很多人都想知道渔线轮轴承的每一个细节,包括它是如何制作而成的,它在渔线轮的运作过程中扮演怎样的角色,它的数目多少意味着什么,它的内部结构是怎样的……对于一些喜欢自己亲手维护渔具的钓友们来说,了解轴承的结构,是维护渔线轮所必须掌握的知识。正如禧玛诺公司的渔线轮设计专家杰里米·斯威特所说的:“清楚地了解滚珠轴承,有助于钓手在购买渔线轮时做出更好的决定。” 相似文献

This paper presents the research on the laws of systematic-parameter dependent variation in the vibration amplitude of drum-brake limit cycle oscillations (LCO). We established a two-degree non-linear dynamic model to describe the low-frequency vibration of the drum brake, applied the centre manifold theory to simplify the system, and obtained the LCO amplitude by calculating the normal form of the simplified system at the Hopf bifurcation point. It is indicated that when the friction coefficient is smaller than the friction coefficient at the bifurcation point, the amplitude decreases; whereas with a friction coefficient larger than the friction coefficient of bifurcation point, LCO occurs. The results suggest that it is applicable to suppress the LCO amplitude by changing systematic parameters, and thus improve the safety and ride comfort when applying brake. These findings can be applied to guiding the design of drum brakes. 相似文献
