The impact of temperature on the GATESBelt
Belt drive is defined as the temperature surrounding air temperature, operating temperature is defined as the Belt in the use of the actual temperature, Belt of the operating temperature is always to exceed the ambient temperature.
High ambient temperature will accelerate the aging of rubber, leading to premature failure Belt, laboratory data (below) illustrates the temperature and the V relationship with life, the test results showed that each increase in ambient temperature ambient temperature 208C (Belt temperature increases 108C ), V belt life will be cut in half, the normal driver of a typical industrial temperature range of Belt should be between 158C to +388 C, the standard Belt design is also based on such a range.
The following table is the Gates industrial V-Belt ambient temperature range of applications ：

High ambient temperature is the most common V-belt driven heat source, such as some Belt drive engines, drive near the burning pit, no ventilation hood near the driver so the driver need to consider when designing heat conditions. Belt due to improper maintenance and relatively harsh operating conditions caused by the heat source is a common skid is one of the most common maintenance problems with one of V Belt installation tension is too low, which leads to V with a slot in the wheel slip, Rare dislocation of maintenance issues including pulleys, pulley wear, bearing wear, V belt on both sides of the light may be pointed out these problems. If the environmental conditions and improper maintenance are excluded, then, need to check whether the harsh operating conditions, such as in the original system design to take into account the high-load operation of the motor may cause the skid Belt.
For high temperature applications is available through the Belt Belt around the ventilation to reduce the operating temperature, you can add in the Belt of the cover holes in the reinforced pulleys or provide external cooling device to complete. If the Belt of the slip is due to the lack of drive system, this time need to consider re-design to increase the ability to drive the load, the slip occurs if the Belt drive system in the appropriate circumstances, the installation should consider increasing the tension or Belt Replace worn pulleys.
If the heat generated in the Belt drive system itself, may need to re-design, and some tips on Belt-driven design helps reduce heat generation.
● Belt use more to reduce the load on each Belt
● The use of large diameter pulley to reduce the bending stress Belt
● Belt cross section to reduce the use of tooth model or to increase the flexibility with V
