The Advantages of Polyurethane Timing belt

The Advantages  of  Polyurethane Timing belt:

　　1. No sliding when working, have accurate transmission ratio

　　Timing belt drive is a kind of mesh drive, although the Timing belt is an elastomer, but because the load bearing rope has the characteristic of not elongating under the action of tension, it can keep the belt pitch constant, so that the belt and wheel teeth groove can be correctly meshed, to achieve synchronous transmission without slippage, to obtain an accurate transmission ratio.

　　2. High transmission efficiency, good energy-saving effect

　　As the Timing belt for no sliding synchronous transmission, so there is a high transmission efficiency, generally up to 0. 98. It is compared with the v-belt transmission, there is an obvious energy-saving effect, available as the following examples to prove.

　　From the above examples, Timing belt drive in energy-saving potential, so the use of Timing belt drive can obtain high economic benefits.

　　3. Large range of transmission ratio, compact structure

　　Timing belt drive transmission ratio can generally reach about 10, and in the case of large ratio, its structure is more compact than the v-belt drive. Because the Timing belt drive is meshing transmission, its pulley diameter than relying on friction to transmit power v-belt pulley is much smaller, in addition, because the Timing belt does not require large tensioning force, so that the pulley shaft and bearing size can be reduced. Therefore, compared with v-belt transmission, under the same transmission ratio, Timing belt transmission has a more compact structure.

　　4. Easy maintenance, low running cost

　　Because the Timing belt in the bearing rope using very small elongation of glass fiber, steel wire and other materials made, so in the process of operation of the belt in the length is very small, do not need to be like v-belt, chain, etc. often adjust the tension. In addition, the Timing belt does not need any lubrication in operation, so maintenance is very convenient, and the operating cost is much lower than that of v-belt, chain and gear.

　　5. Can work normally under severe environmental conditions

　　In the harsh working conditions with dust and impurities, water and corrosive media, the chain is easy to rust, wear, v-belt will produce slippage, but the Timing belt drive can adapt to these conditions. Because it is meshing transmission, it will not slip in the case of rain, and water is a good lubricant for rubber, but can reduce the wear of the belt. When there is dust and impurities, because the Timing belt teeth into the pulley groove, the belt teeth will squeeze the original stay in the groove of the air, so that the air under pressure to both sides of the groove discharge, this air squeeze will play a role in cleaning the meshing surface, take away the role of dust and impurities, thus reducing the wear of the Timing belt.

In addition, Timing belt has high corrosion resistance, heat resistance, in the case of high temperature, corrosive gas can still work normally.
