Precautions before installing the joint v belt

The joint v belt has two types of special belt core structure and rope core structure, which are respectively composed of four parts: wrapping fabric, top glue, tensile body, and bottom glue. The joint v belt with rope core structure is easy to manufacture, with ordinary tensile strength and low price. It is widely used in special belt core structures, with good toughness and strength, and is suitable for occasions with good rotational speed. The materials used and the quality of different V-belts are different, so the temperature and limit they can withstand are also different. Based on this, countermeasures and preparatory work can be taken in advance in the selection and actual testing to avoid unexpected accidents. When choosing the model of the joint v belt, we should adapt to the selected joint v belt, otherwise the v belt will have abnormal situations in the pulley groove. When replacing with a v belt, it is good to bring the old belt to the agricultural machinery department for purchase to prevent the model from being mistaken. In addition, the joint v belt should be stored separately. Strictly prevent contamination. During use, it is necessary to strictly prevent oil and mud stains on the v belt, avoid contact with corrosive substances such as acids and alkalis, and prevent early damage caused by slipping and corrosion of the v belt.

Before installing the joint v belt, if the center distance between the two axles is an adjustable layout, the center distance should be shortened first, and then the center distance should be adjusted according to the needs after the tape is installed; If the center distance between the two axles cannot be adjusted, a v belt can be first inserted into the wheel groove, and then the other pulley can be changed to install the v belt. Use the same method to install a set of v belts. Excessive looseness not only leads to simple slipping, but also adds wear and tear to the v belt, and even cannot transmit power; If it is too tight, it will not only stretch, deform and simply damage it, but also form the clutch bearing of the main bearing of the proposed machine, which will accelerate the wear of the V-belt due to excessive force. After the installation of the v belt, it is necessary to conduct an installation inspection. During the inspection, a straight pressure of about 2 kilograms should be applied by hand in the middle of each tape, and the sinking amount should be (20-30) millimeters. If it is not in order, it should be adjusted in a timely manner.

Working temperature and function of the joint v belt:

1. The skeleton is made of carbon fiber rope, which has a relatively low elongation rate and good flexibility; The proprietary tooth structure provides high shear force keyword ranking, low noise, and improves transmission power; Meanwhile, polyurethane has oil resistance.

2. Precision, strong synchronization, low noise, and good wear resistance characteristics.

3. When overloaded, the transmission belt will slip on the pulley, which can prevent damage to weak parts and play a stabilizing and precious role.

4. Polyurethane mixtures can resist wear and are not afraid of ozone and most environmental factors.

5. The extra 60 ° angle and the structure of polyurethane material enable it to withstand large loads when operating in small spaces compared to the conservative v belt.

6. Suitable for industries such as mechanical tools, medical equipment, inventory equipment, micro appliances, hair dryers, and woodworking machinery.

7. The meticulous manufacturing method enables it to operate peacefully.

8. The back groove design provides good stability and flexibility.

9. The working temperature is between -65 ℉ to+180 ℉ (-54 ℃ to+85 ℃).

10. Smooth transmission, low noise, buffering and vibration absorption effect, reducing costs.

11. The structure is simple, and the manufacturing and installation accuracy requirements are not high, so it is easy to use and maintain. The v belt is suitable for situations where the central area of the two shafts is large.

A joint v belt is a group of v belts formed by connecting the top surfaces of similar popular or narrow v belts. The connecting layer of the joint v belt can reduce the non equivalent vibration of a single v belt to a lower limit by mutual elimination, and endow each v belt with lateral rigidity and stability through joint assembly. During installation, it is prohibited to use tools to forcefully pry or pull on v belts, wide angle belts, PVC conveyor belts, and Gates transmission belts to prevent the v belts from extending or becoming too loose or tight. When installing belt pulleys in a series of grooves, the middle of the two upper pulleys needs to be aligned, otherwise it will cause the triangular tape to work unilaterally, wear and tear tight, and reduce the service life of the triangular tape. When a joint v belt needs to be replaced, a specified model of triangular tape should be selected, and the tightness of each group of triangular tape should be equal. It is not allowed to mix new and old v belts or reduce the number of pieces. Otherwise, the force on the new and old v belts will be uneven, and even the old v belts will not work, affecting power transmission and shortening the service life of the v belt.
