On the issue of predicting the durability indicators of aservo drive power reducer

An algorithm for calculating the operating time before failure of a servo drive reducer during its operation is proposed. The results of operating time calculation, performed using a method that differs from the known ones by representing the failure rate of a power reducer as the sum of two components proportional to the square and logarithm of the torque at the reducer output, are presented. The proposed approach will allow moving from the concept of operating servo drives according to the assigned resource to the concepts of operation according to predicted indicators of failure-free operation and durability.
