Description

Technical Field

[0001] The utility model belongs to the technical field of gear boxes, and in particular relates to a bidirectional output gear box. Background Art

[0002] Gearboxes are often used for power transmission or conversion in machines. They convert the power received on the driving shaft into the required power through gears, worm gears and other components and output it through the passive shaft to ensure stable operation of the machine. Bidirectional output gearboxes usually have two output shafts.

[0003] The existing bidirectional output gearbox has a complex internal structure, and the gearbox cover is not convenient to open for maintenance. Since the output shaft in the gearbox needs to transmit power through the meshing of two gears, after a period of use, if it is not cleaned in time, the friction between the two gears will easily generate iron filings. If the iron filings are not removed in time, the friction between the two gears will easily increase, resulting in a decrease in the efficiency of the power transmission of the two gears and a decrease in the transmission force of the output shaft.
