DECELERATOR STRUCTURE USING PLURALITY OF TWO-SPEED SPUR GEARS, AND ACTUATOR MODULE INCLUDING SAME

摘要

The present invention relates to a decelerator structure using a plurality of two-speed spur gears, and an actuator module including the same. The decelerator structure using a plurality of two-speed spur gears that decelerates a high-speed rotation of a rotating motor into a low speed and transmits the torque to an output gear with an outer circumferential surface where a toothed surface is formed includes a primary deceleration unit that is composed of an upper spur gear and a lower spur gear which is integrally formed below the upper spur gear and has two-speed spur gears for primary deceleration which are coupled with the output gear to be rotated; and a secondary deceleration unit that is formed between the last two-speed spur gear of the primary deceleration unit and the output gear and has at least two two-speed spur gears for secondary deceleration which have an upper spur gear engaged with the lower spur gear of the last two-speed spur gear of the primary deceleration unit and a lower spur gear engaged and interlocked with the toothed surface of the output gear, wherein at least two two-speed spur gears for secondary deceleration are formed to be symmetrical to each other.
