Improvement of roller and roller bearing
Clicks:14363 Date:4-7
1, we support the rotational resistance and the quality of the roller bearing and seal in the assembly when placed in a certain amount of grease.
1, support the rotational resistance of roller, roller bearing and its sealing quality in the assembly when placed in a certain amount of grease, so sticky force roller rotates in the experimental rotational resistance from all in the bearing grease, when the roller is in normal use with grease lubricated bearings more prolong the life but the inferior roller in order to reduce the cost at the time of assembly, put less or not put in the care process and use of grease, the inadequate lubrication roller life is greatly reduced.
2, should pay attention to the quality of the roller tube, the roller special welding straight pipe should be uniform wall thickness, and no modification of pitting, after the car should be free of weld grooves or convex marks, the welding surface error free surface cracks and other defects.
3, TD75 type seal, the sealing effect is generally less than DT type TD75 type sealing seal, so more stringent assembly, sealing cover and the bearing seat not not concentric sealing phenomenon outside the side of a greater gap, the external dust, water more easily into the internal sealing roller.
Present situation and improvement measures of roller bearing
From the use of belt conveyor roller for many years in the investigation, water, dust will cause fatal damage to the roller. Roller bearing is the key component of the conveyor roller bearing, once damaged, will cause the roller rotation is not flexible or locked, so that the roller wear intensifies, the production efficiency is greatly reduced. Theoretically, the transmission of the labyrinth design as long as the water and dust according to the principle of a force to cut off the leakage path, you can make it lubrication, so that the situation is not flexible to improve. Therefore, it is urgent to find a seal structure with simple structure and reliable sealing effect.
According to the utility model, the existing three sealing structure can effectively prevent water and dust. This structure can maximize the use of the original production process and structure, and can reduce production costs. The principle is based on the traditional labyrinth seal to increase the cushion dust and additional seal. Among them, the cushion seal for waterproof, additional seal for dust.
In order to more effectively enhance the sealing effect, reduce leakage, ensure that the seal is durable and reliable, need to be targeted to take certain plugging measures. In the manufacturing and assembly process, to be as close as possible to the appropriate amount of butter before assembly.
The other structure can be made of super high molecular weight polyethylene material to seal the inner and outer cover, which can reduce the number of parts, save the cost of mould manufacturing, and improve the labor productivity.
In the conveying operation, idler shaft short because of the long-term operation of heating, easy deformation, and long-term high temperature grease, easy failure, dry, can consider the use of metal bearing made of ceramic materials, such as carbide based metal ceramic bearings made of this material and the sealing ring has high hardness, high wear resistance, high temperature resistance etc., can prolong the service time of roller bearing.
Since the two ends of the shaft head are in operation, the oil nozzle can be designed and added, and the lubricating grease can be added when the equipment is repaired.
On the other hand, in order to solve the roller operation condition of death card does not turn or locking problems, consider the existing structure of the roller bearing with the transformation, new materials have mature application of ultra high molecular weight polyethylene manufacturing. The bearing made of the material has self-lubricating property, no need of sealing, and the structure can be simplified. The bearing seat and the supporting roller tube body are tightly matched with each other. After the roller bearing test data show that this structure has the advantages of low manufacturing cost, no need of lubrication, greatly eliminating dead roller transferred, and wear resistance and high temperature resistance are improved, the process can realize large-scale production, to adapt to modern production requirements of conveying machine.
