two,Specialized qualities
Box is melt with thick metal with wonderful quality to achieve the depth that the situation needed. Case ought to take tension ageing remedy ahead of the produce to attain the balance that essential.
Huge gears and gear shaft utilised carbon alloy steel forging blank, right after roughing, workpiece require to consider ultrasonic flaw detection procedure to quench. In order to make certain the tooth floor with high hardness, tooth area require to get carburizing and quenching treatment right after semi-ending .Fine grind of tooth surface area to insure the higher precision, right after ending the production of gear, the harmony check is needed, the expertise velocity is 1500r/min and the balance stage is G2.5.
Transmission shaft use the alloy metal forging blank, transmission shaft takes quenched to make positive the intensity and durableness. Soon after the semi- ending, transmission need to have to grind to assure the accuracy of each and every workpiece.
When the assemble finished, the no-loading test must be hold 2-4hours, the pace is 1200r/min, the temperature of shaft should not exceed 60ºC,the perform of equipment need to be sleek, no hitting sounds and concussion, every joint surface ought to not have oil spill phenomenon. 

Planetary gearboxes are employed in various instances where high efficiency and substantial reduction ratio are essential in a modest area. That includes high precision and high torque-to-volume ratio, it is ideal for torque increase, deceleration, precise positioning and manage of regenerative machinery. To ensure that the selected planetary gearbox is the very best fit for your software, it is important to think about parameters this kind of as torque, backlash and equipment ratios when picking a planetary gearbox.
