Gearbox with breather system
Abstract:
A gearbox is provided having an integrated breather system. The output shaft of the gearbox has integrated therein a breather bore with a top port in the top end of the output shaft and a bottom end in the side of the output shaft. The top end is in communication with the atmosphere while the bottom end is in communication with the inner oil reservoir of the gearbox. By incorporating the breather directly into the output shaft, air locking is reduced or even prevented. Further, the distance between the maximum and minimum oil fill levels is increased thereby allowing for a reduction in accidental over or under filling of the gearbox. In addition, accidental spillage of oil into the environment is reduced as the top breather port exists on top of the gearbox and may optionally include a breather line extending further upward. The reduction in air locking allows for increased accuracy in oil filling as well as reduced maintenance on the gearbox.
