Title:
INDUSTRIAL ROBOT
Document Type and Number:
WIPO Patent Application WO/1985/002577
Kind Code:
A1
Abstract:
A high-performance dust-free industrial robot. Rotary, slide and contact portions of structural members which in combination constitute a robot, such as arms, articulated members, bearings and drive sources, are substantially hermetically sealed such as to be shut off from the outside air by means of the above-described arms, articulated members, bearings or a cover, or a combination of these members, for example, a combination of a fixed-side arm (3), a driven-side arm (4) and bearings (7), (8), whereby an internal space is formed. In addition, the internal air pressure is made lower than the external air pressure, whereby the dust which is generated when the robot is operated is prevented from scattering outside the robot.
