Pace growing gear box of 90m ending mill
Composition of velocity escalating gearbox
Spare areas of speed increasing gearbox circumstance, help base, huge equipment, transmission axis, bevel wheel and lubrication technique.
Technical traits
one, technological parameter
| Optimum speed output ratio | 45/157=.2866 |

two,Technological traits
Box is soften with thick metal with excellent quality to achieve the depth that the scenario needed. Case must get anxiety growing older treatment method just before the create to achieve the balance that necessary.
Large gears and equipment shaft utilized carbon alloy steel forging blank, after roughing, workpiece require to get ultrasonic flaw detection approach to quench. In buy to make certain the tooth surface with substantial hardness, tooth area want to get carburizing and quenching therapy right after semi-finishing .Good grind of tooth surface to insure the substantial precision, right after finishing the generation of gear, the harmony examination is required, the experience velocity is 1500r/min and the balance degree is G2.5.
Transmission shaft use the alloy metal forging blank, transmission shaft takes quenched to make positive the depth and durableness. Soon after the semi- finishing, transmission need to grind to promise the accuracy of each workpiece.
When the assemble concluded, the no-loading test must be maintain two-4hours, the velocity is 1200r/min, the temperature of shaft need to not exceed 60ºC,the operate of equipment need to be clean, no hitting sounds and concussion, every joint area ought to not have oil spill phenomenon.
