通常,在链传动中需设置张紧装置,用以调整中心距的变动,补偿中心距的误差及链条在使用过程中的磨损伸长。特别是在链轮中心距需要经常变动的情况下,设计链传动的自动补偿张紧装置,更是必不可少的。目前各类机械中常用的自动张紧装置主要是利用弹簧的自动调节作用来设计的。这里介绍另一种新颖的弹性自动补偿张紧装置。其结构如图1。张紧座1紧固在机架5上,支臂2的外
Normally, a tensioning device needs to be set in the chain drive to adjust the variation of the center distance, compensate the error of the center distance and wear elongation of the chain during use. Especially in the sprocket center distance needs to be changed frequently, the design chain drive automatic compensation tensioning device is even more essential. At present, the automatic tensioning device commonly used in various types of machinery is mainly designed by using the automatic adjustment function of a spring. Here is another novel flexible automatic compensation tensioning device. The structure shown in Figure 1. Tension seat 1 is fastened to the frame 5, the outer arm 2
