The installation and maintenance of the V-belt for agricultural machinery is critical to avoiding damage to the belt and bearings and the transmission speed. The choice of the V-belt model is determined by the speed of the delivered power tape, and there is a lot of knowledge in it. Next, we follow the Agricultural Belt Supplierto find out:
1 Select the correct model The selected model should be compatible with the selected V-belt, otherwise the V-belt will be abnormal in the pulley groove. When changing to a V-belt, it is best to bring the old belt to the agricultural machinery department for purchase, in case the model is mistaken.
2 Before the correct installation, if the center distance between the two shafts is adjustable, the center distance should be shortened first, and the center distance should be adjusted as required after the tape is installed; if the center distance between the two shafts is not adjustable, you can Put a V-belt into the groove of the wheel first, and then turn another pulley to install the V-belt. Use the same method to install all the V-belts. It is forbidden to use tools to pry or pull the V-belt to prevent the V-belt from stretching or being too tight.
3 To prevent the installation of belt pulleys in the string groove, the centers of the two upper pulleys must be aligned, otherwise it will cause the Agricultural V-Belt to work on one side, severe wear, and reduce the service life of the V-belt.
4 The tightness of the suitable V-belt must be checked and adjusted frequently to make it meet the requirements. Too loose the V-belt will not only easily slip, but also increase the wear of the V-belt, and even fail to transmit power. Too tight will not only cause the V-belt to elongate and deform and be easily damaged, but also cause excessive force on the engine main bearing and clutch bearing. And accelerate the wear of the V-belt. The correct inspection method is: apply a vertical pressure of about 2 kg to the middle of each tape by hand, and the appropriate sink amount is 20-30 mm. If it is not suitable, adjust it in time.
5 New and old non-mixed double or more than three V-belts need to be replaced, the specified type of V-Belt should be selected, and the tightness of each group of V-belts must be consistent. It is not allowed to mix the new and the old or reduce the number of V-belts. Otherwise, the old and new V-belts will be affected. Uneven force, even the old V-belt does not work, affecting power transmission and shortening the life of the V-belt.
6 Strictly prevent contamination. In use, strictly prevent the V-belt from oil and muddy water, and avoid contact with corrosive substances such as acids and alkalis to prevent slipping and corrosion of the V-belt and early damage.
7 Daily maintenance operators and users should master the correct operation essentials in normal driving, and according to the technical requirements of the instruction manual, try to avoid sudden starts and sudden braking; also prevent frequent overloading; remove the triangle when the machine is out of use for a long time The belt is stored separately.
V-belts are widely used in agricultural machinery. The standardized V-belt has a trapezoidal cross-section with no joints in the entire circle. It is divided into 7 types: O-type, A-type, B-type, C-type, D-type, E-type, and F-type. The cross-sectional area of the triangular-belt gradually changes from O-type to F-type. Increase. Scientific selection of agricultural machinery triangle belt can speed up the operation of agricultural machinery.
