Lubrication system for kinematic modules, preferably transmission modules or industrial robot bearings, and method for lubricating the kinematic module

摘要

The oil content of at least two kinematic modules (1) in different axes of the industrial robot is connected by the oil line (2) to the closed circuit of the oil between interconnected kinematic modules (1). In preferred arrangement, the system includes the pump (3) engaged in pushing the oil in the upper-mounted kinematic module (1) and also the filtration device (4) for filtering the oil in the circulating circuit or in a separate circuit with the oil tank (9). The system may also include at least one diagnostic element (5), for example an oil temperature sensor or an oil pressure sensor or an oil pollution sensor connected to the evaluation unit (6). The evaluation unit (6) can be interconnected with the industrial robot control system, whereby the oil economy is controlled and planned depending on the actual load of the individual kinematic modules (1). By this arrangement, you can achieve the condition in which the oil from the kinematic module (1) circulates in shared circulation with the oil from another kinematic module (1), whereas the oil gets purified through the filter device (4) by using the pump (3).
