Title:
ROTATION LINK FOR OPERATION MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/199596
Kind Code:
A2
Abstract:
The present invention relates to a rotation link for an operation machine and, more particularly, to a rotation link for an operation machine configured to efficiently accomplish prevention of mechanical wear of a rotation link for rotating a constituent element of an operation machine such as an excavator, prevention of detachment of a fastening element due to biased arrangement of a rotation driving element, and braking of the rotation driving element. A rotation link for an operation machine according to the present invention is characterized by comprising: a rotation motor; a driving gear that receives rotational power generated by the rotation motor; a lower gear coupled to the driving gear so as to convert vertical rotation of the driving gear into horizontal rotation, a braking groove being formed on the lower gear; an upper plate coupled to the lower gear with a ball bearing interposed between the same; and a braking portion fixed to the lower side of the upper plate and coupled to the braking groove of the lower gear or separated from the same, thereby suppressing the horizontal rotation of the upper gear or allowing the same.
