The product nicely displays environmental protection and strength saving. Due to our vast item variety and wealthy ordeals in this business, makes certain the security and regularity of the important perform of elements.
Composition of pace escalating EPT
EPT parts of pace increasing EPT scenario(lower circumstance, middle scenario and protect), support base, massive EPT, EPT aXiHu (West Lake) Dis.s, EPTl wheel and lubrication program.
two,EPT qualities
Box is melt with thick metal with wonderful good quality to reach the intensity that the case necessary. Scenario need to take stress growing older remedy before the generate to reach the balance that needed. Substantial precision lathe machining is employed for the assembly of instances to insure the locating precision of every bearing holes and connected joint surface area.
Large EPTs and EPT shaft utilized carbon alloy metal forging blank, right after roughing, workpiece need to consider ultrasonic flaw detection method to quench. In buy to make sure the tooth surface with substantial hardness, tooth floor need to take carburizing and quenching treatment soon after semi-finishing .Good grind of tooth surface to insure the high precision, soon after finishing the generation of EPT, the balance test is necessary, the path velocity is 1500r/min and the harmony precision grade is G2.five. the path velocity of EPTl wheel is 3500r/min, the balance precision quality is G1, in so to guarantee the rotary precision of the EPTs.
EPT shaft use the alloy metal forging blank, EPT shaft requires quenched to make certain the intensity and durableness. After the semi- finishing, EPT need to grind to guarantee the accuracy of each and every workpiece.
When the assemble completed, the no-loading check must be keep two-4hours, the speed is 1100r/min, the temperature of shaft need to not exceed forty ordmC,the perform of EPT should be sleek, no hitting sound and concussion, each and every joint area ought to not have oil spill phenomenon.
