Embodiment Construction

[0047] As mentioned in the background art, the accuracy of life estimation of existing transmission components needs to be improved.

[0048] In the embodiment of the present invention, multiple cumulative loads of the transmission component are obtained by calculating the cumulative load corresponding to each position interval of the multiple position intervals of the transmission component, and the cumulative load is the cumulative load of the transmission component up to a specified time The sum of the loads; based on the numerical relationship between multiple cumulative loads of the transmission component and the life threshold of the transmission component, the remaining life of the transmission component after the specified time is obtained, and the life threshold is the Load upper limit setting value for transmission components. In this process, by calculating the multiple accumulated loads of multiple position intervals of the transmission component, the force of the ...

Abstract

The embodiment of the invention discloses a service life estimation method and device, a medium, a terminal and a servo feeding system, and the method comprises the steps: calculating the cumulative load of each position interval in a plurality of position intervals of a corresponding transmission part, and obtaining a plurality of cumulative loads of the transmission part, wherein the cumulative load is the sum of loads accumulated to a specified moment by the transmission part; and based on the numerical relationship between the multiple accumulated loads of the transmission part and a life threshold value of the transmission part, obtaining the remaining life of the transmission part after the specified moment is obtained, wherein the life threshold value is a load upper limit set value of the transmission part. According to the technical scheme, the accuracy of estimating the service life of the transmission part can be improved.

Description

technical field [0001] The invention relates to the field of machining, in particular to a life estimation method and its device, medium, terminal and servo feed system. Background technique [0002] With the development of numerical control systems, numerical control machining technology has become more and more popular, and numerical control machining is a very important link in modern machining. [0003] Fatigue damage is a common cause of failure of transmission components in CNC systems. Accurately estimating the remaining life of transmission components has important theoretical significance and engineering practical value for eliminating hidden dangers of accidents in NC machining, formulating effective maintenance plans and prolonging the service life of transmission components. [0004] The accuracy of life estimation of existing transmission components needs to be improved. Contents of the invention [0005] The technical problem solved by the embodiments of th...
