Background technique
In present technology, single-stage driving valve manual driving device is owing to being subject to the restriction of speed ratio, specified input torque can not be amplified to required torque demand, can only rely on the method that strengthens input torque to increase output torque, the valve manual driving device torque power gain of single-stage driving is limited, development along with Chinese valve industry, large size valve, continuing to bring out of the valve of super sized type valve and hard sealing, particularly want now operation convenience abroad, after maximum input torque is limited, single-stage or twin-stage valve manual driving device, cannot carry out manually-operable to valve.
Summary of the invention
For above problem, the utility model provides three grades of manual driving devices of part of revolving valves of three grades of transmissions of a kind of employing.
The utility model solves the technological scheme that its technical problem adopts: three grades of manual driving devices of this part of revolving valves comprise one-level main shaft, one-level driving gear, secondary main shaft, secondary transmission gear, stationary housing, cover plate, described stationary housing is fixed on the main casing of drive unit, described cover plate is fixed on described stationary housing, and between stationary housing, forms assembly cavity; The worm screw of described drive unit inside gos deep into described stationary housing inside and is connected with described secondary transmission gear key; One end of described secondary main shaft is processed with the gear structure of one, with described secondary transmission gear engagement; Described secondary main shaft is rotatable to be assemblied between described stationary housing and cover plate, parallels with described worm screw, and the other end of described secondary main shaft fixes by bond structure and described one-level driving gear; One end of described one-level main shaft is processed with the gear structure of one, is meshed with the described one-level driving gear of stating, and the other end of described one-level main shaft is the input shaft that is processed with bond structure; The diameter of described one-level mainshaft gear end is less than the diameter of described one-level driving gear, and the diameter of described secondary mainshaft gear end is less than the diameter of described secondary transmission gear.
As preferably, the worm screw of described one-level main shaft and described drive unit inside is assemblied in coaxial position.
The beneficial effects of the utility model are: the drive part that turning valve three grades of manual driving devices in this part are rotary valve, be mainly used to realize the driving to the worm screw of drive unit inside and worm gear with handwheel assembling, further realize the torsion of spool is opened; This device is by described one-level main shaft input torque, by described one-level driving gear, be transferred on described secondary main shaft, then described secondary main shaft is transferred to warping force on described worm screw by described secondary transmission gear again, further described worm screw is transferred to warping force on described worm gear, three grades of transmissions have been realized, in transmission process, driving torque increases step by step, so just can, by the less torque of described one-level main shaft input, just can realize the larger moment of torsion of described worm gear output is opened rotary valve or closed.
Accompanying drawing explanation
Fig. 1 is the structural representation of three grades of manual driving devices of this part of revolving valves.
Embodiment
Below in conjunction with embodiment, the utility model is further illustrated:
As shown in embodiment in Fig. 1, three grades of manual driving devices of this part of revolving valves comprise one-level main shaft 1, one-level driving gear 2, secondary main shaft 3, secondary transmission gear 4, stationary housing 5, cover plate 6, described stationary housing 5 is fixed on back on the main casing 7 of drive unit, described cover plate 6 is fixed on described stationary housing 5, and forms assembly cavity between stationary housing 5; The worm screw 8 of described drive unit inside gos deep into described stationary housing 5 inside and is connected with described secondary transmission gear 4 keys; One end of described secondary main shaft 3 is processed with the gear structure of one, with described secondary transmission gear 4 engagements; Described secondary main shaft 3 is rotatable to be assemblied between described stationary housing 5 and cover plate 6, parallels with described worm screw 8, and the other end of described secondary main shaft 3 fixes by bond structure and described one-level driving gear 2; One end of described one-level main shaft 1 is processed with the gear structure of one, is meshed with the described one-level driving gear 2 of stating, and the other end of described one-level main shaft 1 is the input shaft that is processed with bond structure; The diameter of described one-level main shaft 1 gear end is less than the diameter of described one-level driving gear 2, and the diameter of described secondary main shaft 3 gear end is less than the diameter of described secondary transmission gear 4.
Rotary valve is mainly used to water or oils liquid to carry out Flow-rate adjustment, due in use, water or oil are normally under high pressure, spool reverses needs larger torque, at this moment usually adopt worm and wheel drive mechanism, in this drive unit, just use as shown in Figure 1 worm gear 9 and worm screw 8 structures, shown in be equipped with spool opening and closing device on worm gear 9, by torsion, complete.
The drive part that turning valve three grades of manual driving devices in this part are rotary valve, is mainly used to realize the driving to the worm screw 8 of rotary valve inside and worm gear 9 with handwheel assembling, further realizes the torsion of spool is opened, as shown in Figure 1, the axle head with keyway stretching out of described one-level main shaft 1 is used while being used for being connected with handwheel or other manual drives wheel, this device is by described one-level main shaft 1 input torque, by described one-level driving gear 2, be transferred on described secondary main shaft 3, then described secondary main shaft 3 is transferred to warping force on described worm screw 8 by described secondary transmission gear 4 again, described worm screw 8 is transferred to warping force described worm gear 9 again, three grades of transmissions have been realized, in transmission process, driving torque increases step by step, in the specific implementation, the diameter of described one-level driving gear 2 can be between 2~8 times of the diameter of described one-level main shaft 1 gear end, the diameter of described secondary transmission gear 4 can be between 2~8 times of the diameter of described secondary main shaft 3 gear end, the torque transmission applying like this will be extended on described worm screw 8 time between 4~64 times, described worm screw 8 is generally 8:1~80:1 with the velocity ratio of described worm gear 9, in the time of manually, the transmission efficiency of worm and gear is about 0.3, total warping force just can amplify 9.6~1536 times, so just can be by described one-level main shaft 1 be inputted to less torque, just can realize the larger moment of torsion of described worm gear output is opened rotary valve or closed.The concrete size as required moment of torsion of input and output decides.This compact structure, small volume, transmission effect is comparatively stable.In the process of transmission, progressively increase during torsion from described one-level main shaft 1 to described worm screw 8, described in like this when design, from one-level main shaft 1, secondary main shaft 3, to the shaft diameter of worm screw 8, can increase and decrease by ladder, simultaneously the corresponding facewidth of described one-level main shaft 1 and one-level driving gear 2, increases progressively with the corresponding facewidth of secondary transmission gear 4 to described main shaft secondary main shaft 3.Can under the mechanics that meets transmission requires, save as much as possible material like this, save machining period.
As shown in Figure 1, described one-level main shaft 1 is assemblied in coaxial position with the worm screw 8 of described rotary valve inside.So not only moulding is more attractive in appearance, and this coaxial design makes structure compacter, fixed component stressed more balanced.
