Description
Technical field
The utility model relates to shore container cranes and bulk handling machineries, hard more specifically to a kind of full rope groove
Spend wear-resistant pulley.
Background technique
Pulley is essential components on hoisting machinery, in recent years about rope race occur impression, abrasion show
As at home and abroad harbour happens occasionally.
Current pulley is broadly divided into according to manufacturing process：Pulley, ring rolling pulley, monobloc forging pulley, Hot-Rolled Sheave are cast, no
By which kind of form, the hardness at rope groove position be mainly after passing through pulley monolithic molding to rope groove position carry out the quenching of part+
Tempering is to generate.But it is often limited to equipment in this way, it is merely able to guarantee that rope groove bottom or part reach hardness requirement.
Utility model content
In view of the above defects of the prior art, the purpose of the utility model is to provide a kind of full rope groove hardness is wear-resisting
Pulley solves the technical problem that impression, abrasion occurs in rope race, improves pulley service life, reduces later maintenance
And the cost of replacement.
To achieve the above object, the utility model adopts the following technical solution：
A kind of full rope groove hardness wear-resistant pulley, the pulley, including：Concentric be arranged and successively connect outward wheel hub,
Disc and wheel rim uniformly offer several lightening holes on the disc, gusset are equipped between two neighboring lightening hole, gusset
With a thickness of 20 ± 1mm, the wall thickness of the wheel rim is 20 ± 1mm, and rope groove is offered on wheel rim, and the bottom diameter of rope groove is 1800 ± 1mm,
The hardness of rope groove is HB300-400, and welding manner connection is all made of between the wheel hub, disc and wheel rim.
The wheel rim is 35# steel material.
The disc is Q345B steel plate material, with a thickness of 30 ± 1mm.
The wheel hub is 20# steel material.
The gusset is equipped with 8 pieces, is Q345B steel plate material, with a thickness of 20 ± 1mm.
The lightening hole is set to 8, and diameter is 100 ± 1mm.
In the above technical solution, a kind of full rope groove hardness wear-resistant pulley provided by the utility model, so that pulley
Overall construction design it is relatively light and handy, to reduce the own wt of pulley, while also improving the service life of pulley, with
And reduce cost to pulley later maintenance and replacement.By taking the matched pulley of 800T ship unloaders as an example, maintenance replacement every time can
About 630,000 yuan of saving expense.
