Method and a system for establishing and executing correct automatic relubrication for a number of bearings

A system for establishing and executing correct automatic relubrication for at least one bearing incorporated in a grease lubrication system, the system comprising:

• a central processor unit,
• a number of sensors provided in connection to the at least one bearing and adapted to measure at least one of a temperature, a load and a rotational speed for the at least one bearing, thereby collecting current data,
• a communication interface for transferring the current data from the sensors to the central processor unit wherein the current data measured by the sensors includes bearing load, bearing temperature and bearing rotational speed are collected from during operation,
• an instruction set providing operational directions to the central processor unit, the instruction set including
• an instruction step of utilizing the current data collected from the at least one bearing for calculating a current anticipated value for a current relubrication interval,
• an instruction step of comparing the current anticipated value with a last calculated preceding anticipated value to generate a current anticipated relubrication interval,
• an instruction step of calculating a correct lubricant volume based on the current anticipated relubrication interval, and
• an instruction step of comparing the current anticipated relubrication interval with an actual time;
• and
• an automatic lubrication apparatus in communication with the central processor unit, the automatic lubrication apparatus arranged to feed out a correct volume of grease to the at least one bearing when the current anticipated relubrication interval is less than or equal to the actual time.
