This utility model one high intensity rope sheave, compared with prior art has the advantage that
First, this high intensity rope sheave make described wheel body install many steel wire ropes by arranging multiple described grooving simultaneously,
To improve its ability installing coupling.By arranging certain interval between adjacent described grooving partly in order to install
Many steel wire ropes the most dry around, be on the other hand the wear resistance strengthening described grooving.By arranging described casting hole not only
Making the demoulding in described rope sheave production process be more prone to, also making can be by described casting when high intensity rope sheave described in processing and manufacturing
Described wheel body is fixed on machining tool by pore-creating, reduces the fixing difficulty of described wheel body；In addition, this design also makes institute
The weight stating wheel body is substantially reduced, thus reduces steel wire rope load during elevator lifting, in case occurring because of long-time
Load is excessive and the situation of fracture occurs, is effectively increased the service life of steel wire rope, and then makes people take elevator to make peace
Overall coefficient is improved.Described wheel body self can be effectively improved by arranging enhancing muscle between equally distributed described casting hole
Mechanical strength, be additionally up to HB200-250 because of the hardness of described wheel body, thus this wheel body under great stress effect time also
Will not deform upon easily, this feature gives the weight capacity that described wheel body is high.
Second, the quantity of grooving described in this high intensity rope sheave is 7-9.This design makes can be wound around on described wheel body 7-9
Root steel wire rope, this provides sufficient steel wire rope installation site for elevator in installation process, and beneficially elevator installation operations is smooth
Implement.
3rd, described in this high intensity rope sheave, the degree of depth of grooving is 4.0-5.5mm.This design is to make described grooving energy
Enough accommodate the steel wire rope of sufficiently large diameter.Could give steel wire rope sufficiently high tension because only that the diameter of steel wire rope is sufficiently large
Cutting capacity, only steel wire rope have sufficiently high tension cutting capacity guarantee people will not fall ladder thing when taking elevator
Part, could be that the life security of people provides safeguard.
