Abstract
The utility model relates to a carrying idler for a conveying machine, which comprises a roller 6, a positioning sealing sleeve 4 which is arranged on the upper and the lower ends of the roller 6, a shaft shoulder retainer ring 2 and a shaft 1. The positioning sealing sleeve 4 is an integrative body, the outer circle forms interference fit with the inner wall of the roller 6, and an inner hole forms clearance fit with the shaft 1 and plays the function of a sliding bearing; in addition, the upper and the lower ends of the positioning sealing sleeve 4 are respectively provided with a retainer ring 3, and the outer circle is tightly matched and fixed with the inner wall of the positioning sealing sleeve 4; as main components of the idler are made of engineering plastic, the abrasion for a conveying belt can be effectively reduced. The utility model has the advantages of simple structure, convenient assemblage and easy replacement, and the service life of the idler and the use value can be improved.
Description
The utility model relates to the carrying idler in the conveying machinery.
Carrying idler generally transmits object with dried conveyer, to play the supporting carrying conveying effect of article.In the carrying roller table 27 among " mechanical design handbook " P27-117 that China Machine Press 90 years publishes～125 pages, list the flute profile carrying roller, the transition carrying roller, impact idler, aligning carrier roller, the carrying roller of types such as parallel roll, they all belong to the integral type carrying roller, adopt the steel ring roller to add the type of drive of antifriction-bearing box, take on the structure tourelle is welded on the cylinder, and the location sealing shroud is by tourelle, bearing gland, three parts of seal cover cap are formed, complex structure, tourelle is that consumable accessory is changed inconvenience, can only scrap by whole carrying roller, and the steel carrying roller is to the load-transfer device serious wear, cause load-transfer device shortening in service life, so need often to change, strengthened workman's maintenance capacity and increased cost.Chinese patent 91204203 " carrier roller " adopts the carrier roller tube to replace the steel roller supporting tube, can reduce the wearing and tearing to load-transfer device, but, be subjected to loading capability little, so can not be used for the big occasion of bearing capacity because ceramic plasticity is poor, and its location sealing shroud still takes a plurality of parts to form complex structure.
The purpose of this utility model provides a kind of simple in structure, and is easy to assembly, the carrying roller that is easy to change.
Its objective is and realize like this: carrying roller comprises cylinder and is located at cylinder location sealing shroud, retaining ring for shaft shoulder, the axle at two ends up and down, it is characterized in that locating sealing shroud is one whole, its cylindrical and inner wall of rotary drum interference fit, endoporus cooperates with axle slack, play the plain bearing effect, and the upper/lower terminal at the location sealing shroud is respectively established a back-up ring, and its cylindrical is fixed with location sealing shroud inwall close-fitting.
Be provided with stop screw between location sealing shroud and inner wall of rotary drum, cylinder, location sealing shroud all adopt engineering plastics.
The utility model compared with prior art has the following advantages:
1. the location sealing shroud is one whole on the structure, with the inner wall of rotary drum interference fit, need not weld, and it is reusable that then consumable accessory is changed the back carrying roller, has improved the service life and the value of carrying roller.
2. take to locate sealing shroud and play the plain bearing effect, replace the antifriction-bearing box in the steel carrying roller, only need to be coated with a grease when carrying roller assembles and just can play long-term lubricating effect, need not frequent apply lubrication oil, its self sealss are effective, but actv. is dustproof.
3. the material of carrying roller adopts engineering plastics to replace steel, and it is little to have a coefficient of friction, and toughness is strong, can significantly reduce the wearing and tearing to load-transfer device, and has buffer action, can reduce the impulsive force of axle, guarantees the working strength of axle.Test results proves, belt and the utility model carrying roller moving surface mutually almost do not have wearing and tearing, impel belt to increase the service life, the good heat resistance of engineering plastics, the location sealing shroud is 0.55m/s in speed, roller driving belt speed can be in normal operation under the 3m/s, the axle surface is not had burn, do not have wearing and tearing.
Further describe the utility model below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
As seen from Figure 1, the utility model comprises cylinder 6, stop screw 5, location sealing shroud 4, back-up ring 3, retaining ring for shaft shoulder 2, axle 1, cylinder 6 is the shell of carrying roller, location sealing shroud 4 is one whole the two ends up and down that are arranged on cylinder 6, the inwall interference fit of its cylindrical and cylinder 6, endoporus and axle 1 free-running fit play the plain bearing effect.Sealing shroud is respectively established a back-up ring 3 in two ends about in the of 4 in the location, and its cylindrical is fixed with location sealing shroud 4 close-fittings, plays the axial location effect, and the assurance endoporus is not stung axle.Add retaining ring for shaft shoulder 2 between back-up ring 3 and axle 1, also can play the axial location effect when assembling, axle 1 is arranged at the innermost layer of carrying roller.Stop screw 5 is arranged between location sealing shroud 4 and the cylinder 6, and being used for fixing the location sealing shroud must not rotate.
Claims (3)
1. carrying roller, it comprises cylinder (6) and is located at cylinder (6) location sealing shroud (4), retaining ring for shaft shoulder (2), the axle (1) at two ends up and down, it is as a whole to it is characterized in that locating sealing shroud (4), its cylindrical and cylinder (6) inwall interference fit, endoporus and axle (1) free-running fit, play the plain bearing effect, and respectively establish a back-up ring (3) at the upper/lower terminal of location sealing shroud (4), its cylindrical is fixed with location sealing shroud (4) inwall close-fitting.
