oil resistance Triangular Belts application characteristics, because it is triangular. Features:
- Simple structure, low manufacturing and installation accuracy requirements, convenient use and maintenance, suitable for occasions with large two-axis central bureau
- Smooth transmission, low noise, buffering and absorbing vibration
- When overloaded, the transmission belt will slip on the pulley, which can prevent damage to weak parts and play a safety protection role. Disadvantages:
The reference length of the V-belt. When the V-belt is bent around the pulley, the layer whose length and width remain unchanged is called the neutral layer. Under the specified tension, the circumference measured along the neutral layer of the triangle belt is called the reference length Ld, also called the nominal length. It is mainly used to calculate the geometric size of belt transmission and mark the triangle belt, and its length has been standardized.
Most of the cores of the ordinary V-belt with core are cord cores, and a small part of them are cord fabric cores. Since these two core structures are fiber twisted or woven, the inter-fiber shearing during the operation of the V-belt causes the core to gradually break and elongate. Therefore, ordinary V-belts produced with cord and cord cores can only be used in low-load transmission systems.
The oil and heat resistance characteristics of the V-belt (described as OHR on the belt) are the traditional application requirements for the oil and heat resistance of the belt. Although it is defined in the RMA standard, this description is ambiguous. , Oil resistance and heat resistance are actually two different requirements of the belt, and should be separated.
Oil resistance: occasional oil or grease splashing on the belt will not be too bad for ordinary belts. However, oil-resistant belts will not deteriorate quickly as long as the oil or grease is within a reasonable range. The oil or grease on any belt can cause the belt to slip and heat. Excessive oil contamination of petroleum products will cause the expansion of the rubber and the cohesive fall of the rubber components, which will cause the belt to break.
Heat resistance: There is no well-defined temperature limit range in any scale to ensure satisfactory performance. However, a suitable high temperature resistance Triangular Belts are usually said to have a temperature between -35°C and +60°C.
