摘要
介绍了惯性振动设备用箱式激振器结构部件（ 包括轴承装置、偏心块结构和激振器座结构） 的设计方法和原则，激振器所用轴承为大游隙普通调心滚子轴承，轴承外圈公差配合采用具有较大过盈量的 Ｐ 级或 Ｎ 级配合，内圈采用ｈ 级配合．轴承润滑采用锂基脂润滑剂，密封采用迷宫、毡圈、唇形密封圈．激振力的调整方法有３ 种，分别为调整偏心块重量、偏心距的大小及同时调整偏心块的重量及偏心距．双轴激振器的同步一般采用自同步方式．据此设计的激振器，经现场使用。
This article introduces the design methods and principle of construction of box vibrating(including bearings set,eccentric block and vibrator stand).The bearings used in box vibrator is big play common center-adjusting roller bearing.The degree of fit of outer surface is P or N,inner surface is h.The lubricant is Li-base lubricant.The method of seal is felt ring or maze gap or lip seals or combining seals.The adjusting methods of vibrating force have three kinds: adjusting weight of eccentrc block、eccentric distance and adjusting weight and distance at the same time.The synchronizing method used in double shaft is self-synchronization.The vibrator designed according to the above principles prove to be excellent.
