1. Composition of vertical transmission box
Transmission box, passive gear shaft, transmission gear shaft, spiral gear shaft set and transmission asix, oil box, bearing and support base of bearing.
2. Technical characteristics
Box is melt with thick steel with great quality to reach the high intensity & heavy load capacity that the case required. Case should take stress aging treatment before the produce to reach the stability that needed. In order to ensure the installation precise standard, box need to adopt total assemble produce.
Transmission gear shaft and passive gear shaft use carbon steel parts to forge, Tooth surface using the carburizing techniques to achieve high hardness, in order to make sure the loading and big twist distance requirement of gear. After finishing the installation, the balancing test is needed to take, the speed should be 600 r / min, the balance level is G6.3 to satisfy the demand precise of using.
Spiral bevel gear set, use carbon steel blank, spiral bevel surface experience the carburizing and quenching treatment to get the hardness that required, insure the heavy load possibility of gear shaft and big twist distance. Grinding the tooth surface and roll holes to reach the required high accuracy & durableness of spiral bevel gear set.
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 40º C, the work of gear should be smooth, no hitting noise and abnormal concussion, every joint surface should not have oil spill phenomenon. Vibration intensity should not exceed 4mm/s
