Abstract
The utility model provides a manual device for an electric actuator; the manual device comprises a hand wheel, a small gear, a large gear and an output shaft, wherein the small gear and the large gear are bevel gears; the small gear is fixedly connected with a hand wheel bar of the hand wheel through a bearing; and one end of the output shaft is connected with the larger gear engaged with the small gear. The manual device provided by the utility model has the beneficial effects of having the function of converting the small torque into the large torque and reducing the three-quarter force and has the advantages of simple structure, convenience to maintain, low machining cost, high production efficiency and the like.
Description
Technical field
The utility model belongs to the armstrong's patent equipment technical field, especially relates to the manual operating device that a kind of electric actuator is used.
Background technique
Electric valve need be used manually-operable under special circumstances in existing technology, and the valve rod of existing manual operating device is connected with handwheel through a connection set, and hand directly drives handwheel, the big moment of transmission.Technical problems such as existing manual operating device exists wastes time and energy, inconvenient operation.
Summary of the invention
The problem that the utility model will solve provides a kind of manual power transfer mechanism, especially is fit to the manual operating device of valve control.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: the manual operating device that a kind of electric actuator is used is characterized in that: comprise handwheel, small gear, gearwheel and output shaft,
Said small gear and gearwheel are umbrella gear;
Said small gear is fixedly connected with the hand wheel pole of handwheel through bearing;
One end of said output shaft be connected with the gearwheel of pinion.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, reach the function that little torque axis turns to high pulling torque, reduced by 3/4 power; Have simple in structurely, easy to maintenance, processing cost is low, the manufacturing efficiency advantages of higher.
Description of drawings
Fig. 1 is the schematic representation of the manual operating device used of the electric actuator of the utility model
Among the figure:
1, handwheel 2, small gear 3, gearwheel
4, output shaft
Embodiment
As shown in Figure 1, the utility model reduces manual strength with large and small umbrella gear engagement driving.
The structure of present embodiment: the manual operating device that a kind of electric actuator is used, comprise handwheel 1, small gear 2, gearwheel 3 and output shaft 4, said small gear 2 is a umbrella gear with gearwheel 3; Said small gear 2 is fixedly connected with the hand wheel pole of handwheel 1 through bearing; One end of said output shaft 4 is connected with gearwheel 3 with small gear 2 engagement.
The working procedure of present embodiment: this mechanism is the power input mechanism under the electric actuator manual case.Handwheel 1 rotates and directly drives small gear 2 rotations, then through the engagement between the big bevel pinion, drives the rotation of large bevel gear 3, and gearwheel drives output shaft again and rotates.Thereby reach the function that little torque axis turns to high pulling torque, make the control of little moment of torsion change big moment mechanism into and become a reality.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
