Head sheave and deflector sheave
Head sheave and deflector sheave are mainly in two structures: one is spoke-type structure, the other is welded-type structure.
The former is traditional structure, with poor overall rigidity, easily broken of spoke during operation. The pad of rope groove uses hardwood materials, easily abraded and frequently replaced, with noise during operation. Inner diameter of traveling sheave is lined with bearing bush, and rotating fitting surface is lubricated using lubricating grease in grease cup, which will turn metamorphic and dry after certain time in service, and the grease-discharging pipe will be clogged; it will hamper the refilling of grease for lubrication. The bearing bush is cast iron material, easily abraded and fractured, which requires great workload of maintenance.
At present , Ouo company mainly design and manufacture the welded-type head sheave.The welded type has made improvement on the structure and overall strength, the liner of rope groove adopts wear-resistant engineering plastic-K-09 sheave liner to extend service life, and the bearing bush adopts high-quality material of brass. Lubricating method adopts thin oil for lubrication, and oil cup shall be re-located onto the outer circle side of traveling sheave to provide convenience for daily operation of oil filling.
We can customize 1m-6m head sheave and deflector sheave.
