MANUFACTURING METHOD FOR DRIVING DEVICE

摘要

The present invention provides a method for manufacturing a driving device. The method includes a DRY leak test step of performing the leak test of the driving device when a lubricating unit is inserted into the assembled driving device, and a performance test step of performing the performance test of the diving device after the lubricating unit is inserted into the driving device. A leak test is performed before the performance evaluation of the driving device. Thereby, a change in the internal temperature of the driving device and an oil layer which can exist in the driving device are removed. Accurate evaluation is performed so that the reliability of leak evaluation can be improved.
