Speed growing EPT box of 135m finishing mill

Composition of speed rising EPT
EPT areas of pace growing EPT situation(reduced scenario, center situation and include), help base, large EPT, EPT aXiHu (West Lake) Dis.s, EPTl wheel and lubrication program.

EPT traits
Box is soften with thick steel with fantastic good quality to attain the depth that the case needed. Circumstance should just take stress aging therapy prior to the create to get to the balance that essential. Higher precision lathe machining is employed for the assembly of instances to insure the finding accuracy of every single bearing holes and relevant joint surface.

Large EPTs and EPT shaft employed carbon alloy metal forging blank, following roughing, workpiece need to have to get ultrasonic flaw detection method to quench. In orEPTto guarantee the tooth area with high hardness, tooth surface want to just take carburizing and quenching treatment soon after semi-finishing. Fantastic grind of tooth area to insure the higher accuracy, following ending the production of EPT, the balance test is necessary, the trail velocity is 1500r/min and the harmony precision grade is G2.5. The trail speed of EPTl wheel is 3500r/min, the balance precision grade is G1, in so to guarantee the rotary precision of the EPTs.

EPT shaft use the alloy steel forging blank, EPT shaft takes quenched to make certain the depth and durableness. After the semi- finishing, EPT require to grind to ensure the precision of each and every workpiece.
When the assemble completed, the no-loading examination must be maintain 2-4hours, the speed is 1100r/min, the temperature of shaft need to not exceed forty ordm C, the perform of EPT ought to be smooth, no hitting sounds and concussion, every single joint floor need to not have oil spill phenomenon.
