Classification and analysis of the coupling of belt conveyor

Classification analysis of belt conveyor couplings Classification analysis of belt conveyor couplings Classification analysis of belt loading conveyor couplings Such couplings include sleeve type, sandwich type, flange type, etc. . Belt loading conveyor has the advantages of large conveying capacity, simple structure, convenient maintenance, standardized parts, etc. It is widely used in mining, metallurgy (content: extracting metals or metal compounds from ore), coal and other industries to transport loose materials or finished parts Articles, according to the requirements of the conveying process, can be conveyed by a single unit, or composed of multiple units or combined with other conveying equipment to form a horizontal or inclined conveying system to meet the needs of different layout types of operation lines. It is suitable for conveying bulk density (unit: g/ cm3 or kg/m3) is less than 1.67/ton/m3, easy to take out powder, granular, small lumps of low-abrasive materials and bagged materials, such as coal, gravel, sand, cement (material: powder Shape hydraulic inorganic cementitious materials), fertilizers, grains, etc. The temperature of the delivered material is less than 60°C. The captain and assembly form can be determined according to user requirements, and the drive can be an electric drum or a drive device with a drive frame. Flange coupling is a combination of two flanged half couplings used to transmit motion and torque. The material of the flange coupling can be gray cast iron or carbon (C) plain steel, which lacks the ability to compensate the relative displacement of the two shafts, so the neutrality of the two shafts is very high. When there is relative displacement between the two axes, the machine tool will generate additional load, which will deteriorate its working conditions, which is its main disadvantage. However, due to its simple structure, low cost, and large torque, it is often used in occasions with low speed, no impact, high shaft rigidity and good neutrality. The reason for the flexible coupling 1, the flexible coupling with non-elastic elements, is that it is flexible, so it can compensate for the relative displacement of the two shafts. However, due to the lack of elastic elements, it cannot cushion and reduce vibration. The following types are commonly used: Cross-slider couplings are composed of half couplings with grooves on the end and intermediate discs with protruding teeth on both sides. The protruding teeth can slide in the groove, thereby compensating for the relative displacement between the two shafts during installation and operation. The mating part is made of 45 steel, and its working surface must be heat treated to increase its hardness. When the requirement is low, Q275 steel can also be used without heat treatment. Belt conveyors include universal mobile type, underground selection type, fixed type for open-pit mines, special structure type, removable conveyor, special transfer function type for loaders, large inclination conveyors, etc. Generally speaking, short-distance in-plant conveyors can be used To complete horizontal, upward or downward transportation, the reversible pattern belt conveyor can be used to convey materials in both directions. In order to reduce friction and wear (a basic type of component failure), oil should be injected into the oil hole of the middle plate for lubrication. Since the half-coupling and the intermediate disc form a kinematic pair and will not rotate relative to each other, the angular velocity of the driving shaft and the driven shaft should be equal. However, when there is a relative displacement between the two shafts, the middle disk will generate a large centrifugal force, thereby increasing dynamic load and wear (a basic type of component failure), so it should be noted that its working speed should not exceed the specified value. The middle sliding block can also be made of nylon, and a small amount of graphite (chemical formula C) or molybdenum disulfide (MoS2) can be added to make it self-lubricating during use. This kind of coupling has the advantages of simple structure and small size, and is suitable for low power (referring to how much work an object does in a unit time), high speed, and no serious impact. Mesh belt conveyor transportation machinery can not only complete the transportation of bulk materials, but also transport finished materials, but depending on the place of use, working environment, and the type of materials to be conveyed, there will be big differences in its design and application. The basic working principle of the tunnel drying oven: under the monitoring of the computer system, the bottles are transported by the conveyor belt into the preheating zone, high temperature sterilization zone and low temperature cooling zone of the tunnel sterilization oven. The loading conveyor belt speed is steplessly adjustable, and the temperature monitoring system is set to have no paper or paper records. The whole process is always under the protection of one hundred levels of laminar flow.
