Abstract
The invention relates to a roller structure for conveyors. The structure comprises a roller body, a roller shaft and bearings, wherein the roller shaft passes through the center of the roller, the outside surfaces of the two ends of the roller shaft are respectively provided with a convex point, the bearings are respectively arranged between the two ends of the roller shaft and a roller, the two end faces of the outside of the roller body are respectively provided with a R-shaped arc curled edge, the outer edge of one end of an outer ring of the bearing is provided with a shoulder, and the shoulder is propped against the R-shaped arc curled edge. The roller structure provided by the invention is easy to manufacture, safe, reliable, and low in cost.
Description
Technical field
The present invention relates to the logistics equipment field, especially be applied to the cylinder on the conveying arrangement.
Background technology
Roller conveyor 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 other logistics disposal systems such as coal mining industry, generally partly form, and can carry the bigger material of single-piece weight and bear bigger impact load by frame, cylinder, rolling stand, drive division etc.; 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.Its intermediate roll is for driving the circle tube assembly of load-transfer device.The version of cylinder can be divided into power drum and unpowered cylinder by type of drive, and unpowered roller frame has simple in structure, and reliability is high, simple installation, advantages such as working service convenience.
And cylinder of the prior art generally adopts a roller tube and an axle separation type cylinder to install when installing, the work capacity when having increased last mounting cylinder; When the external fixation spare of axle damaged, axle was easy to generate separation phenomenon with cylinder in addition, operated dangerously, and reliability is low.
Summary of the invention
The applicant separates to above-mentioned existing production axis and easy generation of cylinder, has shortcomings such as potential safety hazard, and a kind of delicate structure is provided, and easily manufactured conveyer is used roller frame, thereby has improved the safe reliability of cylinder, cost-cutting.
The technical scheme that the present invention adopted is following:
A kind of conveyer is used roller frame; Comprise roller tube, drum shaft and bearing, said drum shaft is provided with salient point through the center of cylinder respectively on the two ends outside face of said drum shaft; Bearing is installed respectively between drum shaft two ends and cylinder; The outer both ends of the surface of said roller tube are provided with R shape circular arc crimping, and outside race one end outer rim place is provided with shoulder, said shoulder and R shape circular arc crimping butt.Its further technical scheme is:
The two ends of said drum shaft are the flat structure of axle;
Said bearing is the punching type bearing.
Beneficial effect of the present invention is following:
(1) the drum shaft two ends are provided with salient point, and the axle that has salient point cooperates closely with the cylinder bearings at both ends, makes the bearing axial location reliable, have avoided can producing in the prior art axle and have produced the phenomenon of separating with cylinder;
(2) the present invention adopts the cylinder two ends to adopt R shape circular arc bead structure, and is easy to process, and the smooth rounding of back roll end face is installed;
(3) roller tube R shape circular arc end face produces butt with the bearing shoulder, has further fixed bearing;
(4) two ends of drum shaft are the flat structure of axle, are convenient to the fixing of axle, can prevent that axle from producing rotation, in addition when axle and two body side frames are located by connecting, are convenient to and being connected of framework, and the while can further make an axial location reliable;
(5) the punching type bearing is used at the cylinder two ends, makes bearing have the better seal performance.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an A-A cutaway view among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, conveyer of the present invention is used roller frame, comprises roller tube 5, drum shaft 4 and bearing 2; Drum shaft 4 is through the center of cylinder; On the two ends outside face of drum shaft 4 salient point 3 is set respectively, between drum shaft 4 two ends and cylinder, bearing 2 is installed respectively, roller tube 5 outer faces are provided with R shape circular arc crimping 1; One end outer rim place, bearing 2 outer rings is provided with shoulder 7, shoulder 7 and R shape circular arc crimping 1 butt; The two ends of drum shaft 4 are flat structure 6 (see figure 2)s of axle; Cylinder bearings at both ends 2 is the punching type bearing.
During actual processing and manufacturing; Outer surface squeezes out two salient points 3 respectively at the two ends of drum shaft 4 to adopt compression machine earlier, and roller tube 5 is carried out crimping processing, makes roller tube 5 two ends form R shape circular arc crimping 1; During installation; Drum shaft 4 is run through in the roller tube 5, and make drum shaft 4 expose to cylindrical shell 5, the two ends from drum shaft 4 penetrate bearing 2 respectively then; Employing is pressed into equipment bearing 2 is pressed into roller tube 5; Outer ring and the cylindrical shell R shape circular arc 1 of the bearing 2 of processing shoulder produced be connected, and make an end of bearing 2 be limited in salient point 3 simultaneously, make bearing and cylindrical shell installing and locating reliable through axially reach radial fit and cylinder end face bead structure between bearing 2 and the axle 4.
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
Claims (3)
1. a conveyer is used roller frame; Comprise roller tube, drum shaft and bearing, said drum shaft is characterized in that through the center of cylinder: on the two ends outside face of said drum shaft salient point is set respectively; Bearing is installed respectively between drum shaft two ends and cylinder; The outer both ends of the surface of said roller tube are provided with R shape circular arc crimping, and outside race one end outer rim place is provided with shoulder, said shoulder and R shape circular arc crimping butt.
2. conveyer as claimed in claim 1 is used roller frame, it is characterized in that: the two ends of said drum shaft are the flat structure of axle.
