ROTATING TYPE QUICK COUPLER FOR EXCAVATOR

摘要

The present invention relates to a rotary quick coupler for an excavator. The upper coupling part is connected to the arm of the excavator. The lower coupling portion is disposed to be spaced downward from the upper coupling portion, and the attachment is attached and detached. The power transmission part is fixed to the lower surface of the upper coupling part, the protruding block is fixed to the upper surface of the lower coupling part, and the upper and lower flanges protrude along the outer circumference to enter the upper and lower sides of the protruding block. It includes a rotation transmission body, and a sliding bearing for rotationally supporting the rotation transmission body with respect to the housing. The drive unit rotates the rotation transmission body. The clearance adjusting unit supports the lower surface of the housing and the upper surface of the lower coupling unit by adjusting the clearance generated between the lower surface of the housing and the upper surface of the lower coupling unit.
