Oil-lubricated kinematic module connecting system, mainly the transmission or bearing modules of industrial robot; method of kinematic module lubrication

A system for interconnecting oil-lubricated kinematic modules of an industrial robot, including transmission or bearing modules of the industrial robot, the system comprising:

• at least two kinematic modules (1), wherein each one of the kinematic modules (1) comprises an oil-filled box for lubricating or cooling moving parts of the kinematic module (1), wherein the kinematic modules (1) are located in different axes of the industrial robot,
• an oil content of the at least two kinematic modules (1) is connected by an oil line (2) forming to a closed oil circuit of an oil between the at least two interconnected kinematic modules (1),
• an oil pump (3) connected to a lower cart of the system;
• and the system includes a filtration device (4);
• wherein the filtration device (4) includes a replaceable filtration element (8), a bypass pressure valve;
• a pressure sensor to measure a permeability of the filter, and a suction filter (12) for coarse mechanic impurities.
