1. Belt Category
1, toothed belt
Belts known as belt, toothed belt divided into single and double sided toothed belt types. The former is mainly used for single-axis drive, and the latter is a highly efficient multi-axis belt drive or reverse, since 1980 the Department of the emerging world. The toothed belt is divided into a trapezoidal shape of the teeth and the two kinds of arc-shaped, arcuate belt tooth to withstand the maximum torque. From the materials used, toothed belt can be divided into rubber and urethane type two categories, the former have ordinary rubber (typically neoprene) and a special rubber (mostly saturated nitrile rubber) points. Their structure is composed of steel cords or glass fibers and the outer layer of the strength of the rubber and the rubber layer is formed of nylon or polyurethane adhesive layer configuration.
2, flat band
is flat with a belt oldest species, it is simple in structure, easy drive, regardless of distance, and so replacement is easy to adjust, in a variety of industrial and agricultural machine has been widely used.
3, circular band
with a circular cross section is a circular belt, a drive which can be freely bent. This polyurethane made with multiple, usually without the core, the most simple structure, easy to use. Round with a tape drive to open up new avenues, the world needs a sharp increase in the amount of small machine tools, sewing machines, precision machinery, the future potential is great.
4, V-belt, it is divided into narrow and wide V-belt, small-angle and high-angle belt, punched belt active and, additionally, for cars, tractors and other engine driven fan with the belt, called the fan belt.
Common aspects of
with a fan in the generator, the compressor, the pump power and the like. Due to its fan with ordinary V performance requirements completely different individual statistics of industrially. It belongs to a higher contact temperature A V-belt for use in harsh environmental conditions, which is characterized mainly is used singly, the pulley is small, transmission distance is very short, the changing speed and power.
