Agricultural Machinery Triangle Selection Learning
Triangle tape is widely used in agricultural machinery. The standardized triangular section is trapezoidal in shape. There are no joints in the entire circle and there are seven types of O-type, A-type, B-type, C-type, D-type, E-type and F-type models. The sectional area of ​​the tape from O-type to F-type gradually increases. Big. The choice of tape model is based on the speed of the power tape delivered. There are a lot of knowledge in this area. The model selected for the selected model should be compatible with the selected triangular tape, otherwise the triangular tape will appear abnormal in the pulley groove. When replacing the triangular tape, it is best to bring the old tape to the agricultural machinery department to avoid the model number. Wrong. Before installation and installation, if the center distance between two axes is an adjustable structure, the center distance should be shortened first. After the tape is installed, the center distance should be adjusted as required; if the center distance between two axes is not adjustable, one can be used. The V-belt is inserted into the wheel slot first, then the other pulley is rotated, the triangular tape is mounted, and a set of triangular tapes are mounted in the same way. It is forbidden to use hard boring and hard boring on the triangle belt during installation to prevent the triangle tape from being stretched or over-tightened. To prevent the skewer from installing the pulleys, the centers of the two upper pulleys must be aligned. Otherwise, the triangular tapes will work unilaterally, which will cause serious wear and reduce the service life of the triangular tapes. Elasticity The tightness of the triangular tape must always be checked and adjusted to meet the requirements. Triangular belt is not only easy to slip, but also increase the wear of the triangle belt, and even can not transmit power; too tight, not only will make the V-belt elongated deformation easily damaged, but also cause the clutch bearings of the engine main bearing due to excessive force, and Accelerate the wear of the triangle belt. The correct inspection method is: Apply a vertical pressure of about 2 kg in the center of each tape by hand, and the amount of sinking is (20--30) mm. If it is not suitable, adjust it in time. When old or new molybdenum double or three or more triangular tapes need to be replaced, use the specified type of triangle tape and require that each set of triangle tapes have the same degree of tightness, no new or old mixed packing or reduced number of roots. Otherwise, the old and new triangular belts are stressed. Uneven, even the old triangle belt does not work, affecting power transmission and shortening the life of the V-belt. Strictly prevent the use of pollution in the triangle belt to prevent oil pollution and muddy water, to avoid contact with acids, alkalis and other corrosive substances, to prevent slipping and corrosion of the V-belt and early damage. Routine maintenance drivers and users must master the correct operation essentials during normal driving. In accordance with the technical requirements of the instruction manual, they should avoid sudden start-up and sudden braking: they should also be prevented from constantly overloading; long-term use of the machine tool should remove the triangle tape alone.
