Abstract
A speed reducer used in a server is disclosed to include a first planetary gear set, a planet gear carrier, an internal gear surrounding the first planetary gear set, and an output gear. The first planet gear includes a first sun gear mounted on the motor output shaft, at least one first planet gear pivotally coupled at the first planet gear carrier and meshed with the first sun gear and the internal gear for driving the first planet gear carrier and the output gear to rotate. Thus, the first planetary gear set reduces the revolving speed of the rotary driving force outputted by the motor output shaft, and effectively transfer the rotary driving force to the output gear, achieving the advantages of low backlash and long service life, reducing power transfer loss, increasing server output torque, and providing high speed ratio, high design flexibility and high assembly yields.
