Probability of the Critical Length of a Fatigue Crack Occurring at the Tooth Foot of Cylindrical Geared Wheels of the Drive System of a Fiomax 2000 Ring Spinner

Abstract: In the present paper, we describe a method of determination of the probability of reaching the critical crack length at the tooth root of the cylindrical geared wheels of the drive system of the Fiomax 2000 ring spinner. The Paris-Erdogan formula was utilised for calculations of the fatigue crack length depending on the number of load cycles. Experimental investigations were performed on cylindrical geared wheels. The wheel specimens were manufactured from 1.6523 steel (UE) according to a technical specificati… Show more

“…This phenomenon occurs usually in the case of loadings lower than the ultimate strength. The basic characteristics -which are used for further analyses -are versatile charts; but mainly the Wöhler chart is utilised, also called an S -N (σ -S) curve or Wöhler diagram (Figure 1) [3,[11][12]. It allows determination of the maximal loading level (σ), for which a specimen made of a particular material can work within the range of an unlimited number of cycles (N).…”

“…Summarizing, the stretching apparatus should be considered as an essential part of the spinner drive system, therefore frequent changes in the rotational velocity have a direct influence on the dynamic character of load variability. The role of the stretching apparatus is the setting of tensions [11] via a system of co-operating geared wheels.…”
