The installation structure of the dual-row-chain drum is flexible to use and is high in bearing capability and drive stability.
Description
Technical field
The present invention relates to the logistics equipment technical field, especially a kind of mounting structure of duplex-chain roller.
Background technology
Roller conveyor generally partly is comprised of driving drum, frame, support, drive division etc., be applicable to the conveying of the freight all kinds such as all kinds of casees, bag, pallet, be widely used in the airport, the harbour in the other kinds logistics disposal system such as coal mining industry, can be carried the larger material of single-piece weight and bear larger impact load, it is large to have operational throughput, speed is fast, and it is brisk to turn round, and can realize the characteristics that the shunting of many kinds conllinear is carried.
In the prior art, when needs are carried large material, when perhaps needing to bear greater impact load, the general duplex-chain roller conveyer that adopts is carried, the general normal employing cylindrical shell of the processing of cylinder two ends machine up is with the endoporus of shoulder, one side pressure enters the double gear with bearing, and is integrated with barrel soldering; The other end is pressed into the bearing seat with bearing.Machine up makes the cylindrical shell attenuation on the one hand, has wasted material, has increased cost; The on the other hand difficult assurance of the concentricity of bearings at both ends, beating greatly in cylinder processing rear surface, has affected the in-use performance of cylinder.
Summary of the invention
The applicant is for installing trouble in the above-mentioned existing production technology, the high in cost of production shortcoming provides a kind of mounting structure of duplex-chain roller rational in infrastructure, thereby has improved the load-carrying capacity of cylinder, uses flexibly, reduces cost.
The technical solution adopted in the present invention is as follows:
A kind of mounting structure of duplex-chain roller, comprise roller tube, drum shaft, be installed on bearing between roller tube and the 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 and the D shape hole that has on two side stands inserted respectively at the two ends of described drum shaft, in the pin-and-hole that D body end has, insert the bearing pin location, be respectively arranged with duplex chain wheel between described drum shaft two end supports and the roller tube end face, described duplex chain wheel is fixed on the 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 the roller tube;
Described bearing pin is the R font.
Beneficial effect of the present invention is as follows:
(1) the present invention arranges respectively duplex chain wheel between cylinder and two end supports, thereby can be applied to easily in the 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 invention need to only not need to process a shaft shoulder at an end of drum shaft and become the D physique structure 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, drum shaft D physique structure end be connected with support only need can reach by an end bearing pin positioning instant about the reliable location of end, thereby more guaranteed quality and the service life of product.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the mounting structure of the duplex-chain roller of present embodiment, comprise roller tube 6, drum shaft 7, be installed on bearing 5 between roller tube 6 and the drum shaft 7 and the support at back-up roller axle 7 two ends, drum shaft 7 is through the center of roller tube 6, drum shaft 7 one ends are the round structure, the other end is the D physique structure, and the D body end of drum shaft 7 has pin-and-hole 10; See Fig. 3 and Fig. 4, the circular port that matches 11 and the D shape hole 12 that has on two side stands inserted respectively at the two ends of drum shaft 7, inserts bearing pin 9 location in the pin-and-hole 10 that D body end has, and sees Fig. 5, and bearing pin 9 is the R font; Be respectively arranged with duplex chain wheel 2 between 7 liang of end supports of drum shaft and roller tube 6 end faces, duplex chain wheel 2 is fixed on the drum shaft 7 by bearing 5.
See Fig. 1, sleeve 3 is installed in the sprocket hole of duplex chain wheel 2, and is connected to the inner ring of bearing 5.
