The worm 1 is used as a main transmission part and is connected with the connecting shaft 2 through a pin, and the hand wheel 3 is connected with the worm 1 through the connecting shaft 2. The connecting shaft 2 is a main transmission and power input part and drives the worm 1 to rotate through the pin. The connecting shaft 2 is driven to rotate by the hand wheel 3, and the connecting shaft 2 drives the worm 1 to rotate.
The fixed shaft 4 is arranged below the connecting shaft 2, and the fixed shaft 4 and the connecting shaft 2 are arranged in a cross shape. The worm wheel 5 is sleeved on the fixed shaft 4, and the worm wheel 5 is rotatably connected with the fixed shaft 4. The vertical section of the worm wheel 5 is semicircular, namely the worm wheel 5 is arranged in a 180-degree sector.
The worm 1 is provided with a gear, the worm wheel 5 is meshed with the worm 1, and the valve is connected with the worm wheel 5. The worm wheel 5 is a main transmission part, and the worm wheel 5 is connected with the driven valve and transmits the torque generated by the operation of the driving device to the valve shaft of the valve. The worm 1 rotates along with the rotation of the connecting shaft 2, the worm 1 drives the worm wheel 5 to rotate through the meshing with the worm wheel 5, and the worm wheel 5 drives the valve in meshing connection.
The drive further comprises an adjustment mechanism 6, the adjustment mechanism 6 being adapted to adjust and limit the rotation angle of the worm wheel 5, typically within a range of ± 5 °. The adjusting mechanism 6 comprises a jackscrew 61, a nut 62 and a positioning plate 63, the jackscrew 61 is symmetrically arranged at two sides of the worm wheel 5, and the nut 62 is sleeved on the jackscrew 61. Locating plate 63 is connected on worm wheel 5, jackscrew 61 is contradicted with locating plate 63 and is connected, and jackscrew 61 is contradicted with locating plate 63 and is connected. The top thread 61 is mainly used for limiting the rotation angle of the worm wheel 5, and the positioning plate 63 limits the maximum rotation angle of the worm wheel 5 to 180 degrees. When the worm wheel 5 is rotated to a desired angle, the worm wheel 5 is fixed by tightening the nut 62 and locking the jack 61.
When adjusting jackscrew 61, need rotate hand wheel 3 and drive worm 1 and drive worm wheel 5 rotatory, observe the indicator 7 of worm wheel 5 end installation this moment, when indicator OPEN or CLOSE of the pointing arrow alignment casing 8 of indicator 7, it can to lock jackscrew 61 with nut 62.
The driving device also comprises an indicating disc 7, the indicating disc 7 is connected to the end part of the worm wheel 5, and the indicating disc 7 rotates synchronously with the worm wheel 5.
