As the name implies, industrial belts are belts used in industry, also known as transmission belts. Compared with gear transmissions and chain transmissions, industrial belt transmissions have the advantages of simple mechanism, low noise and low equipment cost. They are widely used in motors and internal combustion engine driven machinery and Power transmission on equipment.   1 Classification according to belt core structure: A. Cord core: belt with cord as the strong layer. B. Rope core: belt with rope as the strong layer.    2 Classification according to the purpose of the transmission belt: A. Industrial belt: used as a transmission belt on industrial and mining machinery. B. Automobile belt: a transmission belt dedicated to internal combustion engines such as automobiles and tractors. C. Agricultural machinery belt: a belt specially used for working machinery of agricultural machinery such as harvesters. D. Variable speed belt: It is used in conjunction with a pulley with variable pitch diameter, which can continuously change the transmission ratio within a fixed range, and its relative height is generally below 0.5. E. Light load belt: belt used for low power transmission. F. Electrostatically conductive belt: a belt with electrostatic conductivity.   3 Classification according to the structure of the belt: A, cloth type: belt with cloth covered on the outer layer. B. Trimming type: a belt with a cut surface on the side (that is, without wrapping). Industrial belt storage:   1 The temperature of the warehouse should be kept between -15 and 40 degrees Celsius during storage, and the relative humidity should be kept between 50% and 80%.   2 Industrial belts and pulleys should be kept clean and free of oil and water.   3 Never install tools or external forces on the belt directly when installing the belt.   4 When installing the belt, you should check the transmission system, whether the transmission shaft is perpendicular to the transmission wheel, whether the transmission shaft is parallel, whether the transmission wheel is on a plane, if not, it should be corrected.    5. Do not stick grease or other chemicals on the belt   6 During storage and transportation, avoid direct sunlight or rain and snow, keep clean, and prevent contact with acid and alkali oils and organic solvents and other substances that affect the quality of rubber   7 During storage, avoid deforming the belt under excessive weight to prevent mechanical damage. Do not bend or squeeze too much.    Industrial belt joint bonding method: 1. Mechanical joints, one refers to the use of industrial belt buckle joints. This joint method is convenient, convenient, and relatively economical. If the belt is damaged during use, this belt buckle joint is easy to replace when you want to replace a new belt. However, the efficiency of the joint is low and easily damaged, which has a certain impact on the service life of the conveyor belt products. 2. Cold bonding head, that is, the method of using cold adhesive to connect the joints, using adhesive as the raw material to connect the two ends of the conveyor belt, the key to the cold bonding effect depends on the glue used, whether it is done or not Stitching. Because this method has the advantages of high joint strength, no noise, no vibration, simple operation, and short joint time, it has a wide range of applications, but from a practical point of view, because the process conditions are more difficult to master, the The quality has a great influence on the joint, so it is not very stable. In addition, the cold-adhesive conveyor belt is not suitable for wet and temperature-sensitive materials.    3. Hot vulcanization joint, the conveyor belt interface of the hot vulcanization joint is completely closed, not easy to be wet by water. The process of industrial belt vulcanization joint is generally to place the lower frame of the vulcanizer on the industrial belt frame, the two ends are aligned, and then put the water pressure plate, small heat insulation plate, lower heat insulation plate, two sides of the two vulcanizers in sequence Install the platforms of 1-2 meters each and fix them. The upper surface of the platform should be flush with the surface of the lower heating plate or slightly lower. At the same time, it must not affect the tension of the tie rod. Put the two joints of the belt on the platform to start vulcanization. . This method is the most ideal joint method at present. It can ensure high joint efficiency, and it is also very stable. The joint life is also very long and easy to master. However, the hot vulcanized joint process is more complicated and requires high personnel. Cold bonding process Simple short-term training is available.
