Oil and heat resistance properties of the belt oil and heat resistance belt (the belt is described as O & HR) is a conventional oil and heat on the belt of the application requirements, although the definition of RMA standard, but in fact this Description containing burnt unclear, oil and heat are actually two different requirements of the belt should be distinguished. Oil resistance: occasional splash of oil or grease on the belt of the belt normally do not normally have too much negative, however, oil belt as long as the oil or grease within a reasonable range of performance does not deteriorate quickly, a lot of oil or grease on any belt can cause the belt to slip heat, too much oil and petroleum products will cause a decline in invasive rubber adhesive force expansion and a rubber member, causing the belt to break. Heat resistance: any standards are not well defined temperature limits to ensure satisfactory performance, however, a suitable application belts are normally required to + 60 ℃ between the ambient temperature at -35 ℃ to. Materials and structures of the belt determines the heat of the relative scope and duration, the following table is expressed in good and very good. Ozone resistance ozone resistance properties of the belt characteristic is the ability of a chemical corrosion resistance in the ozone environment because ozone can cause chemical bonding and decomposition, failure mode is cracking, degradation of rubber depends on ozone concentration and exposure frequency, when the belt when squeezed, since ozone-induced degradation of the rubber will increase, in theory, a large cross-section of the belt on a pulley when the degradation suffered by the small cross-section to be more than a belt bends in the following table with good and well represented. Antistatic properties in a number of international standards (ISO, RMA), the conductivity and conductivity of the test belt has a specific description, in some dangerous environment, you need a certain degree of protection is recommended, such as the entire ground system to ensure against unexpected of electrostatic discharge, a conductive brush or similar device can also be static belt around released.

High ambient temperature will accelerate the aging of rubber, leading to premature failure of the belt, laboratory data (below) illustrates the relationship between ambient temperature and the V-belt life, the test results show that the ambient temperature increase in the ambient temperature 20 ℃ (temperature increase belt 10 ℃), V-belt life will be reduced by half, normal industrial belt drive typical temperature range should be between 15 ℃ to + 38 ℃, standard belt design is based on such a range.

One of the most common maintenance problems V belt slippage is a common source belt due to improper maintenance and relatively harsh operating conditions caused by the installation of the belt tension is too low, resulting in a round tank V belt slipping, Maintenance is relatively rare problems include dislocation pulley, the pulley wear, bearing wear, bright V belt on both sides may be pointed out these problems. If the environmental conditions and inadequate maintenance are excluded, then you need to check whether the harsh operating conditions, such as high-load motor in the original system design considerations will likely lead to running belt slipping. Reduce heat to high ambient temperature applications, through belt strap around the ventilation to reduce operating temperature can be added to cover the hole in the belt, the pulley reinforced or provide external cooling device to complete. If the belt slip is caused due to lack of drive system design, which you need to consider re-designed to increase the ability to drive the load, if the belt slippage occurs at the right drive system, the installation should consider increasing belt tension or replace worn pulleys. If the heat produced in the belt drive system itself, may need to be redesigned, and some belt-driven design tips to help reduce heat generation. ● use more belt to reduce the load ● use of large belt pulley diameter to reduce bending stress ● reduce the cross section of each belt type belt or toothed belt in order to increase the flexibility of V
