Title:
LINK OPERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/069533
Kind Code:
A1
Abstract:
In the present invention, a bearing is interposed in a revolute pair of a base end-side link hub (2) and a base end-side end part link member (5). An actuator is controlled with a control device, with a runtime control which executes a defined work operation, and a grease circulation control which, while the runtime control is suspended, circulates grease which is sealed in the bearing, being carried out. A maximum value θmax of a bend angle in the runtime control will not exceed a maximum movable bend angle θ'max which is the maximum mechanically possible bend angle, and a maximum value of a bend angle in the grease circulation control will be greater than the maximum value θmax of the bend angle in the runtime control as well as smaller than the maximum movable bend angle θ'max.
