ける作業腕の駆動装置。[Scope of Claim for Utility Model Registration] (1) In a work machine arm in which arm members are jointed so as to be relatively rotatable and a work tool is attached to the arm,
The distal end of one driving side arm member is formed into a yoke shape, a hollow shaft member is attached to each of the shaft holes bored in the left and right yoke parts, and the proximal end of the other driven side arm member is formed into a yoke shape. A reduction gear is inserted and attached to the shaft hole formed in the left and right hollow shafts, and the base end of the driven side arm member is fitted into the yoke opening of the drive side arm member. The driven side arm member is supported in a dual support structure by a member, and the driven side arm member is oscillated by a rotary drive device comprising a rotary actuator attached to the one hollow shaft member and the speed reducer. Features: A driving device for the working arm of construction machinery. (2) A pair of rotary drive devices consisting of the above-mentioned hydraulic actuator and reducer are symmetrically inserted into each hollow shaft member attached to the shaft holes of both yoke parts of the central opening formed at the tip of the drive side arm member. In addition to being fitted and attached, the base end of the driven arm member fitted into the yoke opening is supported by a dual support structure, so that the driven arm member is oscillated by the rotary drive device. A driving device for a working arm in a construction machine according to claim (1).
