Abstract
The utility model relates to a steel wire rope abrasion-resistant carrier roller for a gantry crane. The carrier roller comprises a hub and bearings; two sides of the hub are correspondingly provided with the bearings; a groove surrounding the hub is internally provided with a coating; outer sides of the bearings are provided with glands; rolling-bar-type bearings are adopted as the bearings; a steel wire rope abrasion-resistant carrier roller wheel which is provided with a polyurethane coating and is used for the gantry crane lowers the steel wire rope abrasion intensity, and prevents the service life of the steel wire rope from being shortened because the steel wire rope is abraded and fractured by external force for long time; the service life of the carrier roller is prolonged effectively, and the maintaining expense is saved greatly; the structure is reasonable in design, is simple in processing technology, has safe and reliable performances, and improves the production efficiency; and the steel wire rope abrasion-resistant carrier roller for the gantry crane is easy to operate, is high in practicability, and is obvious in application effects.
Description
Technical field
The utility model relates to a kind of Steel cable pulley, particularly a kind of wire rope wear-resistant carrier roller for gantry crane.
Background technique
At present, the Steel cable pulley that gantry crane uses is generally roller type or is the nylon support-board type; The roller type carrying roller is ball bearing because of what use, anti-impact force is little, easily distortion, finally cause carrier roller stuck because of the bending shaft distortion, become static friction by rolling friction between wire rope and carrier roller like this, after a period of time, just formed deep groove on the carrier roller surface, accelerated the damage of wire rope and carrying roller, using effect is very undesirable.Nylon support-board type carrying roller, be exactly static friction fully in addition, although protected to a certain extent wire rope; but nylon material wears no resistance; basically use about half a year and must change, maintenance cost and frequency of maintenance increase on the contrary, will bring the tremendous economic loss to enterprise.
Therefore, providing a kind of simple in structure, reasonable in design, performance safety to be used for reliably the wire rope wear-resistant carrier roller of gantry crane, is one of these those skilled in the art problem that should address.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, reasonable in design, performance safety is reliable, applicability is strong is used for the wire rope wear-resistant carrier roller of gantry crane.
The technological scheme that adopts of the utility model is for achieving the above object: a kind of wire rope wear-resistant carrier roller for gantry crane is characterized in that this carrying roller comprises wheel hub and bearing; Wheel hub both sides correspondence is provided with bearing, is provided with coating in the groove at ring wheel hub center.
The described bearing outside is provided with gland.
Bearing adopts the rolling-rod type bearing.
The beneficial effects of the utility model are: the wire rope wear-resistant carrier roller wheel that is used for gantry crane that is provided with polyurethane coating reduces steel rope abrasion intensity, prevents that wire rope is because being subjected to for a long time external force friction fracture of wire to shorten its working life; Effectively extend the working life of carrying roller, greatly save Cost of repair and maintenance.This reasonable in design, processing technology is simple, and performance safety is reliable, has improved manufacturing efficiency; Simple to operate, practical, effect is remarkable.
Description of drawings
Fig. 1 is the utility model structural representation;
In figure: 1 wheel hub, 2 bearings, 3 grooves, 4 glands, 5 coatings.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:
Referring to Fig. 1, a kind of wire rope wear-resistant carrier roller for gantry crane, this carrying roller comprises wheel hub 1 and bearing 2; Wheel hub 1 both sides correspondence is provided with bearing 2, is provided with coating 5 in the groove 3 at ring wheel hub 1 center.
Described bearing 2 outsides are provided with gland 4, guarantee bearing without sideshake, good operation.
Wheel hub 1 adopts steel wheel hub, and is measure-alike with door machine initial designs, guarantees structural strength, the convenient installation.
Bearing 2 adopts rolling-rod type, and model: 80208 anti-impact forces are strong, guarantee to operate steadily.
The groove 3 at ring wheel hub 1 center guarantees that wire rope is along correct track smooth running, without lateral sliding.
Coating 5 is urethane rubber, plays wear-resisting, corrosion-resistant, Anti-impact shock-absorbing effect.
Coating 5 adopts pouring polyurethane rubber (CPU), is a kind of artificial synthetic engineering material, and its mechanical property is between rubber and engineering plastics, and the rigidity of existing engineering plastics and mechanical strength have again elasticity within the specific limits.In addition, different molecular chain structures can be formed with material behavior targetedly.The performance that the urethane rubber that uses on Steel cable pulley is mainly used is; Friction factor is little, wear-resisting property is excellent, good corrosion resistance, have unique shock resistance shock-absorbing capacity.
Design parameter is as follows:
| Friction factor | 0.1 |
| Hardness (shoreA) | 90-92 |
| 300% Young's modulus (Mpa) | 12 |
| Tensile breaking strength (Mpa) | 53 |
| Elongation percentage (%) | 500 |
| Tear strength (kg/cm 2) | 79 |
| Akron abrasion (cm 3/1.6km) | <0.05 |
| Compression set (%) | 26 |
| Oil resistant weight rate (46# machine oil, 23 ℃ of x72h) | <1.0 |
Through practical application, be provided with the wire rope wear-resistant carrier roller surface smoothing that is used for gantry crane of polyurethane coating, almost there is no wear trace.
Above-mentionedly with reference to embodiment, wire rope wear-resistant carrier roller that this is used for gantry crane is described in detail; illustrative rather than determinate; therefore in the variation and the modification that do not break away under the utility model general plotting, within should belonging to protection domain of the present utility model.
