Abstract
The utility model relates to a gearbox of a large-caliber hidden-rod sluice valve. The gearbox of the large-caliber hidden-rod sluice valve is characterized by comprising an annular gear box body (5) and a bevel gear box body (6), wherein the annular gear box body (5) is fixedly connected on the bevel gear box body (6); a bevel pinion (7) and a bevel gear (8) are arranged in the bevel gear box body (6); and a sun gear (13), a planet gear (14) and a planet carrier (15) are arranged in the annular gear box body (5). The gearbox is used on the large-caliber hidden-rod sluice valve. Due to the fact that the gearbox increases a transmission ratio, torque is increased, and stronger opening force and stronger closing force are generated. Therefore, a gate disc can still be opened when the large-caliber hidden-rod sluice valve is under high water pressure. Compared with the method that a worm wheel and a worm are used for transmission, the opening speed and the closing speed of the large-caliber hidden-rod sluice valve which is provided with the gearbox are higher.
