The material of rubber v belt,difference between the rubber v belt and the tooth v belt

Rubber v belt is a belt used in automobiles or agricultural machinery. Without the belt acting on the pulley, it is difficult for the machinery to operate. When selecting the belt, people are willing to choose long-life, wear-resistant, high-temperature and low-temperature resistant, so these characteristics are generally related to the material of rubber v belt. What is the material of rubber v belt?What are the differences from the v belt?

Rubber v belt material

Before, the rubber v belt was made of natural rubber, but the rubber v belt made of natural rubber has poor oil resistance, ozone aging resistance and heat and oxygen aging resistance. Natural rubber is easily soluble in gasoline and benzene, and its chemical properties are relatively active, so the natural rubber belt is easy to break or stick.

Later, the rubber belt was changed to neoprene, which has good physical and mechanical properties, oil resistance, heat resistance, ozone resistance, high tensile strength, elongation, aging resistance, but poor low temperature resistance.

Heiyi is the first batch of EPDM rubber V-belts applied to agricultural machinery. The rubber v belt made of this material can withstand low temperature of - 40 ℃, high temperature of 120 ℃, natural aging, excellent ozone resistance, low elongation, and excellent flexibility and cracking performance.

At present, most manufacturers producing rubber v belts are made of neoprene, and Heiyi is the first one to produce rubber v belts using EPDM.

Difference between rubber v belt and teeth v belt

Ordinary v belt is a common type of v belt, which is mainly used for various power transmission in industry and agriculture. The wedge angle is 40, and the relative height is about 0.7. It is composed of the covering layer, the stretching rubber layer, the strength layer, the buffer layer and the compression layer. The strength layer is composed of multi-layer cord or single row of cord, and the ratio of belt top width to belt height is 1.6.

The teeth v belt has two types of special belt core structure and rope core structure, which are respectively composed of cloth covering, top rubber, tensile body and bottom rubber. It is mainly applicable to the occasions with high speed.

The ordinary rubber triangle belt is generally composed of a cloth covering layer, an extension layer, a strength layer and a compression layer. The selected model should be compatible with the selected v belt, otherwise the teeth v belt will appear abnormal in the pulley groove. Therefore, if you want to replace the teeth v belt, you must take the old belt with you to buy it, so as not to mistake the model.

The above is a detailed explanation of the rubber v belt material and the difference between the rubber v belt and the teeth v belt, hoping to help you have a new understanding of the rubber v belt.
