Gear motor for miniature high-voltage switch

Abstract

The invention relates to a high-voltage switch component, and more particularly to a miniaturized gear motor for a high-voltage switch. The gear motor comprises a motor body and a reduction box; and output shafts are arranged at the motor body and the reduction box. The gear motor is characterized in that a worn rod is fixed at the output shaft of the motor body concentrically. A worm gear is arranged in the reduction box and includes a worm wheel section and a gear wheel section that are connected concentrically into one; and the worm rod of the output shaft of the motor body extends into thereduction box and cooperates with the worm wheel section of the worm gear. A shaft gear sleeves the output shaft of the reduction box; and the gear wheel section of the worm gear and the shaft gear are linked and cooperate with each other by a gear wheel transmission mechanism. The vertical space occupied by the gear motor is reduced and miniaturization development of the high-voltage switch is promoted.

Description

technical field [0001] The invention relates to a high-voltage switch component, in particular to a deceleration motor which can be used for a miniaturized high-voltage switch. Background technique [0002] A high-voltage switch is an electrical appliance with a rated voltage of 3kV and above that is mainly used to break and close conductive circuits. Breaking and closing are the two basic operations of the high-voltage switch, and both operations need to be realized by the operation of the deceleration motor. [0003] Traditional geared motors for high-voltage switches include a motor and a gear box, both of which have output shafts and are arranged in parallel; the output shaft of the motor extends into the gear box, and the output shaft of the motor and the gear box When the output shafts of the gears are used in linkage through multiple reduction gears, the output shaft of the reduction box in the reduction motor is connected with the opening and closing of the high-vol...

AI Technical Summary

Problems solved by technology

However, the torque transmission of the gear structure can only be parallel transmission, which limits the assembly of the output shaft of the motor and the output shaft of the gearbox in parallel, and the motor must be installed vertically on the gearbox

Installing this geared motor on the high-voltage switch occupies a large vertical space, which is not conducive to the miniaturization of the high-voltage switch
