A 3K type planetary gear speed reducer using standard module

摘要

PURPOSE: A 3K type planetary gear reduction device is provided to change a reduction gear ration by controlling the number of teeth of a gear and to enhance compatibility by using a standard unit system. CONSTITUTION: A sun gear(110) is connected to an input shaft. A first planetary gear(120) is interlocked with the sun gear. A first stage reduction unit is comprised of a first ring gear. The first ring gear is interlocked with the exterior of the first planetary gear. The second planetary gear is combined with the first planetary gear. A second stage reduction unit is comprised of a second ring gear(220). The second ring gear is interlocked with the exterior of the second planetary gear. The first stage reduction unit and the second stage reduction unit are divided into a first type and a second type according to output position.
