The invention belongs to the technical field of driving mechanisms of electric actuators and particularly relates to a tooth wheel type position transmitting driving mechanism for an electric actuator. The tooth wheel type position transmitting driving mechanism comprises a box body; a worm shaft is arranged in the box body; a worm gear is fixedly arranged on the worm shaft; and a worm meshed with the worm gear is also arranged in the box body. The tooth wheel type position transmitting driving mechanism also comprises a position transmitting driving component for driving the worm; a mounting hole for mounting the position transmitting driving component is formed in the box body; the position transmitting driving component comprises a tooth wheel shaft; a tooth wheel is fixedly arranged at one end of the tooth wheel shaft; the tooth wheel is meshed with the worm; a positioning sleeve is arranged in the mounting hole; a first shaft collar is arranged on the positioning sleeve; a first sealing ring is arranged between the positioning sleeve and the mounting hole; the tooth wheel shaft is arranged in the positioning sleeve; a second shaft collar is arranged on the tooth wheel shaft; and a second sealing ring is arranged between the tooth wheel shaft and the positioning sleeve. According to the tooth wheel type position transmitting driving mechanism disclosed by the invention, errors caused by adopting helical gear and worm driving are effectively overcome.

Description

Drive mechanism is sent out in a kind of YE cutter position
Technical field
The invention belongs to YE drive mechanism technical field, particularly relate to a kind of YE cutter position and send out biography Motivation structure.
Background technology
YE is a kind of driving means being provided that straight line or rotary motion, and its basic actuator is for valve Driving to standard-sized sheet or fully closed position, the actuator for control valve can accurately make valve go to any position.Perform Being provided with working shaft on device, executor is through working shaft band ovable valve stem action, thus realize driving valve to standard-sized sheet or The position that person is fully closed.
In prior art, working shaft drives typically by helical gear or Bevel Gear Transmission, but uses helical gear or cone tooth Wheel, volume is relatively big, installation process is complicated, can produce axial thrust at the volley, produces axial arrangement and damages, causes biography Produce error during Dong, affect the service precision of executor.
Electronic hold accordingly, it would be desirable to a kind of simple in construction of R & D design, installation process are simple, stable drive, driving error are little Row device drive mechanism.
Summary of the invention
The present invention solves technical problem present in known technology and provide that a kind of novel structure is simple, installation process simple, Drive mechanism is sent out in the YE cutter position that stable drive, driving error are little.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: a kind of YE tooth Wheeled position is sent out drive mechanism and is included casing, is provided with worm-wheel shaft in casing, and worm-wheel shaft is fixedly installed worm gear, in casing also It is provided with the worm screw being meshed with worm gear;Also include, for driving the position of worm screw to send out transmission component, described casing offering use The installing hole of transmission component is sent out in installation position;Institute's rheme is sent out transmission component and is included roller axle, and one end of roller axle is fixedly installed Gear wheel, gear wheel is meshed with described worm screw;Described installing hole is provided with positioning sleeve, positioning sleeve is provided with the first axial trough, The first shaft retaining ring for limiting positioning sleeve axial location is installed in the first axial trough, between positioning sleeve and installing hole, is provided with One sealing ring;Described roller axle is arranged in described positioning sleeve, and roller axle is provided with the second axial trough, installs in the second axial trough There is the second shaft retaining ring for limiting roller axle axial location, the second sealing ring is installed between roller axle and positioning sleeve.
Advantages of the present invention and good effect be: drives worm screw to rotate, with tradition by installing gear wheel on executor's casing Helical gear compare, structure is simpler, simplifies installation process, and stable drive, will not produce axle in transmission process To thrust, extend whole position and send out the service life of transmission component, overcome and prior art uses tradition helical gear and worm screw Error during transmission.
Preferably: between described second shaft retaining ring and positioning sleeve, elastic washer is installed.
Preferably: described first sealing ring and the second sealing ring are O type rubber seal.
Accompanying drawing explanation
