本文叙述了在试验室和质量检验中测定径向负荷的一个新装置.导出了求径向负荷的方程式,叙述了材料和密封件尺寸对径向负荷的影响.由于工作条件引起的径向负荷的显著变化能够导致密封性能的破坏.在设计密封件之前应认真考虑工作条件.随着车辆、机械、飞机对改善可靠性和延长使用寿命的要求,也就增加了对油封的要求.近年来,由于要求较高的速度和较高的温度,压力的要求也随之增加.与此同 This paper describes a new device for measuring radial load in laboratory and quality testing. The equation for calculating radial load is derived and the effect of material and seal size on radial load is described. Due to the radial load caused by operating conditions Significant changes can lead to the destruction of the sealing performance in the design of the seal should be carefully considered before working conditions with the vehicles, machinery, aircraft to improve reliability and extend the life of the request, it increased the requirements of the oil seal in recent years , The pressure requirements also increase due to the higher speed and the higher temperature requirements
