two, Technological qualities
Box is soften with thick metal with great good quality to attain the depth that the circumstance necessary. Situation should take pressure growing older remedy just before the produce to get to the balance that needed.
Big gears and gear shaft utilized carbon alloy metal forging blank, soon after roughing, workpiece want to take ultrasonic flaw detection procedure to quench. In get to make sure the tooth area with high hardness, tooth surface area want to just take carburizing and quenching treatment method right after semi-ending. Fantastic grind of tooth surface to insure the large precision, soon after ending the production of gear, the equilibrium test is essential, the experience pace is 1500r/min and the balance amount is G2.5.
Transmission shaft use the alloy metal forging blank, transmission shaft takes quenched to make confident the intensity and durableness. Following the semi- finishing, transmission want to grind to ensure the precision of every workpiece.
When the assemble completed, the no-loading examination ought to be preserve two-4hours, the pace is 1200r/min, the temperature of shaft should not exceed 60º C, the operate of gear ought to be smooth, no hitting noise and concussion, each and every joint floor need to not have oil spill phenomenon.
