Description

The gear box structure of electric actuator
Technical field
The utility model belongs to the technical field of electric actuator, and in particular, the utility model relates to a kind of gear box structure of electric actuator.
Background technique
Valve is widely used in every profession and trade, such as, in various industrial pipeline such as petrochemical industry etc. for providing pipeline to dam, the effect such as current limliting; And electric actuator is used for keying and the folding degree of regulating valve.In prior art, electric actuator gear transmission structure is heavier, and gear-box volume is large, Heavy Weight, and production and processing is installed also inconvenient.Although traditional gear box structure can play the effect realizing stable drive, but because traditional gear-box is heavy, bring much negative impact equally: such as Total Product weight and volume are larger, and in transmission process, drive noise is also very large, and installation more complicated, Installation and Debugging work is also more loaded down with trivial details.In a word, the gear box structure of traditional electric actuator had both added the cost of product, have impact on again the using effect of product, there is certain defect.
Model utility content
In order to solve the problems of the technologies described above, the purpose of this utility model is the gear box structure providing a kind of electric actuator.
The gear box structure of electric actuator described in the utility model, is characterized in that: comprise the upper cover plate and lower cover plate that are oppositely arranged, and described upper cover plate and lower cover plate form the double layer construction with inner space by 4 root posts be positioned at therebetween; Described upper cover plate has the first circular trough, clutch shaft bearing is arranged in described first circular trough, described clutch shaft bearing is provided with bearing compressing tablet; Described lower cover plate has the second circular trough, and described second circular trough has the second bearing; Manual gear axle is assemblied on the clutch shaft bearing of described upper cover plate and the second bearing of lower cover plate, and two ends of described manual gear axle extend to the outside of described upper cover plate and lower cover plate respectively; And described manual gear axle can move up and down along described clutch shaft bearing and the second bearing; In described inner space, accommodate one-level gear, secondary gear and manual gear, described one-level gear and manual gear engage with the rotating shaft of described secondary gear respectively; Described manual gear is arranged on described manual gear axle, and manual gear axle between described manual gear and described lower cover plate is also provided with spring.
Compared with prior art, the gear box structure of electric actuator described in the utility model has following beneficial effect:
(1) gear box structure of electric actuator described in the utility model is simple, the high conformity of part, and interchangeability is strong, and thus versatility is high; And it is smaller and more exquisite that gear also can do, be conducive to the noise reducing transmission.
(2) structure of the present utility model is simply exquisite, fairly simple in production assembly process, not only increases manufacturing efficiency, and it is low to manufacture assembly cost; Also be convenient to after-sales service simultaneously.
(3) gear box structure of the present utility model is except can realizing the function of transmission, and attached manual function, just seem when adjustment and installation at the scene especially convenient, with manual fast verification, correctness can be installed, in use also can realize the function of power-off debugging.
Accompanying drawing explanation
Fig. 1 is the gear box structure schematic diagram of electric actuator described in embodiment 1.
Embodiment
Below with reference to embodiment and accompanying drawing, the structure to the gear box structure of electric actuator is described in further detail, and to help, those skilled in the art conceives model utility of the present utility model, technological scheme has more complete, accurate and deep understanding.
Embodiment 1
As shown in Figure 1, the gear box structure of the electric actuator described in the present embodiment, comprises the upper cover plate 1 and lower cover plate 2 that are oppositely arranged, and described upper cover plate 1 and lower cover plate 2 form the double layer construction with inner space by 4 root posts be positioned at therebetween; Described upper cover plate 1 has the first circular trough, and clutch shaft bearing is arranged in described first circular trough, described clutch shaft bearing is provided with bearing compressing tablet 8; Described lower cover plate has the second circular trough, and described second circular trough has the second bearing; Manual gear axle is assemblied on the clutch shaft bearing of described upper cover plate and the second bearing of lower cover plate, and two ends of described manual gear axle 7 extend to the outside of described upper cover plate and lower cover plate respectively; And described manual gear axle can move up and down along described clutch shaft bearing and the second bearing; In described inner space, accommodate one-level gear 4, secondary gear 5 and manual gear 6, described one-level gear 4 and manual gear 5 engage with the rotating shaft of described secondary gear 6 respectively; Described manual gear 6 is arranged on described manual gear axle 7, and manual gear axle between described manual gear and described lower cover plate is also provided with spring 9.In use, be equipped with motor gear and motor (not shown) before one-level gear, and realize action by transmission.When needs manually-operable, such as, during power-off debugging, only need pressing manual gear axle downwards, make the rotating shaft of manual gear and secondary gear depart from engagement, so can depart from motor gear, greatly facilitate manually-operable; And after manually finishing using, described spring can allow manual gear automatically reset.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model by reference to the accompanying drawings; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technological scheme is carried out; or design of the present utility model and technological scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
