螺桿啟閉機的結(jié)構(gòu)特點：

1、手電兩用啟閉機采用螺桿螺旋傳動實現(xiàn)對閘門、堰門的啟閉。傳動螺桿均采用梯形螺紋并設(shè)有平面軸承，具有安裝維護簡單，操作輕巧靈活等特點。 

2、電動啟閉機采用正齒輪—蝸桿—蝸輪二級減速，滿足轉(zhuǎn)速慢，轉(zhuǎn)矩大的工作狀態(tài)。

3、行程控制機采用十進計數(shù)器原理，控制行程的誤差0.5%，轉(zhuǎn)矩保護控制是通過蝸桿產(chǎn)生軸向位移，來達到保護電器的原理。

4、根據(jù)環(huán)境的要求可分為普通型、戶外型、防爆型以滿足不同的要求。

5、開度指示采用齒輪傳動，精確可靠，并具有開閉信號燈光指示。

Structural features: 1. The flashlight dual-purpose hoist adopts screw drive to open and close the gate and weir gate. The transmission screw adopts trapezoidal thread and has plane bearing, which has the characteristics of simple installation and maintenance, light and flexible operation. 2. Electric hoist adopts two-stage deceleration of spur gear-worm-worm gear to meet the working condition of slow speed and large torque. 3. The principle of decimal counter is adopted in the stroke control machine. The error of the stroke is 0.5%. Torque protection control is based on the principle that the worm generates axial displacement to protect the electrical appliance. 4, according to the requirements of the environment, it can be divided into general, outdoor and explosion proof types to meet different requirements. 5, the opening indication adopts gear transmission, accurate and reliable, and has the indication of opening and closing signal and light.
