Mine Hoist Guide Wheel Device of Head Sheave Castings And Forgings
1. Product description of head sheavel castings and forgings On the premise that the guide wheel device can be transported as a whole, the traveling wheel and the fixed wheel adopt the whole casting welding structure. The wheel hub and rim are cast steel materials, and the spokes are channel steel. After welding, the whole annealing process can be carried out.
In consideration of the convenience of replacing the bearing bush for maintenance, there is room for replacing the bearing bush for disassembly, and the guide wheel device adopts eccentric arrangement. The guide wheel shaft is integral forged of medium carbon alloy steel, with cast-welded roof wheel, equipped with PVC or nylon liner to protect the wire rope. Imported (or domestic) spherical roller bearings, bearing temperature measuring elements can also be installed.
2. Product structure of crown wheel and guide wheel, castings and forgings There are basically two kinds of roof wheel & guide wheel structure: one is the spoke structure, the other is the welding structure. The former is the old structure, the overall rigidity is poor, spokes are easy to break in use. Rope groove liner is hardwood material, easy to wear, frequent replacement, and noise in operation. The inner diameter of the swimming wheel is inset with bearing bush, and the rotating mating surface is lubricated by grease in the oil cup. After a certain period of use, the grease will deteriorate and dry up, and the oil passage will be blocked, which is not conducive to lubrication again. The bearing bush is made of cast iron, which is easy to wear and fracture, and the maintenance workload is large.
The welded type is improved in structure to improve the overall strength, wear-resistant engineering plastics are used for the lining of the rope groove to prolong the service life, high-quality brass materials are used for the bearing bush, thin oil is used for lubrication, and the oil cup is moved to the outer circular side of the swimming wheel to facilitate the daily oil filling operation.
3. Product parameters of sheet-wheel and guide wheel, castings and forgings
4.Product features of Head sheaves castings and forgings In order to prolong the service life of the wire rope, the wheel rim is equipped with wear-resistant and pressure-resistant wedge liner, using D660 (or nylon 1010) liner.
(1) Eccentric arrangement: there is a disassembly and assembly space for replacing the bearing bush on one side of the swimming wheel, and only the maintenance and replacement of the bearing bush can be carried out without disassembling the whole sheet-wheel device.
(2) symmetrical arrangement: the four wheels are symmetrical relative to the two sides of the bearing seat, but the need to replace the bearing bush, can only be removed from the whole sheaf device.
