我公司ZK-6/100型电机车四个轮轴处,轮轴与封环结合没有密封装置,仅在轴承盖与封环之间加油毛毡密封,油毛毡易磨损,造成渗油严重。据此,我们把原来的封环端面内孔加工成一个小圆弧,增装了一个O 形圈,并把原来轴承盖的油毛毡密封改成耐磨、密封性能好的油封,改进前后如图所示。经过改装后沿用至今已有一年,没有发生轮轴处渗油现象,取得了较好的治漏效果。 ZK-6/100 electric locomotive company four axles, the wheel shaft and the seal ring with no sealing device, only between the bearing cap and sealing ring refueling felt seal, easy to wear oil felt, resulting in serious oil leakage. Accordingly, we have the original seal ring end face hole into a small arc, an additional O-ring, and the original bearing cap oil felt seal into a wear-resistant, good sealing performance of the oil seal, before and after the improvement shown As shown. It has been used for a year now after modification. No oil leakage occurred at the wheel shaft and good leakage control effect has been achieved.
