Abstract
The utility model discloses a high-density polythylene idler of belt transporter, comprising an idler cartridge, an idler shaft, a bearing block, a bearing, a gasket, a retaining ring and a circlip. The idler cartridge is connected with the idler shaft through the bearing on the bearing blocks on two ends. The idler cartridge adopts a high-density polythylene idler cartridge. Between two sides, at least one intermediate supporting seat is arranged between the idler cartridge and the idler shaft. The intermediate supporting seat is connected with the idler shaft through the bearing. The outside diameter of the intermediate supporting seat is equal to the inside diameter of the idler cartridge. A transition fit is adopted between the outside diameter of the intermediate supporting seat and the inside diameter of the idler cartridge. One side of the bearing of the intermediate supporting seat is positioned by the steps on the idler shaft, and the inner ring of the bearing is obstructed by the circlip at the other side.
Description
Technical field
The utility model relates to a kind of band conveyor high density polyethylene (HDPE) carrying roller, is used for the belt conveyor tool, holds load-transfer device and load-transfer device is rolled thereon, thereby realize carrying the purpose of goods and materials.
Background technology
It is made that the roller of now used idler for belt conveyer is metal, because the working environment of conveying machinery is relatively poor, often makes the metal roller use the short period interior with regard to corrosion, worn out, influences work.The metal roller surface easily is detained transported substance, often needs its surface of labor cleaning.
Summary of the invention
The purpose of this utility model is to adopt the high density polyethylene (HDPE) roller supporting tube to replace the metal roller, designs a kind of long service life, good, the NA band conveyor high density polyethylene (HDPE) of resistance to abrasion carrying roller.
The technical solution of the utility model:
Band conveyor high density polyethylene (HDPE) carrying roller of the present utility model comprises roller supporting tube, roller carrier shaft, bearing seat, bearing, packing seal, back-up ring, jump ring, roller supporting tube connects by bearing on the bearing seat at two ends and roller carrier shaft axle, roller supporting tube adopts the high density polyethylene (HDPE) roller, between the at both ends, a center support seat is set between roller supporting tube and the roller carrier shaft at least, be connected by bearing between center support seat and the roller carrier shaft, the external diameter of center support seat equates with the internal diameter of roller supporting tube.
Described band conveyor high density polyethylene (HDPE) carrying roller is a transition fit between the external diameter of center support seat and the roller supporting tube internal diameter.
Described band conveyor high density polyethylene (HDPE) carrying roller, bearing one side of center support seat is by the location of the step on the roller carrier shaft, and opposite side is then blocked bearing inner ring by jump ring.
The utility model has the advantages that: it is compared with traditional steel carrying roller, prolongs three times service life, and resistance to abrasion is seven times of steel, 27 times of copper, 4 times of nylon; Can under unlubricated condition, work, the good foreign matter property held is arranged; It is little to have coefficient of friction, low temperature resistant, low noise, advantage such as nontoxic; The chemical inertness height, acidproof, alkaline-resisting, characteristics such as the salt tolerant burn into is not aging, light specific gravity, impact strength height.This carrying roller has installed a supporting base additional at the cylinder middle part, has solved the recessed phenomenon of carrying roller preferably, makes carrying roller lengthening in service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1: this carrying roller is made up of roller carrier shaft, bearing seat, center support seat, bearing, packing seal, back-up ring, jump ring and high density polyethylene (HDPE) roller etc.
Same as the prior art is that this carrying roller roller supporting tube 7 passes through the bearing 6 and 1 company of roller carrier shaft on the bearing seat 5 at two ends, and the bearing outside is made up of packing seal 4, jump ring 2, back-up ring 3 etc. successively.
The utility model adopts the high density polyethylene (HDPE) roller, is provided with the center support seat, prevents when carrying roller is longer, and is recessed in the middle of the carrying roller, early damages to cause carrying roller.
Concrete structure is: middle bearing 9 is pressed in the center support seat 8, again with its integral installation on roller carrier shaft 1.Between the internal diameter of middle bearing 9 and the roller carrier shaft 1 is interference fit, and a side of middle bearing 9 is by the step on the axle 10 location, and opposite side is blocked bearing inner ring by jump ring 11.
Roller carrier shaft and center support seat integral body are packed in the high density polyethylene (HDPE) roller 7, the internal diameter of the external diameter of center support seat 8 and roller 7 is a transition fit again.The center support seat is fixed outside cylinder with screw.
The number of center support seat can be according to the length and the particular case setting of carrying roller, and general roller 800-1200mm adds a center support seat, adds two center support seats more than the 1200-1600mm, can add three more than the 1600mm.
Claims (3)
1. band conveyor high density polyethylene (HDPE) carrying roller, comprise roller supporting tube, roller carrier shaft, bearing seat, bearing, packing seal, back-up ring, jump ring, roller supporting tube connects by bearing on the bearing seat at two ends and roller carrier shaft axle, the bearing outside has packing seal, jump ring, back-up ring successively, it is characterized in that: roller supporting tube adopts the high density polyethylene (HDPE) roller, between the at both ends, a center support seat is set between roller supporting tube and the roller carrier shaft at least, be connected by bearing between center support seat and the roller carrier shaft, the external diameter of center support seat equates with the internal diameter of roller supporting tube.
2. band conveyor high density polyethylene (HDPE) carrying roller according to claim 1 is characterized in that: be transition fit between the external diameter of center support seat and the roller supporting tube internal diameter.
