夹板锤普遍存在着锤杆使用寿命短的弊病.我们在多次观察中发现,提升机构是关键部位,提升轮在没有做提升动作前,首先要空转一段时间,直径200多毫米的提升轮是偏心的,就产生了空转时的不稳定和离心力不断增加的现象,这是造成提升机构零件磨损的一个主要原因.因提升轮是偏心的,其与传动主轴的配合只能采用滑动轴承(钢套见图1).这种结构密封条件差,加上工作条件恶劣,钢套磨损加快,这是提升机构零件容易磨损的第二个原因.由于以上两个原因,使两提升轮之间的距离发生变化,提升动作
Plywood hammers commonly exist shortcomings of hammer life is short .We have observed in many times found that the lifting mechanism is the key part of the lifting wheel in the absence of lifting action, we must first idling for some time, the diameter of more than 200 mm lifting wheel is Eccentric, resulting in instability when idle and increasing centrifugal force phenomenon, which is caused by the lifting mechanism parts wear a major reason for the lifting wheel is eccentric, with the drive spindle can only use the sliding bearing (steel Set see Figure 1) .This structure is poor sealing conditions, coupled with poor working conditions, steel sleeve wear and tear, which is to enhance the body parts easy to wear the second reason.For these two reasons, so that the two lifting wheels The distance changes to enhance the action
