System for connecting oil-lubricated kinematic modules, especially industrial robot gear and / or bearing modules, method of kinematic module lubrication

摘要

Oil charge of at least two kinematic modules (1) in different axes of the industrial robot is interconnected by the oil line (2) into the closed oil circulation between the interconnected kinematic modules (1). In a preferred embodiment it has the pump system (3) connected to the oil extrusion to the above-mentioned kinematic module (1) and also has a filter device (4) for filtering the oil in the circulation circuit or in a separate circuit with the oil tank (9). The system may also comprise at least one diagnostic element (5), for example an oil temperature sensor and / or an oil pressure sensor, and / or an oil contamination sensor connected to the evaluation unit (6). The evaluation unit (6) can be connected to an industrial robot control system, whereby the oil management is controlled and planned depending on the actual load of the individual kinematic modules (1). Said arrangement achieves a condition in which the oil from the kinematic module (1) is circulated in common with the oil from another kinematic module (1), whereby the pump system (3) is cleaned by means of a filter device (4).
