The standardized triangular section is trapezoidal in shape. There are no joints in the entire ring, which are divided into 7 types: O-type, A-type, B-type, C-type, D-type, E-type, and F-type. The sectional area of ​​the V-belt gradually extends from O-type to F-type. Increase. The triangular belt is widely used in agricultural machinery. The choice of the V-belt model is based on the speed of the power tape delivered. There are a lot of knowledge in this area.
1 The model chosen for the selected model should be compatible with the selected V-belt, otherwise the V-belt will appear abnormal in the pulley groove. When using a V-belt, it is best to bring the old belt to the farm machinery department to avoid mistakes in the model.
2 Correct installation Before 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 the two axes is not adjustable, one can be used. The root V-belt is first inserted into the wheel slot, and then the other pulley is rotated to mount the V-belt. In the same way, a set of V-belts are installed. 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.
3 When installing the pulleys with skewed grooves, the centers of the two upper pulleys must be aligned. Otherwise, the triangular belts will work unilaterally, causing serious wear and reducing the service life of the triangular belts.
4 Elastic Appropriateness The tightness of the V-belt 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 triangle belt stretch deformation, easy to damage, but also cause the engine main bearing and clutch bearing due to excessive force, And accelerate the wear of the V-belt. The correct inspection method is: hand in the middle of each tape, apply about 2 kg of vertical pressure, the amount of sinking is 20--30 mm is appropriate, when inappropriate, timely adjustment.
5 When the old and new molybdenum double or three or more triangular belts need to be replaced, the specified model of the triangle belt should be selected, and the tightness of each set of triangular belts should be the same, and the old and new mixed equipment must be used or the number of roots should be reduced. Otherwise, the old and new triangular belts are affected. Inequality, even the old triangle belt does not work, affecting power transmission and shortening the life of the V-belt.
6 Strictly prevent contamination Use strictly prevent oil and dirt in the V-belt, avoid contact with corrosive substances such as acids and alkalis to prevent slipping and corrosion of the V-belt and early damage.
7 Day-to-day maintenance The operator and the user must master the correct operation essentials during normal driving. In accordance with the technical requirements of the instruction manual, they should avoid sudden start and sudden braking; they should also prevent frequent overload operation; when the machine tool is decommissioned for a long time, the triangle should be removed. Stored separately.
