Belt news

What are the reasons for the break of the ordinary triangle belt?

1. After the belt core is used for a long time, the structure is destroyed.

2. The belt has poor resistance to stretching;

3. The belt has poor resistance to extrusion;

4. The quality of the belt is not good enough;

5. The lengths of the two belts are inconsistent and interfere with each other during operation.

How to use the endless conveyor belt correctly?

The endless conveyor belt is made into a jointless endless conveyor belt in the production process. It is characterized by no joints, no impact on the service life due to early damage of the joints, smooth surface of the tape and uniform tension, so the tape runs smoothly and the extension is used. The rate is small.

The endless belt will stretch during use, and part of it will be elastically stretched and will return to its original state after the external force is removed. In the common fabric core conveyor belt, the elongation of the EP conveyor belt is relatively small, the elongation of the NN conveyor belt is relatively large, and during use, the NN conveyor belt has a relatively large creep after the nylon fiber is stressed, so during use The elongation ratio is increased, and because of the creep of the fiber, the amount that can be shrunk back is much smaller than the elongation after the external force is removed.

V-belt model specifications and selection

V-belts are widely used in agricultural machinery. The standardized triangular belt has a trapezoidal cross section and no joints in the whole circle. It is divided into seven types: O-type, A-type, B-type, C-type, D-type, E-type and F-type. The cross-sectional area from the O-type to the F-type tape is gradually increased. Big. The four models SPZ, SPA, SPB, and SPC are V-belt narrow V-shaped, and the choice of tape model is determined by the speed of the transmitted tape.

Install correctly     

It is forbidden to use tools to harden and harden the timing belt during installation to prevent the triangle tape from being stretched or too loose. Preventing the groove: When installing the pulley, the center of the two upper pulleys must be aligned. Otherwise, the triangular tape will work on one side, causing serious wear and reducing the service life of the triangular tape. Elasticity: The tightness of the triangular tape must be checked and adjusted to meet the requirements. The loosening of the V-belt is not only easy to slip, but also increases the wear of the V-belt, and even does not transmit the power; too tight, not only will the V-belt be elongated and deformed, it is easy to damage, and it will also cause the clutch bearing of the main bearing of the engine to be excessively stressed. And accelerate the wear of the V-belt.

Before installation, if the center distance of the two shafts is adjustable, the center distance should be shortened first, and then the center distance should be adjusted as required after the tape is installed. If the center distance of the two axes is not adjustable, one can be combined. The belt is first inserted into the wheel groove, then the other pulley is rotated, the triangular tape is attached, and a set of triangular tape is attached in the same manner.

Correct inspection method

1. Apply 2 kg of vertical pressure to the middle of each tape by hand. The amount of sinking is (20-- 30) mm. If it is not suitable, adjust it in time.

2. Strictly prevent contamination: In use, it is necessary to strictly prevent the V-belt oil and muddy water from contacting with corrosive substances such as acid and alkali to prevent slipping and corrosion of the V-belt and early damage.

3. New and old Mo mix: When double or more than three pieces of triangular tape need to be replaced, the specified type of triangular tape should be selected, and the tightness of each set of triangular tape should be consistent. It is not allowed to mix new or old or reduce the number of roots. Otherwise, the old and new triangles The belt is unevenly stressed, even the old V-belt does not work, affecting the power transmission and shortening the life of the V-belt.

4. Daily maintenance: the driver and the user should master the correct operation essentials during normal driving. According to the technical requirements of the instruction manual, try to avoid violent start and sudden braking: it should also prevent frequent overloading; the machine should be removed after long-term deactivation. .

Select model

The selected model should be compatible with the selected triangular tape. Otherwise, the triangular tape will be abnormal in the pulley groove. When replacing the triangular tape, Zui will bring the old tape to the agricultural machinery department to buy, in case the model is wrong.
