Abstract
The utility model pertains to an electrical executor, pertaining to a transmission rig, which consists of a case body, a motor, a motor gear, a clutch, a gear shaft, a worm, and a handwheel shaft. The two ends of the worm shaft are respectively provided with centricpetal bearings, and the worm is engaged with the worm wheel. The utility model is technically characterized in that: the outer end of the handwheel shaft is fixedly arranged together with the handwheel, and the inner end of the handwheel is connected with the input part of the planet decelerating organ, and the output part of the planet reducing organ is connected with the worm shaft. The electrical executer connects the handwheel and worm shaft through the planet reducing organ. When the handwheel is moved, for the decelerating function of the planet decelerating organ, the valve can be opened or closed by a small force, which leads the manual operation to be more flexible and labor saving, furthermore, the utility model has reasonable structure, simpleness and reliability and low price, which can be widely applied to such industries as power generating, mine, metallurgy, petrochemical etc.
Description
Technical field
The utility model belongs to driving mechanism, especially with the supporting a kind of electric actuator of valve.
Background technique
In automatic control system, often to use the supporting conduct of electric actuator and valve to cut valve soon and use, this electric actuator is widely used in the industries such as generating, mine, metallurgy, oil.General electric actuator has two kinds of working methods: a kind of is under the normal operation mode, adopts to automatically perform the switch valve function; Another kind is in some cases, and as when system's Installation and Debugging, power failure or automatical control system break down, electric actuator can not be carried out, and must adopt manual executive mode to carry out switch motion.The manual actuator of existing electric actuator is directly connected to handwheel on the output shaft by hand wheel shaft, when manual executable operations, thereby need the artificial handwheel that rotates to drive the switch motion that output shaft is carried out valve, but this mode need just can be finished the open and close action of valve with very big power.Therefore, there is the manual operation difficulty in the manual actuator in this electric actuator, sometimes even can't open or close valve, has a strong impact on normal work.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of electric actuator of a kind of reasonable in design, flexible operation labour-saving is provided.
The utility model solves its technical problem and takes following technological scheme to realize:
This electric actuator, connect and compose by casing, motor, motor gear, clutch, gear shaft, worm screw, hand wheel shaft, handwheel, the worm shaft two ends of this worm screw are respectively equipped with radial bearing, the worm and wheel engagement, it is characterized in that: the outer end and the handwheel of this hand wheel shaft are solidly installed, the inner of this hand wheel shaft is connected with the input part of planetary gear speed reducing mechanism, and the output of this planetary gear speed reducing mechanism is connected on the worm shaft.
And there is splined hole in the axle center of the input part of described planetary gear speed reducing mechanism, and the inner head of the hand wheel shaft of Pei Heing is a splined shaft with it.
And, two circle locating slots are arranged on the outer border of described hand wheel shaft, be provided with the retaining spring steel ball on the hand wheel shaft hole wall in the hand wheel shaft casing.
And, described planetary gear speed reducing mechanism by with the star-wheel seat that is packed in box inside, star-wheel seat in star-wheel and star-wheel washer connect and compose.
And the output of described planetary gear speed reducing mechanism is solidly installed by gear washer and worm shaft.
Advantage of the present utility model and good effect are:
1. this electric actuator couples together hand wheel shaft and worm shaft by planetary gear speed reducing mechanism, and when moving handwheel, because the decelerating effect of planetary gear speed reducing mechanism can use less power can open or throttle down, this manual operations is laborsaving more flexibly.
2. this electric actuator reasonable in design, simple and reliable, cheap can operate in the industries such as generating, mine, metallurgy, petrochemical industry widely.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
As shown in Figure 1,
This electric actuator outside is a casing 20 that has base 21, box house one side is provided with motor 1, motor gear 2 outer rings of this motor are connected with a clutch 3, this motor gear connects and composes successively with the gear shaft 5, worm screw 8, hand wheel shaft 19, the handwheel 18 that are with ball bearing 4 outward, worm shaft 9 two ends of this worm screw are respectively equipped with radial bearing 6, these worm and wheel 7 engagements; This handwheel is installed in and the corresponding casing opposite side of motor position, the inner of this handwheel and the outer end of hand wheel shaft are solidly installed, the inner of this hand wheel shaft is connected with the input part of planetary gear speed reducing mechanism, there is splined hole in the axle center of the input part of this planetary gear speed reducing mechanism, the inner head of the hand wheel shaft of Pei Heing is a splined shaft with it, the output of this planetary gear speed reducing mechanism is connected on the worm shaft by gear washer 13, this planetary gear speed reducing mechanism by with the star-wheel seat 10 that is packed in box inside, star-wheel 11 and star-wheel washer 12 in the star-wheel seat connect and compose, in addition, two circle locating slots 17 are arranged on the outer border of this hand wheel shaft, be provided with the retaining spring steel ball of forming by spring 15 and steel ball 16 on the hand wheel shaft hole wall in hand wheel shaft casing 14, locating slot on the hand wheel shaft and retaining spring steel ball are used for the positioning action of hand wheel shaft, and soon hand wheel shaft combines with planetary gear speed reducing mechanism or breaks away from.
Its working principle: when the electronic work of needs electric actuator, handwheel is outwards pulled out, locating slot spring steel ball phase embedding on the hand wheel shaft, simultaneously, the splined shaft of hand wheel shaft head from planetary gear speed reducing mechanism splined hole be separated from, make hand wheel shaft and planetary gear speed reducing mechanism be separated from, motor rotates the open and close operation that drives worm screw and worm gear motion control valve; When needs electric actuator manual work, handwheel inwardly advances, locating slot on the hand wheel shaft and spring steel ball embedding mutually, simultaneously, the splined shaft of hand wheel shaft head be inserted into planetary gear speed reducing mechanism splined hole in, make hand wheel shaft be meshed, simultaneously, clutch is upwards pulled out with planetary gear speed reducing mechanism, make motor gear and gear shaft be separated from, when moving handwheel, the open and close that drive worm screw and worm gear control valve through planetary gear speed reducing mechanism deceleration back are operated, and realize manual work.
