Abstract

The utility model relates to a driving device for a secondary transmission valve. The driving device comprises a worm wheel and a worm, wherein the worm wheel is in meshed connection with the worm; the valve wheel is connected with a valve; and the worm is connected with a star gear mechanism. The driving device has the beneficial effects that: the star gear mechanism is effectively applied to the valve driving device, so that the functions of increasing the speed ratio and enhancing the output torque are realized; and moreover, the driving device has the advantages of small size, compact structure, high transmission ratio, high efficiency and stable transmission.

Description

A kind of secondary drive valve drive unit
Technical field
The utility model relates to a kind of valve actuator, particularly relates to a kind of secondary drive valve drive unit of high pulling torque.
Background technique
In the existing technology; The single-stage driving valve actuator is 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 secondary drive valve drive unit 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 secondary drive valve drive unit comprises that worm gear is connected with worm meshing with worm screw, said worm gear, and said worm gear connects valve, it is characterized in that said worm screw is connected with spider gear mechanism.
Above-mentioned a kind of secondary drive valve drive unit is characterized in that: said spider gear mechanism is arranged at the end on the worm screw.
The beneficial effect that the utlity model has: effectively spider gear mechanism is applied to 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 secondary drive valve drive unit comprises 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; Worm screw 200 is connected with spider gear mechanism 300, and spider gear mechanism 300 drives worm screw 200 and rotates; Worm gear 100 connects valve, at first drives worm screw 200 through spider gear mechanism 300 in the time of work and rotates, and worm screw 200 drives worm gear 100 motions, the driving that finally realizes valve through worm gear 100.
Spider gear mechanism 300 is arranged at the end on the worm screw 200, and is 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.
