Abstract
The utility model discloses a novel electric actuator. The electric actuator comprises a motor, a reduction gearbox, a drive gear, an intermediate gear, a worm, a worm gear, a gear shaft, a main gear, an output shaft and a box body, wherein the motor can rotate positively and negatively; the reduction gearbox is connected with the motor; the drive gear is arranged on an output shaft of the reduction gearbox; the intermediate gear is engaged with the drive gear and is arranged on the worm; the worm gear is engaged with the worm; the gear shaft is inlaid in the worm gear; the main gear is engaged with the gear shaft; an output shaft is embedded into the main gear; and the worm is arranged between the main gear and the drive gear. The novel electric actuator has the advantages that when running speed of the output shaft is required to be increased, the reduction gearbox with low transmission ratio is adopted; and the novel electric actuator is high in transmission efficiency and has long service life, and the running speed of the output shaft can be adjusted.
Description
Technical field
The utility model relates to YE, particularly the rotary type YE.
Background technique
The prior electric final controlling element, it exists shortcoming following: 1, worm gear is installed in the output shaft of YE, so the suffered pressure of the flank of tooth is big, and the easy abrasion life-span is short.Strengthen worm gear and worm screw size in order to reduce pressure; 2, the worm gear at 90 degree rotary type YEs only uses 1/4th the number of teeth, all the other numbers of teeth of 3/4ths do not use all the time and when wasting material the YE volume big; 3, be pressed into motor in the YE casing easy to replace motor not at the use scene; 4, can not change the velocity ratio of YE, therefore can not directly change the switching speed of valve; 5, an employing number is 1 worm screw, and helix angle is little, therefore causes the transmission efficiency of worm screw low; 6, working life is short.
The model utility content
The purpose of the utility model is to provide transmission efficiency high, and long service life can change the running speed of output shaft, and field maintenance is YE easily.Overcome the shortcoming and defect that exists in the existing YE.
To achieve these goals, the technological scheme taked of the utility model is:
The electric final controlling element, but comprise the motor of clockwise and anticlockwise, the speed reducer that is connected with motor; Be installed in the actuation gear of reduction gearbox output shaft, with the intermediate gear of actuation gear engagement, the worm screw that intermediate gear is installed; With the worm gear of worm meshing, be embedded in the gear shaft of worm gear, with the master gear of gear shaft engagement; Be embedded in the output shaft of master gear, casing, worm gear are arranged between master gear and the actuation gear.
But the motor of clockwise and anticlockwise can be changed the speed reducer of velocity ratio, is installed in the actuation gear of reduction gearbox output shaft; With the intermediate gear of actuation gear engagement, the piece-ups that link to each other with intermediate gear are 2 worm screw, with the worm gear of worm meshing; Be embedded in the gear shaft of worm gear; With the master gear of gear shaft engagement, be embedded in the output shaft of master gear, casing.Can change the speed reducer of different drive ratios as required, change the running speed of output shaft.Therefore worm gear is installed in gear shaft, and gear shaft and gear reduce the flank of tooth pressure of worm gear, and life-saving reduces wear.An employing number is 2 worm gear increase helix angle, improves transmission efficiency, and long service life reduces wear.The velocity ratio of gear shaft and master gear is between 1: 3 to 1: 4.Can manpower rotary worm axle when having a power failure, close or machines such as valve that unlatching is connected with output shaft.
Working principle: work as motor rotation, actuation gear, intermediate gear, worm screw, worm gear, gear shaft, master gear, output shaft rotate.Output shaft drives runnings such as valve, air door.
The beneficial effect of the utility model:, change the less speed reducer of velocity ratio when needs improve the output shaft running speed.This product transmission efficiency is high, long service life, can change the running speed of output shaft.
