The utility model relates to the improvement of the speed reducer of a kind of energy motor switch ball valve, dish valve and stopcock.
Prior art is during to above-mentioned valve switch, the speed range that its valve rod requires is generally at 0.25～2 rev/min, in order to realize this speed range, Tianjin second universal machine works realizes with a worm gear, worm reduction gear and after a NN type epicyclic reduction gear unit installation is connected, after these two speed reducer were installed and connected, volume, weight were bigger, and it is with after the smaller diameter valve installation is connected, form top-heavy, very inharmonious.
The purpose of this utility model is the improvement that a kind of partially slewing valve Electric actuator will be provided, it is the speed reducer in a speed reducer with worm and gear speed-reduction apparatus and the design of NN type epicyclic reduction gear unit, it not only can realize the motor switch valve, the stroke of control valve switch, and this device volume is little, and is in light weight.
Invention is achieved in that at first passes to worm screw by an external gear wheel with rotating speed when electrical power starts, worm screw drives worm gear and rotates.Worm gear is contained on the eccentric shaft upper end axle journal in the NN type planetary gear reducing mechanism.When worm gear rotates,, drive the straight pin type driving pawl on the eccentric shaft, eccentric shaft is rotated by oneself the castellated driving pawl of rectangle on one's body.Eccentric shaft drives planetary pinion and rotates, and planetary pinion drives output inner gear and rotates, thereby rotating speed is exported by output inner gear, and the Stroke Control of this device switch is: when output inner gear rotated, straight pin drive transmission closure plate rotated synchronously on it.Groove and the projection of transmission closure plate by being connected with stroke shaft rotates stroke shaft, the cam that is fixed on the stroke shaft upper end forwarded to depress sensitive switch when giving fixed position, makes the motor outage.
Advantage of the present utility model and effect:
The utility model designs a worm gear reducer device and a NN type epicyclic reduction gear unit in a speed reducer dexterously, thereby makes the volume of whole device, and weight is dwindled greatly.Compare with the same specification device of present domestic production, volume-diminished 40～50%, weight saving 40～60%, bare bones reduces 50～70%.This device row process control is simple, highly sensitive, after complete machine and valve are installed and be connected, can realize the Stroke Control of motor switch valve and valve switch.
