V-belt drive work, the belt on the pulley on the corresponding slot, with the groove on both sides of the friction to achieve transmission. Automotive V Belts are usually used in several rows and have a corresponding number of slots on the pulley. With the V-belt drive, with a good contact with the wheel, sliding small, relatively stable transmission, smooth operation. The V-belt drive is suitable for applications where the center distance is shorter and the larger transmission ratio (7 or so) is better for both vertical and inclined transmissions. In addition, due to the number of V-belt and use, one of the damage will not happen accident.
Triangle tape is the most used in the V-belt, it is by the strong layer, extension layer, compression layer and cladding layer made of endless ring tape. The strong layer is mainly used to withstand tension, extension layer and compression layer in the bending from the role of stretching and compression, covering the role of the main layer is to enhance the strength. Triangle tape cross-sectional size and length of the standard specifications. In addition, there is a kind of active V-belt, its cross-sectional size standards and the same triangle, and the length of the specifications are not restricted, easy to install tight, local damage can be replaced locally, but the strength and stability are not as triangular tape. V-belt is often used in parallel, the design can be transmitted by the power and the speed of the ferry to determine the type of belt, root and belt size.
1) Standard V-belt
For household facilities, agricultural machinery, heavy machinery. The ratio of the top width to the height is 1.6: 1. The use of cords and fiber bundles as the pulling elements of the belt structure than the wide and narrow type of belt transmission power is much smaller. Because of their high tensile strength and lateral rigidity, this belt is suitable for the sudden changes in the load of poor working conditions. Belt speed allowed to reach 30m / s, bending frequency up to 40Hz.
2) Narrow V-belt
Used in the 1960s and 1970s for automotive and machine structures. The ratio of the top width to the height is 1.2: 1. Narrowed triangular belt V Belt Global Supply is a modified variant of the standard type V-belt, which eliminates the central part of the power transfer. It delivers more power than the standard width of the same type of triangle. A belted belt variant that seldom slips when used on a small pulley. Belt speed is allowed to reach 42 m / s, bending frequency up to 100Hz. _________________ Bernice Sparks
