Abstract
A gear train includes at least four gears sequentially engaged, multiple links configured to support the rotation shafts of the gears, and pins configured to fix the rotation shafts of the gears to the link, wherein the pins are installed such that, among the rotation shafts of the gears, two non-adjacent rotation shafts have both ends fixed to the link and one of adjacent rotation shafts has only one end fixed to the link.
Claims20
A linkage structure comprising:
- a gear train comprising at least four gears sequentially engaged;
- a plurality of links configured to support rotation shafts of each of the at least four gears;
- pins configured to fix the rotation shafts of each of the at least four gears to the link;
- wherein the pins are installed such that, among the rotation shafts of each of the at least four gears, two non-adjacent rotation shafts have both ends fixed to one of the plurality of links, and one of adjacent rotation shafts has only one end fixed to one of the plurality of links.

A universal driving device comprising:
- a ring gear;
- a sun gear configured to have a variable inter-axis distance with respect to a rotation shaft of the ring gear;
- a gear train configured to connect the sun gear and the ring gear;
- and
- a plurality of links configured to accommodate a change in an inter-axis distance between the sun gear and the ring gear, and connected to be rotatable with respect to each other to continuously maintain a power transmission state between the sun gear and the ring gear, the plurality of links supporting rotation shafts of gears constituting the gear train;
- wherein the rotation shafts of the gears constituting the gear train are formed by alternately arranging a rotation shaft among the rotation shafts of the gears having both ends fixed to one of the plurality of links and a rotation shaft among the rotation shafts of the gears having only one end fixed to one of the plurality of links along a power transmission path of the gear train.
