HEIYI founded in ***5,is the first China manufacturer of rubber transmission v belts that applies EPDM materials to toothed belts.Most of the material on the market is natural rubber and CR material.Curretly our factory had improved all of our series products into EPDM material in order to meet the market require!
First of all, what are the characteristics of EPDM in terms of materials? Here I summarize as follows: Better heat resistance.
After testing, the temperature range is **0ºC to **0ºC. Compare to the traditional CR rubber has a temperature resistance of **0°C.
At present, belt manufacturers in Germany, Japan, and the United States are all making EPDM materials as their latest technology.
In addition, in terms of appearance, what are the advantages compared with traditional wrapped belt? Below I list them one by one:
1.*5% capacity increase over wrapped belts
2.Superior flexibility.
3.No re-tensioning required.
4.Reduce wrapped belt drive width up to *0%.
5.Increase efficiency up to 3% over wrapped belts.
6.Use smaller diameter pulleys than wrapped belts.
7.Moulded notches reduce and evenly distribute
8.Thermal and bending stresses.
9.Reduce drive maintenance
Including cords, we are divided into polyester cords and aramid cords, which are suitable for different working parts.
At present, Heiyi is the company in the world range firstly put toothed belts, variable speed belts, and single belts, largely used in agricultural machinery and auto parts. Our partners include LOVOL, ZOOMLION, WORLD, YHMAC, China YTO. In our cooperation, there are many companies that use our toothed belts. Taking the toothed belt as a new selling point will greatly increase the sales of agricultural machinery products. And our price is competitive in the same industry.

Example Energy Savings Calculations
A continuously operating, ***-horsepower (hp), supply-air fan operates at an average
motor load of *5% while consuming **7,**0 kilowatt-hours (kWh) of electrical energy
annually. What are the annual energy and dollar savings if a *5% efficient (η1) V-belt is
replaced with a *8% efficient (η2) synchronous belt? Electricity is priced at $0.*8/kWh.
Energy Savings = Annual Energy Use x (1 - η1/η2 )
= **7,**0 kWh/year x (1 - *5/*8) = *6,**0 kWh/year
Annual Cost Savings = *6,**0 kWh x $0.*8/kWh = $1,**0
