The group has taken element in the creating and revising of ISO/TC100 intercontinental chain standard numerous a long time in achievement and hosted the sixteenth ISO/TC100 Intercontinental once-a-year assembly in 2004. we have attained the trust of purchasers throughout the world. The solution well shows environmental protection and vitality preserving. Composition of EPTTl EPTT

EPTTl EPTT comma vertical aXiHu (West Lake) Dis.s comma EPTTl EPTT shaft comma paired EPTTl EPTT models and countershaft and EPTTl wheel models period of time

EPTT Functions colon

1 comma Cylindrical helical EPTTs and spiral EPTTl EPTT are produced of low carbon steel comma refined texture enhances the resilience of the EPTT blank period of time In orEPTTto boost the abrasive resistance of the EPTT comma tooth surface undertake the carburizing and quenching strategies to attain higher hardness comma
2 comma Medium carbon steel made vertical aXiHu (West Lake) Dis.s comma EPTT shaft and countershaft are processed by annealing comma normalizing comma hardening and tempering to boost the tenacity and depth of the workpiece comma all workpieces are grinded to advertise the precision period The assembled shaft and EPTT have the balXiHu (West Lake) Dis.Hu (West Lake) Dis.ng examination comma the speed is 4550 r sol min comma the balXiHu (West Lake) Dis.Hu (West Lake) Dis.ng precision grade is G1 interval
3 comma Box is mould by ductile iron and use the getting older warmth remedy to insure the stability period The bearing place among box and its protect is the important to ensure the whole accuracy period
4 comma The other parts of cone box are mold by carbon metal interval Thermal refining approach make sure the intensity of EPTTl EPTT interval When the make finished comma Corrosion treatment method is essential to increase the life span of workpiece period
