The guide wheel is mainly used to guide the track to wind correctly, and to prevent its deviation and deviation.   At the same time, the guide wheel and the tension device work together to adjust the tension of the track, mitigate the impact force from the road when moving forward, and reduce the vibration of the fuselage.   Therefore, the guide wheel is essential in the chassis movement. Operational hour   When working, the guide wheel is easily covered with mud, stones and other debris. If not cleaned up in time, these debris will affect the normal work of the guide wheel, and even damage the wheel body. The operating habits of daily work will also have a greater impact on the wear of the guide wheel. In short, the maintenance of the guide wheel is of great significance to ensure the normal work and extend the service life of the tracked construction machinery.   It should be cleaned regularly, checked for wear and seal status, and pay attention to operating habits to ensure that the guide wheel is in good working condition.   Bear in mind   Keep good habits   For example, walking on inclined ground for a long time and turning suddenly will make the side of the rail link contact with the side of the drive wheel, the guide wheel and the support wheel, which will aggravate the side wear of the wheel edge.   Therefore, long-term slope operation and sudden turning should be avoided as far as possible, and the use of straight line travel and large turns can effectively reduce wear.   After job   After each work, it is recommended to clean the guide wheel with clean water to remove debris and dirt on the surface. The normal operation of the guide wheel is required to have a good seal and internal lubrication.   Bear in mind   Periodic lubrication maintenance   Check the guide wheel float seal and shaft head seal regularly to ensure the seal status inside the guide wheel and ensure good lubrication between the guide wheel shaft and the plain bearing sleeve.   Once the guide wheel seal failure is found, the seal should be replaced or repaired in time to avoid abnormal wear between the wheel shaft and the sleeve due to leakage, and then lead to damage to the guide wheel. When the guide wheel is working for a long time, the tread of the wheel body and the part of the wheel rim will have different degrees of wear.   Bear in mind   Timely replacement   If the guide wheel with serious wear is not replaced in time, it will lose its original effect and even affect the normal operation of the equipment.   Therefore, in each maintenance, it is recommended to check the wear of the guide wheel, and once the guide wheel is found to exceed the wear limit standard, it should be replaced in time.
