Model NO. SIGB001 Coating According to Customer Machining Tolerance +/-0.01mm Standard GB Certification ISO 9001:2008 Trademark Hangji Transport Package Sea Port Packing Specification for different requirements Origin Shaanxi, China HS Code 8455213000

Product Description

Composition of speed increasing gearboxSpare parts of speed increasing gearbox case, support base, big gear, transmission axis, bevel wheel and lubrication system.Technical characteristics1, technical parameterHighest speed output ratio45/157=0.2866Lowest speed output ratio60/157)x(55/60)=0.3503Motor power4500kWMotor speed1000/1300r/minHigh-speed output shaft speed4019r/minLow-speed output ratio3288r/minGear meshed speed77.2m/sThe backlash is less than0.36mm2, Technical characteristicsBox is melt with thick steel with great quality to reach the intensity that the case required. Case should take stress aging treatment before the produce to reach the stability that required.Big gears and gear shaft used carbon alloy steel forging blank, after roughing, workpiece need to take ultrasonic flaw detection process to quench. In order to ensure the tooth surface with high hardness, tooth surface need to take carburizing and quenching treatment after semi-finishing. Fine grind of tooth surface to insure the high accuracy, after finishing the production of gear, the balance test is needed, the experience speed is 1500r/min and the balance level is G2.5.Transmission shaft use the alloy steel forging blank, transmission shaft takes quenched to make sure the intensity and durableness. After the semi- finishing, transmission need to grind to guarantee the accuracy of every workpiece.When the assemble finished, the no-loading test should be keep 2-4hours, the speed is 1200r/min, the temperature of shaft should not exceed 60º C, the work of gear should be smooth, no hitting noise and concussion, every joint surface should not have oil spill phenomenon.
