Abstract: In order to ensure that the lifting force of the clamping friction overspeed governor can meet the needs of the safety gear, the lifting force of the clamping friction overspeed governor should be calculated and analyzed. This paper simplifies the calculation model for the pull force of a clamp-type friction speed limiter, yielding simplified results for pull force calculation. The finite element modeling is established, the transient dynamic analysis is carried out, the calculation results of stress and displacement are obtained. This paper analyzes the relationship between the lifting force and clamping force, summarizes the factors affecting the lifting force of the clamping friction overspeed governor, takes corresponding preventive measures, and provides corresponding references for the maintenance and inspection of overspeed governor and safety gear.
