Abstract

The utility model relates to a duplex-chain roller which comprises a roller, a roller spindle, a bearing mounted between the roller and the roller spindle, and brackets for supporting two ends of the roller spindle, wherein the roller spindle penetrates the center of the roller; one end of the roller spindle takes the structure of a rounded body; the other end of the roller spindle is of a D-shaped body structure; a pin hole is formed at one D-shaped body end of the roller spindle; two ends of the roller spindle are respectively inserted into a circular hole and a D-shaped hole formed on the brackets on two sides in a matched manner; a hinge pin is inserted into the pin hole formed at the D-shaped end to position; a chain wheel is arranged between the bracket on one side of the roller spindle and the end surface of the roller; and the chain wheel is a duplex wheel chain, and is fixed to one end of the roller spindle through the bearing.

Description

The duplex chain cylinder

Technical field

The utility model relates to the logistics equipment field, especially is applicable to the duplex chain cylinder in the duplex chain wheel drive transfer machine system.

Background technology

Roller conveyor generally partly is made up of driving drum, frame, support, drive division etc., is applicable to the conveying of freight all kinds such as all kinds of casees, bag, pallet, is widely used in the airport; The harbour in the other kinds logistics disposal system such as coal mining industry, can be carried the bigger material of single-piece weight and bear bigger impact load; It is big 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 big material; In the time of perhaps need bearing greater impact load, generally adopt the duplex chain roller conveyor to carry, the general normal employing cylindrical shell of the processing of cylinder two ends machine up has the endoporus of shoulder; One end is pressed into the double gear that has bearing, and is welded as a whole with cylindrical shell; The other end is pressed into the bearing seat that has bearing.Machine up makes the cylindrical shell attenuation on the one hand, has wasted material, has increased cost; The concentricity of bearings at both ends cannot say for sure to demonstrate,prove on the other hand, and beating greatly in surface, cylinder processing back, has influenced the in-use performance of cylinder.

The utility model content

The applicant provides a kind of delicate structure to shortcoming in the above-mentioned prior art, easily manufactured duplex chain cylinder, thus improved the load-carrying capacity of cylinder, reduced cost.

The technical scheme that the utility model adopted is following:

A kind of duplex chain cylinder; Comprise cylinder, drum shaft, be installed on bearing and the support at back-up roller axle two ends between cylinder and the drum shaft; Said drum shaft is through the center of cylinder; Said drum shaft one end is the round structure, and the other end is the D physique structure, and the D body end of said drum shaft has pin-and-hole; Circular port that matches and the D shape hole that has on two side stands inserted at the two ends of said drum shaft respectively; In the pin-and-hole that D body end has, insert the bearing pin location; It is characterized in that: be provided with sprocket wheel between said drum shaft one side stand and the cylinder end face; Said sprocket wheel is the double rows of teeth endless chain, and said sprocket wheel passes through bearing fixing in an end of drum shaft.Its further technical scheme is:

Sleeve is installed in the sprocket hole of sprocket wheel, and is connected to bearing cone;

Sprocket wheel one end periphery is through being fixedly welded on the roller tube;

Said bearing pin is the R font.

The beneficial effect of the utility model is following:

(1) the utility model is provided with a double rows of teeth endless chain between a cylinder and a body side frame, thereby can be applied to easily in the duplex chain wheel drive transfer machine system, and load-carrying capacity is high, stable drive.

(2) drum shaft of the utility model need be at the two ends of axle machining screw, only need to process a shaft shoulder and become the D physique structure at an end of drum shaft, 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 through an end bearing pin positioning instant about the reliable location of end, thereby more guaranteed the quality and the service life of product.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.

Like Fig. 1, shown in Figure 2; The described device of the utility model comprises a kind of duplex chain cylinder; Comprise cylinder 6, drum shaft 7, be installed on bearing and the support 1 at back-up roller axle 7 two ends between cylinder 6 and the drum shaft 7, drum shaft 7 is through the center of cylinder 6, and 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 11; The circular port that matches 12 and D shape hole 13 (the seeing Fig. 3, Fig. 4) that has on two side stands 1,11 inserted at the two ends of drum shaft 7 respectively; In the pin-and-hole 11 that D body end has, insert R font bearing pin 10 location (see figure 5)s; Be provided with sprocket wheel 2 between drum shaft 7 one side stands 1 and cylinder 6 end faces; Sprocket wheel 2 is the double rows of teeth endless chain, and sprocket wheel 2 is fixed in an end of drum shaft 7 through bearing 5; Sleeve 3 is installed in the sprocket hole of sprocket wheel 2, and is connected to the inner ring of bearing 5; Sprocket wheel 2 one end peripheries are fixed on the roller tube through welding 4.

During actual installation and processing, earlier bearing 5 is pressed in the double rows of teeth endless chain 2, accomplish after the crimping processing the center of drum shaft 7 through cylinder 6 at the roller tube two ends, and be pressed into bearing 14 at the D of drum shaft 7 body end, and with axle sleeve 8 axial location; The double rows of teeth endless chain 2 that drum shaft 7 another round noses are packed into and had bearing 5, and through welding 4 sprocket wheel 2 one end peripheries are fixed on the roller tube; Then sleeve 3 is installed in the sprocket hole of sprocket wheel 2, and is connected to the inner ring of bearing 5; Again the round structure end of drum shaft 7 being inserted 1 of a side stand opens in the circular hole 12; Cylinder 6 and drum shaft 7 are the level of state; Insert bearing pin 10 in the pin-and-hole 11 after the insertion in the D shape hole 13 of again the aligning opposite side support 9 of the axle other end being opened, and has promptly accomplished whole assemblings of the utility model.

The utility model is provided with a double rows of teeth endless chain between a cylinder and a body side frame, thereby can be applied to easily in the duplex chain wheel drive transfer machine system, and load-carrying capacity is high, stable drive.

More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the spirit of the utility model, the utility model can be done any type of modification.
