Problems solved by technology
[0007] However, because the historical service life estimation in the prior art only takes into account the external factors applied to the transmission mechanism such as load and rotational speed, but does not take into account the local defects of the transmission mechanism itself (such as wear, corrosion or cracking of individual meshing teeth, etc.) The resulting damage to the entire historical service life of the transmission mechanism; and because the local defects of the transmission mechanism itself usually cannot be reflected in factors such as external load and speed, it may even make the external load or speed lower than normal, thus affecting estimates of historical useful life
Therefore, it is difficult to accurately estimate the historical service life of the transmission mechanism solely relying on external factors such as load and rotational speed applied to the transmission mechanism.

Embodiment 1
[0105] figure 2 It is an exemplary flow chart of a method for determining the end of service life of a transmission mechanism in Embodiment 1 of the present invention. Such as figure 2 As shown, the process includes the following steps:
[0106] Step 201, monitor the parameters during the operation of the transmission mechanism, and generate the load of the transmission mechanism driver according to the operating current or torque of the transmission mechanism driver in the monitored parameters and the movement position information of the transmission mechanism when the preset time interval is reached waveform.
[0107] In this step, the load information during the operation of the transmission mechanism can be reflected in the operating current or torque of the transmission mechanism driver, and the movement position information of the transmission mechanism can be obtained from the feedback of the position measurement system of the transmission mechanism. The operating cu...

The invention discloses a method for determining the service life terminal and estimating the current historical service life and a system thereof. The method for estimating the current historical service life comprises the following steps: driver load waveforms are generated according to the load information and the movement position information of a transmission mechanism; the current historical service life weight coefficients of the transmission mechanism are acquired according to the driver load waveforms; the weight coefficients are used for weighting and calculating the current initialhistorical service life of the transmission mechanism, thereby acquiring the current historical service life of the transmission mechanism. In the method for determining the service life terminal, aninitial value of the previous accumulated historical service life is set in advance; the current historical service life is added to the previous accumulated historical service life; the sum is compared with the set estimated expected service life of the transmission mechanism; whether the transmission mechanism reaches the service life terminal is determined. By adopting the technical proposal of the invention, the accuracy of the estimated historical service life of the transmission mechanism can be improved.
Description
technical field [0001] The present invention relates to the mechanical field, in particular to a method and system for determining the end of service life of a transmission mechanism, and a method and system for estimating the current historical service life of a transmission mechanism. Background technique [0002] In the machining process, a huge workload is imposed on the transmission mechanism, so the wear and tear of the transmission mechanism will directly reduce its service life, and when the transmission mechanism reaches its service life, it needs to be replaced immediately, otherwise it will be damaged. It may affect the stability of processing quality and may damage other components connected to it. For this reason, it is necessary to set the expected service life of the transmission mechanism in advance, and calculate the historical service life of the transmission mechanism in real time, that is, the consumed service life. When the historical service life of the...
