Description

Inner core and bearing integrated universal wheel Technical Field The application relates to the technical field of caster manufacturing, in particular to an inner core and bearing integrated universal wheel. Background With the rapid development of modern industry and logistics industry, the demands of various devices, furniture and transportation tools for convenient movement and flexible positioning are increasing, and casters are widely applied in a plurality of fields as key components for realizing convenient movement and fixation of objects. The casters are mainly divided into movable casters, fixed casters and movable casters with brakes. The movable castor can realize 360-degree free rotation, is suitable for a scene needing flexible direction change, can only move along a straight line, is commonly used for equipment with specific requirements on the moving direction, has the functions of free movement and reliable braking, and can provide effective guarantee when a temporary fixed position is needed. The assembly process of the conventional castor has obvious defects that the conventional castor is required to be respectively purchased with a plurality of parts such as a bearing, a castor inner core and the like, the complicated part system not only increases the management cost of a supply chain, but also makes the assembly process become lengthy and complex, and particularly, the bearings are manually added to the two sides of the castor inner core, so that a great deal of labor and time cost are consumed, the assembly process has extremely high requirements on precision, and the castor is required to be subjected to the assembly mode, so that the bearing has a falling risk in the long-term use process of the castor, the normal operation of the castor is influenced, and therefore, the optimization design and the assembly scheme are urgently needed through technical innovation.
