在拖车使用中,常发现拖车车轮晃动、轮轴弯曲、轴承早期损坏等故障,究其原因,多是机手没有按时检查、调整、润滑或拖车超载所致。其后果,轻者使轮轴轴承、轮胎等零件早期损坏;重者造成车轮飞出或断轴等事故。因此,必须重视拖车轴承的保养。拖车轮轴上装有两只圆锥滚子轴承,是止推轴承,既能承受轮轴上的径向力,又可承受一定的轴向力。轴承的间隙采用调整螺母调整,一般间隙要求在0.1～0.3毫米。新拖车经过一段时间的磨合后,应检查调整轴承间隙并更换润滑脂。拖车使用500小时左右,
In the use of the trailer, often found trailer wheel shaking, axle bending, early damage to bearings and other failures, the reason is mostly due to lack of timely inspection, adjustment, lubrication or trailer overloading caused. The consequences, the light of the wheel bearings, tires and other parts of the early damage; severe cases caused by the wheel out or broken shaft and other accidents. Therefore, we must pay attention to the trailer bearing maintenance. Trailer axle equipped with two tapered roller bearings, thrust bearings, both to withstand the radial forces on the wheel shaft, but also can withstand some axial force. Adjust the bearing clearance adjustment nut, the general gap requirements of 0.1 ~ 0.3 mm. The new trailer after a period of running-in, you should check the adjustment of bearing clearance and replace the grease. Trailers use about 500 hours,
