Embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings.In the embodiment of Fig. 1-shown in Figure 3, a kind of electric valve manual operating device comprises the electromagnetic braking motor 1-1 that is installed on motor cabinet 1 one ends, and circular arc worm speed reducer 1-2, plane table thermoconductivity meter 1-3 and clutch manual adjustment mechanism 1-4 are arranged; The support of the other end of motor cabinet 1 and circular arc worm speed reducer 1-2 is connected, and the other end of circular arc worm speed reducer 1-2 support and the end of plane table thermoconductivity meter 1-3 are connected, and the other end of plane table thermoconductivity meter 1-3 is connected with clutch manual adjustment mechanism 1-4.The electric valve manual operating device that provides by the utility model, electromagnetic braking motor 1-1 arrives plane table thermoconductivity meter 1-3 to power transmission by coupling and gear shaft, by again power transmission being arrived circular arc worm speed reducer 1-2 after the deceleration of NGW mechanism, through slowing down once more, by the output shaft that is connected to the circular arc worm gear power is exported, obtain low-speed big, again by sprocket wheel chain control gate valve.Thereby constitute by electromagnetic braking motor---the complete Transmitted chains of plane table thermoconductivity meter---circular arc worm speed reducer---gate valve.
At Fig. 2, among the embodiment shown in Figure 3, the output shaft of aforementioned electromagnetic braking motor 1-1 is connected with gear shaft 3 through coupling 2, gear shaft is through two bearings 4,9 skies are enclosed within on the hollow worm screw 6 of circular arc of aforementioned circular arc worm speed reducer 1-2, hollow worm screw of circular arc and circular arc worm gear 5 often mesh, gear on the gear shaft 3 (sun gear) meshes with three planetary pinions 11 of aforementioned plane table thermoconductivity meter 1-3, this planetary pinion 11 is enclosed within on the planet axis 10 by two bearing 12 skies, three planet axis 10 five equilibriums are installed in the planet carrier 8, the hollow worm screw 6 of planet carrier and circular arc is keyed to one, and planetary pinion 11 also is meshed with the internal gear 13 of plane table thermoconductivity meter 1-3 simultaneously; The friction disk 19 of clutch manual adjustment mechanism 1-4 is connected with plane table thermoconductivity meter flange plate 16 through bolt 18, clutch shaft 15 is fixed on the casing of plane table thermoconductivity meter 1-3 through two bearings 14, its rear portion is provided with tapering spring housing 20, the outer conical surface of this tapering spring housing contacts with the conical surface of friction disk 19, by the front end of friction disk 19, tapering spring housing 20 clutch shafts 15 and internal gear 13 keyed jointings of plane table thermoconductivity meter 1-3, the tail end of clutch shaft 15 has the nut 21 of adjustment; Be linked with output shaft 22 on the aforesaid circular arc worm gear 5, this output shaft through two bearing fixing in the support of circular arc worm speed reducer 1-2.The friction disk 19 of aforementioned clutch manual adjustment mechanism 1-4 is provided with artificial rotatable handle 17.
When motoring condition, internal gear is locked in the rated torque by the clutch manual adjustment mechanism.As shown in Figure 2, bolt 18 is screwed into the flange plate 16 of plane table thermoconductivity meter 1-3, thereby friction disk 19 and plane table thermoconductivity meter flange plate 16 are fused, by friction disk, tapering spring housing, clutch shaft 15 keyed jointings internal gear 13, have promptly realized fixing internal gear.So internal gear 13 can not rotate, this just constitutes typical NGW plane table thermoconductivity meter, and its velocity ratio i=7.76(is with internal gear number of teeth Z
b=115, sun gear number of teeth Z
a=17 are example calculating).If load has surpassed rated torque, then the internal gear band clutch shaft and the tapering spring housing skids, and internal gear rotates, and cuts off the power output of plane table thermoconductivity meter to the hollow worm screw of circular arc, thereby realizes overload protection.
Because planet carrier 8 is keyed to one with the hollow worm screw 6 of circular arc, so the planet carrier outputting power of plane table thermoconductivity meter is transferred on the hollow worm screw 6 of circular arc immediately, the hollow worm screw 6 of circular arc often meshes with circular arc worm gear 5 again, and power promptly is transferred on the worm gear 5.Worm gear 5 and output shaft 22 keyed jointings, output shaft 22 is installed in the circular arc worm speed reducer support with two bearings 23, has constituted the circular arc worm speed reducer, its velocity ratio i
Snail=35(is with single start worm Z
1=1, worm gear Z
