LUBRICATING OIL SUPPLY UNIT OF ROBOT ARM

摘要

PURPOSE: A lubricant supply device for a robot arm is provided to prevent the interference, abrasion, and loosening of a hose line and ensure smooth supply of lubricant because of the minimized length of the hose line. CONSTITUTION: A lubricant supply device for a robot arm comprises a lubricant pump(120), a supply pipe(130), and horizontal and vertical rotating connectors(140,150). The lubricant pump supplies lubricant to a joint(112) of a robot arm. The supply tube, through which the lubricant supplied by the lubricant pump is moved, comprises a metal pipe(132) which is arranged in a robot arm body(114) and a flexible hose(134) which is arranged on the joint of the robot arm. The horizontal and vertical rotating connectors are connected to the supply pipe and installed in joints which rotate in the horizontal and vertical directions of the robot arm.
