2,Specialized attributes
Box is soften with thick metal with great quality to attain the depth that the circumstance required. Situation need to just take stress ageing treatment ahead of the create to attain the steadiness that required.
Large gears and equipment shaft utilized carbon alloy metal forging blank, right after roughing, workpiece need to just take ultrasonic flaw detection process to quench. In get to make certain the tooth floor with substantial hardness, tooth surface area require to consider carburizing and quenching treatment soon after semi-ending .Wonderful grind of tooth floor to insure the higher accuracy, soon after finishing the generation of gear, the harmony take a look at is required, the experience pace is 1500r/min and the stability stage is G2.5.
Transmission shaft use the alloy metal forging blank, transmission shaft will take quenched to make sure the depth and durableness. Soon after the semi- finishing, transmission want to grind to ensure the accuracy of every single workpiece.
When the assemble concluded, the no-loading take a look at ought to be preserve 2-4hours, the speed is 1200r/min, the temperature of shaft ought to not exceed 60ºC,the operate of equipment must be smooth, no hitting noise and concussion, every single joint floor ought to not have oil spill phenomenon.
