Description

Technical fields:

[0001] This utility model belongs to the field of electric actuators, specifically to a manual operation device for rotary electric actuators. Background Technology

[0002] Existing spur gear electric actuators have their manual and output shafts on the same side, with the manual shaft located below the actuator. This results in very little manual operating space after the actuator is installed on the equipment, making operation inconvenient. Some electric actuators use a worm gear drive structure, with the worm serving as the manual shaft, located on the side of the actuator. This is convenient to use, but the worm gear drive structure suffers from relatively low efficiency. Utility Model Content:

[0003] The purpose of this utility model is to provide a manual operating device for a high-efficiency electric actuator, which has a simple structure, low cost, and convenient manual operation, overcoming the shortcomings and deficiencies of existing ordinary electric actuator mechanisms.

[0004] To achieve the above objectives, the present invention provides a manual operating device for an electric actuator, comprising an upper housing, a lower housing, an output shaft fixing plate mounted on the lower housing, a motor fixed on the output shaft fixing plate, a motor gear mounted on the motor shaft, the motor gear having a transmission spur gear and a manual large bevel gear, an intermediate gear meshing with the transmission spur gear, a gear shaft fixed on the intermediate gear, a main gear meshing with the gear shaft, an output shaft mounted on the main gear, a bearing cover mounted on the lower housing, and a manual shaft mounted on the bearing cover. The bearing cover has an oil seal hole, a bearing hole, and an O-ring groove. A manual shaft oil seal is installed in the oil seal hole, a manual shaft bearing is installed in the bearing hole, and an O-ring is installed in the O-ring groove. The manual shaft has a hexagonal hole and a manual small bevel gear, which meshes with the manual large bevel gear on the motor gear.

[0005] The following effects can be achieved according to this utility model:

[0006] When the electric actuator is powered on, the motor drives the motor gear, intermediate gear, gear shaft, main gear, and output shaft to rotate. For manual operation, insert a hex wrench into the hexagonal hole on the manual shaft and rotate the manual shaft, which in turn drives the motor gear, intermediate gear, gear shaft, main gear, and output shaft to rotate, thus achieving manual operation.

[0007] This invention, through a bevel gear structure manual shaft, avoids the limitations of the output shaft and installation equipment on manual operation, thus improving the convenience of operation. Attached Figure Description
