Abstract
The utility model discloses an environmental-protection roller made of polymer composite materials, which comprises roller shafts, wherein both ends of the roll shafts are provided with end covers which are sealed with a barrel body, and both ends in the barrel body are respectively connected with slide rails made of wear-resistance composite materials; pulleys made of the wear-resistance composite materials are respectively connected to the corresponding roller shafts and are in contact with slide ways of the slide rails. The barrel body of the environmental-protection roller made of polymer composite material can be made of super-polymer polyethylene, and the utility model has the more important point that the environmental-protection roller made of polymer composite material adopts a structure of the slide rails and the supporting pulleys which are made of the wear-resistance composite materials and cancels the structure of the original rolling bearing. The structure thoroughly eliminates various defects caused by the drive of the bearing; the pulleys and the slide ways adopt oil-free lubrication so that the utility model has the advantage of simple and reliable use and maintenance; the pulleys and the slide ways form a point-contact type so that the environmental protection roller made of polymer composite material has small friction force, therefore the utility model has the advantages of energy saving, environmental protection, high durability, corrosion resistance, safety, etc., and can completely replace the existing roller.
Description
Technical field
The utility model belongs to the bracing or strutting arrangement of belt transportation, is specifically related to a kind of carrying roller that does not have antifriction-bearing box.
Background technology
At present, the material of Idler roller generally adopts steel structure both at home and abroad, supports rotating element and adopts antifriction-bearing box.This carrying roller life-span is generally shorter; Roller bearings, long-term use easily cause insufficient lubrication, and noise is very big; Steel structure cost height, perishable, the belt feeder in particularly coastal steel mill, harbour, the stock ground.
Summary of the invention
The purpose of this utility model is to provide a kind of polymer composite environmental protection carrying roller that does not have antifriction-bearing box, to address the above problem.
The technical solution of the utility model is: polymer composite environmental protection carrying roller, it comprises roll shaft, end cover is established at the roll shaft two ends, seal between end cap and the cylindrical shell, two ends connect the slide rail that wearing composite material is made respectively in the cylindrical shell, connect wearing composite material respectively on the corresponding roll shaft and make pulley, pulley contacts with the slideway of slide rail.
The cylindrical shell of this carrying roller can adopt the ultra high molecular polyethylene material, and this material weight is light, wear resisting property good, toughness and processing characteristics are preferably arranged; Wear resisting property is 5-7 a times of steel, and heatproof can reach 300 ℃.At present, this material is widely used in industries such as metallurgy, coal, electric power, cement and uses as high-abrasive material.Slide rail and support pulley structure that this carrying roller of what is more important has adopted wearing composite material to make have been cancelled original rolling bearing structure.This composite material, its hardness is higher, and resistance to abrasion is better, and impact resistance is strong, and this material also is widely used in industries such as metallurgy, coal, electric power, cement to be used as high-abrasive material.This structure has thoroughly been eliminated the various drawbacks of bearing transmission; Adopt oil-free lubrication between pulley and the slideway, working service is simple and reliable; Pulley is that point contacts with slideway, and friction force is little.Therefore this product has many advantages such as energy-saving and environmental protection, durable, withstanding corrosion, safety, complete alternative existing carrying roller.

The specific embodiment
As shown in Figure 1, cylindrical shell 1 adopts the ultra high molecular polyethylene material, and screw thread 7 is established at two ends, its inwall step 8 of limiting.The slide rail 2 that wearing composite material is made is connected with cylindrical shell 1 screw thread 7 by the screw thread 9 on it.Slide rail 2 is spliced by two at least, is two splicings as shown.Cylindrical shell 1 two ends connect sealing inner end cap 3 respectively by screw thread, and sealing inner end cap 3 is pushed down slide rail 2.Roll shaft 4 passes two inner end cap 3.The roll shaft 4 two ends step 10 of limiting, and setscrew nut 11.Establish wearing composite material on the roll shaft between limited step 10 and the setscrew nut 11 and make pulley 5.The shaft section of pulley 5 rim section is trapezoidal 12, and slideway 13 shaft sections of slide rail 2 are trapezoidal or rectangle, among the figure for being rectangle.The two ends of roll shaft 4 also connect sealed outer end lid 6, and outer end cap 6 is connected sealing with roll shaft 4 by screw thread 14.
As shown in Figure 2, between the side of the side of trapezoidal 12 rim section of pulley 5 and trapezoidal slide rail slideway 13 gapped 15.The end face 16 of pulley 5 contacts with the end face 17 of slideway 13, thereby supports whole cylindrical shell 1.
Claims (5)
1, a kind of polymer composite environmental protection carrying roller, it comprises roll shaft, end cover is established at the roll shaft two ends, seal between end cap and the cylindrical shell, it is characterized in that two ends connect the slide rail that wearing composite material is made respectively in the cylindrical shell, connect wearing composite material respectively on the corresponding roll shaft and make pulley, pulley contacts with the slideway of slide rail.
2, polymer composite environmental protection carrying roller according to claim 1 is characterized in that the shaft section of pulley rim part is trapezoidal, and slide rail slideway shaft section is trapezoidal or rectangle.
