EPT parts of velocity rising EPT case, assistance foundation, huge EPT, EPT aXiHu (West Lake) Dis.s, EPTl wheel and lubrication technique.
1, technological parameter
Greatest velocity output ratio45/157=.2866
Lowest speed output ratio60/157)x(55/60)=.3503
Higher-velocity output shaft speed4019r/min
Reduced-velocity output ratio3288r/min
Equipment meshed speed77.2m/s
The backlash is significantly less than0.36mm
2, EPT qualities
Box is soften with thick metal with fantastic good quality to get to the depth that the case essential. Circumstance need to take tension ageing treatment just before the generate to get to the balance that essential.
Massive EPTs and EPT shaft utilised carbon alloy metal forging blank, right after roughing, workpiece require to take ultrasonic flaw detection approach to quench. In orEPTto ensure the tooth surface with high hardness, tooth surface area need to get carburizing and quenching treatment method soon after semi-finishing. Fantastic grind of tooth surface to insure the substantial precision, following ending the production of EPT, the equilibrium check is required, the encounter pace is 1500r/min and the stability stage is G2.5.
EPT shaft use the alloy metal forging blank, EPT shaft takes quenched to make positive the intensity and durableness. Following the semi- ending, EPT require to grind to promise the accuracy of every single workpiece.
When the assemble finished, the no-loading check need to be keep 2-4hours, the pace is 1200r/min, the temperature of shaft must not exceed sixty ordm C, the work of EPT need to be smooth, no hitting sound and concussion, each joint floor must not have oil spill phenomenon.
