Abstract
The utility model provides an elevator lift/lower machine copper clad steel worm wheel, an elevator lift/lower machine copper clad steel worm wheel, it is main includes one kind is used high quality carbon structural steel to personally experience sth. Part of the body as the disc worm wheel of base member, the worm wheel body has the hub in keyway shaft hole and combines to become integrative spoke with middle hub and outer lane rim including rim, the centre of outer lane, the excircle surface of rim is provided with the turbine tooth and on the surface casting one deck copper alloy layer of turbine tooth and constitute the bimetal worm wheel body, the molten condition is personally submitted in the turbine tooth on rim excircle surface and the combination on copper alloy layer, the little 4 -6mm of root diameter of faying face diameter ratio turbine tooth, it has simple structure, and convenient to use is reliable, characteristics such as the bearing capacity is big, the maintenance period is long, stand wear and tear, longe -lived.
Description
Technical field
The copper covered steel worm gear relating to a kind of elevator hoisting machine of the present utility model, is mainly used in the elevator hoisting machine product such as van-type passenger elevators and stair type elevator, speedwalk, the technical field of transmission of the elevator hoisting machine belonged to.
Background technology
Traditional worm gear in elevator hoisting machine is to use monoblock type cast copper alloy materials processing to form, and this material not only manufacturing cost is high, simultaneously as the compactness of copper casting is poor, loose even sand holes or pore easily occurs；Furthermore the physical and mechanical properties of cast copper alloy material is poor, particularly bearing capacity and anti-impact force is poor, cause its structural strength undesirable, because elevator hoisting machine lifting variation is frequently, worm gear operating often rises for a long time under positive and negative duty, brakes or descending, braking, and the impulsive force making the keyway on worm gear shell bear frequently occurs, and causes the key on keyway and elevator main shaft slowly to occur loosening, until key damage, affect the normal operation of elevator.This situation once occurs, it is necessary to shut down and change worm gear, so the worm gear quality of elevator hoisting machine is particularly important.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art to exist, and provides a kind of simple in construction, easy to use and reliable, and bearing capacity is big, maintenance period length, wear-resistant, the elevator hoisting machine copper covered steel worm gear of life-span length.
The purpose of this utility model completes by following technical solution, a kind of elevator hoisting machine copper covered steel worm gear, a kind of elevator hoisting machine copper covered steel worm gear, it mainly includes a kind of disc worm wheel body with carbon constructional quality steel as matrix, and described worm wheel body includes the wheel rim of outer ring, the middle hub with shaft with key way hole and the spoke being combined into one by middle hub with outer ring rim；The outer round surface of described wheel rim is provided with turbo tooth and at the surface of turbo tooth casting one layer of copper alloy layer constitute a bimetallic worm wheel body.
As preferably: the described turbo tooth of wheel rim outer round surface and the faying face of copper alloy layer are molten condition；Described faying face diameter 4-6mm less than the root diameter of turbo tooth.
This utility model has simple in construction, easy to use and reliable, the feature such as bearing capacity is big, maintenance period length, wear-resistant, life-span length.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the K-K sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail: Fig. 1, shown in 2, a kind of elevator hoisting machine copper covered steel worm gear described in the utility model, it mainly includes a kind of disc worm wheel body with carbon constructional quality steel as matrix, and described worm wheel body includes the wheel rim 5 of outer ring, the middle hub 3 with shaft with key way hole and the spoke 4 being combined into one by middle hub 3 with outer ring rim 5；The outer round surface of described wheel rim 5 is provided with turbo tooth 1 and at the surface of turbo tooth 1 casting one layer of copper alloy layer 2 constitute a bimetallic worm wheel body.
The turbo tooth 1 of wheel rim outer round surface described in the utility model and the faying face of copper alloy layer 2 are molten condition；Described worm-gear toothing 1 can use the centrifugal casting composite technology of nitrogen protection device to be fabricated by with the copper alloy layer 2 of outer surface.
The relative dimensions of the hub 3 of described worm wheel body, spoke 4 and wheel rim 5 can determine according to actual needs, the requirement of thickness worm-gear toothing the to be met processing of the copper alloy layer 2 combined with worm wheel body wheel rim, generally diameter 4mm～6mm less than worm wheel body root diameter of wormwheel of faying face, and form described elevator hoisting machine copper covered steel worm gear through Precision Machining.
