A transmission device for lifting a sickbed is fixed on a head mounting or a bed end of the sickbed and contains: a gear seat, a cover, a power input assembly, and a power output assembly. The gear seat includes a first conduit, a second conduit, a first opening, and a receiving orifice. The cover is covered on the first opening of the gear seat. The power input assembly includes an input shaft and a first bevel gear. The power output assembly includes an output shaft, a second bevel gear, and a support element. The support element is rotatably connected with the output shaft. The support element has multiple reinforcement ribs surrounding around an outer wall of the support element and configured to abut against an abutting fence of the second conduit, and the second bevel gear meshes with the first bevel gear.

A phase adjustment system 100 for a geared compressor 1 includes a phase adjustment jig 50 that is to be detachably provided in the geared compressor 1. The geared compressor 1 includes a drive gear 4 fixed to a drive shaft and having a largest outer diameter among a plurality of gears; a driven gear having a smaller diameter than a diameter of the drive gear 4 and meshing with the drive gear 4; and a gear casing accommodating the drive gear 4 and the driven gear. The phase adjustment jig 50 includes a fifth jig gear 66 that meshes with the drive gear 4 in a state where a frame 51 is fixed to the gear casing; and a manually rotatable handle 70 that is configured to rotate the fifth jig gear 66.
