Considerations Concerning the Oil Viscosity Influence on Textile Spindles Dynamic Response


Abstract:
Dynamic complex phenomena due to specific running conditions for textile spindles such as speeds, unbalanced yarn bobbins, their attachement to the ring frame, types of spindle bearing units, are the main causes of significant modification in time for running parameters with important implications in unwished efect appearance. In this way, the paper presents some aspects concerning the oil viscosity influence both on rotative spindle+yarn bobbin system dynamic response with the help of double amplitude measuring for spindle rod and on running power consumption of textile spindles. The experimental researches make evidence on textile spindles vibration amplitudes increasing with oil viscosity decreasing, but power consumption increasing in corellation with oil viscosity increasing too; these aspects have a negative influence on running dynamic stability. The experimental results presented as influence diagrams contribute to establish an important data base which will help in taking adequate decisions for oil viscosity selection necessary to textile spindles. Keywords: oil, viscosity, textile spindle, dynamic response, power consumption
