Description
Technical Field
The utility model relates to the field of elevator components, in particular to a rope pulley structure for an elevator.
Background
Sheaves are conventional components in elevator systems that primarily guide and pull the ropes, which bear radial loads from the ropes, requiring stable and balanced force performance; the existing rope wheel structure spoke structure is simpler in design, the bearing capacity of the rope wheel and the uniform distribution of loads in the circumferential direction are improved mainly by increasing the sectional area of the spoke or the number of the spoke, but the dead weight and the cost of the rope wheel are obviously increased by the mode, and the casting and processing difficulty is increased.
Disclosure of Invention
The utility model provides a rope pulley structure for an elevator, and aims to solve the problems of simple rope pulley spoke structure, high dead weight, high cost and high processing difficulty.
The technical scheme that it solved includes wheel hub and concentric and be located annular collar of wheel hub with wheel hub, thereby the collar is used for installing on the epaxial with the bearing cooperation, and thereby the outer wall of wheel hub is opened has annular rope groove, and circumference equipartition has the spoke of a plurality of Y types between wheel hub and the collar, and two bifurcation of the head of spoke all are connected with wheel hub inner wall, and the afterbody and the outer wall connection of collar of spoke.
The rope grooves are arranged on the outer wall of the hub in parallel along the axial direction, and the rope grooves are symmetrically arranged about the axial midpoint of the hub.
Reinforcing ribs are arranged on two sides of each spoke.
The tail part and the two forked head parts of the spoke are respectively provided with an auxiliary supporting ear extending along the axial direction of the hub, and the auxiliary supporting ears are connected with the hub and the spoke end parts or the mounting ring and the spoke end parts in a smooth transition manner.
The spokes of the utility model have more supporting points on the hub, the stress of the hub of the rope wheel is uniform and stable, the weight and the material consumption of the rope wheel are greatly reduced, and the processing performance is good.
Drawings
Fig. 1 is a front view of the present utility model, wherein triangles are spoke stress diagrams.
Fig. 2 is a left side cross-sectional view of the present utility model.
Detailed Description
With reference to the attached drawings, the novel hub comprises a hub 1 and an annular mounting ring 2 positioned in the center of the hub 1, wherein the mounting ring 2 is used for being matched with a bearing so as to be mounted on a shaft, an annular rope groove 3 is formed in the outer wall of the hub 1 and is used for bearing a steel wire rope and axially limiting the steel wire rope, a plurality of Y-shaped spokes 4 are uniformly distributed between the hub 1 and the mounting ring 2 in the circumference, two branches of the head of each spoke 4 are connected with the inner wall of the hub 1, the tail of each spoke 4 is connected with the outer wall of the mounting ring 2, and the hub 1 is supported by the spokes 4.
The rope grooves 3 are arranged on the outer wall of the hub 1 side by side along the axial direction, so that a plurality of steel wires can be borne at the same time, and the rope grooves 3 are symmetrically arranged about the axial midpoint of the hub 1, so that the stress balance of the hub 1 is ensured.
The two sides of the spoke 4 are provided with reinforcing ribs 5, so that the stress intensity of the spoke is improved.
The tail parts of the spokes 4 and the head parts of the two branches are respectively provided with an auxiliary supporting lug 6 extending along the axial direction of the hub 1, the auxiliary supporting lugs 6 are in smooth transition connection with the end parts of the hub 1 and the spokes 4 or the end parts of the mounting ring 2 and the spokes 4, and the auxiliary supporting lugs 6 can promote the axial supporting force of the spokes 4 on the hub 1 and are beneficial to the uniform dispersion of the stress of the hub 1 in the axial direction.
The utility model can bear a plurality of steel wire ropes at the same time, the Y-shaped spokes 4 are stressed in a triangle, the stress is more stable, the Y-shaped spokes can bear larger constant load and impact load, two branches at the heads of the Y-shaped spokes 4 are uniformly distributed at the inner side of the hub 1, the support points connected with the rim are more, the support positions of the hub 1 are more dense, the support stress area is larger, and the radial force borne by the hub 1 is uniformly dispersed.
The spoke 4 of the type is designed, so that the weight and the material consumption of the rope wheel are greatly reduced, compared with the original rope wheel, the weight of the rope wheel is saved by more than 50%, the machining allowance is small, the overall cost is reduced by more than 50%, and the rope wheel has obvious cost advantages.
The rope wheel casting process of the structure has good performance and higher qualification rate, and is not easy to cause sand holes, loose and meat-lack casting defects.
The rope wheel material adopts ductile iron (QT 600-10, QT 450), has high strength, medium toughness and plasticity, higher comprehensive performance and good wear resistance and vibration damping performance.
