Abstract
The utility model relates to a driving device of a three-stage transmission valve. The driving device comprises a worm wheel and a worm, wherein the worm wheel is connected with the worm in a meshing mode; the worm wheel is connected with a transmission device of a valve; the worm is connected with a first-stage spider gear mechanism; and a second-stage spider gear mechanism is connected to the first-stage spider gear mechanism. The driving device of the three-stage transmission valve has the advantages that two stages of spider gear mechanism are applied to the valve driving device, so that the speed ratio is increased, and the function of output torque is improved; and the driving device is small in size, compact in structure, high in transmission ratio and efficiency, and stable in transmission.
Description
Technical field
The utility model relates to a kind of valve actuator, particularly relates to a kind of three grades of drive valve drive units of high pulling torque.
Background technique
In the existing technology; Along with the continuous development of heavy caliber, high pressure valve, original moment of torsion manually-operable drive unit can not satisfy the requirement of existing valve, so long as owing to receive the restriction of speed ratio; Can not specified input torque be amplified to required torque demand; Can only rely on the method that strengthens input torque to increase distortion, but the problem of machine take place to damage owing to input torque is excessive, the unusual inconvenience of operating and difficult through regular meeting.
The model utility content
The purpose of the utility model is in order to solve the existing defective of valve actuator in the existing technology, to provide a kind of three grades of drive valve drive units of high pulling torque to solve the problems referred to above.
To achieve these goals, the technological scheme of the utility model is following:
A kind of three grades of drive valve drive units; Comprise that worm gear is connected with worm meshing with worm screw, said worm gear; Said worm gear connects the transmission device of valve; It is characterized in that said worm screw is connected with first order spider gear mechanism, also be connected with second level spider gear mechanism in the said first order spider gear mechanism.
Above-mentioned a kind of three grades of drive valve drive units is characterized in that: said first order spider gear mechanism and second level spider gear mechanism are arranged at the end on the worm screw, and coaxial with worm screw.
The beneficial effect that the utlity model has: used two-stage spider gear mechanism at valve actuator, the function that realized increasing speed ratio, improves output torque, and the utility model volume is little, compact structure, velocity ratio is big, efficient is high, stable drive.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Embodiment
For making structure characteristic of the utility model and the effect of being reached there are further understanding and understanding, cooperate detailed explanation, explain as follows in order to preferred embodiment and accompanying drawing:
Referring to Fig. 1, a kind of three grades of drive valve drive units comprise that worm gear 100 and worm screw 200, worm gear 100 are connected with a joggle with worm screw 200, and worm screw 200 drives worm gear 100 rotations, and worm gear 100 connects the transmission device of valve; Worm screw 200 is connected with first order spider gear mechanism 300, and first order spider gear mechanism 300 drives worm screw 200 and rotates; 300 connection second level spider gear mechanisms 400 of first order spider gear mechanism; In the time of work; Driving first order spider gear mechanism 300 through second level spider gear mechanism 400 rotates; First order spider gear mechanism 300 drives worm screw 200 runnings, and worm screw 200 drives worm gear 100 runnings, the driving that finally realizes valve through worm gear 100.
First order spider gear mechanism 300 and second level spider gear mechanism 400 are arranged at the end on the worm screw 200, and be coaxial with worm screw 200.
In sum; Be merely the preferred embodiment of the utility model; Be not to be used for limiting the scope that the utility model is implemented; All equalizations of doing according to the described shape of the utility model claim scope, structure, characteristic and spirit change and modify, and all should be included in the claim scope of the utility model.
Claims (2)
