Abstract
The utility model relates to a transmission device for an automatic voltage regulator, which is composed of a motor (12), a shaft connector (10), a shaft (9), a worm wheel (8), a worm screw (7), gear pairs (5, 6), a main shaft (4), a carbon brush frame (13), a carbon brush (14), a wire package (1) and a support frame (2) of a ring-shaped autotransformer. The utility model has the advantages of simple structure, stable transportation and transmission and low noise. Because the transmission of the worm wheel and the worm screw have self-locking character, the influence of inertia on the accuracy of the voltage regulation is overcome. The operational speed of the carbon brush can be properly raised, and the response time of the automatic voltage regulator is reduced to improve the performance of the automatic voltage regulator.
Description
The utility model relates to a kind of transmission device of automatic voltage regulator.
The transmission device of common automatic voltage regulator is made up of reduction box, gear, axle, annular autotransformer line bag, brush holder and carbon brush etc. that motor, multistage travelling gear are formed.The transmission device of the automatic voltage regulator that patent ZL93242783.9 discloses comes to this.Owing to the high rotating speed of motor will be become the slow-speed of revolution, could satisfy the requirement of the automatic Regulation work of automatic voltage regulator.Because gearratio is big, the gear drive level is many, has just caused drive gap big, bumpy motion, and noise is big, and inertia is big, has reduced the pressure regulation precision, shortcomings such as complex structure.
The purpose of this utility model is to provide a kind of fortune to pass steadily, and noise is low, and travelling gear is few, and is simple in structure, has to have overcome the transmission device of inertia to the automatic voltage regulator of the influence of pressure regulation precision.
The purpose of this utility model is achieved in that by motor (12), shaft joint (10) axle (9), worm gear (8), worm screw (7), gear pair (5,6), main shaft (4), brush holder (13), carbon brush (14), annular autotransformer line bag (1), support (2) is made up of motor (12) by shaft joint (10) transmission worm screw (7), by worm screw (7) transmission worm gear (8), the affixed axle of worm gear (8) and gear (6) (9), gear (5) and gear (6) engagement, gear (5) and the affixed main shaft of brush holder (13) (4), make the carbon brush (14) that is located at brush holder (13) end change contact position with annular autotransformer line bag (1), reached the purpose of adjusting voltage
The utility model has only used one group of worm gear, worm screw and gear seldom promptly to reach the purpose of deceleration transmission, so simple in structure; Because travelling gear is few, so fortune passes steadily, noise is low; After motor outage, the inertia of the brush holder of transmission device (13), gear pair (5,6) and worm gear (8) can the transmission worm screw, this be because of, the self-locking action of worm screw, worm-drive, overcome the influence of inertia to the pressure regulation precision, thereby, the accuracy of pressure regulation improved.
