  1 Replacement of drive belt   V-belts should be replaced in time after failure. If multiple V-belts are used in combination, if one or part of them is in effect, the others should be replaced at the same time. New and old belts cannot be used together.   2 Handling of drive belt    Before installation, first check whether the driving wheel, passive wheel and tension wheel are on a flat surface. Generally speaking, when the center distance between the two pulleys is less than 1 meter, the allowable deviation is 2-3 mm, and when the center distance is greater than 1 meter, the allowable deviation is 3-4 mm. If the deviation is too large, it should be adjusted to meet the requirements before installation and tensioning. When loading and unloading, the tensioning wheel should be loosened first, or the endless variable speed wheel disc should be removed first, and then the belt should be installed or removed.   When the new V-belt is too tight to be loaded and unloaded, you should first remove a pulley, put on or remove the V-belt, and then install the pulley. Generally, the V-belt of the joint group should be removed after the pulley is removed.  3 Tensioning of drive belt    The tension of the transmission belt is adjusted by the tensioning wheel. If the belt is too tight, the belt will be seriously worn, and if it is too loose, it will be easy to slip, and the triangle belt will be seriously worn or even burned. Generally, when the distance between the two wheels is about 1 meter, use your fingers to press the middle of the triangle belt, and it should drop 10-20 mm vertically. The tension of the V-belt should be checked during use of the belt and adjusted at any time.   4 Replacement of drive pulley   During the operation, the pulley may be deformed, cracked, bearing wear or key loosening, peripheral hole wear, etc., and related parts should be repaired or replaced in time. When maintaining the harvester after the end of each season, the triangle belt should be removed and hung in a ventilated and dry place, or the tension wheel should be loosened to leave the belt in a slack state.   5 Cleaning of transmission belt    The triangle belt is easy to slip and accelerate the damage of the triangle belt when it is stained with grease and oil. It should be cleaned with gasoline in time, and it can also be cleaned with alkaline water and other cleaning agents.   6 Working temperature of transmission belt    The working temperature of the V-belt should generally not exceed 60°C. The test method is: after stopping the work, immediately touch the V-belt with your hand. If the hand stays on it for 1 minute without feeling very hot, the temperature is not high. If it is so hot that it cannot be parked for 1 minute, it means that the temperature is too high, and the cause should be identified and eliminated in time.
