Under the premise of overall transport, the guide wheel and the fixed wheel adopt the integral cast-welded structure. The hub and the rim are cast steel materials, the spokes are channel steel, and the whole annealing is performed after welding.
Considering that the replacement of the bearing bush is convenient to maintain, there is room for replacement of the bearing bush, and the structure of the guide wheel device adopts an eccentric arrangement.
The guide axle is integrally forged with medium carbon alloy steel. The caster is welded with a PVC or nylon gasket to protect the wire rope.
Imported (or domestic) spherical roller bearings can be used, and bearing temperature measuring components can also be installed.
In order to extend the service life of the wire rope, the rim is provided with a wear-resistant, pressure-resistant wedge-shaped gasket, which is padded with D660 (or nylon 1010).
1) Eccentric arrangement: There is a disassembly and assembly space for replacing the bearing bush on the side of the swimming wheel, and only the bearing bush can be repaired and replaced without disassembling the entire day wheel device.
2) Symmetrical arrangement: the four wheels are symmetrical with respect to both sides of the two bearing seats. Once the bearing pads need to be replaced, only the entire day wheel device can be disassembled.

There are basically two types of structures for the sky wheel & guide wheel: one is a spoke type structure and the other is a welded structure. The former is an old-fashioned structure, and the overall rigidity is poor, and the spokes are easily broken during use. The rope groove liner is made of hardwood material that is subject to wear, frequent replacement, and produces an audible sound during operation. The inner diameter of the swimming wheel is inlaid with a bearing bush. The rotating mating surface is lubricated for the grease of the oil cup. After a certain period of time, the grease deteriorates and the oil passage is blocked. The oil passage is blocked, which is not conducive to relubrication. The bearing bush is cast iron material, easy to wear and pressure. Crack, maintenance workload is large.

The welding type has been improved in structure to improve the overall strength. The rope groove liner is made of wear-resistant engineering plastics, which prolongs the service life. The bearing bush is made of high-quality brass material, the lubrication method is lubricated with thin oil, and the oil cup is shifted to The outer side of the wheel is used to facilitate daily oiling operations.

Sky wheel and guide wheel common faults and technology

1) For the old structure of the Tianlun sliding bearing burning tile problem, the lubrication method should be improved; because the sky wheel is installed on the , the daily maintenance is inconvenient, the temperature alarm signal device should be added to timely maintain the anti-burning accident, or the original sliding bearing Replacement with rolling bearing structure

2) For the old structure of the rope groove without padding, no additional padding can be added to the original rope groove. A padded sky wheel needs to be replaced. The adjacent assembly size can be kept still for installation.

3) For mines with difficult mountain transportation difficulties or difficult transportation in underground roadways, the sky wheel (guide wheel) can be replaced with a two-half structure or a four-half structure
