Through the return visit of the customer, we found that although it was explained before, some people do not know much about the planetary gearbox, ignore some points that should be paid attention to, and cannot give full play to the performance of the reducer. Today, I will discuss with you the rotation accuracy of the planetary gearbox, hoping to help you.
Under the premise that the machining error of the planetary gearbox meets the requirements, the rotation accuracy of the reducer equipment largely depends on the internal bearings of the equipment. The key to adjusting the rotation accuracy of the planetary gearbox is to adjust the clearance of the bearings in the equipment. Maintaining a reasonable bearing internal clearance is of great significance to the working performance and bearing life of the reducer equipment components. For rolling bearings, if the reducer equipment works with a large gap, it will not only concentrate the load on the rolling element in the stress direction, but also cause serious stress concentration at the contact between the inner and outer rings of the bearing, thereby shortening the service life of the bearing. It will also cause the drift of the main axis, which is easy to cause the vibration of the planetary gearbox parts. Therefore, there is a certain amount of interference in the bearing inside the equipment, which leads to a certain elastic deformation at the contact between the rolling elements and the inner and outer rings, so as to improve the stiffness of the bearing. Among them, the error of matching parts and their assembly quality have a significant impact on the transmission accuracy. In the work of the transmission parts, due to heating and force, it is inevitable to cause deformation, which will also have a certain impact on the transmission accuracy of the transmission chain.
In fact, there are many reasons that affect the accuracy of planetary gearboxes. The above is a brief analysis of the internal bearings of the equipment, which can be used as a reference.
